BookItem Open Access A Book of Theses Abstracts: Doctoral Degree(Bihar Agricultural University, Sabour, Bhagalpur, 2023) Haque, Mizanul; Sharma, R.P.; Singh, A.K. and Kumar, RajeshBookItem Open Access A Book of Theses Abstracts: Master’s Degree(Bihar Agricultural University, Sabour, Bhagalpur, 2023) Haque, Mizanul; Sharma, R.P.; Singh, A.K. and Kumar, RajeshThesisItem Open Access Adsorption-Desorption behaviour of sulphur under conservation agriculture(Department of Soil Science and Agricultural Chemistry, BAU, Sabour, 2020) Kumari, Kirti; Shambhavi, ShwetaSulphur is the essential secondary macronutrient element required for optimum growth, metabolism and development of all plants and is rightly called as fourth major plant nutrient. It is essential for synthesis of amino acid like methionine, cystine and cysteine and resembles Nitrogen for many functions in plant and synergistic to N fixation and nodule development in legume. In soil S mostly remains in organic combination, constituting more than 95 % of total sulfur. Sulphate sulfur is the form plant prefers to uptake and its availability depends upon the mineralization of organic sulfur in soil. Soil tillage is the basic and key to reducing soil-related constraints in crop production. It has a long-term effect on soil properties and crop growth. CA systems are currently being practiced on a wide range of soil types, environments and numerous crops and cropping systems. Because of the possibilities to increase productivity and improve soil health, CA becomes a crucial part of the national polices for an agricultural production system. Adsorption desorption characteristics are useful for describing, studying and managing the sulfur status of soils.The concentration of sulphate in soil solution, as predicted by sulphate sorption-desorption curve provides a valuable information on sulfur availability to crop plants. The experimental soil was sandy loam in texture, neutral in reaction, low in N, medium in organic carbon and K and high in available P. As per taxonomic classification the soil falls under the order “Inceptisols”. The soil samples from the depth of 0-20 cm was collected from the field experiment on conservation agriculture with six maize based cropping systems and three tillage practices laid out in split plot design with tillage practices being main plot and cropping system in sub-plots replicated thrice. The samples were collected before Maize in Kharif 2019 and analysed for various soil physico-chemical properties, available N, P and K, total N, free Fe and Al oxides as well as different forms of sulphur and adsorption and desorption behaviour of sulphur in soil. Continuous practice of reduced tillage and different cropping systems led to improvement in soil physico-chemical properties such as soil pH, OC, available N, P, K, S, total N, and free iron and aluminum oxide. Among the different forms of sulphur studied it was found that all the forms were higher under zero tillage and soybean-maize cropping system except adsorbed sulphur which was higher under conventional and maize-maize cropping system. Available Sulphur, Water soluble sulphur (WSS), Heat Soluble Sulphur (HSS), Adsorbed Sulphur (AdS) and Organic sulphur (OS) was on an average 3.99, 3.57, 11.38, 3.67 and 64.06 %, respectively of Total Sulphur. Amongst all the forms studied, Organic Sulphur was the most dominant form of Sulphur. Maize yield and uptake was found to have positive and significant correlation with all the forms of S except adsorbed as it’s not a bioavailable form. The adsorption data was best fitted in Langmuir equation as per the R2 values are concerned. The adsorption maxima followed the order CT>PRB>ZT under tillage system and for cropping system the highest adsorption was in maize-wheat system. The adsorption data also fitted well in Freundlich isotherm having higher R2 values. The extent of adsorption followed similar order as observed as that in case of adsorption maximum under Langmuir isotherm. In terms of adsorption maxima (Langmuir) and the extent of adsorption (Freundlich) the tillage practices followed the order CT>PRB>ZT while cropping systems were in the order of C2>C5>C3>C4>C1> C6.While, desorption of S was observed to be minimum under CT followed by PRB followed by ZT. While in terms of cropping system, the minimum was in maize-maize while maximum under soybean-maize across all tillage systems. It can be concluded that zero tillage and soybean-maize cropping system performed better in increasing the sulphur status of soil and the linear plot of the adsorption data were good fitted in both Langmuir and Freundlich equation with best fit in Langmuir equation.ThesisItem Open Access Analysis of genetic diversity of litchi (Litchi chinensis Sonn.) hybrids using morphological and molecular markers(Department of Horticulture (Fruit & Fruit Technology), BAU, Sabour, 2016-07) Kumari, Abha; Mankar, AbhayLitchi (Litchi chinensis Sonn.) is an economically important fruit tree of family Sapindaceae and native to southern China. Evaluation and characterization provide a rapid, reliable and efficient tool of information to exploit genetic variability and to augment the utilization of germplasm, but differentiation of cultivars through morphological features is inefficient and inaccurate. Hence, molecular markers with support of morphological analysis have been allowed to solve the problem of cultivar identification and analysis of genetic diversity. Keeping this information in mind, the present investigation was framed with objectives (i) Characterization of litchi hybrids by using morphological and biochemical analysis. (ii) Genetic Diversity analysis of litchi hybrids using molecular marker. The study was accomplished by using 18 hybrid litchi in horticulture garden, BAC, Sabour, during 2014-15.The morphological analysis revealed that sufficient genetic variability was present among the hybrids which provide ample scope for selection of promising hybrids under study. D2 cluster analysis grouped the eighteen hybrids into 5 clusters. The inter and intra cluster distance between the hybrids under study indicate the existence of higher level of genetic divergence among themselves. The highest inter cluster distance was observed between cluster II (comprising of H-104, H-141(W), H-503) and cluster V (comprising of H-580, H-711), whereas, intra cluster distance in cluster III (comprising of H- 141(E), H-517, H-140, H-573) which suggest that selection of promising hybrids of these clusters may lead to creation of variability. H-515 was concluded as superior hybrid among all hybrids in term of fruit weight (26.27 g), aril weight (18.78 g), fruit length (35.60 mm), fruit diameter (35.21mm), aril percentage (71.20%), aril seed ratio (5.46). Hybrid H-104 was found best in term of TSS (22.000 Brix). Morphological traits are not always good indicators of the genotype. Moreover, there is widespread confusion over the identities of litchi cultivars that have been identified only by their morphological traits. Hence, Identification through only morphological characters may lead to unreliable determination due to environment influence. So, Genetic fidelity and similarity within hybrid litchi were investigated using SSR (simple sequence repeat) and RAPD (random amplified polymorphic DNA) markers. SSR markers studied reflected no polymorphism whereas Sixteen RAPD, resulting in amplification of 71 reproducible polymorphic fragments products. The percentage of polymorphism for RAPD was 68.93%.Range of similarity coefficient varies from 0.506-0.922. H-104 and H-141(W) appears to be very similar both morphologically and genetically whereas two hybrid litchi (H-524 and H-580) were found to be genetically very distant from the other. However molecular analysis revealed very narrow genetic diversity among the hybrids of litchi which concludes that diversity observed through morphological analysis may be influenced by the environmental factors.ThesisItem Open Access Analysis on Variability of Sclerotium rolfsii Causing Cucurbit Collar Rot(Department of Plant Pathology, BAU, Sabour Year: 2017, 2017-07) Kumar, Ritesh; Bhagat, A. P.Cultivation of cucurbits is largely affected by several biotic factors. Among diseases, collar rot causes significant damage to cucurbits and ultimately responsible for yield loss. Despite being a dreaded pathogen having wide host range (infects over 270 families of plants); the collar rot dynamics in cucurbits is untouched. Therefore, this study envisaged with collecting the preliminary information regarding to this pathosystem. Collar rot of cucurbits is caused by Sclerotium rolfsii Sacc., a soil inhabitant and non-specific facultative parasite that found in almost all types of agro-ecological systems. At first, the collection of isolates from various hosts and locations of Bihar was made. These isolates were addressed to morphological and biochemical variations. Great variability of isolates from different localities was observed. Additionally, the collected isolates showed variation in melanin production. An isolate, producing highest number of sclerotia (117/plate), was selected for the tests of fungicidal sensitivity and temperature adaptability. The fungicide belonging to sterol biosynthesis inhibition exhibited great potential to reduce the fungal growth. Therefore, new fungicide involving hexaconazole along with the common fungicide used for Sclerotium rot management, carbendazim, should be synthesized. The isolate adapted to high temperature (35°C) after 8th sub-culturing indicating the adjustment capability of this pathogen towardselevated temperature. Therefore, the problem associated to this fungus may be increased in future, particularly under changing climate. Moreover, biochemical changes in the artificially inoculated plants were determined in different plant organs for the five isolates exhibiting high variability in the morphological observation. High content of total phenol and chitinase was detected at collar region; however, peroxidase estimation rendered non-significant (p≥0.01) variation amongst the plant organs. To address the varietal response and seasonal impact on collar rot epidemics the pot experiment has been conducted twice in a season (rainy and winter; 4 experiments in total) with cucumber and bitter gourd. Disease incidence (DI) calculated and area under lesion progress curve (AULPC) plotted in order to understand the collar rot dynamics in cucurbit. Additionally, measurement of lesion size was made. The varietal response has been found significant (p≤0.05) for the two crops. Overall, cucumber shown high susceptibility compared to bitter gourd in both of the seasons. The rainy season exhibited higher DI and AUDPC compared to winter season for both of the crops indicating high temperature is favourable to this pathosystem. Nearly similar trend was observed for lesion length for each condition. Wide variation among isolates and adaptability of the pathogen to high temperature suggesting to develop improved strategy for management. Development of fungicide with sterol biosynthesis inhibitors can be a reliable option to manage this pathogen. Delay sowing of cucurbits in rainy season would account for lower disease development; therefore, development of late sown varieties is suggested. If agroecosystem, and facility and economical status of the farmer allow the cultivation of cucurbit in summer season should be addressed particularly in areas with sporadic and epidemic history of collar rot.Item Open Access Annual Report DEE(BAU, Sabour, 2014) BAUItem Open Access Annual Report DEE(BAU, Sabour, 2014) BAUThesisItem Open Access Application of BBCH scale for phenological studies in litchi in relation to temperature(Department of Horticulture (Fruit Science), BAU, Sabour, 2022) Aman, Ankita; Rani, RubyLitchi (Litchi Chinensis Sonn.) of the sapindaceae family is one of the important sub-tropical fruit crops of India and require very specific climate for its successful condition. The growth, flowering and yield in litchi is greatly influenced by temperature. Phenology is the study of periodical plant development events and how they are affected by environmental conditions factors mainly temperature. In fact, changes in the time of phenophases of fruit trees are of great economical importance because they have direct impact on factors influencing final fruit yield. Phenological studies in litchi are also important for planned management of orchards and alerting litchi growers against environmental vagaries. BBCH-scale (BBCH = Biologische Bundesantalt, Bundessortenamt und Chemische Industrie) proposed by various workers has its own advantages of its simplicity and ease of use for annual, biennial and perennial plants and it also describes both the vegetative and reproductive stages of plant growth in sequential manner. Thus, an experiment was conducted to study the phenological development in litchi variety Deshi and Kasba using extended BBCH scale at experimental plot of Bihar agricultural University, Sabour that lies in indo gangetic plain of Bihar, India for three consecutive years from 2019 to 2021. The time, duration and prevailing temperature at each phenological stages of litchi were recorded as per extended BBCH scale in which 7 out of 10 principal stages were used, starting with bud development (stage 0) and ending with maturity of fruit (stage 8). Pictures of all phenophases were taken to see the morphological difference among them. Phenological development of all the stages of Deshi and Kasba was found significantly different in each year regarding their time of initiation and duration. The initiation of 1st vegetative flush started after 30-35 days in Deshi and 45-50 days in Kasba after harvest. The bud development (Stage 010) started in last week of June to first week of July in Deshi variety for 1st flush and first week of September for second flush. It was last week of July to first week of August in Kasba variety for first flush in both the year and first week of October for second flush. In variety Deshi phenological development was earlier in 2019 as Compared to 2020 and 2021 and it was delayed in 2020. Similar trend was noted in variety Kasba also. All stages of inflorescence were earlier in Deshi as compared to Kasba in each year of observation. It was also reflected that during 2020 all the mesostages was delayed in both the varieties. It was observed that prevailing temperature greatly influenced time and duration of particular phenophases in both the varieties. Positive correlation between maximum and minimum temperature with stages in both the variety was observed. Varietal difference was also observed in this regard and for stage 500, Deshi took higher temperature as compared to Kasba. However, all other stages, it was lower in Deshi as compared to Kasba. The principal stage flowering started earlier in Deshi than Kasba in all the years. But the phase duration of this stage did not vary much among the variety as it ranged from 30 to 32 days in Deshi and 28 to 33 days in Kasba during the year under study. Changes in leaf nutritional status in different phenological stages was also observed and highest Nitrogen (1.62 %) and Phosphorus content (0.27 %) was noted before beginning of stage 5 i.e. inflorescence stage and Potassium was maximum (1.25 %) at flowering stage. Similarly maximum carbohydrates (7.56 %) at stage initiation of stage 5 i.e. inflorescence stage. This study adds knowledge about year to year phenological development in relation to temperature. However, a long-term monitoring of litchi varieties for their phenophases and their relation to temperature is required to confirm the critical temperature for different phenophases and to see the phenological development in litchi with change in climate.ThesisItem Open Access Assessment of Genetic Diversity in Rice Genotype (Oryza sativa L.)(Department of Plant Breeding and Genetics, BAU, Sabour, 2018-06) Kumari, Shikha; Sinha, SimaThe present investigation was carried out to study “Assessment of Genetic Diversity in Rice genotypes (Oryza sativa L.)” in thirty five genotypes including three checks (Prabhat, MTU1010, Rajendra sweta) during Kharif 2017 at Rice research farm Bihar Agricultural University, Sabour, (Bhagalpur). Analysis of variance revealed significant differences among the genotypes for all the characters under study which indicated that considerable amount of variability were present in the genotypes included in the study. Hence, there is an ample scope for inclusion of promising genotypes in breeding programme for yield and its component characters. On the basis of mean performance the genotypes viz, LPD104-B-B-1-8-2-1-1, RP5124-11-6-2 were identified as the superior genotypes for yield and yield attributing traits .The higher magnitude of genotypic coefficient of variation was recorded for L/B ratio while, higher phenotypic coefficient of variation were recorded for grain yield per plant followed by kernel length suggested the presence of sufficient variability in genotypes which broaden the scope for genetic improvement through selection of these characters. High heritability coupled with high genetic advance as % mean was observed for kernel length ,L/B ratio which suggested that these characters can be considered as favourable attributes for the improvement through selection and this may be due to presence of additive genes effect and thus, could be improved upon by adapting selection without progeny testing. Grain yield per plant showed positive and significant association with biological yield per plant, days to 50 % flowering, days to maturity, while remaining characters showed non-significant association. Therefore, it is suggested that these traits should be used as selection criteria for yield improvement in rice genotypes. Path coefficient analysis revealed that biological yield per plant; harvest index and kernel length had high positive direct effects on grain yield per plant indicating true relationship of these characters with grain yield and direct selection. On the basis of Mahalanobis’s D² statistics, the genotypes were grouped into six clusters. The highest inter-cluster distance was observed between cluster III and and IV followed by cluster IV and VI and cluster IV and V ,which indicated maximum diversity between the genotypes of these clusters might be used in multiple crossing programme to recover transgressive segregants. Considering the genetic divergence and mean performance of genotypes for grain yield and other yield contributing characters, NDR9718 and BADSHAHBHOG-SBR-4 may be considered as divergent genotypes and hybridization involving these genotypes is likely to give desirable transgressive segregants for yield and yield contributing traits.ThesisItem Open Access Assessment of Genetic Potential for Submergence Tolerance in indica Rice (Oryza sativa L.)(Department of Plant Breeding and Genetics, BAU, Sabour, 2016-07) Singh, Rahul; Satyendra28 diverse rice genotypes including indigenous and exotic collections were screened for submergence tolerance at Research Farm of BAC, Sabour during Kharif 2015 with the help of morphological, biochemical and molecular studies aiming to reveal the effect of submergence on various morphological traits. It was also tried to know if the submergence tolerance, if any available, is due to SUB1 or there was any other gene responsible. The field trial was conducted with the same set of genotypes in control and submergence conditions simultaneously. One of the field trial was submerged completely at 30 DAT and remained submerged continuously for 18 days. Pre and post harvest data was collected for several important traits. Survival % was calculated in submergence experiment at 21st day of de-submergence. In biochemical study, ADH enzyme activity was analyzed while to work out allelic diversity, SSR primers were used. Gene specific primers for SUB1 were also used to confirm the presence of this QTL in the genotypes under study. Morphological data was subjected to statistical analysis for genetic variability, heritability, genetic advance, correlation coefficient, path analysis, and genetic diversity. Most of the yield contributing traits was drastically affected by the submergence. ADH was found to having a vital role for submergence tolerance in rice. Submergence tolerant genotypes, in general, has medium plant height and have no elongation ability during submergence due to which they show a better and balanced assimilation and consumption of carbohydrate. Out of 28 genotypes studied, three genotypes namely RYC-743, Purnendu, and IR 96321-315-402-B-1 can further be used as submergence tolerant genotypes.ThesisItem Open Access Assessment of N management strategy using SPAD meter for irrigated wheat (Triticum aestivum L.)(Department of Agronomy, BAU, Sabour, 2017-07) Prakash, Ved; Ghosh, MainakTop dressing of N fertilizer, whenever leaf greenness, as measured by Chlorophyll meter (SPAD), falls below the threshold value can be used for site-specific N management in wheat cultivation. Herein, an investigation was carried out to analyze the effect of SPAD based N management on wheat productivity and N use efficiency on alluvial soil of eastern India. In the experiment wheat was grown during the dry season (November to April) of 2015-16 in experimental farm of Bihar Agricultural College, Sabour, Bhagalpur. The experiment was laid out in split plot design with fourteen treatment combinations of two SPAD levels (42 and 44) as main plot and seven wheat cultivars (HD 2967, HD 2985, HI 1563, PBW 343, HW 1105, HD 3086 and Sabour Samriddhi) as sub plot treatments with basal dose of 40-60-40 kg N-P2O5-K2O ha-1 in three replications. The growth attributes in SPAD 42 are comparable with SPAD 44 in most of the cases, but using considerably less amount of N (19%) than SPAD 44. The growth and yield components are varied significantly among the wheat cultivars and in this regard cultivar HD 2967 and Sabour Samriddhi performed markedly over the others. The N management through SPAD based technology not only maintained the growth and productivity of wheat cultivars but can also be saved the N fertilizer when compared with state recommendation (120 kg N ha-1). The highest grain yield (5172 kg ha-1) was recorded in cultivar HD 2967 followed by Sabour Samriddhi (4817 kg ha-1) and both these cultivars were significantly superior over the cultivar PBW 343 which had scored the lowest productivity among the sub plot treatments. Similar trend was noticed in case of straw yield, where SPAD 42 and 44 were comparable likewise in grain yield. Study confirmed that chlorophyll meter based N management, especially maintenance of SPAD threshold value of 42 with N application of 20 kg ha-1 in each top dressing could save substantial amount of N along with the positive impact on grain yield. The leaf N content and SPAD value at CRI and tillering stages were linearly correlated and the optimum SPAD values for these growth stages were measured as 45.3 and 42.0, respectively for maximization of grain yield. The partial factor productivity of applied N (PFPN) decreased steadily with increasing the rate of N top dressing. The highest PFPN (54.05 kg kg-1) value was recorded in HD 2967, which was significantly superior over all other cultivars except HD 2985. Overall, HD 2967 recorded 12.8% higher value of PFPN than that of other cultivars. The internal N use efficiency (IEN) was also noted highest in HD 2967 (42.6 kg kg-1) and it was statistically superior over the Sabour Samriddhi which had noted the lowest IEN among the sub plot treatments. The highest gross (88215 Rs. ha-1) and net (56404 Rs. ha-1) returns were obtained in HD 2967 followed by Sabour Samriddhi and these cultivars were markedly higher over PBW 343 in both the cases. The maximum return per rupee invested in SPAD based wheat production system was also noted in HD 2967 (2.77) followed by Sabour Samriddhi (2.58). The productivity, N use efficiency and the economics i.e. gross return, net return and return per rupee invested remained non significant with the SPAD thresholds. Hence, from economic point of view SPAD 42 based N management strategy was found very promising in efficiently managing N fertilizer for maintaining wheat productivity and increasing N use efficiency in eastern part of India.ThesisItem Open Access Assessment of non-response in the estimation of population mean in sample survey(Department of Statistics, Mathematics and Computer Application, BAU, Sabour, 2017-08) Kumar, Sanjay; Homa, FoziaSample surveys are generally planned to obtain reliable estimates of parameters of the population. The mail questionnaire method is commonly used to collect data in surveys as the data collection costs following this method are considerably reduced. However, non-response can be a serious problem with this method of data collection. The presence of non-response may result in biased estimates, particularly, when the respondents differ from the non respondents. Although necessary steps are taken in situations where non-response is encountered, the problem persists. The presence of non-response not only introduces an element of bias in the survey results, but the estimators also become less precise. The presence of non-response may result in biased estimates, particularly, when the respondents differ from the non respondents. In this study, we have considered the problem of estimation of population mean in the presence of non-response. Accordingly, estimators were developed for the estimation of population mean. The proposed class of estimator was To deal with the problem of non-response, Hansen and Hurwitz (1946) developed new technique to estimate the population mean in case of missingness. This technique was based on the concept of sub-sampling of the non-respondents. A general class of modified ratio type exponential estimators was developed in the function of A and B which give eleven different estimators for different values of A and B. Properties of the developed estimators (biases, Mean Square Error’s (MSE’s)) have been studied and optimum mean square errors have been derived. The percent relative efficiencies of the proposed estimators have been studied empirically and found to be efficient as compared to sample mean estimator. There are many cases, when sub-sampling is not possible, so we imputed the missing value with some function of the responding class, developed by Rubin in 1987. The developed estimators have been checked in imputation technique and percent relative efficiency have been studied and found to be efficient as compared to the sample mean estimator. It is worthwhile to mention that simulations were performed involving population generated through gamma distribution.ThesisItem Open Access Assessment of quality and yield parameters in Katarni rice derived lines under different photoperiods(Department of Plant Breeding & Genetics, BAU, Sabour, 2023) Mahto, Divya; Singh, P. K.Rice is one of the major staple foods for more than 60% of the world population in general and South-East Asian people, in particular. However, very few high yielding non-basmati aromatic semi-dwarf rice varieties are available for cultivation. Katarni rice is traditional rice which is native of Bihar and extensively grown in few blocks of districts of Bhagalpur, Munger and Banka. This rice has a unique aroma with medium slender grain but it suffers from lodging problem due to weak culm and tall height (150-170 cm) which results in its low yielding (25-30 Q/ha) ability. Simultaneously, it is photosensitive with longer maturity period of 150-155 days. Hence in order to enhance its Farmers adoption a high yielding semi-dwarf and early maturing aromatic lines of Katarni is needed.To reduce the height and maturity period, a marker assisted backcrossing and forward breeding programme was initiated at Rice Section, BAU Sabour by crossing Katarni with two semi-dwarf and medium maturing rice varieties namely Rajendra Sweta, IR64 and MTU7029.Present study was undertaken to assess the genetic variability among the 54selected advanced breeding lines of Katarni along with parental checks i.e. Katarni, R. Sweta, IR64, MTU7029, Sabour Surbhit and Rajendra Suwasini at four different date of sowing in two years i.e. 2018 (DOS 1: 15-6-2018) and 2019 (DOS2: 29-5-2019, DOS3: 15-6-2019 and DOS4: 15-7-2019). In a trial conducted in Alpha Lattice (Incomplete Block Design), the analysis of variance (ANOVA) showed highly significant differences for all the traits among all the genotypes studied. Grain yield per plant had positive non-significant correlation with days of 50 % flowering in all three trials except for the DOS-4. Plant height had a negative and non-significant correlation with grain yield in all the trails. The pooled analysis of Amylose content at DOS-1 and DOS-3 revealed that nine genotypes had low amylose content (24 %). The pooled analysis of ASV at DOS-1 and DOS-3 revealed that ten genotypes had ASV score between 1-2, 17 genotypes had ASV score between 2-3, 17 genotypes has ASV score between 4-5 and 10 genotypes had ASV score between 6-7. Maximum positive correlation with grain yield has been showed by number of tiller per plant in all the four trials. In DOS-1 and DOS-4, length/breadth ratio and ASV, whereas in DOS-2 and DOS-3 number of tillers per plant and 1000 grain weight showed highest direct effect on yield per plant. Trait linked SSR markers used had showed considerable polymorphism among the genotypes. The gene specific primers for heading date (Hd3A), semi-dwarf (sd1) and fragrance (badh2) also explained variation among the genotypes. Genotypes KRS-20, KRS 37, KRS-15 and KRS-16 can be exploited in breeding programme to obtain high yield genotypes as these genotypes showed high per se performance for yield per plant and number of tillers per plant under all four date of sowing.Institutional PublicationsItem Open Access BAU - At A Glance(BAU, Sabour, 2017-07) BAUInstitutional PublicationsItem Open Access BAU Achievements 2015-16 to 2017-18(BAU, Sabour, 2018-11) BAUItem Open Access BAU Annual Report(DEE, BAU, Sabour, 2014) Patel, V.B.; Mahdi, S.S.; Anil; Beura, K., eds.ReportsItem Open Access BAU Annual Report(BAU, Sabour, 2022) BAU; Patil, Shridhar; Shambhavi, Shweta; Goswami, Tarak NathReportsItem Open Access BAU Annual Report(BAU, Sabour, 2022-03) BAU; Beura, Kasturikasen; Aditya; Ganguly, Pritam; Ranjan, Tusar
