ThesisItem Open Access Variability of leaf blight pathogen of Linum usitatissimum L.”(Department of Plant Pathology, BAU, Sabour, 2017-09) Kumari, Sujata; Srinivasaraghavan, A.To study the variability of the Alternaria blight pathogen, a total of 19 isolates including four of ALTERNARIA LINICOLA and 15 of ALTERNARIA LINI were collected from different agro-ecological zones of Bihar. All the isolates were subjected morpho-physiological, cultural and pathogenic variability studies. A good amount of morphological variability was found among the different isolates. In A. LINICOLA, colony colour was found to be greyish black to grey with white and smooth margin. The maximum spore size was found in ALC-2 (40.2-44.6 X 9.5-10µ m) with a septation 9-12 horizontal and 3-4 vertical septa. The days taken to sporulation was found maximum in ALC-1 (14 days) and minimum in ALC-4 (10days). Similarly in A. LINI a colony colour of white or whitish grey to greyish black with whitish grey to white with smooth margin was recorded . Maximum spore size was found in ALN-14 (21.4-23.6 X 12.3-12.9µm) with a septation of (5-7 X 2-3). The days taken to sporulation was found maximum in ALN-1, 6 & 15 (16 days) and minimum in ALN-3 & 12 (11days). Maximum growth on potato dextrose agar (PDA) was achieved after two weeks of incubation. The mean mycelial dry weight of six isolates were measured at different temperature conditions revealed that, 250 C was the most favourable condition for production mycelium (57.2mg). Among the different isolates, ALN 15 (44.2mg) was found to be performing better at all the temperatures. Interestingly, the A. LINICOLA isolates were found better at lower temperatures (150C). Similarly the Relative Humidity (RH) of 90 per cent was found better for all the isolates tested. The maximum radial growth was found in ALN-4 (37.3) at 80 per cent RH. The detached leaf and pod techniques followed to test the pathogenic variability were successfully able to differentiate the isolates. The per cent maximum incidence of on leaf was found in ALN-3 (97.2) and ALN-4 at par with ALN-7 (91.7). The least was recorded on ALC-12 (47.2). The lesion diameter was found maximum in ALN-3 and 4 (7.4mm) followed by ALN-13 (6.80) and the least was found to be in ALN-6 (4.57mm). On pods, highest disease at end of 72 hpi was found in ALC-3 (66.7 %) being at par with other A. LINICOLA isolates which indicated that, A. LINICOLA isolates were more aggressive compared to A. LINI and vice-versa on leaves.ThesisItem Open Access Nitrogen and weed management in direct-seeded rice (Oryza sativa L.)(Department of Agronomy, BAU, Sabour, 2017-09) Kumar, Chandan; Tyagi, ShashankA field experiment entitled “Nitrogen and weed management in direct-seeded rice (Oryza sativa L.)’’ was conducted during kharif 2015 at Research Farm, Department of Agronomy, Bihar Agricultural University, Sabour, Bhagalpur, Bihar. Treatments were laid out in split plot design replicated thrice. Three nitrogen splitting, 1/3 at sowing + 1/3 at tillering + 1/3 at panicle initiation (N1), 1/4 at 20 days after sowing + 1/2 at tillering + 1/4 at panicle initiation (N2), 1/3 at 20 days after sowing + 1/3 at tillering + 1/3 at panicle initiation (N3) were kept in main plot and each main plot is sub-divided in five sub-plots having five weed management treatments,viz., weedy (W1), weed free (Three hand weeding at 15, 30 and 45 DAS ) (W2), pendimethalin 1.0 kg a.i. ha-1 PE fb one hand weeding at 30 DAS (W3), pendimethalin 1.0 kg a.i. ha-1 PE fb bispyribac sodium @ 25 g a.i. ha-1 POE (W4), pendimethalin 1.0 kg a.i. ha-1 PE fb ethoxysulfuron @ 18.5 g a.i. ha-1 POE (W5). Among different nitrogen splitting methods 1/3 at 20 days after sowing + 1/3 at tillering + 1/3 at panicle initiation (N3) resulted the best expression of growth characters and yield attributes at harvest, which was ultimately reflected highest grain yield (36.6 q ha-1), which exhibited statistical parity with N2 treatment and was found significantly superior over N1 treatment which recorded lowest grain yield (35.3 q ha-1). Lowest weed dry weight, highest weed-control efficiency, minimum N uptake by weeds and maximum net returns were recorded with the splits involving 1/3 at 20 days after sowing + 1/3 at tillering + 1/3 at panicle initiation (N3). Among weed management practices, weed free (Three hand weeding at 15, 30 and 45 DAS) (W2) and pendimethalin 1.0 kg a.i.ha-1 PE fb hand weeding at 30 DAS (W3) were found to be superior in respect of growth characters and yield contributing attributes and final grain yield of rice. The highest N uptake by rice, higher recovery of applied nitrogen, minimum dry weight of weeds, highest weed-control efficiency and minimum depletion of nitrogen by weeds and maximum net returns were recorded with weed free (Three hand weeding at 15, 30 and 45 DAS) (W2) which was at par with pendimethalin 1.0 kg a.i. ha-1 PE fb one hand weeding at 30 DAS (W3). From the results of the present study, it may be concluded that among nitrogen splitting, application of 1/3 N at 20 days after sowing + 1/3 N at tillering + 1/3 N at panicle initiation in direct seeded rice produced higher growth, yield attributes and net return and among weed management practices, weed free (Three hand weeding at 15, 30 and 45 DAS) and pendimethalin @ 1.0 kg a.i. ha-1 PE fb one hand weeding at 30 DAS were found the best & reflecting higher yield of rice and reduced weed density leads to more weed control efficiency and less weed index, however, pendimethalin @ 1.0 kg a.i. ha-1 PE fb ethoxysulfuron @ 18.5 g a.i. ha-1 POE exhibited maximum B:C ratio. However, the results are of one season. Further experimentation is needed to have the right recommendation of time of nitrogen application and weed management practices for direct seeded rice for a particular agro-climatic situation.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 Selection of parents for yield improvement in Linseed (Linum usitatissimum L.) under irrigated condition(Department of Plant Breeding and Genetics, BAU, Sabour, 2017-08) Kumari, Shweta; Nirala, R.B.P.Linseed (Linum usitatissimum L.) commonly known as flax having 2n = 30 chromosomes is a self pollinated crop that belongs to the family Linaceae. It is cultivated mainly for its seed oil and its high quality stem fibre. Linseed oil is the richest source of omega-3 fatty acids which has been functionally associated with numerous positive health claims in human and animal. Inspite of all these nutritional value, Linseed is always neglected due to its poor yield and non-availability of improved cultivars which is one of the limiting factors of its popularity. Therefore , a study was undertaken for evaluation of the 31 linseed genotypes collected from AICRP, linseed, Sabour and PC Unit, linseed Kanpur, including two checks, T-397 and Shekhar. The genotypes were grown in randomized complete block design with three replications during Rabi 2015-16 at Bihar Agricultural college farm, BAU, Sabour, Bhagalpur to select parents for yield improvement in linseed. The analysis of variances for design of experiment revealed highly significant differences among the genotypes for all the 20 characters studied. The characters namely, number of primary branches per plant, number of capsules per plant, bud fly infestation, 1000-seed weight, biological yield per plant, seed yield per plant, harvest index, stearic acid and linoleic acid exhibited high GCV, PCV and high heritability coupled with high genetic advance. Correlation studies showed a significant and positive correlation between seed yield per plant and number of capsules per plant, number of seeds per capsule, 1000-seed weight, seed length and biological yield per plant while bud fly infestation was significant and negatively correlated with seed yield per plant. A non significant correlation between oil and fatty acids were found in biochemical study. While, a significant and positive correlation between palmitic acid and stearic acid and negative correlation between stearic and linoleic acid and between oleic acid and linolenic acid were found in present study. Path analysis indicated that bud fly infestation exhibited high and negative direct effect on seed yield per plant. While, number of seeds per capsule and 1000-seed weight showed moderate direct effects on seed yield per plant. Indirect effects of number seeds per capsule, seed length, 1000-seed weight and biological yield per plant on seed yield per plant via bud fly infestation were recorded moderate to high. On the other hand, all the fatty acid namely, stearic acid, oleic acid, linoleic acid and linolenic acid showed high and negative direct effect on oil content except palmitic acid which showed positive and low direct effect. The indirect effect of individual fatty acid via other fatty acids on oil content was recorded moderate to very high. On the basis of D² analysis, 31 genotypes were grouped into 6 divergent clusters. Cluster I was the biggest with 12 genotypes followed by cluster II and cluster V. Inter cluster D2 value was the highest between cluster II and VI followed by V and VI. Molecular diversity analysis was also done with 20 SSR primers. Out of 20 primers, 15 primers were found polymorphic, 3 monomorphic and other two gave non scorable band. The PIC value of SSR primers ranged from 0.1-0.447 with an average of 0.245. However, the similarity coefficient ranged from 0.5 to 0.9. Among the 31 genotypes, the lowest similarity coefficient was observed between GS-202 and Neelum (0.50) followed by the pair EC-1424 and H-40 (0.51) indicating their distant relationship and the highest between Meera and EC-537911 (0.90) indicating presence of a common ancestry. Based on the D2 values, clusters mean and means of the genotypes, nineteen genotypes were selected and their possible cross combinations namely, EC-1424 with BRLS -101, BRLS-102, BRLS-103 for oil & oil quality and EC-1424 with Parvati, EC537911A and Neelum for seed yield and its attributing characters were identified to obtain better segregants in linseed breeding programme.ThesisItem Open Access Techno-economic Analysis of Lentil Production in Mokama Tal of Bihar State(Department of Extension Education, BAU, Sabour, 2017-08) Kumar, Randhir; Panda, Chandan KumarPulses are important sources of protein, high in fiber content and provide ample quantity of vitamins and minerals. Keeping in view large benefits of pulses for human health, the United Nations had proclaimed 2016 as the International Year of Pulses. Bihar is one of the important states in India for pulse production. Amongst the different pulses, lentil is one of the important pulse crops for Bihar. Demand of lentil in Bihar is also high. So, it becomes imperative to study technology and economic aspects of lentil cultivation/production to match the requirement of lentil in India in general and Bihar in particular. There are some socio-economic issues related researches in pulses cultivation in Bihar, however, there are very limited study specifically for lentil cultivation in aforesaid aspect. Mokama Tal area is famous in India for its pulses cultivation. Thus, keeping all this in mind, this research work was coined with the objectives of i)to study the socio-economic profile of selected lentil growers in Mokama Tal; ii)to study the technological gap in lentil production in study area; iii)to identify the factors responsible for changing trend of lentil cultivation area; iv)to estimate the costs and returns of lentil cultivation; and v) to assess the constraints in lentil cultivation. For the present study 120 respondents were selected randomly from Mokama Tal area. From the study it was noted that maximum number of respondents (60.00%) were middle age group, most of them were male and 45.83% respondents belonged to general category. Most of the famers lived in joint family. It was also noted 70.82 % respondents had more than 10 years of farming experiences and 37.50% of them were big farmers. Major sources of information to the farmers were radio, kisan salahkaar, progressive farmers, and kisan diary. Major knowledge gap was noted in case of fertilizer management, land preparation and weed management. It was also noted that area under lentil cultivation is gradually increasing because of good stand of lentil, better response to DAP fertilizers, good market chain and stealing of standing lentil crop is less as compare to other pulses. The most important perceived abioticconstraints in lentil cultivation were soil hardiness after seed sowing and soil cracking. Short sowing period, on availability of credits in time, lack of knowledge on seed treatment, fluctuating prices of lentil,increase in cost of seed, timely availability of labour were some other important constraints as perceived by respondents.ThesisItem Open Access Management of aphid (Lipaphis erysimi using eco-friendly approaches in mustard(Department of Entomology, BAU, Sabour, 2017-08) Kumari, Annu; Vishwakarma, RamanujThe present investigation was carried out at Research Farm of Bihar Agricultural University, Sabour, Bhagalpur, Bihar, India during 2015-16 and 2016-17. Three experiments namely, screening of the germplasms against mustard aphid, L. ERYSIMI efficacy of different botanicals and effect of different border crops on population of mustard aphid have been carried out. Seventy seven germplasms were evaluated against mustard aphid (L. ERYSIMI), and out of them, germplasm IC491089 was found resistant (field tolerant) with aphid population of 21.3 -30.7 aphids/plant. The germplasm IC385703 was highly susceptible against mustard aphid and found to range from 87.0-195.3 aphids/plant. There were 4 germplasms found under resistant category, 3 germplasms under moderately resistant, 54 germplasms under susceptible and 16 germplasms under highly susceptible. About 70% germplasm were susceptible against mustard aphid. The aphid infestation in mustard crop was observed from flowering stage and reached at peak during pod formation stage, afterwards it declined in all the germplasms. Efficacy of 1% leaf extract of neem, calotropis, chrysanthemum, lanata, parthenium and thiamethox am (0.008%) was assessed against mustard aphid under filed conditions during both the years. Among botanicals, lantana leaf extract @ 1% was found best for managing mustard aphid with appreciable yield as compared to other botanicals, while thiamethox am was found at par. The order of the efficacy of botanicals against aphid was lantana > neem > calotropis > parthenium > chrysanthemum. According to yield parameter, the order of botanicals was lantana > neem > parthenium > chrysanthemum > calotropis. Effect of different border crops VIZ. safflower, red giant mustard (RGM), coriander, onion and maize was observed on population of mustard aphid and its natural enemies. Among the border crops, the least number of aphids were in safflower bordered plot with highest yield followed by maize. Further, the number of coccinellid/plant was observed 8.86 times more in safflower bordered plot on last date of observation during first week of March as compared with first date of observation in the last week of January.ThesisItem Open Access Morpho-physiological variability and antagonistic potential of native fluorescent Pseudomonads from Zone 3A of Bihar(Department of Plant Pathology, BAU, Sabour, 2017-07) Gupta, Annu Kumari; ErayyaBiocontrol agents have great demand now-a-days as they are replacing chemical pesticides to a large extent as they are cost effective and eco-friendly. The use of biological control agents as an alternative to fungicides is increasing rapidly in the present day agriculture due to the deleterious effects of chemical pesticides. Fluorescent Pseudomonads, a major constituent of rhizobacteria, encourages the plant growth through their diverse mechanisms. Its name implies, it secretes greenish fluorescent pigment called fluorescein, particularly under condition of low iron availability fluorescent Pseudomonads are one among them which not only enhance the plant growth but also control the fungal pathogens by production of antifungal metabolites. Present investigation was focused towards isolation of fluorescent Pseudomonads from different crop rhizospheres, morpho-physiological characterization and evaluation of antagonistic potential of these isolated fluorescent Pseudomonads against three fungal pathogens viz., Rhizoctonia solani, Sclerotium rolfsii and Fusarium spp. Twenty six fluorescent Pseudomonads were isolated from different crop rhizospheric soils collected from different villages of Bhagalpur and Kishanganj. The isolates were purified on King’s-B medium and confirmed by observing under UV light. Out of twenty six, sixteen isolates were confirmed as fluorescent Pseudomonads. Among sixteen isolates twelve were found producing round to oval shaped colonies and four isolates produced irregular colonies on King’s-B agar medium. Colony colour varied from isolate to isolate viz., slightly yellowish white, green, dull white and whitish green to yellowish. Isolate WHSB produced maximum number of colonies (51.33X10-8/ml) followed by MSSB (28.33 X10-8/ml) on King’s-B medium. Colony size was found maximum (13.33mm) in MRKH followed by TMGH (12.00 mm). Fluorescent Pseudomonads produced different colour pigmentation (light green, dark green, bluish white and bluish green) at lower surface of King’s-B medium. Both the selected isolates, high fluorescent isolate (MSSB) and low fluorescent isolate (WHSB) preferred pH 7.5 for their optimum growth followed by pH 7.0 and 8.0, respectively. The same isolates also preferred the glucose as a carbon source followed by dextrose for their rapid growth. In vitro evaluation studies indicated that isolate BMGH shown maximum antagonism against Rhizoctonia solani with 55.66 per cent inhibition of pathogen over control followed by isolate WHKH (47.16 per cent) and MSKSN (46.22 per cent). Isolate CHGH was found least effective (15.09 per cent) followed by BRKH (16.03 per cent). Against Sclerotium rolfsii, isolate LNSB had maximum antagonism (88.81 per cent) followed by WHKH (79.72 per cent) and isolate BRKH was found least effective (23.78 per cent) followed by CKSB (32.87 per cent). Isolate MZKSN and BRGH were found to have maximum antagonism against Fusarium spp. (58.74 per cent) followed by WHSB (56.65 per cent) and MRKH was found least effective (15.39 per cent) followed by MSKSN (20.29 per cent). The effective isolates screened under in vitro may further tested under field conditions and may used for management of soil-borne fungal plant diseases.ThesisItem Open Access Distribution pattern and life table of stem borer Chilo partellus(Swinhoe) on maize(Department of Entomology, BAU, Sabour, 2017-07) Kumar, Devbrat; Kumari, KiranMaize (Zea mays L.) is a cereal grain, called “queen of cereal”. It is the third important cereal crop in India after rice and wheat with a share of 10 percent in total cereal production, occupying an area of 9.60 million ha with production of 26.0 million tonnes in which Bihar is contributing an area 0.70 million ha and production 2.05 million tonnes.Maize has a loss of 20 percent in yield due to insect damage. It is damaged by a large number of insect pests at different stages of crop growth. Among the insect pests, maize stem borer (ChilopartellusSwinh.) is a key pest causing losses to grain yield, which ranged between 24.3 and 36.3 percent in different agro climatic regions of India (Bhanukiran and Panwar, 2000).Keeping all these in view, the present investigation was aimed to study on “Distribution pattern and life table of stem borer Chilopartellus (Swinhoe) on maize” with the objectives: i.Seasonal Incidence of Chilopartelluson maize,ii. Determination of distribution Pattern of C. Partelluson maize, and iii. Life table study of C. Partelluson maize. The study on seasonal incidence of stem borer, C. partellusand its relationship with abiotic factors during Kharif and Rabi season, 2016-17 revealed that the incidence of stem borer started (1.67 and 2.51 percent dead heart) in the second week of July at 15 days and last week of November at 21 days old crop age, respectively and reached to its peak ( 16.67 and 11.00 percent dead heart) in the last week of August and third week of February at 57 days and 110 days old crop age during the experimentation period, respectively. Afterwards, the incidence of maize stem borer had declined gradually. The correlation studies of dead heart infestation and abiotic factors during Kharif,2016 showed that the maximum temperature was positively non-significantly correlated and minimum temperature and sunshine hours were positively significantly correlated while rainfall and relative humidity were negatively non-significantly correlated with dead heart infestation.Correlation studies for Rabi season, 2016-17 showed that the maximum temperature was positively significantly correlated, minimum temperature and sunshine hours were found to be positively non-significantly correlated while relative humidity was negatively significantly correlated with the dead heart infestation. The egg distribution within plant showed more number of eggs(107±0.55) on first leaf sheath followed by second leaf sheath (75.33±1.72) and least number on basal leaf sheath (47.10±0.55). The total oviposition period was observed to be five days with average fecundity as 220±3.76 per female moth. The distribution pattern of larvae was found in scattered fashion from seedling to initial vegetative phase of the crop while at the age of 22 to 71 days its distribution pattern was found contagious in nature. Life table study revealed that 42 percent mortality of eggs due to unknown factors whereas, 19.54 percent failed to hatch, 37 percent larval mortality was due toparasitization and 16.07 percent died due to unknown factors. Percentage mortality of pupae was 11.76 due to diseases while 15.38 percent failed to emerge into moths. Thus due to effect of biotic and abiotic factors the total mortality (K value) of Chilopartelluswas 0.88.ThesisItem Open Access Effect of sowingdates and fertility levels on growth and yield of Katarni rice(Department of Agonomy, BAU, Sabour, 2017-07) Kumar, Kailash; SushantRice (Oryza sativa L.) is a cereal belongs to the family Poaceae and genus Oryza with chromosome no. = 24. Rice is one of the most important food grains produced and consumed all over the world. Global rice demand is expected to rise 496 mt in 2020 and further increase to 553 mt in 2035. In Bihar, rice is the major food crop which is grown in 3.23 mha with a production of 6.80 mt with productivity 2.11 t/ha during the season 2015-16 (Directorate of Economics and Statistics, G.O.B. 2016-17). The increasing demand for rice grain production has to be achieved by using the efficient sowing dates with an integration of suitable fertility levels to maintain the sustainability in crop production. Being an aromatic rice - determining quality and yield of Katarni rice sowing time is a major factor. It is due to the fact that the chemical compound (2-Acetyl-1-pyrolline) is highly volatile in nature and its amount in final harvested grain depends upon the atmospheric temperature when the plant enters into anthesis stage or bears panicle. Another key factor for the production of aromatic rice is fertilizer. It plays a vital role in food grain production specially nitrogen. As aromatic rice, especially those which are of tall traditional type like “Katarni” are low yielder and excess nitrogen may cause lodging and deterioration of quality due to inverse relationship between nitrogen content and amylose content in grain its proper dose plays a crucial role for realising an optimum yield of Katarni rice. Keeping in view the above facts an experiment entitled “Effect of Sowing Dates and Fertility Levels on Growth and Yield of Katarni Rice’’ is undertaken during the Kharif 2016-17 at Research Farm, of Bihar Agricultural University, Sabour, Bhagalpur, Bihar, India The experiment was laid out in split plot design replicated thrice. Three rice sowing dates, 1stweek of July (D1), 2ndweek of July (D2)and 3rd week of July (D3)were kept in main plot and each main plot is sub-divided in five sub-plots having five fertility levels (kg N: P2O5: K2O ha-1), 40:30:20 (F1), 45:35:25 (F2),50:40:30 (F3), 55:45:35, (F4) and 60:50:40 (F5) Among different sowing dates, the maximum grain (36.06 qha-1)) and straw (69.24 qha-1) yield were recorded on1stweek of July sowing (D1) which were at par with 2nd week of July sowing (D2) but significantly superior over 3rd week of July sowing (D3). Grain and straw yield increased significantly at fertility level (F2) 45:35:25 kg N: P2O5: K2O ha-1. The maximum net return(Rs. 59849 ha-1) was recorded on 1st week of July sowing (D1). Significantly the maximum benefit cost ratio (1.54) was recorded on 1st week of July sowing (D1). Gross return and net return increased significantly at fertility level (F2) 45:35:25 kg N: P2O5: K2O ha-1. Thus the study suggested that for getting higher yield and net returns, among different sowing dates 1st week of July sowing (D1) and among different fertility levels, 45:35:25kg N: P2O5: K2O ha-1(F2) may be a good optionfor cultivation of Katarni rice.
