ThesisItem Open Access ADOPTION OF BETTER MANAGEMENT PRACTICES BY SHRIMP FARMERS ALONG SOUTH KONKAN COAST OF MAHARASHTRA (Accession No. T06864)(dr. B.S.KKV., Dapoli, 2020-11) NAIK, BHALCHANDRA VILAS; Patil, S. V.Brackishwater shrimp farming is one of the important economic activity in Coastal Maharashtra. However, shrimp farmers are facing a lot of challenges mainly due to disease incidence. Disease is the major threat to shrimp farming. Production, profitability and sustainability in shrimp farming is questionable. It is, therefore very much essential to adopt Better Management Practices in shrimp farming right from the stage of pond preparation till post-harvest activities to achieve sustainability in shrimp farming. Therefore, it is necessary to understand the practices followed by shrimp farmers. Considering this situation, the present study has been undertaken in South Konkan region of Maharashtra to study the knowledge and extent of adoption of Better Management Practices by the shrimp farmers and constraints faced by shrimp farmers in order to achieve sustainable yield in shrimp farming. Information was collected from 59 shrimp farmers by using structured interview schedule. It was found that the maximum 47.97 % shrimp farmers were observed with medium knowledge, whereas 41.40 % of shrimp farmers were with high knowledge and only 10.63 % of shrimp farmers had low knowledge about better management practices in shrimp farming along South Konkan coast of Maharashtra. The most of the shrimp farmers (43.18 %) in the South Konkan region had low adoption while, 37.03 % of shrimp farmers had medium adoption and only 19.79 % of shrimp farmers were found with high adoption about overall better management practices in shrimp farming. The adoption ratio between the knowledge and adoption about better management practices in shrimp farming, along the South Konkan region of Maharashtra was less than one. It can be concluded that all better management practices were less adopted than knowledge. Shrimp price fluctuation (weighted average 39.00), non-availability of crop insurance (weighted average 39.33), and high cost of feed (weighted average 34.67), less Fancy Line Dividers Clip Art Car Pictures | Decorative lines, Free ...availability of good quality seed (weighted average 31.67), prevalence of disease outbreak (weighted average of 31.33) and high cost of seed (weighted average of 31.33) were the major constraint faced by shrimp farmers. It is suggested to address all the identified constraints and immediate preventive measures to be taken to sustain the shrimp culture in South Konkan region, Maharashtra.ThesisItem Open Access ADOPTION OF IPM PRACTICES BY BENEFICIARIES OF CROPSAP(DBSKKV., Dapoli, 2017-05) ROHAM, SUJITKUMAR; Desai, A. N.DEPARTMENT OF EXTENSION EDUCATION COLLEGE OF AGRICULTURE, DAPOLI Title of the Thesis : ‘Adoption of IPM practices by beneficiaries of CROPSAP’ Name of the student : Sujitkumar Dilip Roham Registration Number : 2451 Name of the Research Guide : Prof. A. N. Desai Degree : M. Sc. (Ag) Major Subject : Extension Education Academic Year : 2017 ABSTRACT Present study was conducted in Mahad, Shrivardhan, Mhasala and Poladpur tahsils of Raigad district of Konkan region. The sample was constituted 72 respondents drawn from thirty six villages of four tahsils. The respondents were interviewed with the help of a specially designed schedule. The ex-post-facto research design was used for the present study. The analysis of data revealed that majority of the respondents belonged to ‘middle’ age category and more than thirty per cent of the respondents had ‘secondary’ education having ‘small’ land holdings and ‘medium’ annual income. Majority of the respondents had ‘small’ area under paddy, ‘medium’ extension contact and ‘low’ social participation. Majority of respondents had ‘medium’ level of risk preference and ‘favourable’ attitude towards IPM. Majority of the respondents was belonged to ‘medium’ category of knowledge level. Regarding extent of adoption of IPM practices it was found that majority (41.67 per cent) of the respondents had ‘low’ extent of adoption of integrated pest management practices. Majority of the respondents had not adopted IPM practices. Among the selected variables, age and education had significant association with adoption of IPM practices. However, the association of education was found to be negative. Further, the variable ‘knowledge about IPM’ was found to be positively and significantly associated with adoption. The variables like land holding, annual income, area under paddy, social participation, extension contact, risk preference and attitude towards IPM did not show any significant relation with adoption by respondents. Furthermore, the association, except extension contact and attitude towards IPM, was noticed to have negative effect on the adoption of IPM practices by the respondents. Majority of the respondents expressed problem like heavy and frequent rainfall during season, lack of knowledge about pest, disease and their preventive and curative measures. Regarding suggestions for increasing the effectiveness of the project majority of the respondents (87.50 per cent) expressed guidance for availability of plant protection appliances be given and information regarding pest, disease and their preventive and curative measures be made available. .ThesisItem Open Access ADOPTION OF LIVESTOCK REARING PRACTICES BY THE FARMERS FROM SOUTH KONKAN(dbskkv., Dapoli, 2019) GIMHAVANEKAR, SHUBHAM SHARAD; BORATE, H. V.Present study was conducted in Ratnagiri and Sindhudurg district in South Konkan region of Maharashtra. The sample was constituted 120 livestock owners drawn from two tahsils from Ratnagiri district and two tahsils from Sindhudurg district. The respondents were interviewed with the help of a specially designed schedule. The Ex-post facto research design was used for the present study. The analysis of data revealed that slightly less than two-third (64.16 per cent) of the farmers were in the „middle‟ age category, more than one-third (34.17 per cent) of the farmers were secondary school level of education, more than three-fifth (65.83 per cent) of the farmers had agriculture as their major occupation, more than three-fourth (76.67 per cent) of the respondents had medium annual income, great majority (90.00 per cent) of the livestock owners had medium livestock possession, more than three-fifth (60.83) of the farmers had medium livestock rearing experience. The data again reported that less than one-half (48.00 per cent) of the respondents had marginal land holding, slightly less than one-third (30.00 per cent) of the respondents were in the very poor category of milk production. Management orientation of the farmers indicated that more than one-fourth (32.50 per cent) of the respondents had moderate level of management orientation, less than three-fourth (75.00 per cent) of the respondents had low knowledge regarding livestock rearing practices. It is revealed that half (49.16 per cent) of the livestock owners had very low extent of adoption. As regards to relationship between selected characteristics and adoption of livestock rearing practices revealed that age, education, major occupation, livestock rearing experience and land holding were non significantly related with adoption of livestock rearing practices, whereas annual income, livestock possession, milk production, management orientation and knowledge level were positively and significantly related with the adoption of livestock rearing practices.

G.DEPARTMENT OF EXTENSION EDUCATION COLLEGE OF AGRICULTURE, DAPOLI Title of thesis : Adoption of recommended rice Cultivation practices by the farmers from Palghar district Name of student : Ravindra Shamrao Karangami Regd. No. : 2452 Name of the Research Guide : Prof. P. G. Mehta Degree : M.Sc. (Ag.) Major Subject : Extension Education Year of award of degree : 2017 THESIS ABSTRACT The study was conducted in Wada and Palghar tahsils of Palghar district of Konkan region. The sample was constituted 120 rice growers drawn from twelve villages. The respondents were interviewed with the help of a specially designed schedule. The ex-post facto research design was used for the present study. The analysis of data revealed that majority of the respondents were „middle‟ age, had „secondary‟ education, „marginal‟ area under rice cultivation, „medium‟ rice yield and „medium‟ family size, were having „medium‟ annual income and „medium‟ experience in rice cultivation, had „low‟ extension contact, had „medium‟ input availability , had‟ medium‟ knowledge level. The data regarding adoption level about rice cultivation practices revealed that majority of the respondents had „medium‟ adoption of the selected agricultural technologies of rice crop. The data regarding practice-wise adoption revealed that the respondents had „partially‟ adopted high yielding variety, „use of wooden plough for puddling‟,„ application of fertilizer dose of 100 kg N, 50 kg P and 50 K/ha., „use of Vaibhav sickle‟, Application of insecticides such as Quinolphos, Monochrotophos and Phorate , Application of 3 gm thirum / kg seed‟, for control blast. The „fully‟ adopted practices were „Maintain water depth of 2-5 cm for period of 1 month after transplanting‟, „For small seeded varieties recommended seed rate is 35-40 kg/ha‟. The association between profile of rice growers and their adoption namely, area under rice cultivation, rice yield, annual income, experience of rice cultivation, input availability and knowledge level about rice technology and their extent of adoption of selected agricultural technologies was significant. However, the association of age, education, family size and extension contact with extent of adoption of selected agricultural technologies was non-significant. The major constraints faced by farmers in adoption of selected agricultural technologies of rice crop were shortage of labourers, unavailability of fertilizer at proper time and lower market price of produce, respectively.ThesisItem Open Access ADVANCED EVALUATION OF LOCAL CHILLI (Capsicum annuum L.)

V.Two years research experiment was conducted during Kharif season of 2015 and 2016 to investigate the, “Agronomic assessment of different rice hybrids for sustainable production through agronomic manipulation under high rainfall conditions of Konkan” at Agronomy Farm, College of Agriculture, Dapoli, Dist. Ratnagiri (M.S.). The soil of the experimental plot was clay loam in texture, moderately acidic in reaction, high in organic carbon content. It was medium in available nitrogen, low in available phosphorus and fairly high in available potassium during the both years of experimentation. The field experiment was laid out in split-split plot design comprising 48 treatment combinations replicated thrice. Main plot treatment consisted of four sowing times viz., 23rd meteorological week (4th to 10th June) (S1), 25th meteorological week (18th to 24th June) (S2), 214 27th meteorological week (2nd to 8th July) (S3) and 29th meteorological week (16th to 22th July) (S4). The sub plot treatment consisted of four rice hybrids i.e. Sahyadri (H1), Sahyadri 3 (H2), Suruchi 5401 (H3) and PA 6444 (H4) while, sub-sub plot treatment comprised of three age of seedling, viz., 15 days old seedling (A1), 30 days old seedling (A2) and 45 days old seedling (A3). During the course of present investigation, periodical growth observations, yield contributing characters and yield were recorded to evaluate the treatment effects. The concentration of nitrogen, phosphorus and potassium and its uptake by the rice hybrids was studied. The effect of agroclimatic indices on physiological stages of different rice hybrid was studied. Economics of the treatment combinations was also worked out. The experimental results revealed that rice crop sown in 23rd meteorological week (4th to 10th June) recorded significantly higher growth as well as yield attributes resulting into significantly higher grain and straw yield over the rice hybrids sown in 25th meteorological week (18th to 24th June), 27th meteorological week (2nd to 8th July) and 29th meteorological week (16th to 22nd July). The quality parameters protein content in grain and straw were significantly more under sowing in 23rd meteorological week. However, significantly higher values of N, P and K uptake recorded with rice sown in 23rd meteorological week (4th to 10th June) than rest of sowing times. The available status of nitrogen, phosphorus and potassium after harvest of experimental crop was significantly higher in sowing 29th meteorological week (16th to 22nd July) compared to other sowing times. The rice hybrids sown in 23rd meteorological week recorded highest gross monetary returns of ₹ 1,48,632, ₹ 1,29,842 and ₹ 1,39,237 ha-1, net monetary returns ₹ 53,030, ₹ 37,372 and ₹ 45,201 ha-1 and benefit to cost ratio of 1.55, 1.40 and 1.48 during the years 2015, 2016 and pooled mean respectively. 215 Among the rice hybrids Sahyadri 3 found to be significantly superior for all the growth parameters and most of the yield attributing characters than rest of hybrids except PA 6444 under the investigation. The grain yield, straw yield and quality parameters were significantly enhanced and recorded higher values under the hybrids Sahyadri 3 than rest of hybrids and the hybrid PA 6444 was found to be at par with Sahyadri 3 during both the years. The highest values of N,P,K content and uptake of nitrogen, phosphorus and potassium were noticed under the hybrid Sahyadri 3. Similarly, the values of available nitrogen, phosphorus and potassium were significantly higher under the hybrid Suruchi 5401 (H3) over rest of hybrids during the year 2015 as well as 2016. Significantly the highest gross monitory returns of ₹ 1,12,564, ₹ 96,389 and ₹ 1,04,477 ha-1, net monitory returns of ₹ 26,421, ₹ 12,923 and ₹ 19,672 ha-1 and B:C ratios of 1.27, 1.12 and 1.19 registered under the hybrids Sahyadri 3 during both years of experimentation and in the pooled mean, respectively. The transplanting of rice hybrids 15 days old seedling (A1) recorded the higher growth attributes which were significantly higher as compared to the rest of the age of seedling. Yield attributing characters were also significantly higher under 15 days old seedling as compared to all other age of seedling. The grain yield, straw yield and quality parameters were significantly enhanced and recorded higher values under the 15 day old seedling than over 30 and 45 days old seedling during both the years. The highest values of N,P,K content and uptake of nitrogen, phosphorus and potassium were noticed under the 15 days old seedling. The values of available nitrogen, phosphorus and potassium content of soil after harvest of crop were higher in 45 days old seedling than other age of seedlings. Maximum gross returns of ₹ 1,16,281, ₹ 1,01,157 and ₹ 1,08,719 ha-1 and net return ₹ 27,322, ₹ 14,692 and ₹ 21,007 ha-1 and B: C ratios of 1.28, 1.14 and 1.21 were obtained when crop was 216 transplanted with 15 days old seedling during year 2015, 2016 and in case of pooled mean respectively. All the growth parametters, yield attributes, yield, quality and uptake were significant higher when hybrid rice Sahyadri 3 was sown in 23rd meteorological week (4th to 10th June) and transplanted with 15 days old seedling. In respect of economics of different treatment combinations the treatment combination of crop sown during 23rd meteorological week with 15 days old seedling along Sahyadri 3 hybrid (S1H2A1) recorded maximum values of gross returns (₹ 1,60,647, ₹ 1,45,482 and ₹ 1,53,065 ha-1) net returns were are (₹ 65, 311, ₹ 52,673 and ₹ 58,992) and B: C ratio (1.68, 1.57 and 1.62) during the year 2015, 2016 and in mean, respectively followed by treatment combination of S1H4A1.ThesisItem Open Access AGRONOMIC ASSESSMENT OF DIFFERENT RICE HYBRIDS FOR SUSTAINABLE PRODUCTION THROUGH AGRONOMIC MANIPULATION UNDER HIGH RAINFALL CONDITIONS OF KONKAN (Accession No. T06213)(DBSKKV DAPOLI, 2017-05-30) BAHURE, GANESH KAPURCHAD; Mahadkar, U.

Year of Award of Degree : 2017 ABSTRACT The field experiment was conducted during rabi season of 2016 to investigate the, “Agronomic assessment of zero tilled cowpea (Vignaunguiculata L.) grown with various inputs under Konkan condition.” was conducted at Agronomy Farm, College of Agriculture, Dapoli, Dist. Ratnagiri (M.S.). The experiment was laid out in randomized block design. There were eight treatments which were replicated thrice. The treatments mainly comprised of Absolute control (T1), Weed control (T2), Weed control + RDF (T3), Weed control + RDF + Bio-fertilizers (T4), Weed control + RDF + Bio-fertilizers + Micronutrients (T5), Weed control + RDF + Bio-fertilizers + Micronutrients + Plant protection (T6), Weed control + RDF + Bio-fertilizers + Micronutrients + Plant protection + Paclobutrazol (T7), Weed control + RDF + Bio-fertilizers + Micronutrients + Plant protection + Paclobutrazol + One irrigation (T8). The gross plot size was 6.0 m x 4.5m and net plot size was 4.8m x 3.9m, respectively. The soil of the experimental plot was sandy clay loam in texture, acidic in pH and medium in organic carbon content. It was low in available nitrogen, medium in available phosphorus and available potassium. During the course of present investigation, periodical growth observations, weed study, nodule study, yield attributing characters and yield, soil moisture study were recorded to evaluate the treatment effects also quality and uptake of nutrients by the cowpea were estimated. The experimental results revealed that, treatment Weed control + RDF + Bio-fertilizers + Micronutrients + Plant protection + Paclobutrazol + One irrigation (T8) found significantly superior for all the growth parameters, yield attributing characters, protein content and grain and straw yield followed by treatment T7. However both the treatments remained statistically at par with each other, but found significantly superior over rest of the treatments. Similarly, treatment T6 which was followed by treatments T5, T4, T3, T2 in that descending order. The significantly lowest grain and straw yield was recorded by treatment T1(Absolute control) where no any input was given to crop (T1). Increase in grain yield due to treatments T2, T3, T4, T5, T6, T7 and T8 over treatments T1 was to the tune of 48.44, 64.20, 67.27, 71.09, 76.43, 76.84 and 82.26 per cent, respectively. Assessment of impact of different inputs indicated that, reduction in the yield of rice due to various inputs was to the tune of (16.67 %) due to weed control, (15.14 %) due to RDF, (4.66 %) due to bio-fertilizers, (7.17 %) due to multinutrient solution, (13.89 %) due to plant protection, (1.34 %) due to paclobutrazol and (23.39 %) due to one irrigation. The mean weed density was found to be statistically at all the stages of crop growth. At harvest weed density was recorded significantly lowest in all treatment plots and which were at par except T8. The highest weed density was observed in absolute control plot. The number of effective nodules was recorded significantly highest in T8 than rest of the treatments and the lowest was recorded by T1 (absolute control). Significantly higher values of protein, N, P, and K in grain and stover and total uptake by cowpea was significantly more in T8 over rest of the treatments. Also the soil moisture per cent was significantly highest in T8 than the remaining treatments. In respect of economics, it was observed that the treatment (T8) Weed control + RDF + Bio-fertilizers + Micronutrients + Plant protection + Paclobutrazol + One irrigation has given highest net returns (Rs. 21621.25 ha-1) and B:C ratio (1.79).ThesisItem Open Access AN ECONOMIC ANALYSIS OF SURANGI (Mammea suriga) IN SINDHUDURG DISTRICT (MAHARASHTRA)(Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, 2023-12-21) SAWANT MANTHAN SURESH; Naik V. G.; Bhosale S. S.; Sawant P. A.; Kulkarni S. M.The present study was mainly based on the cost, returns and profitability of Surangi cultivation in Sindhudurg district of Maharashtra. Data were collected from ninety surangi growers for calculating cost and returns whereas primary data from twenty respondents were considered for calculation of establishment cost. Farmers were categorized into small (1-13 trees), medium (14-23), and large (above 24 trees) groups based on number of trees owned by them. Utilizing standard cost concepts, the study aimed to calculate cost return and profitability in surangi cultivation. It was observed that at overall level total cost incurred in surangi cultivation was Rs. 86032.82/ha and total returns were Rs.202902.80/ha. Per quintal cost and productivity for surangi at overall level was Rs. 16583.02 and 5.16 quintal respectively. The benefit cost ratio at overall level was found to be 2.37 which indicates that the Surangi cultivation is profitable.ThesisItem Open Access ANALYSIS OF GENETIC DIVERSITY IN RETENTION OF QUALITY TRAITS OF RICE UNDER KONKAN COASTAL CONDITIONS (Oryza sativa L.)(Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli., 2021-06-30) PARDESHI, PRAJWAL PRADEEPSINGH; Kunkerkar, R. L.; DESAI, S.S.; Bedse, T. J.; Mane, A. V.The present investigation entitled, “Analysis of genetic diversity in retention of quality traits of rice under konkan coastal conditions (Oryza sativa. L) was undertaken to asses genetic variability, correlation, path analysis and genetic diversity in 24 genotypes of rice in Randomized Block Design with three replications at Educational and Research farm, Regional Agricultural Research Station, Karjat, Dist.Raigad, Maharashtra during kharif 2020. The analysis of variance revealed significant variation among the genotypes for all the characters studied. The maximum range of variation was observed for the characters, Number of filled spikelets per per panicle, Number of spikelets per panicle, Water uptake, Plant height, Gel consistency, Days to maturity and Days to 50% flowering. Higher GCV, PCV, heritability and genetic advance as per cent mean were recorded for Test weight, Number of filled spikelets per panicle, Grain yield per plant, Straw yield per plant and Number of filled spikelets per panicle, indicating that simple selection could be practiced for improving these traits. Genotype Karjat-3 demonstrate the maximum Grain yield per plant among all the genotypes. High genotypic coefficient of variation was observed for Number of spikelets per panicle, Test weight, Number of filled spikelets per panicle, Grain yield per plant, Amylose content, L:B ratio, Straw yield per plant, Days to maturity, Gel consistency, Days to 50% flowering and Spikelet fertility. These traits also possess high heritability with high genetic advance hence the selection for these traits was effective. Association analysis indicated that there was positive correlation among Grain yield per plant with Straw yield per plant, Grain breadth and Harvest index while, the Test weight also showed highest highly significant positive correlation with Grain breadth followed by Grain yield per plant, Straw yield per plant and Volume expansion ratio. Test weight had significant positive correlation with Milling percentage followed by Hulling percentage and Harvest index. Selection for these traits can be effectively improve Grain yield. Among the yield components, Genotypic and phenotypic path coefficient analysis showed that Straw yield per plant, Test weight, Grain breadth Harvest Index and Panicle length had the highest positive direct effect on Grain yield per plant where as Grain length and Elongation ratio also found to positively significant for yield. Among these characters, Number of productive tillers per plant possessed both positive association and high direct effects. Hence, selection for this character could bring improvement in yield and yield components. The 24 genotypes were grouped into 5 different clusters on the basis of magnitude of D² values evaluated by Mahalanobis D² analysis. The inter–cluster distance was high between cluster IV and Cluster V, there by indicated wide range of variation among the clusters formed. Hence, the genotypes underlying in these clusters could be selected for breeding programme to obtain potential sergeants. Genotypes OR(CZ)-64, R 2054-147-2-104-1, CR 3663-261- 8-4, R1915-115-1-88-1 and JDP-S-38 was found to be aromatic rice with other desirable trait such as higher Number of tillers per plant and Straw yield per plant. These genotypes can be utilized in breeding programmes in future.ThesisItem Open Access ANALYSIS OF GENETIC VARIABILITY AMONG GERMPLASM OF FINGER MILLET BY USING ISSR MARKER (Accession No. T06030)(DBSKKV., Dapoli, 2016-05) Mr. KELKAR, VIPUL; Bhave, Dr. S.G.PLANT BIOTECHNOLOGY CENTRE COLLEGE OF AGRICULTURE, DAPOLI DR.

Title of Thesis : Analysis of genetic variability among germplasm of finger millet by using ISSR marker. Academic Year : 2014-2016 ABSTRACT The molecular marker technology has a great potential for assessing genetic variability and relationship among the selected germplasms. In the present study forty germplasm of finger millet showing distinct morphological differences were screened using 15 ISSR markers. The DNA was extracted from the green leaf samples collected from 15 days old seedlings of finger millet from 40 gremplasms by rapid DNA extraction method. The combination of extraction buffer used was 200 mM Tris-HCl having pH 8.0, 25 mM EDTA, 250 mM NaCl which showed clear and specific banding pattern when subjected to PCR. Optimum concentration of each component in master mix was used for further ISSR analysis. In which 10 mM (1μl) dNTPs concentration and Taq polymerase 3 U/μl (0.5 μl) gave better amplification. The annealing temperature ranging from 40.40C to 56.70C for 1 minute yielded good results. The finger millet DNA showed better amplification with 15 ISSR primers studied. A total of 1876 bands were amplified and out of which 1552 were polymorphic which showed 83.32 % polymorphism. The primer UBC-834 showed 29.82 minimum per cent polymorphism while the average bands per primer were 124.8. The ISSR profile generated by each of the primer was analyzed using standard DNA ladder (1353-310bp) and compared with their respective banding pattern. The average size of amplified fragment ranged from 200bp to 1650bp. The primer UBC-872 recorded minimum PIC value 0.20, whereas primer UBC-841 gave maximum PIC value 0.88 and average polymorphic information content is 0.70 among the all 40 germplasms. It indicates that 115 ISSR markers have a great potential to show the polymorphism among the finger millet germplasms. The data of 40 germplasms of finger millet were used to generate pair-wise matrix based on the Jaccard’s Similarity co-efficient. The genetic distance was calculated on the basis of pooled data and the dendrogram was constructed. The similarity co-efficient ranged from 0.197 (between germplasm Nagali-55 and KMR-204) to 0.679 (between germplasm VR-762 and PR-202) indicating the distinctness and similarities of these germplasm. Cluster analysis was carried out based on UPGMA analysis and it divided 40 germplasms into two main clusters and each having two sub-clusters. The first sub-clusters of first major cluster comprised of 13 genotypes and the second sub-clusters also comprised of 20 genotypes. The first sub-clusters of second major cluster had 1 genotype. While the second sub-clusters of second major cluster consisted of 6 genotypes.ThesisItem Open Access Analysis of one day and extended days rainfall of Konkan region(Department of Agricultural Engineering and Technology, Dr. B.
