(A.P.) INDIA, 2019-04) VENKATESWARLU, M; SADASIVA RAO, K(MAJOR); SRINIVAS, M; DEVI PRASAD, VThe present investigation entitled “Studies on efficacy of GnRH and hCG during mid luteal stage of the cycle in repeat breeder Graded Murrah buffaloes (Bubalus bubalis)” was taken up by screening 130 repeat breeder lactating buffaloes to study the causes of repeat breeding. The efficacy of GnRH (Group 1 – 10μg of GnRH 8 hours before AI at observed estrus and Group 2 – 10μg of GnRH 8 hours before AI at observed estrus and 13th day of post insemination) and hCG (Group 3 – 1500 IU of hCG 8 hours before AI at observed estrus and Group 4 – 1500 IU of hCG 8 hours before AI at observed estrus and 13th day of post insemination) protocols for enhancement of conception rates were studied in 60 repeat breeding Graded Murrah buffaloes in comparison with normal cyclical buffaloes as untreated control (Group 5). The causes of repeat breeding in Graded Murrah buffaloes reared under rural climatic condition includes, repeat breeders without any palpable abnormalities in the genital tract, subclinical endometritis and tubal blockage was recorded to be 60, 66, 4 buffaloes and the percentage was 46.15, 50.78, 3.07, respectively among 130 repeat breeder buffaloes examined. White side test and PSP dye test could be effectively used to diagnosis the subclinical endometritis and tubal blockage, respectively. The mean length of estrous cycle in repeat breeders and normal cyclical buffaloes was 21.68±0.39 and 22.60±0.31 days; duration of estrus was 22.10±0.33 and 24.39±0.08 hours; intensity of estrus 13.42±0.37 and 15.4±0.63 points, respectively. There was no significant difference (P<0.05) in length of the estrous cycle, whereas significantly (P<0.05) less in duration of estrus and lower intensity of estrus in repeat breeder buffaloes when compared with that of normal cyclical buffaloes. Repeat breeder Graded Murrah buffaloes exhibited lowered levels of mean haemoglobin (8.61±0.20 gm%), PCV (35.21±0.99 %) when compared to normal cyclic buffaloes. Further, biochemical parameters viz., mean serum glucose (48.26±2.83 mg/dl), calcium (7.21±0.18 mg/dl), phosphorus (4.44±0.12 mg/dl), total protein (6.57±0.09 g/dl) and cholesterol (85.57±1.90 mg/dl) concentration also showed lowered levels in repeat breeder buffaloes when compared to normal cyclical buffaloes. The conception rates of repeat breeding Graded Murrah buffaloes in Group 1, 2, 3, 4 and control group (Group 5) were recorded to be 40.00, 46.67, 53.33, 66.67 and 42.85 per cent, respectively. It was concluded that all the treatments except that of Group 1 could improve the conception in repeat breeder buffaloes compared with that of normal cyclical buffaloes. However, hCG treatment groups revealed higher per cent of conception rates (53.33 and 66.67%) when compared with that of GnRH treatment groups (40.00 and 46.67%). The human chorionic gonadotropin administered at observed estrus and on 13th day post insemination could effectively improve the conception rates in repeat breeding Graded Murrah buffaloes.ThesisItem Open Access A STUDY ON TECHNOLOGICAL GAP IN ADOPTION OF IMPROVED TECHNOLOGY OF BETELVINE PRODUCTION IN GUNTUR DISTRICT OF ANDHRA PRADESH(PROFESSOR JAYASHANKAR TELANGANA STATE AGRICULTURAL UNIVERSITY. HYDERABAD, 1992) VENKATESWARLU, M; SATYANARAYANA, CHBetelvine is an important horticultural cum commercial crop grown in India in an area of 40,000 hectares. It occupies about 2,626 hectares in Andhra Pradesh. In recent years betelvine cultivators have been facing many technical problems and not getting yields upto potential level. This was mostly due to the fact that betelvine is being mostly grown in a tr ditonal way by the majority of farmers, but success of betelvine cultivation depends on the knowledge and adoption of recommended package of practices. On the other hand, a large part of gains from new farming technologies are still remaining unrealised due to many constraints. These constraints in turn handicap the farmers to exploit the potential of advocated technology in the field, to increase yields. Betelvine farming is an economic activity which involves knowledge, skills and favourable attitude in applying the technology for higher production. Duly keeping in view the problems of betelvine cultivation, this study was taken, to study the knowledge, adoption, technological gap in adoption and yields of betelvine cultivators and constraints in adoption of improved technology of betel vine production. An ex-post facto research design was adopted for the study. Guntur district of Andhra Pradesh was purposively selected. A total of nine villages were selected at random from three selected mandals and one hundred and twenty respondents were selected based on proportionate random sampling. A pre-tested interview schedule with suitable measurement devices of all variables was used for collection of data. The data thus collected was coded and analysed. Majority of the respondents belonged to middle age group ard had education upto primary school level with small landholdings, had medium extension contact, mass media exposure and information seeking behaviour, also had medium social participation, urban contact and scientific orientation with medium income. Majority of the respondents had medium· level of knowledge on recommended package of practices of betelvine. Item analysis revealed that majority of the respondents had no knowledge on the practices like selection of soils, application of manures and fertilisers, packing of leaves and plant protection measures. Majority of the farmers were medium adopters of recommended package of practices of b~telvine. Item analysis revealed that the practices like soil testing, application of manures and fertilisers·, improved methods of packing of leaves and control methods for wilt disease were not adopted by the majority of the farmers. It refers that these practices have maximum technological gap in adoption. The study also revealed that majority of the betelvine cultivators getting average yields. Correlation analysis of independent variables with dependent variables i.e., knowledge, adoption, technological gap and yield indicated that education, extension contact, mass media exposure, information seeking behaviour, social participation, urban contact and scientific orientation had a positive and significant relationship. Whereas, age was negatively significant. On the other hand, farm size and income showed non-significant relationship with knowledge, adoption and yields. Technological gap in adoption had shown opposite relationship with independent variables. Majority of the farmers reported that unawareness of the practice, lack of technical guidance, high cost of labour, unavailability of labour in time, untimely rains and unfavourable weather conditions as constraints in adoption of recommended practices of betelvine. Farmers had also given suggestions to increase the yields of betelvine.
