ThesisItem Open Access Effect of different source of chromium supplementation on growth performance, blood metabolites and immune status of Murrah buffalo calves.(SARDARVALLABH BHAI PATEL UNIVERSITY OF AGRICULTURE MEERUT 250110, 2019) Kumar, Deepak; Yadav, Dr. S. P.The aim of this study to investigate the effect of different source of chromium supplementation on growth performance, blood metabolites and immune status of Murrah buffalo calves. For this twenty one murrah buffalo calves selected from the LRC at Sardar Vallabhbhai Patel University of Agriculture & Technology Modipuram, Meerut, and divided into three groups, seven in each. The group first was acted as a control. Group second was supplemented with chromium chloride (CrCl3) @ 1.0mg/kg DMI and group third was supplemented with chromium picolinate Cr(C6H4NO2)3 @ 1.0 mg/kg DMI. Blood samples where fortnightly collected for 90 days. Body weight, Body weight gain, Feed consumption, Feed conversion ratio, glucose, H.D.L. cholesterol, total cholesterol, urea, Total immunoglobulin, lymphocyte total leukocyte count (WBC), aspartate aminotransferase (A.S.T.), alanine aminotransferase(A.L.T.) and alkaline phosphatase (ALP) were estimated. Overall average value of body weight was found 95.66±1.79,97.54±1.76and 98.13±1.67 kgin control, T1 and T2, respectively. did not differ significantly among groups. Overall average value of body weight gain was found 4.60±0.20, 5.07±0.22and 5.27±0.20kg in control, T1 and T2 groups, respectively. Overall average value of body weight gain found significantly higher (P<0.05) in T1 and T2 as compared to control. Feed consumption did not differ significantly between the groups. Overall average value of feed consumption was 39.95±0.70, 38.01±0.70 and 38.20±0.67 kg in respective control, T1 and T2 groups. Overall average value of feed conversion ratio was 8.11±0.38, 7.56±0.37and 7.30±0.32in control, T1 and T2 groups, respectively. Overall average value of feed conversion ratio was significantly lower (P<0.05) in treatment group T2 as compared to T1 and control. The blood concentration of urea was observed significant (P<0.01) difference among groups. Average value of urea was significantly (P<0.05) lower in T2 as compared to all other groups. Overall average value of Glucose was observed significant (P<0.01) different among groups.The average value of total cholesterol was significantly (P<0.05) lower in T2 as compared to all other groups. HDL cholesterol level was differed significantly (P<0.01) among groups. The overall average value of lymphocyte concentration was significantly (P<0.05) higher in treatments as compare to control but no significant difference was found between T1 and T2. The value of WBC did not differ significantly (P<0.01) among groups. Total immunoglobin level was observed significant (P<0.01) difference among groups. Overall value of AST was significantly (P<0.05) lower in chromium picolinate supplemented group as compared to chromium chloride supplemented and control group.. The value of ALT was differ significantly (P<0.01) among groups. The value of ALP was differed significantly (P<0.05) either chromium chloride or chromium picolinate supplemented groups.ThesisItem Open Access Influence of irrigation frequency and weed management practices on growth and performance of transplanted rice (Oryza sativa L.)(SARDARVALLABH BHAI PATEL UNIVERSITY OF AGRICULTURE MEERUT 250110, 2019) Kumar, Deepak; Yadav, Dr. K. G.A field experiment was conducted to evaluate the effect of Irrigation frequency and weed management practices on performance of transplanted rice at Crop Research Centre, Chirori of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut (U.P.), during kharif season 2018. The experiment was laid out in Split plot design with three replications. The experiment consisted of three Irrigation frequency viz.; (I1) Irrigation at 2 day interval, (I2) Irrigation at 5 days interval, and (I3) Irrigation at 7 days interval in main plot and four weed management practice viz.: Bispyriback sodium 25 g a.i./ha PoE, Cono weeder (at 25 & 45 DAT), Two hand weeding (at 25 & 45 DAT) and weedy check in sub plot. Pusa basmati-1 was used as test variety. Among the different Irrigation frequencies the application of (I2) Irrigation at 5 days interval recorded significantly better growth parameters i.e. plant height and no. of tillers at the all stages of crop growth. The highest yield attributes, grain yield (45.39 q ha-1) and straw yield (55.59 q ha-1) was recorded with (I2) Irrigation at 5 days interval, closely followed by (I1) Irrigation at 2 days interval. Whereas In case of weed management practices the lowest weed density and biomass was recorded with (I1) Irrigation at 2 days interval at all the growth stages, which was significantly lower than rest of the irrigation treatment. Among the weed management treatments two hand weeding recorded significantly higher growth parameters, yield attributes, grain yield (45.39 q ha-1) and straw yield (55.59 q ha-1) than weedy check. However in reference to weed management practices Bispyribac sodium 25 g a.i./ha also recorded significantly lower weed density and biomass at all the growth stages and higher weed control efficiency than weedy check. Cono weeder was also produced significantly less weed density, dry matter than weedy check. The highest gross return, net return and B: C ratio was obtained with (I2) Irrigation at 5 days interval. Use of cono weeder produced significantly higher gross return, net return and B: C ratio than Bispyribac sodium. The highest B: C ratio was recorded by cono weeder, which was significantly higher than weedy check. Therefore it can be concluded that application of I2Irrigation at 5 days interval with cono weeder was best management option to get higher yield as well as profit from rice.ThesisItem Open Access “Knowledge Gap and Constraints Analysis of Sugarcane Production Technology in Western Uttar Pradesh”(Sardar Vallabhbhi Patel Universiy of Agriculture And Technology Meerut (U.P.), 2015) Kumar, Deepak; Singh, D.K.The present investigation entitled in “Knowledge gap and constraints analysis of sugarcane production technology in Western Uttar Pradesh” was conducted with the help of the specific objectives. The total sample size was 160 for the study. The results of the study depicted that the majority of the respondents (45.63%) belonged to old age group ranging above 55 years. The majority of the (32.50%) of the total respondent are educated up to High School. Maximum (65.00%) respondents were belongs to other backward caste. The majority of respondents (73.75%) were belonged to joint family system and interested for sugarcane cultivation. The maximum (56.25%) respondents of the sugarcane growers were having large size (above 4 members) of the family. The maximum (94.37%) sugarcane growers were having mixed type of house. Majority of respondents (51.25%) belong to marginal and small categories of land holding (2-4ha.) The maximum (88.12%) sugarcane growers have as their main occupation agriculture. All the respondents having mobile phone. Majority of 93.12 % sugarcane growers have cycle. All the respondents having khurpi, fawara, pruning secateurs. Majority of (40.62%) sugarcane growers are using tube well basis irrigation. Maximum (75.00%) respondents are not participating in any organization activity. Majority of (70.63%) respondents are belonging to the income group above Rs. 2 Lakh annual incomes. The majority of (68.13%) of the respondents belong to medium category of socio-economic status. The farmer’s preferred progressive farmer as a top most source of information and agro chemical distributor was secondary source of information and the maximum sugarcane growers were using Newspaper and T.V. as a mass media source of information. The highest percentage of knowledge gap was found under soil treatment (Biological treatments) in sugarcane cultivation. Majority of respondents (61.25%) possess good knowledge of various aspects of sugarcane production technology. Irrigation was the main problem of sugarcane growers in Western zone.
