The present investigation was carried out during Kharif seasons of year 2013-14 and 2014-15 at the Instructional Dairy Farm of G.B. Pant University of Agriculture and Technology, Pantnagar. The experimental material was developed by mating five male sterile lines as tester parents of sorghum with eight lines in line x tester mating design. The field experiment with 55 treatments including 40 F1s, 5 CMS lines as testers, 8 pollinator lines as lines and two standard checks was planted in randomized block design with three replications during both years in kharif seasons. Among pollinators, 11A2 and M35-1 performed best with all testers. For green fodder yield, most of the crosses exhibited singnificant and positive values for batter parent and mid parent heterosis while singnificant and positive standard parent heterosis was recorded only for one cross i.e. 11A2 x UPC2 (16.34). Among all crosses, 11A2 x UPC2 performed best for most of the characters and can be recommended as potential parental combination for further testing for varietal improvement of sorghum.

An experiment consisting of four phosphorus levels (0, 40, 60 and 80 kg/ha P2O5) and five zinc levels (0, 10, 20, 30 and 40 kg/ha ZnSO4) was laid out in randomized block design in factorial mode to find out the effect on yield and quality of fodder cowpea [Vigna Unguiculata (L.)Walp.]. Growth parameters viz. plant height, number of leaves, number of branches, leaf length, leaf width and leaf stem ratio were improved with the application of 60 kg/ha P2O5 and 20 kg/ha ZnSO4. Application of 60 kg/ha phosphorus recorded 27.64 t/ha yield, which was 7.50 and 55.6 % higher than 40 kg/ha and no phosphorus application, respectively. Application of zinc in the form of ZnSO4 @ 20 kg/ha increased significantly the green fodder yield (25.89 t/ha). Interaction effect of phosphorus and zinc application was found significant with respect to green fodder, dry matter yield and nutrient uptake. Yield, phosphorus and zinc uptake in cowpea fodder were showing declining trend at combination of application rate more than 60 kg/ha P2O5 and 20 kg/ha ZnSO4.

Field experiments were conducted at Maize Research Station, Vagarai, Palani Taluk, Tamilnadu during rabi 2018-19 and 2019-20 to find out the influence of detopping on green fodder, grain yield and economics of rainfed maize (Zea mays L.). The experiments were laid out in a factorial randomized block design with three stages and three heights of detopping. Three stages of detopping viz., D1-10 days after 50% silking, D2 -20 days after 50% silking and D3-30 days after 50% silking were tested with three heights of detopping viz., L1 - detopping tassel + 2 leaves, L2 - detopping tassel + 4 leaves and L3 - detopping tassel + 6 leaves with a control (No detopping) replicated thrice. The results of the experiments revealed that detopping 10 days after 50% silking with tassel + 6 leaves recorded higher green fodder yield Regarding grain yield, among the days of detopping, detopping 30 days after 50% silking and detopping 20 days after 50% silking recorded higher yield which were comparable with control (no detopping) (6460 kg / ha). Among the number of leaves, detopping tassel + two leaves recorded higher yield followed by tassel + 4 leaves and both were comparable. Among the treatment combinations, higher grain yield was recorded under detopping 20 days after 50% silking with tassel + 4 leaves followed by detopping 30 days after 50% silking with tassel + 4 leaves and detopping 30 days after 50% silking with tassel + 2 leaves. Regarding economics, higher net return and BC ratio were recorded under the treatment combination of detopping 20 days after 50% silking with tassel + 4 leaves followed by control and detopping 30 days after 50% silking with tassel + 4 leaves.

Background: Soils of North-Western Indo-Gangetic plains (IGP) are deficient in zinc content which may lead to lower forage yield of cowpea. Henceforth, the adequate supply of zinc either through soil or foliar spray and selection of suitable cultivar of cowpea could enhance the fodder productivity.Methods: A field experiment was laid out in factorial randomized block design during Kharif season, 2019 to assess the effect of different zinc management practices (control; 10 kg ZnSO4; 20 kg ZnSO4; 0.5% ZnSO4 foliar spray at 20 DAS; 0.5% ZnSO4 foliar spray at 20 and 40 DAS) on productivity and profitability of cowpea cultivars (C-152; MFC-08-14; MFC-09-1) and post-harvest fertility status of soil.Result: Cowpea cv. C-152 showed the highest growth attributes, green fodder yield, nutrient content as well as uptake and net returns. Among different zinc management practices, the application of 20 kg ZnSO4 as basal application or 0.5% ZnSO4 foliar spray at 20 and 40 DAS recorded significantly highest growth, green fodder yield, nutrient content as well as uptake and net returns. Significantly highest soil OC, available N, K and Zn were also noted under these treatments. It is inferred that cowpea cv. C-152 and application of either 20 kg ZnSO4 as basal or 0.5% ZnSO4 as foliar spray at 20 and 40 DAS were found the most productive and profitable approach and sustained the soil fertility status.

Weed Control Efficiency

Background: Time of pre-emergence herbicide application is an important factor that decides the efficiency of herbicide. If the pre-emergence herbicide is not applied at appropriate time, it may cause ineffective weed control or toxicity to crops. With this background, a field experiment was conducted at TNAU, Madurai to optimize the time of pre-emergence herbicides namely pendimethalin and oxyfluorfen application for effective weed management in irrigated blackgram. Methods: The experiment was laid out in randomized block design with three replication. Treatments were application of pendimethalin at 0.75 kg ha-1 and oxyfluorfen at 0.2 kg ha-1 on 1, 2, 3, 4 days after sowing, weed free check and unweeded check. Result: Results of the study revealed that oxyfluorfen gave maximum weed control efficiency as compared to pendimethalin, but toxicity to the crop was observed when oxyfluorfen was sprayed after 2 days of sowing. Yield and economics were achieved higher with application of 0.75 kg ha-1 of pendimethalin at 2 DAS, which was on par with application of 0.2 kg ha-1 of oxyfluorfen at 1 DAS due to lesser toxicity. Application of 0.75 kg ha-1 of pendimethalin and 0.2 kg ha-1 of oxyfluorfen didn’t leave any herbicide residue after harvest. Hence, application of 0.75 kg ha-1 of pendimethalin at 2 DAS and 0.2 kg ha-1 of oxyfluorfen at 1 DAS can be recommended for effective weed management in irrigated balckgram.

ABSTRACT: The objective of this study was to evaluate the plant and fruit characteristics in advanced lines of Jalapeño pepper for mechanical harvesting. Thus, two experiments were carried out in the field. Experiment I (2015) was conducted as a randomized block design (three replications and eight plants per plot) and Experiment II (2016) in a completely randomized design (five replications and ten plants per plot). In 2015, lines CNPH 30,112, CNPH 30,118, CNPH 30,147, CNPH 30,159, CNPH 30,183, and CNPH 30,245 were evaluated, together with the control ‘BRS Sarakura’. Significant differences were detected for fruit and plant characteristics (P<0.05). Lines CNPH 30,118, CNPH 30,147, CNPH 30,159, and CNPH 30,245 were selected based on plant height and height of the first bifurcation, earliness, and yield. They were evaluated again in 2016, together with ‘BRS Sarakura’ and ‘Jalapeño Plus F1’ as controls. In 2016, CNPH 30,159 and CNPH 30,118 were selected due to their potential for mechanical harvesting. They were evaluated for height of the first bifurcation (>10cm), large fruits (11 cm x 4 cm), high pulp firmness (11 N), wall thickness (about 5mm), and content of capsaicinoid substances (>50,000 SHU). Selected lines are undergoing additional field evaluation for mechanical harvesting with the Etgar Moses 1010 pepper harvester.

A field experiment was conducted during rabi season of 2011-12 on heavy black soil to study the effect of integrated nutrient management on growth and yield of baby corn. The treatments comprising all possible combinations of five levels of nitrogen (chemical and vermicompost fertilizer) with and without bio-fertilizer (Azotobacter and PSB) were laid out in randomized block design with three replications. These were significantly higher with application of 100% RDN from chemical fertilizer with bio-fertilizer over 100% RDN from vermicompost. The cob and fodder yields significantly differed with different integrated nutrient management treatment. Significantly the higher growth and yield attributes yield and fodder yield were recorded with the application of 100% RDF from chemical fertilizer with bio-fertilizer. Application of 100% RDN from chemical fertilizer with biofertilizer was recorded higher net returns over 100% RDN from vermicompost (Rs. 220775/ha) and BCR (12.54).
