    (COLLEGE OF AGRICULTURE, UMMEDGANJ, KOTA, 2020-07-16) Danga, Narendra; Yadav, Rajendra Kumar
    field experiment was conducted during kharif season of 2019 at Research Farm, Agricultural Research Station, Ummedganj, Kota to study the “Effect of Integrated Nutrient Management Practices on Soil Health and Yield of Black gram (Vigna mungoL.)”. The soil of the experimental site was clay loam in texture slightly saline in reaction, low in available nitrogen, medium in available phosphorus, high in available potassium and sufficient in micronutrients. The experiment was laid out in factorial randomized block design with three replications. The experiment comprised three fertility levels (75%, 100%, and 125% RDF), two FYM level (control and 5 ton FYM) and three biofertilizers level (Rhizobium, LMn16 and Rhizobium + LMn16) were applied to the variety Mukundra Urad 2. Results revealed that application of 125% RDF was significantly increased the all the growth and yield parameters. The maximum plant height plant-1 (28.5 cm), number of branches plant-1 (12.1), pedicle plant-1 (15.2) and pods plant-1 (21.8) were recorded with theapplication of 125% RDF treatment. Dry matter accumulation (20.3 g), seed yield (900 kg ha-1) and biological yield (4640 kg ha-1) of black gram were significantly influenced with the 125% RDF treatment in comparison to lower fertility levels. The application of 125% RDF was significantly increased the organic carbon (0.46%) and nutrient content viz., N (199.4 kg ha-1), P (22.7 kg ha-1), K (568.7 kg ha-1) and micronutrients viz., Zn, Fe, Mn and Cu in soil as well as seed and straw of black gram. While, soil physical properties remain constant after harvest of black gram with the application of fertility levels. Application of 125% RDF was significantly increased economics of black gram viz., gross return ( 67507 ha-1), net return ( 40686 ha-1) and benefit cost ratio (1.6) followed by lower fertility levels.Application of farm yard manure was significantly increased the growth and yield parameters. The maximum plant height plant-1 (28.1 cm), number of branches plant-1 (12.1), pods plant-1 (21.5) and dry matter accumulation plant-1 (20.3 g) were recorded with theapplication of 5 ton farm yard manure over the control. The nodule count plant-1 at 40 DAS (24.1) and their dry weight plant-1 (43.8 g) were also higher in FYM treated plot. Whereas, the highest seed yield (827 kg ha-1) and biological yield (4345 kg ha-1) of black gram was recorded with the application of 5 ton FYM over control. Effect of FYM on soil organic carbon (0.48%) and nutrient content significantly increased viz., N (197.8 kg ha-1), P (21.2 kg ha-1) and K (553.6 kg ha-1) in soil while, in seed and straw of black gram N, P, K and micronutrients were also significantly increasedresultant, the protein content in seed (20.7%) and protein yield (171 kg ha-1) was significantly enhanced. Further result indicated that application of biofertilizer (Rhizobium+ LMn16) at the time of sowing black gram significantly increased the plant height plant-1 (28.6 cm), number of branches plant-1 (12.3), pedicle plant-1 (14.6), pods plant-1 (21.6), nodule count plant-1 (24.2) and their dry weight (46.7 g). The maximum seed yield (862 kg ha-1), biological yield (4432 kg ha-1), net return (46530 ha-1) and B:C ratio (2.28) were recorded with the inoculation of Rhizobium + LMn16 over sole inoculation of Rhizobium and LMn16. Whereas, organic carbon (0.47%) and nutrient content like nitrogen (197.2 kg ha-1), phosphorus (20.8 kg ha-1), potassium (556 kg ha-1) content in soil as well as seed & straw of black gram likewise N, P, K, Zn, Fe, Mn and Cu were significantly increasedwith the inoculation of Rhizobium + LMn16 followed by sole application of Rhizobium and LMn16. The protein content (20.7) and protein yield (177 kg ha-1) was also found significantly higher under Rhizobium + LMn16 over individual inoculation of Rhizobium and LMn16. Hence, it can be concluded that the application of 125% RDF along with biofertilizer (Rhizobium + LMn16) would be useful to enhance the productivity of black gram. The conjunctive use of inorganic fertilizers and biofertilizers could be suggested for higher yield along with overall betterment.

    EFFECT OF IRRIGATION SCHEDULES AND SOIL AMENDMENTS ON SOIL PHYSICAL CONSTRAINTS, WATER PRODUCTIVITY AND YIELD OF SOYBEAN UNDER VERTISOLS OF SOUTH-EASTERN RAJASTHAN
    (COLLEGE OF AGRICULTURE, UMMEDGANJ, KOTA, 2021-09-13) MEENA, SUNIL KUMAR; Yadav, Rajendra Kumar
    A field experiment was conducted during Kharif season of 2020 at Instructional Farm, Agricultural Research Station, Ummedganj, Kota (Rajasthan) to study the “Effect of Irrigation Schedules and Soil Amendments on Soil Physical Constraints, Water Productivity and Yield of Soybean under Vertisols of South-Eastern Rajasthan”. The experiment was laid out according to Strip Plot Design with three replications. The treatments consisting of three levels of irrigation schedules (0.6, 0.8 and 1.0 IW/CPE ratios) and three soil amendments (Mustered straw, wheat straw and Compost @ 5 t ha-1) were applied to the soybean var. JS20-34 as soil application with uniform application of nitrogen, phosphorus and potassium as per recommended doses. The main findings of investigation are summarized as: The increasing levels of irrigation schedules increased the plant height, dry matter accumulation, number of nodules per plant, number of pods per plant, number of seeds per pod, test weight, seed yield, straw yield and biological yield as well as content and uptake of nitrogen, phosphorus and potassium in seed and straw and gross, net returns and B: C ratio as compared to control. The pH, electrical conductivity, organic carbon, bulk density, particle density, water use efficiency, total applied water and geometric mean diameter was found to be non-significant at harvest stage of crop and available nitrogen (N), phosphorus (P2O5), potassium (K2O) and micronutrients (Zn, Fe, Mn and Cu) content, aggregate stability, Mean weight diameter, water stability aggregate and labile fractions of carbon of soil at harvest stage of crop was increased and soil crack volume decrease significantly with increasing levels of irrigations schedules.The application of soil amendments increased significantly the plant height, dry matter accumulation, number of nodules per plant, number of pods per plant, number of seeds per pod, test weight, seed yield, straw yield and biological yield as well as content and uptake of nitrogen, phosphorus and potassium in seed and straw and gross, net returns and B: C ratio as compared to control. The application of soil amendments enhanced the available nitrogen (N), phosphorus (P2O5), potassium (K2O) and micronutrients (Zn, Fe, Mn and Cu), aggregate stability, Mean weight diameter, water stability aggregate and labile fractions of carbon and decrease soil crack volume. Whereas, the pH, electrical conductivity, organic carbon, bulk density, particle density, water use efficiency and total applied water was found to be non-significant at harvest stage of crop. The significantly highest seed yield, gross returns, net returns and B: C ratio was observed under the treatment I3 (Irrigation schedules @ 1.0 IW/CPE ratio) and S3 (Compost @ 5 t ha-1), respectively. However, the increase was significant upto I1 (Irrigation schedules @ 0.6 IW/CPE ratio) and S2 (mustered straw @ 5 t ha-1) which was also found to be statistically at par with I2 (Irrigation schedules @ 0.8 IW/CPE ratio) and S1 (wheat straw @ 5 t ha-1), respectively. Therefore, in this tract for soybean variety JS20-34, the application of irrigation schedules @ 1.0 IW/CPE ratios with compost @ @ 5 t ha-1 as a most profitable dose is being recommended for higher seed yield and net returns per hectare in Vertisols of South-Eastern Rajasthan
