A field study was conducted during Rabi season of two consecutive years 2019 and 2020 in Crop ResearchFarm at Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, Uttar Pradesh,India to determine the role of biofertilizer and growth regulators on production of Indian mustard (Brassicajuncea L.). For the yield and yield parameter viz., seed yield (1.943 and 2.034 t/ha), stover yield (6.747 and6.964), harvest index (22.31 and 22.56 %) and test weight (3.38 and 3.47 g) significantly higher were recordedduring the years 2019-20 and 2020-21 in treatment combination B4 (PSB + VAM + Azotobacter), respectively.Among the growth regulators results revealed that is significantly higher recorded the seed yield (1.842and 1.978 t/ha) and stover yield (6.768 and 6.954 t/ha) during the years 2019-20 and 2020-21, respectivelyin the treatment G1 [Gibberellic acid 50 ppm (0.05 g/l)].

Field studies were conducted during rabi season of 2014-15 to 2015–16 to at Crop Research Farm, Block E ofSHUATS, Department of Agronomy, Naini Agricultural Institute, SHUATS, Prayagraj, to study effect oftillage practices, nitrogen and zinc management on wheat (Triticum aestivum L.) productivity and quality inthe NEPZ. The experiment comprising two treatments in main plots (conventional and minimum tillage)in sub plots six organic and inorganic nitrogen management (viz., NU0; Control, NU1; 50% RDN throughinorganic with 50% RDN through organic, NU2; 25% RDN through inorganic with 75% RDN throughorganic, NU3; 50% RDN through inorganic with 50% RDN through organic, NU4; 25% RDN throughinorganic with 75% RDN through vermicompost organic N5; 100% RDN through inorganic and sub plotsviz., control and zinc,was laid out in split split plot design with three replications. Results revealed thatsignificant and maximum (grain yield, 3.89 t/ha; number of leaves per plant, 17.25 and 18.12 at 75 and 90DAS; organic carbon, 0.451%) respectively were recorded in crop cultivated by conventional tillage. Further,significantly the highest soil organic carbon (0.462%) was recorded in minimum tillage compare toconventional tillage. Significant and maximum and yield attributes (grain yield, 4.14 t/ha; straw yield, 8.39t/ha; plant height, 84.42 and 94.58 cm at 90 and 105 DAS; number of leaves per plant, 17.82 and 18.25 at 75and growth attributes 105 DAS, respectively were recorded in applied nitrogen management NU3 50%RDN through inorganic with 50% RDN through organic treatment. Similarly, the maximum buildup of soilorganic carbon 0.462%; Pore space, 48.407 and 48.135% at depth 0-15 and 15-30 cm and significant andmaximum the lowest (soil pH, 7.24; S, 13.19; Mn, 4.56 and Cu, 0.53; Bulk density, 1.329 and 1.316 g cm-3 at0-15 and 15-30 cm; Particle density, 2.517 g cm-3 at 15-30 cm, respectively were recorded in NU3 treatment.The foliar application of 0.5% zinc sulphate had pronounced effect on soil properties and crop performanceof wheat under rainfed conditions.

A field experiment was conducted at Crop Research Farm (CRF), SHUATS, Allahabad, during the kharif season of 2017 with 12 treatments replicated thrice in randomized block design, to determine the effect of row spacing with different levels of Phosphorous and biofertilizer on growth and yield of maize (Zea mays L.). This treatment consisted of two treatment of planting geometry 60 cm x 20 cm, 45 cm x 20 cm, three different levels of phosphorous 60 kg/ha, 80 kg/ha and 100 kg/ha. Seed was inoculated and uninoculated with PSB. The results revealed that spacing of 60 cm x 20 cm and 80 kg P ha -1 with phosphate solubilising bacteria was found to be the best treatment for obtaining higher grain yield (5.22 t ha -1 ), harvest index (43.13%), test weight (28.33 g) and other growth and yield attributes like higher net returns (Rs 40,303.50/-ha -1 ) and B:C ratio (2.18) was also observed. However, seed inoculation with PSB showed positive differences in effecting the grain yield.
