The field experiment entitled “Influence of Nitrogen levels and Microbial inoculants on Yield and Economics of French bean" was conducted during rabi season, 2022 at Crop Research Farm in the Department of Agronomy, Naini Agriculture Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj Uttar Pradesh. The soil in the experimental area was sandy loam with pH (8.0), Organic Carbon (0.42%), Available N (180.58 kg/ha), Available P (15.54 kg/ha), and Available K (198.67 kg/ha). The treatment consisted of two factors, Factor-1 levels of Nitrogen (75,100,125 kg/ha) and factor-2 Microbial inoculants (Rhizobium, PSB & Rhizobium +PSB). The experiment was layout in Randomized Block Design (RBD) with 10 treatments and replicated thrice. It was noticed that application of Nitrogen levels and Microbial inoculants had a significant effect on growth, yield, and yield parameters. The results indicated that the higher seed yield (22.47 q/ha), stover yield (50.08 q/ha), harvest index (30.95%), gross return (133601.00 INR/ha), net return (91333.00 INR/ha) and benefit-cost ratio (2.16) were observed in treatment 6, which involved the seed inoculation of Rhizobium and PSB along with the soil application of Nitrogen 100 kg/ha. So, in order to get higher productivity and returns from French bean, application of 100kg N/ha along with seed inoculation with phosphate solubilizing bacteria (PSB) and Rhizobium should be followed in sub-humid condition of Prayagraj, UP.

The purpose of this study is to study the influence of microbial inoculants and molybdenum on the yield and economics of chickpeas (Cicer arietinum L.). The research was carried out at Crop Research Farm, SHUATS, Prayagraj, India in Rabi 2022. The study included biofertilizer and three levels of Molybdenum (0.5, 1.0 and 1.5 kg/ha). The experiment was designed using a randomized block design with 10 treatments, each replicated thrice. The soil in the experimental area was sandy loam with pH (7.8), Organic Carbon (0.43%), Available N (181.58 kg/ha), Available P (15.45 kg/ha), and Available K (197.64 kg/ha). The results indicated that the higher seed yield (1638.35 kg/ha), stover yield (3539.00 kg/ha), gross return (105101.20 INR/ha), net return (71599.20 INR/ha), and benefit-cost ratio (2.14) were observed in treatment 9, which involved the seed inoculation of Rhizobium and PSB along with the soil application of Molybdenum 1.0 kg/ha.

The field experiment entitled “Evaluate the growth and yield of chickpea influenced by Biofertilizers and Molybdenum on Chickpea (Cicer arietinum L.)" was conducted during rabi, 2022 at Crop Research Farm in the Department of Agronomy, Naini Agriculture Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj Uttar Pradesh. The experiment was layout in Randomized Block Design (RBD). The treatment consisted of three levels of Biofertilizer (Rhizobium, PSB and Rhizobium + PSB), Molybdenum (0.5, 1.0 and 1.5 kg/ha) and control. The soil in the experimental area was sandy loam with pH (7.8), Organic Carbon (0.43%), Available N (181.58 kg/ha), Available P (15.45 kg/ha) and Available K (197.64 kg/ha). Seeds are sown at a spacing of 30 × 10 cm to a seed rate of 80 kg/ha. The application of Rhizobium + PSB and Molybdenum 1.0 kg/ha significantly increased the Plant height (49.90 cm), No. of nodules/plant (32.60), Dry weight (35.33 g), Number of Pods/plant (60.20), Number of seeds/pod (1.80), Seed yield (1638.35 kg/ha) and Stover Yield (3539 kg/ha) of chickpea over the control.

The field experiment "Influence of Biofertilizer and Zinc on Yield and Economics of Barley" was carried out during the Rabi season of 2022 at Crop Research Farm in the Department of Agronomy, Naini Agriculture Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh. The treatment consisted of Biofertilizers [Azotobacter, PSB and Azotobacter + PSB], Zn (20, 25 and 30 kg/ha) and control. The experiment was designed using Randomized Block Design (RBD) and reproduced three times. The soil in the experimental area was sandy loam with a pH of 8.0, 0.62% organic carbon, 225 kg/ha available nitrogen, 38.2 kg/ha available phosphorus, and 240.7 kg/ha available potassium. Azotobacter + PSB + Zn 30 kg/ha increases grain production (4.29 t/ha), straw yield (6.72 t/ha), gross return (108675 INR/ha), net return (78555 INR/ha) and B:C (2.61).
