Phosphorus and zinc effects on pearl millet variety 'ABV-04' during the rainy season (Kharif) of 2021 were studied in field experiments with nine treatments, i.e., P at 30, 40, 50 kg/ha and Zn at 5, 15 and 25 kg/ha respectively, at Crop Research Farm, Department of Agronomy, Faculty of Agriculture, SHUATS, Prayagraj, India (U.P). The treatments comprised T1 – 30 kg P/ha + 5 kg Zn/ha, T2 – 30 kg P/ha + 15 kg Zn/ha, T3 – 30 kg P/ha + 25 kg Zn/ha, T4 – 40 kg P/ha + 5 kg Zn/ha, T5 – 40 kg P/ha + 15 kg Zn/ha, T6 – 40 kg P/ha + 25 kg Zn/ha, T7 – 50 kg P/ha + 5 kg Zn/ha, T8- 50 kg P/ha + 15 kg Zn/ha, T9 – 50 kg P/ha + 25 kg Zn/ha. Results revealed that the application of 50 kg P + 25 kg Zn recorded highest ear head length (18.90 cm), maximum grain production (2.66 t/ha), maximum stover yield (3.90 t/ha), highest gross and net returns of (1,33,667.00₹) and (92,861.00₹), respectively. b.c ratio (2.26) was also found.
A Field Research done at Sam Higginbottom University of Agriculture, Technology, and Sciences in Prayagraj, Uttar Pradesh in Kharif to study the interactive effect of different levels of Nitrogen and Sulphur on yield and economics of sunflower (Helianthus annuus L.) var. DRSH -1. Experiment was undertaken on an agricultural research farm in 2021. Nitrogen is a primary nutrient element which plays a major role in growth and development of plant and As Sunflower is an oilseed crop, requires optimum level of Sulphur to produce good quality oil. Thus optimum levels of Nitrogen and Sulphur increases the production and productivity of sunflower crop. A combination of 120 kg N/ha + 45 kg S/ha yielded the maximum Seed yield (1446.20 kg/ha), Stover yield (2794.39 kg/ha), the highest gross return (94.003 x 103 INR/ha), net return (58.619 x 103 INR/ha), and benefit: cost ratio (B:C ratio) (1.66).
Background: Pearl millet can grow in a variety of environments. Pearl millet is a viable alternative to sorghum in areas where it cannot thrive. When it comes to soil moisture utilisation and heat tolerance, sorghum and maize cannot compete with pearl millet. Objectives: Effects of nitrogen and phosphorus on growth parameters and yield of pearl millet Methods: With the goal of studying the effect of nitrogen and phosphorus on growth and yield of Pearl millet (Pennisetum glaucum L.) Var. ABV - 04 under a Randomized block design with 9 treatments (T1-T9) The experimental results revealed that 120 kg N/ha + 60 kg P/ha produced maximum plant height (214.37), plant dry weight (46.74) and yield parameters ear head length (20.77 cm), number of grains/ear head (1972.0), grain yield (2.68 t/ha), and stover yield (3.77). Conclusion: The combination of 120 kg nitrogen/ha and 60 kg phosphorus/ha proved to be the most advantageous to farmers, resulting in 214.37-cm plant height, 46.74-gm plant dry weight, 1972 grains per ear head, and 2.68 ta grain and 3.26 ta stover yields, respectively.
A field study was conducted during the growing season of 2021 at the crop research farm of the Department of Agronomy at Sam Higginbottom University of Agriculture, Technology, and Sciences, Prayagraj in the North Eastern plains of Eastern Uttar Pradesh with the objective of studying the effects of nitrogen and phosphorus on growth, yield, and economics of cowpea (Vigna unguiculata L.) Var. Gomati VU 89 under a randomised block design, comprising of 9 treatments, of which treatments (T1-T9) with different combinations of nitrogen and phosphorus, which are replicated thrice. The experimental results revealed that 25 kg N/ha + 50 kg P/ha recorded Maximum plant height (69.02 cm), number of branches/plant (12.33), number of nodules/plant (4.0), highest plant dry weight (15.32 gm), crop growth rate (4.80 g/m2/day), test weight (18.57 g), number of pods/plant (20.13), number of seeds/pod (15.1), seed yield (1243.97 kg/ha), harvest index (32.0%). T9 25 kg N/ha + 50 kg P/ha resulted in a higher net return (34.05 x 103/ha), gross return (63.44 x 103/ha), and benefit-cost ratio (2.16).
