RESUMO
An experiment was carried out in the field to ascertain the "Influence of organic manures and zinc on growth, yield and economics of Pearl millet (Pennisetum glaucum L.)” during Zaid 2022 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology, and Sciences Prayagraj (U.P) (Pennisetum glaucum L.). The results showed that treatment 6 [Vermicompost (2.6 t/ha) + Zinc (15 kg/ha)] significantly increased plant height (169.2 cm), dry weight (94.90 g), ear head length (26.4 cm), maximum number of grains/ear head (2046), grain weight/ear head (23.4 g), test weight (9.21 g), grain yield (3.90 t/ha), stover yield (8.20 t/ha), and harvest index (32.24%). In comparison to other treatments, treatment 6 [Vermicompost (2.6 t/ha) + Zinc (15 t/ha)] also had the highest total returns (91919 INR/ha), highest net returns (64269 INR/ha), and highest benefit cost ratio (2.32).
RESUMO
A field experiment was conducted during Zaid season (March to June; Summer season crop) of 2022 at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology And Sciences, Prayagraj, Uttar Pradesh, India to determine the “The effect of phosphorus and molybdenum on the growth and yield of summer Cowpea (Vigna unguiculata L.)”. The results showed that the treatment 9 [Phosphorus (50 kg/ha) + Molybdenum (2 kg/ha)] recorded significantly higher plant height (73.43 cm), higher number of nodules per plant (17.66), higher plant dry weight (23.07 g/plant), higher crop growth rate(18.87g/m2/day) maximum number of pods per plant (15.10), maximum number of seeds per pod (14.67), higher seed index (16.03 g), higher seed yield (1550.27 kg/ha) and higher stover yield (1615.50 kg/ha) and higher harvest index (49.05%) was recorded in treatment 8 [Phosphorus (50kg/ha) + Molybdenum (1.5kg/ha)]. Similarly, maximum gross return (94954.8 INR/ha), higher net return (65670.3 INR/ha) and highest Benefit Cost ratio (2.24) was also recorded in treatment 9 [Phosphorus (50kg/ha) + Molybdenum (2kg/ha)] as compared to other treatments.
