Effect of phosphorus and plant growth regulators on growth and yield of blackgram

A field experiment was conducted during Zaid season 2023 at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Sciences and Technology. To determine “Effect of phosphorus and plant growth regulators on growth and yield of Blackgram”. The result revealed that treatment 8 [Phosphorus (50 kg/ha) + GA3 (10 ppm)] recorded significantly higher plant height (32.47 cm), higher plant dry weight (12.36 g), maximum number of pods/plant (17,01), maximum number of seeds/pod (7.53), higher seed yield (907.30 kg/ha) and higher stover yield (1890.50 kg/ha). Highest gross return (80146.00 INR/ha), net return (51442.30 INR/ha) and B:C ratio (1.79) was recorded in treatment 8 [Phosphorus (50 kg/ha) + GA3 (10 ppm)] was found to be productive as well as economically feasible.
