abstract
A field experiment was conducted during kharif season of 2023 at Crop Research Farm Department of Agronomy, Naini Agricultural Institue, Sam Higginbottom University of Agriculture, Technology and Sciences, to determine “Effect of molybdenum and weed management practices on growth and yield of Blackgram”. The treatments consisted of three levels of molybdenum (1, 1.5, 2 kg/ha) and weed management practices are done (hand weeding 20 and 35 DAS, pendimethalin 3.30 liters/ha). The experiment was laid out in a Randomized Block Design with 10 treatments and replication thrice. The result revealed that Treatment 9 [Molybdenum (2.0 kg/ha) + Pendimethalin (3.30 l/ha) + Hand weeding at 35 DAS] recorded significantly higher plant height (46 cm), maximum number of branches/plant (11.27), maximum number of nodules/plant (33.20), higher plant dry weight (13.13 g), maximum number of pods/plant (29.60), maximum number of seeds/pod (11.30), higher seed yield (1.87 t/ha), higher stover yield (4.02 t/ha), highest weed control efficiency (74%) and highest weed control index (93.3%). The aforesaid treatment also recorded maximum gross return (INR 117024.00), net return (INR 77525.5) and B:C ratio (1.96).
