Effect of sulphur and zinc on growth and yield of Black gram

Abstract

A field experiment was conducted during Zaid (summer) season of 2024 at Crop Research Farm Department of Agronomy. The treatments consisted of 3 levels of Sulphur (10, 20 and 30 kg/ha) and 3 levels of zinc (10kg/ha, 0.1% and 0.2% foliar application) along with recommended doses of nitrogen, phosphorus and potash and a control (20-50-40 kg N-P-K/ha). The experiment was laid out in a Randomized Block Design with 10 treatments and replication thrice. Application of Sulphur (30 kg/ha) + Zinc (10kg/ha) (treatment 9) recorded higher Plant height (28.80 cm), maximum number of branches/plant (11.06), higher nodules/plant (16.44), higher plant dry weight (11.56 g), higher number of Pods/Plant (38.67), higher number of seeds/pod (6.93), higher test weight (37.44 g), higher seed yield (1504.55 kg/ha) and higher stover yield (2906.30) The treatment also recorded Maximum gross return (INR 98297.69 /ha), net return (INR 64701.09/ha) and B:C ratio (2.41)
