Abstract
A field experiment was conducted during Zaid season (2022) to determine the Influence of calcium and gibberellic acid on growth, yield and economics of summer groundnut (Arachis hypogea L.). Experiment was laid out in Randomized Block Design (RBD) with 3 replicates of 10 treatments. The results showed that treatment 9 of [Ca (40kg/ha) + GA3 (120ppm)] recorded significantly higher plant height (60.4 cm), more dry weight (45.95g), maximum number of nodules/plant (16.4), maximum number of pods/plant (24.60), maximum number of kernels/pod (1.93), higher seed index (37.8 g), higher seed yield (2.02t/ha), higher haulm yield (4.11 t/ha) and higher harvest index (32.83 %). Maximum gross returns (1,25,778.00 INR/ha), maximum net returns (87,853.50 INR/ha) and highest benefit cost ratio (2.32) was also recorded in treatment 9 of Ca (40kg/ha) + GA3 (120ppm) as compared to other treatments.
