Evaluation of Varieties and Gypsum on Growth and Yield of Groundnut (Arachis hypogaea)

A field experiment was conducted during Zaid 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) to study treatments consisting of Varieties viz. K-1812, K-6 and K-Amaravati and three levels of Gypsum viz. 200, 300, 400 kg/ha. The results revealed that treatment 3 (K-1812 (Lepakshi) + Gypsum (400 kg/ha) recorded significantly higher number of nodules/plant (52.00), higher dry weight (30.96 g), crop growth rate (30.63 g/m2/day), relative growth rate (0.0447 g/g/day), maximum number of pods/plant (39.93), maximum number of kernels/pod (2.0), Shelling percentage (72.4%), Pod yield (3.67 t/ha), higher seed yield (2.72 t/ha), higher haulm yield (4.66 t/ha) and higher harvest index (31.55%), maximum gross return (1,54,260.00 INR/ha), maximum net return (1,04,999.00 INR/ha) and maximum benefit cost ratio (2.13).
