Effect of Zinc and Thiourea Fertilizer at Different Stages for Growth and Yield of Green Gram

Abstract

The field experiment titled “Effect of zinc and thiourea fertilizer at different stages for growth and yield of green gram” was conducted during Zaid - 2023 at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology And Sciences, Prayagraj (U.P.) India. To study the Response of zinc and thiourea fertilizer at different stages for growth and yield of green gram. The soil of experimental plot was sandy loamy in texture, nearly neutral in soil reaction (pH 7.8), low in organic carbon (0.35%). The treatments consist of three levels of Zinc – 2.5 kg/ha, Zinc – 4.0 kg/ha, Zinc – 5.5 kg/ha. Three levels of Thiourea, Thiourea (500 ppm), Thiourea (500 ppm)- 30 DAS, Thiourea (500 ppm)- 45 DAS. The experiment was laid out in randomized block design with ten treatments each replicated thrice. Results revealed that the higher plant height (38.32 cm), higher number of nodules (23.55), higher plant dry weight (9.93 g/plant), higher crop growth rate (9.17 g/m2/day) higher number of pods/plant (22.88), higher number of seeds/pod (10.06), higher test weight (34.23 gm), higher seed yield (1222.69 kg/ha) and higher stover yield (2006.02 kg/ha) were significantly influenced with application of Zinc 5.5 kg/ha+ Thiourea (500 ppm) – 45 DAS. Higher gross return (94758.22 INR/ha), higher net return (65643.22 INR/ha) and higher B:C ratio (2.25) were also recorded in treatment-9 Zinc 5.5 kg/ha + Thiourea (500 ppm) – 45 DAS.
