Seed hardening, foliar spraying and their combined effect on biochemical parameters in green gram (Vigna radiata L. Wilckzek) cv. GAM-5

Abstract

A field experiment was conducted to evaluate seed hardening, foliar spraying and their combined effect on biochemical characters in green gram. The mung bean var. GAM-5 was imposed with seed hardening treatments and also for foliar spray using CaCl2 2% & 1%, CCC 500 mg/L, CCC 1000 mg/L, NAA 25 mg/L, NAA 50 mg/L. The trial was laid out in RBD with three replications and sixteen treatment combinations including five seed hardening treatments, five foliar spraying treatments, five seed hardening treatments with foliar spraying and one absolute control treatment during summer season of 16 and 2017. These treatments were evaluated for their biochemical parameters at field conditions. It was found that continuous increase in chlorophyll content was noted up to 60 DAS, thereafter it decreased during both the seasons at senescence stage. It is clear that there was increase in nitrogen content and seed protein content in all the treatments like seed hardening, foliar spraying singly or their combined effect as compared to control. Therefore, the treatment T11 was more efficient in chlorophyll content in leaves, nitrogen content and protein content in seed as compared to other treatments and control.
