Pre-sowing seed hardening and foliar spray with plant growth regulators is an easy, low cost and low risk technique and also an alternative approach recently used to mitigate the effect of abiotic stresses in agricultural production.
The mung bean var. GAM-5 was treated with seed hardening treatments and also for foliar spray using CaCl2 2% and 1%, CCC 500 mg/L, CCC 1000 mg/L, NAA 25 mg/L, NAA 50 mg/L. during summer season of 2015–16 and 2016–17. The trial was laid out in RBD with three replications and sixteen treatment combinations.
The results indicated a significant improvement in morpho-physiological growth parameters, dry matter production and thereby yield potential increased due to the application of plant growth regulators and agrochemical under field conditions. Among the different treatments, seed hardening with 2% CaCl2 + 1% foliar spraying at 30 DAS (T11) treatment significantly improved most of morpho-physiological parameters and thereby yield in green gram followed by the seed hardening treatments of Cycocel 1000 mg/L + foliar spraying at 30 DAS (T13) and seed hardening with NAA 50 mg/L + foliar spraying at 30 DAS (T15).
