Background: Pre-sowing seed priming and foliar spraying 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.Methods: Seeds of Mung bean var. GAM-5 were primed and also foliar spraying at 30 DAS with CaCl2 2% and 1%, Cycocel 500, 1000 ppm, NAA 25, 50 ppm during summer season of 2015-16 and 2016-17.Result: The results indicated a significant improvement in morpho-physiological traits, growth parameters, biochemical constituents and thereby yield due to the application of PGRs. Seed priming with 2% CaCl2 followed by 1% foliar spraying at 30 DAS (T11) significantly improved most of morpho-physiological parameters viz., plant height, number of branches per plant, days to 50% flowering, maturity, leaf area, chlorophyll content, seed protein content, number of pods per plant, number of seeds per pod, test weight, pod length, yield per plant, yield per hectare, harvest index in green gram followed by the seed priming with Cycocel 1000 ppm followed by foliar spraying at 30 DAS (T13) and seed priming with NAA 50 ppm followed by foliar spraying at 30 DAS (T15). The treatment T11 was more efficient.

Background: 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. Methods: 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. Result: 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).

Background: Mung bean is important pulse crop having low productivity. Considering the constraints, it is worthwhile to study the influence of different seed hardening and foliar spraying treatments on the production potential of mung bean. Methods: Mung bean var. GAM-5 was imposed 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. These treatments were evaluated for their dry matter partitioning at field conditions. Result: The leaf dry matter decreased in all the treatments after 60 DAS at the time of pod development upto harvest. There was a very less rate of increase in the stem and root dry matter from pod development stage till the harvest leading to an increase in pod weight. The translocation process must have been more prominent in the treatment CaCl2 2% seed hardening + 1% spraying at 30 DAS (T11) than rest of the treatments and was less in untreated control treatment indicating that photosynthesis and translocation efficiency increases by seed hardening and foliar spraying treatments with agrochemical and growth regulators for increasing the pod yield. Therefore, the treatment T11 was more efficient in dry matter production and its partitioning in leaves, stem, root and pods by allocating maximum dry matter to the pods.
