Abstract:
A field experiment was conducted at Agricultural Research Station, Kalaburgi, University of Agricultural Sciences, Raichur, during the rabi 2018-19 to assess the potency of plant growth regulators and nutrients which could be used to mitigate water stress and reduce the yield reduction in chickpea under drought condition. During investigation the treatments followed were foliar spray of 2% urea, seed priming with 2% CaCl₂, 0.1% boron, salicylic acid (100 ppm), cycocel (100 ppm), and formulations like pulse magic 8 g/l and chickpea special 8 g/l were evaluated under non irrigated condition on chickpea variety JG11. The result indicates that grain yield significantly reduced under water stress. All treatments showed promising effect on crop health under non-irrigated conditions. However, the significantly larger effect was noticed foliar spray of chickpea magic 8 g/l at 50% flowering. The plants followed foliar spray of chickpea magic 8 g/l attained significantly increased plant height, number of branches, total dry weight, relative water content, photosynthetic rate, number of pods per plant, 100- seed weight, grain yield and harvest index over control under drought condition.
