Effect of seed priming and foliar spray of bio-regulators on biochemical properties of chickpea (Cicer arietinum L.) under conserved moisture condition of Bhal region of Gujarat

Abstract

Three year field experiment conducted at Bhal region of Gujarat to examine the effect of seed priming and foliar spray of stress mitigating bio-regulators under conserved moisture condition on biochemical properties of chickpea. Drought is the most limiting factor for production in semi -arid ecosystem of Gujarat. Under changed climate scenario due to variability in rain fall pattern problem of drought aggravated. Experiment treatments were applied as seed soaking with thiourea (500 ppm), salicylic acid (50 ppm), thioglycolic acid (50 ppm) before sowing and foliar spray of water, thiourea (1000 ppm), salicylic acid (100 ppm) thioglycolic acid (100 ppm) at vegetative & flowering stage & one is absolute control in both of factors. Bio-regulator spray was done at vegetative & flowering stage and samples were collected after 10 days of each spray for analysis. Among the treatments imposed, result revealed that seed priming of thiourea @500 ppm recorded significantly higher values of chlorophyll A (mg/g/ fresh weight), chlorophyll B (mg/g/ fresh weight), total chlorophyll (mg/g fresh weight) and proline content (mg/100g) in second sampling. Foliar spray with thiourea @1000 ppm recorded significantly higher data of chlorophyll A (mg/g/ fresh weight), chlorophyll B (mg/g fresh weight), total chlorophyll (mg/g/ fresh weight) and proline content (mg/100g) were recorded in second sampling.
