Effect of growth regulators and nipping on Bio-chemical traits and yield attributes of chickpea (Cicer arietinum L.)

Abstract

The treatment was comprised of foliar spray of naphthalene acetic acid (NAA), maleic hydrazide (MH) and nipping along with untreated control. NAA 50 ppm and MH 60 ppm concentrations and nipping were used in experimentation. Observations were recorded at 30, 50, 70 DAS and maturity. The observations had been studied on biochemical, yield and yield attributes parameters of the JG-14. Foliar spraying of naphthalene acetic acid, maleic hydrazide and nipping at 30 and 50 DAS were performed well. It is concluded from the result that foliar application of NAA 50 ppm at 30 and 50 DAS and nipping at 30 and 50 DAS were found increase the all parameters of plant like total chlorophyll content, nitrate reductase activity, protein content in seed, leaf nitrogen content, total phenol content, number of pod per plant, pod weight plant-1, 100 number of seed plant-1, seed weight plant-1, grain yield (g) plant-1, grain yield quintal hectare-1 and harvest index followed by foliar application of NAA 50 ppm at 30 DAS and nipping of shoot at 30 and 50 DAS respectively except plant height.
