Effect of bioregulators on growth and yield of chickpea (Cicer arietinum L.)

A field experiment was conducted on Chickpea (Cicer arietinum L.) during Rabi season of 2017-18 at Agronomy Farm, Department of Agronomy, Dr. P.D.K.V., Akola to study the effect of bioregulators on growth and yield of chickpea. The experiment was laid out in FRBD with three replications and fifteen treatment combinations in each. The treatment consists of five bioregulators viz., water spray, Salicylic acid @ 50 ppm, Ethrel @ 200 ppm, Brassinosteroid @ 0.25 ppm and Nitrobenzene (20%) @ 500 ppm and three stages of application of bioregulators viz., at flower initiation, at pod formation and twice at flower initiation and pod formation stage. The result of study revealed that application of Nitrobenzene (20%) @ 500 ppm and Brassinosteroid @ 0.25 ppm remained at par and recorded higher values of all the growth characters except for root volume and root dry weight which, were not significantly influenced.
