 ABSTRACT

A field experiment was conducted during Rabi 2015-2016 to study the effect of plant growth promoters and growth retardants on growth parameters of mustard (Brassica juncea L.) at the research field of Dept. of Biological Sciences, SHIATS, Deemed to be university, Allahabad. The experiment consisted of plant growth promoters and growth retardants i.e., GA3, NAA, Cycocel and Ethrel. The growth promoters and growth retardants at concentrations of 100, 200 and 300ppm as foliar treatments. The experiment was laid out in RBD with three replications and the treatments were imposed at 30, 45, 60, 75 and 90 DAS. Among the all treatments application of NAA @ 100ppm has significantly increased total leaf area (cm2) per plant, leaf area index per plant, crop growth rate (CGR), relative growth rate (RGR). Cycocel @ 300ppm was found beneficial in decreasing leaf area (cm2) and leaf area index per plant.

Key words: Mustard, GA3, NAA, Cycocel, Ethrel, Growth Parameters.
