Efficacy of growth retardants on physiology and yield of pearl millet under rainfed condition

A field experiment was conducted during kharif 2015-17 to study the efficacy of growth retardants on physiology and yield pearl millet at Durgapura (Jaipur). Growth retardants, viz. cycocel mepiquat chloride were sprayed @ 250, 500 750 ppm tillering (40 DAS) flowering (60 stages. The laid out in randomized block design with 4 replications. Results showed that plant height decreased, whereas chlorophyll content relative water increased significantly foliar application over rest treatments. higher specific leaf weight noted under control. Foliar produced grain However, it statistically par ppm. On other hand, fodder registered spray 250 ppm, control Maximum net returns benefit cost ratio accrued Thus, 40 60 DAS could be recommended for obtaining from rainfed condition Rajasthan.
