Influence of foliar spray of nutrients and plant growth regulators on physiological attributes and yield of finger millet (Eleusine coracana (L.) Gaertn.)

Abstract

The study was carried out to evaluate the effects of foliar application of nutrients and plant growth regulators on physiology and yield of finger millet. Results showed that foliar application of salicylic acid 40 ppm twice at pre and post flowering stage of crop growth significantly increased the physiological attributes viz., leaf area index, crop growth rate, relative growth rate and net assimilation rate when compared to other treatments. The days to 50% flowering and days to maturity was significantly lowest in foliar spray of salicylic acid 40 ppm twice at pre and post flowering stage of crop growth over other treatments. Among the treatments foliar spray of salicylic acid 40 ppm twice at pre and post flowering stage of crop growth recorded maximum grain yield (3593 kg ha-1) and straw yield (8735 kg ha-1) compare to other treatments.
