Spraying with PGRs [plant growth regulators] promoted rice yield. The percent increase in the yield over control showed that PGR-h, CSL, and Aminos gave comparable bioefficacy. PGRs Vipul, Paras, and 110-R are classified as long-chain aliphatic alcohols; CSL, Aminos, and PGR-H as modified amino acids. A correlation between these characteristics and bioefficacy suggests that the latter PGRs promote larger biomass and more chlorophyll, which lead to efficient photosynthesis and higher productivity. The number of sprays (nine) used in the experiment was high to establish the utility of PGRs; dose and frequency of spraying still need to be optimized. Most of the nutritional characteristics were comparable, except for an increase in protein content, which is highly desirable. Reduced breakability during polishing also has commercial significance. Large-scale PGR spray trials in various agroclimatic zones and using different rice varieties are suggested to establish PGR utility for increasing rice production.
