PERFORMANCE OF PLANT GROWTH REGULATORS AND MICRONUTRIENT ON GROWTH AND YIELD OF MAIZE (ZEA MAYS L.)SANIKOMMU JAYA SOWMYA, SHIKHA SINGH AND VIKRAM SINGHAbstract A field experiment was conducted during kharif 2020 at Crop Research Farm, SHUATS, Prayagraj (U.P) to study the performance of plant growth regulators and micronutrient on growth and yield of Maize (Zea mays L.). The experiment was laid out in Randomized Block Design with eight treatments each replicated thrice. It was observed that T3 Superzyme 900 ml/ha foliar spray at 30 and 60 DAS was found to be the best treatment for obtaining growth and yield attributes such as plant height (196.20 cm), dry matter accumulation (573.07 g/m2), Crop growth rate (2.42 g/m2/day), cob length (18.77cm), cob girth (14.47 cm), No. cobs per plant (1.53), No. grains per cob (331.53), No. of grains per row (29.80), No. of rows per cob (11.36), seed index (29.00 g), grain yield (5.23 t/ha) while net returns (110770.78 INR/ha) and B:C ratio (2.40) were also recorded in application of Superzyme 900 ml/ha foliar spray at 30 and 60 DAS. From the above experiment, it was concluded that application of Superzyme 900 ml/ha foliar spray at 30 and 60 DAS was found to be more productive as well as economic. |
