INFLUENCE OF BORON AND GROWTH REGULATOR ON GROWTH AND YIELD OF MAIZE (ZEA MAYS L.) NORTH EAST PLANE ZONEAbhinay Singh Patel, Joy Dawson, Lalit Kumar Sanodiya and Gagnendra Singh PatelAbstract To investigate the effect of boron and Gibberellic Acid (GA3) on growth and yield of maize, a field experiment was conducted at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences (SHUATS), Prayagraj (UP) in Rabi season 2022-23. The main objective of the experiment was to evaluate the Influence of boron and growth regulator on growth and yield of maize (Zea mays L.) north east Plane Zone. The research field of the treatment consisted of 3 levels of boron Soil application (3, 1.5 kg/ha) and foliar Application (1%, 0.5%) and 3 levels of Gibberellic Acid (50,100,150 ppm) foliar application and a control. The experiment was layout in Randomized Block Design (RBD) with 10 treatments and replicated thrice. Application of soil and foliar application of boron (0.5%+1.5 kg/ha) Along with GA3-150 ppm. produce highest plant height (205.79 cm), plant dry weight (157.74 g), crop growth rate (g/m2/day) (41.39 g/m2/day), more number of cobs per plant (1.67), number of grain row per cob (17.47), number of grain per row (33.63), seed index (25.630 g), higher seed yield (5.40 t/ha), higher Stover yield (9.60 t/ha), highest harvest index (35.97 %). |
