Effect of Phosphorus and Hydrogel on Growth and Yield of Maize (Zea mays L.)

A field experiment was conducted during Rabi 2022 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, (U.P) India. To evaluate the effect of phosphorus and hydrogel on growth and yield of maize (Zea mays L.). Both phosphorus and Hydrogel was broadcasting in the field before sowing and mixed well in the soil. The growth attributes which was plant height (231.54 cm) and dry weight (178.19 g/plant) was significantly increased with increasing the level of phosphorus (25, 50, 75 kg/ha) and hydrogel (2.5, 5, 7.5 kg/ha) and maximum was obtained with application of phosphorus (75 kg/ha) and hydrogel (7.5 kg/ha) with highest effective number of cobs/plant (2.60), cob length (14.63 cm), number of rows/cob (11.91), number of grains/cob (326.39), grain yield (4.95 t/ha), stover yield (6.72 t/ha), harvest index (42.30%).
