Abstract: An experiment was conducted to know the impact of hydrogel and mulching on growth and growth attributes of maize in sandy soil. Experimentation was laid out in randomised block design with two factors (hydrogel and mulching) with three levels each and one additional control. Different levels of hydrogel and types of mulches, their interactions and a control were analysed statistically. The results were shown that maximum plant height was recorded with main effects of hydrogel @ 2.5 kg ha-1 at 30 DAS, rice straw mulch @ 5 t ha-1 at 30 and 60 DAS and their interaction at 30 DAS. The higher number of leaves (NL) plant-1 was recorded with rice straw mulch @ 5 t ha-1 at 60 and 90 DAS (14.31 and 10.71 respectively). Maximum leaf area (LA) was observed in main and interaction effects of hydrogel @ 3.75 kg ha-1 and rice straw mulch @ 5 t ha-1 at all the stages while it was on par with the treatments in which rice straw mulch @ 5 t ha-1 with hydrogel @ 2.5 kg ha-1 at 60 DAS and with other two levels of hydrogel were applied at 90 DAS. Main and interaction effects of hydrogel @ 2.5 kg ha-1 and rice straw mulch @ 5 t ha-1 recorded maximum dry matter production (DMP) plant-1 and root volume at harvest. When compare the control with treatments, control recorded the minimum plant height, NL, LA, DMP and root volume at harvest. Overall, application of hydrogel @ 2.5 kg ha-1 combination with rice straw mulch @ 5 t ha-1 shown the higher growth than the other treatments and their combinations.
