A field experiment was conducted at College of Agriculture, Padannakkad, Kerala Agricultural University, Thrissur, Kerala, Indiato study the effect of hydrogel (super absorbent polymer) and mulching on physical and chemical properties of sandy soil in maize (Zea mays L.). The experiment was conducted in factorial randomized block design having two factors with three levels each and one additional control. Different levels of hydrogel and types of mulches, their interactions and a control were analysed statistically on physical properties of soil like porosity and bulk density and chemical properties like available soil N, P2O5 and K2O. Results revealed that main effects of hydrogel applied @ 3.75 kg ha-1 and coirpith compost mulch @ 2.5 t ha-1 recorded the maximum soil porosity. The residual nutrient status with respect to available soil N and K2O recorded maximum with main and interaction effects of treatments contain hydrogel @ 1.25 kg ha-1 and rice husk mulch @ 5 t ha-1 and available soil P2O5 was recoded maximum with hydrogel @ 3.75 kg ha-1 and rice husk mulch @ 5 t ha-1. Control recorded the high available soil N, P2O5, K2O content than the remaining treatments.
