An experiment was conducted to study the agronomic practices for growth and yield maximization of direct sown rice under water constraint situation. The main plot treatments comprised of three levels of irrigation viz., Conventional irrigation (M1 ), tensiometer based irrigation (M2 ) and deficit irrigation (M3 ) respectively and were tested with different water conservation practices viz., soil application of water saving crystals (WSC) @ 5 kg ha-1 (S1 ), foliar application of drought shield @ 3 liters ha-1(S2 ), soil application of humic granules @ 2.5 kg ha-1 (S3 ) and soil application of FYM @ 12.5 t ha-1 (S4 ). Interaction between different levels of irrigation and water conservation practices were significantly influenced. Tensiometer based irrigation along with soil application of humic granules @ 2.5 kg ha-1 (M2 S3 ) recorded the higher growth and yield parameters in direct sown rice.
