Yield and nutrient uptake of transplanted rice (Oryza sativa) with different moisture regimes and integrated nutrient supply

Abstract

A field experiment was conducted during kharif 2010 at Faizabad (Uttar Pradesh) to assessthe effects of moisture regime and integrated nutrient supply on yield, yield attributes and nutrients uptake of transplanted rice (Oryza sativa L.). Irrigation with 7 cm water at 1 day after disappearance of ponded water (DADPW) was superior to 3 and 5 DADPW in respect of yield, yield attributes and nutrient uptake. The highest grain yield (5.44 t ha−1) and straw yield (7.68 t ha−1), was recorded with 1 DADPW. Application of recommended dose of NPK (120:60:40 kg ha−1) applied through inorganic fertilizers was at par with green manuring + 75% NPK through inorganic fertilizers in respect of yield attributes, yield and total nutrient uptake. The maximum grain yield (5.21 t ha−1) and straw yield (7.45 t ha−1) was obtained with 100% NPK (120:60:40 kg ha−1), which was at par with green manuring + 75% NPK applied through inorganic fertilizers.
