Revolutionizing Rice Farming: New Methods Boost Yields and Save Water
Efficient management of water and nitrogen is crucial for successful rice farming. A study evaluated different methods of water and nitrogen management for irrigated rice. The researchers conducted field and pot experiments to compare the effects of various water management techniques (continuous submergence, alternate wet and dry soil, moist soil) and nitrogen fertilizer rates (no fertilizer, 60 kg/ha, 90 kg/ha) on rice yield, water use, and economic returns. Results showed that rice yields were similar in continuous submergence and alternate wet and dry conditions, but lower in moist soil. Higher yields were achieved with 90 kg/ha of nitrogen fertilizer. The combination of continuous submergence with 90 kg/ha of nitrogen fertilizer resulted in the highest grain yield. Overall, the study found that proper nitrogen and water management can significantly impact rice productivity and water use efficiency.
