Agronomic Practices to Enhance Nutrient Acquisition, Grain Quality, Resource-Use Efficiency in Direct- Seeded Aerobic Rice in Eastern India

摘要

Aim: Rice ( Oryza sativa L.) is mainly grown in the rainy season in eastern India on rainfed uplands with a low average productivity of 1.0-1.4 t ha~(-1). Erratic rainfall leading to moisture stress and poor cultivation practices are the key reasons for low yields and rice grain quality in the area. Hence, the current study was designed to investigate the effects of irrigation scheduling, soil adjuvant and sowing methods on yield, grain quality and resource-use efficiency in aerobic rice.
