There were considerable differences in amounts of nutrient uptake by the rice cultivar Chuanxiangyou 9838 in different growing periods under no till rape-rice rotation in Sichuan. The rice cultivar absorbed the highest quantity of N in the elongation stage and followed by its maturity and tillering stages. Uptake of P kept a steady increase from seedling stage to its maturity, and the maximal uptake of K occurred during the elongation to earing stages. Based on the nutrient uptake characteristics of the rice cultivar Chuanxiangyou 9838, good nutrient management practices were therefore developed. Application of N should be conducted in early stages and no latter than its elongation. If the soil N supplying ability was not adequate after elongation, an extra N application should be considered to guarantee high yield and quality of the rice. Basal application of P was considered as a proper practice. When the soil as too sandy with low nutrient holding capacity, or too acidic or alkaline with strong ability to fix up P and lose bioavailability, it was better to split P fertilizer to meet requirement at its latter stages. K fertilizers could be applied in early to middle growing stages. If the soil was sandy, it should consider an extra K application after earing stage. It was found that the proper N application rate for the rice cultivar Chuanxiangyou 9838 under no till rape-rice rotation was approximately 165 kg/hm 2 N with a goal of 11 tonnes of rice yield.
