Summary : This CD-ROM provides a guide for detecting nutrient deficiency and toxicity symptoms and managing nutrients in rice grown in tropical and subtropical regions. Some background information is included on the function of nutrients in the rice plant and possible causes of nutrient deficiencies, together with a description of nutrient deficiency symptoms, the effect of nutrient deficiency on plant growth, and the effect of flooding on nutrient availability. Estimates of nutrient removal in grain and straw have been included to help researchers and extension workers calculate the amount of nutrients removed from the field under different management systems. Strategies for preventing and treating nutrient deficiencies are described.
