Nutrient Management Research for Paddy Rice in Guizhou

IPNI-2013-CHN-GZ16

Most of the nutrient management studies on paddy rice in Guizhou Province in the past were focused on medium to high fertility soils and largely ignoring the rice grown in the low to medium fertility soils. In order to improve paddy rice yield and nutrient management practices, three field experiments were carried out to test the effects of different N, P and K rates on rice yield and the soil nutrient status in the growing season.

Nutrient management for paddy rice grown in soils with different fertility in Guizhou province


Interpretive Summary

2013

Most of the nutrient management studies on paddy rice in Guizhou Province in the past were focused on medium to high fertility soils and largely ignoring the rice grown in the low to medium fertility soils. In order to improve paddy rice yield and nutrient management practices, three field experiments were carried out to test the effects of different N, P and K rates on rice yield and the soil nutrient status in the growing season.

2011

The objective of this study was to evaluate different nutrients on yield and quality of kidney bean, one of the main summer vegetables in Guizhou. There were eight fertilizer treatments consisting of no fertilizer (CK), an optimal treatment (OPT) and treatments individually omitting N, P, K, Mg, B, and Mo within the OPT. The results obtained from this experiment and some other related experiments will be used to develop the best nutrient management for kidney bean in the region.
