The influence of rice-duck farm soil on the nitrogen content of different varieties of japonica rice

Nitrogen fertilizers are widely applied to increase rice yields, but excessive fertilization poses an environmental risk. It has been shown that rice-duck farming can be more efficient in terms of N use by improving growth. Several pathways have proposed for how ducks may improve growth paddy fields. The aim this study was investigate the isolated effect farm soil on rice, namely content different plant organs and whether it differs among varieties. In a 116-day greenhouse pot experiment, six Japonica varieties (JinU99, Jinyuan98, Jindao18, Jinyuan89, Jinhei1 Jindao201) were grown fertilized duck no-duck after which their numbers surviving grain-producing plants compared. straw leaf concentrations positively influenced while roots, recorded only two Grain differed varieties, not significantly type. Overall, leaf, roots some grain higher than those soils farming. This first time demonstrates alone influence growth, certain organs.
