| Abstract: | In order to study the relationship between yield,maize ear treats and organ matter,N-OH,available P and K, we selected field block with different soil nutrition in Mei county, Shaanxi province. The result showed that under the level of N-OH,available P and K in the soil, the ear length,seed length,kernel per row,kernel per ear,1000-kernel weight and yield increased with increasing the available N,P and K. To improve organ matter,available P and K would increase yield for there are defiance organ matter,available P and K in the soil. |
