The Different Irrigation Period Impacts to Sorghum Production and Yield Components

The material was hybrid 108 and 126. Under the different irrigation period, analyzed the relationship between yield and spike length, spike weight, spike grain weight, grain related to the yield and so other agronomic traits.The results showed that the Four processing than CK to increase production, the differences were very significant level;The production of two varieties and different irrigation yield differences were very significant level; Spike weight, spike grain weight were very significant positive correlation with yield. From the direct path coefficient analysis, spike grain weight of the direct path coefficient of output is the largest; spike weight impact on the production of indirect path coefficient is biggest by spike grain weight.
