Colleagues



I want to simulate the crop production under different planting date treatments, I used the soil water content (80%) to decide planting dates, Therefore, I get the following mangement set, but whatever I adjusted the PH20L, PH20U, PH20D, PSTMZ, and PSTMN under automatic magement item, the model tell me  "the condition is not met during the planting widows", then exit. 



How can I used the automatic planting function in DSSAT4,  Can anybody tell me what wrong with my process? Thank in advance.
