摘要：

Field experiment was conducted at Research farm of CCS Haryana Agricultural University, Hisar during rabi season of 2005-06 to study the applicability of DSSAT model for barley variety-BH-393 with respect to sowing dates and row spacing. Results revealed that the prediction of phenological development was over estimated with in the acceptable limits (1). The prediction of peak leaf area index (LAI) was significantly on the higher side and deviated between -0.1 to 0.8 and also within the acceptable limits. The model mostly overestimated the yields and yield attributes. The model predicted highest grain yield for 15 cm row spacing in the first date of sowing.
