Abstract:

A field experiment was conducted at research field of Islamic Azad University_Karaj Branch during 2009 to evaluation of Chickpea simulation using CROPGRO-Pea model at three sowing date, as a split plot experiment based on a completely randomized block design with three replications. In this experiment simulation of some traits such Biomass (B), Grain yield (GY) and Leaf Area Index (LAI), evaluated for some cultivars of Chickpea named Azad, Arman and Hashem using CROPGRO-Pea. According to results, model was successful in all of the traits simulation. Model explained well Biomass, as correlation coefficient in each sowing date was significant (p<0.01). Dimension variation d Wilmot coefficient for all of cultivars B, GY and LAI (S1-S3) was equal to (0.88-0.95), (0.77- 0.99) and (0.70-0.86), respectively. According to linearly regression correlation (1:1 line) simulation versus observed date for B, GY and LAI in all of the cultivars and sowing date obtained with equations of y = 0.876 x + 137.93 (R2 = 0.81), Y= 1.103x + 13, (R2= 0.99) and Y= 0.9x – 0.162 (R2= 0.72), respectively. These statistic parameters designated with high ability of model for simulation of B, GY and LAI trend in Chickpea under three different sowing date. This model is applicatory in prediction traits for sowing date management of Chickpea under Karaj climate.
