Effect of supplemental irrigation on yield and yield components and correlation between varieties cultivated in spring chickpea

To study the effects of supplemental irrigation and varieties on yield and other morphological traits, peas, experimental research farm in 1389 in agricultural research stations were run Boroujerd. Irrigation including irrigation at flowering stage, flowering and pod + pods week week and pea varieties include Vision, free and Hashem split plot experiment in a randomized complete block design in three replicates were compared. In this study, irrigation at flowering stage performance + highest pods week (3 / 1458 kilograms per hectare) compared to other irrigation in the experiment was. the figures ideals and free performance and more characters other significant difference and superiority to figure Hashem had. the study of stepwise regression characteristics variables, economic performance, harvest index and gap formation of the first pod from the soil surface with R2 = 0 / 996 Most justify produced models for the dependent variable yield biologically had entered the model. Also, for dependent variable economic performance, harvest index, biological yield, distance form the first pod from the soil surface and pods in the main stem with R2 = 0 / 998 into the regression model was. Analysis of the path indicated that the economic performance of most direct impact and gap formation of the first pod from the soil surface less direct effect and the highest indirect effect on the performance of biological showed. Analysis of correlation indicated that the most significant correlation between biological and economic performance is performance. Also with all the traits of biological functions and economic performance had a significant positive correlation. Among these traits, traits hollow pods negative correlation with other traits and meaningful self-revealed.
