The reaction of yield, yield components, morphological and quality traits of soybean varieties to cutting irrigation in different growth stages
Abstract:   (4721 Views)

Selecting an appropriate variety given the conditions of each region is an agricultural solution to achieve a desirable performance in plants in drought stress conditions. An experiment was conducted in a split plot arrangement based on randomized complete blocks design with three replications in Moghan plain in 2015. Main-plots were normal irrigation, cutting irrigation during the growth stages, cutting irrigation during flowering stages and cutting irrigation during grain filling stage and early season varieties including Williams, M9 and Zan were sub-plots. The results showed that, except seed protein percentage and the protein yield, all traits (including yield, yield components, morphological and qualitative traits) were influenced by the interaction between cutting irrigation and the varieties. The results of comparing the means of the data demonstrated that cutting irrigation decreased growth and yield of all varieties. The highest economic yield (4.28 tons /hectare) and biological yield (9.33 tons/hectare), morphological traits (the height of plant, the number of leaves in each plant, the distance between the first pod from the earth and the number of secondary branches in each plant), oil seed percentage (26.13) and oil yield (111.83) were observed in Williams under the normal irrigation. Moreover, the lowest values for these traits were obtained in Zan in cutting irrigation condition in grain filling phase. Therefore, Williams was the best variety under water shortage conditions and Zan was the most sensitive variety to the cutting the irrigation in Moghan plain.
