Comparison of the effect of deficit irrigation by alternate furrow and conventional irrigation methods on the dry matter of sorghum bicolor
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 6, Issue 8
Abstract
In order to compare the alternate furrow and conventional irrigation methods and regimes and their effects on the dry matter accumulation process of sorghum bicolor (Payam variety) at different growth stages, this research was performed in a split plot experiment based on the randomized complete block method with three replications in the Zahak Agricultural Research Station. The main treatments considered included irrigation regimes (irrigation after 80, 130, and 180 mm accumulative evaporation from pan class A), and sub-treatments included irrigation methods (complete irrigation of furrows, Intermittent alternate furrow irrigation, fixed alternate furrow irrigation with two-line planting pattern, and this three irrigation methods with a line planting pattern and conventional irrigation). The results showed that the amount of dry matter in the aerial part of sorghum bicolor was significantly influenced by irrigation regimes, sampling stages, and irrigation methods. Moreover, the interaction between these factors and the rate of this factor was decreased by an increase in irrigation interval and a reduction in the soil’s available moisture. The amount of dry matter in the aerial part of sorghum bicolor (338.2 gr/m2) was more in the irrigation interval of 80 mm evaporation than that of the other irrigation regimes. An increase of (283.5 gr/m2) was indicated in the accumulation process compared with the other stages in the third stage of sampling. The maximum amount of plant dry matter (333.3gr/m2) was obtained from the conventional irrigation method. The results showed that the best performance pattern for this irrigation method for obtaining the maximum amount of dry matter is the fixed furrows method with a line planting pattern.
