Effect of superabsorbent on physiological traits and yield of wheat Azar2 cultivar under dry farming condition
Abstract:
Drought stress is one of the important factors limiting crop production. Increasing the water use efficiency is a strategy for enhancing the crop production. In order to study effects of superabsorbent on wheat’s growth in dryland, an experiment was conducted in research farm of agriculture Faculty of Zanjan University in 2010-2011. This experiment was conducted based on a random complete blocks design included four treatments of (0, 15, 30 and 45 kg Clophony superabsorbent per hectare with four replications. In this experiment Azar2 cultivar was used. The result of experiment showed that application of superabsorbent increased absorbing water by the plant and of relative water content which is causing the source strength by increased leaf area index and Chlorophyll index. Also, super absorbents’ application cased to increasing in the yield components including the number of fertile spike, the number of grain in spike and the grain weight which has finally led to the increase of grain yield. The grain yield increased in a linear trend with the raise of superabsorbent’s application and the maximum grain yield (2718 Kg/ha) was obtained using 45kg in hectare of Clophony superabsorbent. The results was showed that this treatment increase grain yield 156.5 percentage. In general could say that the application of super absorbent material in dryland condition could increase the grain yield by decreasing the drought stress affects and increasing the source and sink strength.
