Abstract

In order to evaluate the effect of combination vermicompost and Superabsorbent on quantitative and qualitative yield of cowpea under drought stress conditions, an experiment was conducted in Khorramshahr during 2017 cropping season in a split plot arrangement based on randomized complete block design with four replications. Experimental treatments consisted of drought stress in two levels (65 and 130) mm evaporation from class A evaporation pan in main plots and the combined effect of biological fertilizer of vermicompost and Superabsorbent at four levels (non-application of fertilizer (control), 5 t/ha vermicompost Compost + 75 kg/ha Superabsorbent, 5 t /ha vermicompost + 100 kg/ha Superabsorbent, 5 t /ha vermicompost) in sub plots. The results showed that drought stress had a significant effect on Grain yield, number of pods per plant, number of seeds per pod and Protein yield. Also, the combined effect of biological fertilizer of vermicompost and Superabsorbent had a significant effect on Grain yield and Protein yield. The highest Grain yield (202. 22 g/m2) was obtained from treatment with 5 tons per hectare of vermicompost + 100 kg/ha Superabsorbent (which did not have a significant difference with 5 tons per hectare of vermicompost + 75 kg/ha Superabsorbent) and lowest with mean 174. 26 g/m2 was obtained from non-application of fertilizer treatment. The interaction of drought stress and combined effect of biological fertilizer on vermicompost had a significant effect on Grain yield. The highest Grain yield was obtained with an average of 29. 225 kg/ha of irrigation after 65 mm evaporation from the pan and 5 tons per hectare of vermicompost + 75 kg/ha Superabsorbent. Finally, it can be said that the use of Superabsorbent and vermicompost in addition to increasing the quality and quantity of bean pollen can play a significant role in saving water irrigation.
