The current rapid increase in irrigation water consumption is considered unsustainable and threatens the world food production. Therefore, it is mandatory to promote modern techniques and to manage existing conventional irrigation methods. The present study was attempted to determine the effects of different irrigation frequencies and rice straw incorporation rates on yield and water productivity of the wheat crop. The experiment was arranged with randomize complete block design involving nine treatments (RS 0 I 7 , RS 0 I 15 , RS 0 I 22 , RS 1 I 7 , RS 1 I 15 , RS 1 I 22 , RS 2 I 7 , RS 2 I 15 and RS 2 I 22) under three replications. Results exposed that the incorporation of rice straw with different irrigation frequencies significantly improved physico-chemical properties of soil. Moreover, soil bulk density, infiltration rate, pH, electrical conductivity significantly decreased and soil porosity significantly increased under all treatments. Furthermore, maximum crop yield and crop water productivity of 7706.4 kg/hm 2 and 1.92 kg/m 3 respectively were found under RS 1 I 15 treatment. Based on experimental results it can be concluded that irrigation frequency and incorporation of rice straw had significant effects on the physico-chemical properties of soil, total grain yield and water productivity of the wheat crop. However, this study suggested that the wheat crop yield and water productivity could be increased by incorporating 1 t/hm 2 rice straw with 15 d of irrigation frequency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
