Effect of Different Kinds of Water on Growth, Yield and Water Use Efficiency of Soybean

Abstract

A field experiment conducted at International Crops Research Institutefor the Semi-Arid Tropics (ICRISAT), Patancheru, India to study the effect of different quality of water on growth, yield and water use efficiency of soybean during rabi 2015-16. The experiment was laid out in randomized block design (RBD) and replicated fivetimes with three treatments i.e. untreated wastewater, treated wastewater and fresh water. The result of the present study indicate that untreated wastewater affect plant height, leaf area index, dry matter production, number of pod per plant, test weight, seed yield and straw yield significantly. Highest seed yield of soybean was observed in untreated wastewater (22.20 q ha-1) in relation to wastewater and freshwater. Higher value of growth attributes and yield attributes were found in untreated wastewater. Highest water use efficiency of soybean was also recorded in untreated wastewater treatment. This study, it concluded untreated wastewater increased growth attributes, yield attributes and yield and also water use efficiency due to presence of enough amount of nutrient in untreated wastewater and less amount of heavy metal that help to achieve maximum seed yield and water use efficiency in soybean.
