Influence of Treated Industrial Effluent as Irrigation Source and Integrated Nutrient Management on Growth Parameters and Yield of Wheat (Triticum aestivum L.)

Abstract

Integrated nutrient management (INM) is a better approach for supplying nutrition to the crop by including organic and inorganic sources of nutrients will not only help sustain the crop productivity but also will be effective in improving soil health and increasing the nutrient-use efficiency. The present study explores to influence of Treated Industrial Effluent as Irrigation Source and Integrated Nutrient Management on Growth Parameters and Yield of Wheat (Triticum aestivum L.). A field experiment was conducted during rabi season in the year 2020-21 and 2021-22 at the agricultural farm of Sangam University, Bhilwara (Rajasthan), India. The experiment was laid out in a Randomized Block Design (factorial) with four irrigation water treatments- (IW0) freshwater, (IW1) 25% effluent+75% fresh water, (IW2) 50% effluent+50 % fresh water, (IW3) 75 % effluent+25% freshwater and four integrated nutrient management treatment- (INM0) 100% RDF through inorganic fertilizer, (INM1)75% RDF through inorganic fertilizer +25% through FYM, (INM2)75% RDF through inorganic fertilizer + 25% through Vermicompost, (INM3) 50% RDF through inorganic fertilizer + 25% through FYM + 25% Vermicompost. The result revealed that treatment IW1 (25% effluents + 75% freshwater) in combination with INM2 (75% RDF through inorganic fertilizer + 25% through Vermicompost recorded the highest plant height, number of tillers/plant, number of green leaves per plant, chlorophyll content, leaf area index and yield in comparison to remaining treatment combination. The interaction between irrigation water quality and INM was significant for grain yield and straw yield, indicating that the effect of INM on yield depends on the quality of irrigation water. Since the treated water can be used to irrigate crops, it is now imperative that industrial wastewater be reused and recycled. Additionally, soil fertility and quality can be consistently maintained through integrated nutrient management, which helps to lessen a number of issues like food insecurity and peasant poverty.
