Abstract

A field experiment was conducted during rabi season in the year 2020-21 and 2021-22 at agricultural farm of Sangam University, Bhilwara (Rajasthan) India, to evaluate the effect of irrigation water (Treated industrial effluent) and integrated nutrients management on growth and yield of Mustard crop. The trial was consist of four irrigation water (IW0) freshwater, (IW1) 25% effluent + 75% fresh water, (IW2) 50% effluent + 50 % fresh water, (IW3) 75% effluent + 25% freshwater and four integrated nutrient management (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% fresh water) in combination with INM2 (75% RDF through inorganic fertilizer + 25% through Vermicompost recorded the highest plant height, number of primary branches, number of secondary branches, chlorophyll content and number of green leaves per plant and grain yield in comparison to remaining treatment combination, whereas it was significantly at par with treatment IW0 (100% RDF through inorganic fertilizer).

Conclusion

From the results, it can be inferred that concentrated industrial effluents is heavily loaded with pollutants which negatively affect plant growth and yield by interfering with physiological process. However, on dilution, toxic effects of industrial effluents are reduced. Moreover, the 25% share of industrial effluents had effect on growth, yield and chemical parameters could be stimulatory rather inhibitory. On the basis of this study, it can be concluded that the diluted industrial wastewater can be used to meet the water requirements that can also improve growth and yield of mustard crop. Among the integrated nutrient management, application of 75% RDF through inorganic fertlizers + 25% through vermicompost found best among all nutrient management options and may be suggested for higher growth and yield in mustard crop and soil health sustainability as compare to application of 100% RDF through inorganic fertilizers during both the years of experimentation.
