Use of organic fertilizer improves growth and yield of Triticum aestivum irrigated with textile wastewater

Abstract

Water scarcity is one of those issues. Reuse of wastewater from textile industries is a very common strategy to cope with water scarcity. Continuous use of effluent water for agricultural purposes results in negative impacts on physicochemical properties of soil and plant. Organic fertilizers are considered beneficial for soil and crop quality. To exploit the strategies to use this effluent water safely for crop production a pot experiment was conducted with different combinations of organic and inorganic fertilizers viz. T₁= Control (tap water + Recommended dose of NPK (130, 95 and 65 kg ha^-1), T₂=Wastewater + Recommended dose of NPK, T₃=Wastewater + Organic fertilizer (200 kg ha^-1) + Remaining NPK from inorganic fertilizer, T₄=Wastewater + Organic fertilizer (400 kg ha^-1) + Remaining NPK from inorganic fertilizer, T_{5 =}Wastewater + Organic fertilizer (600 kg ha^-1) + Remaining NPK from inorganic fertilizer and T₆=Wastewater + Organic fertilizer (800 kg ha^-1) + Remaining NPK from inorganic fertilizer. It was observed that integrated use of organic and inorganic fertilizer (800 kg ha^-1 organic and remaining of recommended dose from inorganic fertilizer + effluent water) enhanced the growth and yield of wheat crop. In a study found that the use of organic fertilizer could help mitigate the negative impact of textile effluent water on wheat growth.
