Abstract:
The present study (2017-19) was carried out to study the impact of organic and inorganic nitrogen fertilization on nutrient uptake in wheat crop under sewage water irrigation. The experiment consisted of three irrigation sources i.e. treated sewage water (TSW), canal water (CW) and tube well water (TW); and seven nitrogen sources i.e. control (T₁), 100% RDN through chemical fertilizers (T₂), 100% RDN through vermicompost (T₃), 50% RDN through chemical fertilizers + 50% RDN through vermicompost (T₄), 100% RDN through FYM (T₅), 50% RDN through chemical fertilizers + 50% RDN through FYM (T₆), 50% RDN through chemical fertilizers + 25% RDN through FYM + 25% RDN through vermicompost (T₇). The results revealed that the treatments receiving treated sewage water recorded significantly higher nutrients (N, P, and K) uptake in grain and straws of wheat crop during both the years. While among the nitrogen sources, treatment T₂ exhibited higher nutrient accumulation over rest of the treatments. However, T₂ remained at par with T₄, T₇ and T₆. Hence, use of sewage water under wheat cultivation with integrated nitrogen application of chemical fertilizers and organic manures proved to beneficial in terms of nutrient accumulation.
