Abstract:
The experiment was conducted at Student’s Instructional Farm, Chandra Shekhar Azad University of Agriculture & technology, Kanpur during Kharif 2019 and 2020 on silty clay loam soils. The soil of the experimental field was neutral in reaction, testing medium in available P and K and low in available N with medium organic carbon content of 0.80. The treatments comprising of two irrigations methods: alternative wetting and drying (AWD), and flooding irrigation assigned to main plots, four nutrients levels (RDF+ ZnSO₄ @ 25 kg ha^-1 + FeSO₄ @ 10 kg ha^-1, RDF+ ZnSO₄ @ 25 kg ha^-1 and RDF+ FeSO₄ @ 10 kg ha^-1) in sub plots and four weed management practices including two herbicidal treatments (Chlorimuron ethyl and Fenoxaprop-p-ethyl), hand weeding along with weedy check to sub-sub-plots replicated were tested in Split-split plot design. On the basis of pooled data of two years revealed that highest economic returns in terms of total cost of cultivation, gross income, net return and benefit cost ratio was recorded during both the years of experimentation by irrigation methods, nutrients levels and weed management practices. Significant increase in total cost of cultivation, gross income, net return and benefit cost ratio was recorded due to the effect of irrigation methods. Highest total cost of cultivation, gross income, net return and benefit cost ratio was recorded with alternative wetting and drying (AWD) which was superior to flooded irrigation methods during both the years of experimentation. Among the nutrients RDF + ZnSO_4­+ FeSO₄ at par with RDF + ZnSO_{4 ­}proved excellent resulted in higher economic returns comparable to RDF treatment. The data on weed management practices manifest that all the herbicides used for control of weeds including hand weeding found to be highest economic return compared to weedy check. The highest net realization of Rs.70924 ha^-1. With highest B: C ratio of 1.49 was ensured under treatments hand weeding during both the year.
