Abstract:
A field experiment entitled “The effect of tillage and weed management practices on yield and nutrient uptake in wheat (Triticum aestivum L)” was carried out at Agronomy research form, Department of Agronomy, R.V.S.K.V.V. Gwalior (M.P.) during the Rabi season of 2019-20 and 2020-21.To find out the effect of various tillage and chemical weed control practices on growth, yield attribute, yield, nutrients content, after harvesting the wheat crop, and economics of various treatments. The combination of the five tillage systems (CT, ZT, MT) and seven weed management practices (Solfosulfuron, Metsulfuron-Methyl, Clodinafop, Solfosulfuron+ Metsulfuron-Methyl, Clodinafop+ Metsulfuron-Methyl, Two hand weeding, and weedy check) was laid out in Split Plot Design and replicated thrice. The results reported that the higher growth parameters viz., number of tillers, leaf area, dry weight per plant protein and starch content were recorded under during both the experimental years. Among the zero tillage conditions recorded higher growth parameters. In the case of chemical weed practices, weed-free up to 60 DAS exerted a significant effect on the growth of wheat. However, in herbicidal treatments, post emergence application of clodonafop + metsulfuron - methyl, (60+4) g/ha ready mixture noted higher values of the above parameters after weed-free treatment. Protein and starch content was to show significant effect due to the above treatments tillage and chemical weed practices.
