Abstract:
A field experiment was conducted to study the effect of different tillage, fertility levels and weed management practices on growth and quality characters of wheat during two consecutive rabi seasons of years 2018-19 and 2019-20, respectively. The experiment was laid out in split plot design with two tillage practices viz., Conventional tillage (3 ploughing) and Zero tillage (ferti-cum-seed drill) along with three fertility levels viz., 100% RDF (120:60:40 NPK kg ha^-1), 75 % RDF + 25% RDN-FYM (6 t ha^-1) and 50% RDF + 50% RDN- FYM (12 t ha^-1) in main plot. Each main plot was further divided into four sub plots to accommodate sub plot treatments i.e. weed management practices comprising Weedy check, Weed free upto 60 DAS, Sulfosulfuron @ 30 g a.i. ha^-1 (POE) and Sulfosulfuron @ 30 g a.i. ha^-1 + Metsulfuron @ 4 g a.i. ha^-1 (POE) - Ready mixture. The results reported that the higher growth parameters viz. plant height, number of tillers, leaf area index and dry matter accumulation were recorded under zero tillage during both the experimental years. Among the fertility levels, application of 100% RDF (120:60:40 NPK kg ha^-1) recorded higher growth parameters. In case of weed management practices, weed free upto 60 DAS exerted significant effect on growth of wheat. However, in herbicidal treatments, post emergence application of Sulfosulfuron @ 30 g a.i. ha^-1 + Metsulfuron @ 4 g a.i. ha^-1 (POE) - Ready mixture noted higher values of above parameters. Protein content was failed to show any significant effect due to above treatments except weed management.
