Effect of Weed and Nutrient management on Growth, Productivity and Protein content of Quality Protein Maize (Zea mays L.)

Author(s): P Deewan, SL Mundra, Dilip Singh, M Meena, R Verma and NK Sharma
Abstract: A study was conducted at Department of Agronomy, Rajasthan College of Agriculture, Udaipur during 2011 and 2012 crop season to assess the effect of weed management practices and level of fertility with emphasis on improving the productivity and quality of quality protein maize. The treatments were laid out in split-plot design with maize weed management practices as main plots and fertilizer application practices as subplots. Weed management practices significantly influenced the growth attributes as plant height, crop dry matter and leaf area index at different growth stages. Weed management measures during experimentation resulted in significant increase in all growth parameters (plant height, dry matter accumulation, LAI, RGR and NAR) compared to weedy check at different stages of crop growth. Application of Oxyfluorfen fb HW 30 DAS and metribuzin fb HW 30 DAS with non-significant difference between these treatments were found significantly superior in enhancing grain yield of maize compared to weedy check, atrazine fb HW 30 as well as HW 15 & 30 DAS. The results showed 174.55, 163.58, 153.31, 120.10 and 109.48 per cent increase in grain yield by weed free, Oxyfluorfen fb HW 30 DAS, metribuzin fb HW 30 DAS, atrazine fb HW 30 and hand weeding twice, respectively compared to weedy check. The biological yield was found similar result as grain yield. The level of fertility upto 125% RDF significantly improved plant height, crop dry matter accumulation, leaf area index, RGR and NAR at different growth stages and yield and quality of maize.
