Abstract:
A field experiment entitled “Effect of nitrogen and Sulphur levels on growth, yield and quality of maize (Zea mays L.)” was conducted at the Instructional Farm, Department of Agronomy, AKS University, Satna (M.P.) during the kharif season of 2019-20. A set of 12 treatment combinations including four nitrogen levels viz., 0 kg/ha (N₀), 80 kg/ha (N₁), 100 kg/ha (N₂) and 120 kg/ha (N₃) with three Sulphur levels viz., 20 kg/ha (S₁), 30 kg/ha (S₂) and 40 kg/ha (S₃) were evaluated. Treatments were replicated thrice as per Randomized Block design with Factorial concept. Crop sown with application of nitrogen @ 120 kg/ha combined application with Sulphur @ 40 kg/ha attained significantly higher plant growth and yield at all the growth stages of plant. The significantly higher plant height, number of leaves per plant, number of rows per cob, number of grains per cob, length of cob, grain and stalk yield per hectare and protein content of maize at maximum crop growth stage was recorded under the application of nitrogen @ 120 kg/ha combined application with Sulphur @ 40 kg/ha with the respective values of 213.88 cm, 13.53, 15.87, 316.93, 15.28 cm, 52.03 q/ha, 63.68 q/ha and 11.85%, respectively proved significantly superior to rest of the treatments. Result showed that maize variety when sown the application of nitrogen @ 120 kg/ha combined application with Sulphur @ 40 kg/ha recorded the maximum and significantly higher values of these parameters.
