Abstract
A field study was carried out at Student’s Experimental Farm, Department of Agronomy, at research farm of Chandigarh University of Agricultural Sciences and Technology, Punjab to evaluate the “Effect of split plot application of Potassium and Nitrogen on Wheat (Triticum aestivum L.) Under Punjab condition” emend. The experiment was set up in a split-plot design replicated thrice, consisting of 15 treatment combinations, viz. of potassium @ 30 kg/ha [K1: 100% as basal dose-(RFP); K2: 50% as basal dose + 50% at active tillering; K3: as basal dose + 75% at active tillering] and 5 treatments of nitrogen @ 120 kg/ha in split ratios of [N1: 50% as basal + 25% at jointing + 25% at booting stage (REP); 25% as basal dose + 75% at active tillering; N3: 25% as basal dose + 50% at active tillering + 25% at booting; N4: 50% as basal + 50% at active tillering; N5: 0% as basal + 75% at active tillering + 25% at booting]. The results revealed that growth parameters and yield increased with the application of potassium in two equal splits in the ratio of 50:50 as compared to the treatment where potassium was given in one split as 100% basal dose. Splitting of potassium in the ratio of 50:50 produced higher grain yield by 48.24%, 46.76% and 45.54%, straw yield by 80.42%, 78.54% and 76.85%, respectively over 100% as basal dose. Application of nitrogen in three splits with reduced basal dose in the ratio of 25: 50: 25 improved growth and yield as compared to recommended practice. The increase in grain yield and straw yield was 48.41% and 82.36% respectively over 100% as basal dose. Application of nitrogen in three splits with reduced basal dose in the ratio of 25: 50: 25 improved growth and yield as compared to recommended practice. The benefit cost ratio with the application of potassium in two equal splits in the ratio of 50: 50 with reduced basal dose of nitrogen (25:50:25). The increase in wheat production is possible by selecting adapted genotypes with improved.
