Performance of wheat (Triticum aestivum L.) under different planting patterns and nitrogen levels

Abstract

The field experiment was conducted on the research farm of Department of Agronomy, Lovely Professional University, Phagwara (Punjab) on, “Performance of wheat (Triticum aestivum L.) under different planting patterns and nitrogen levels”. The field study was conducted in Split Plot Design with three planting patterns viz. 2 rows/bed, cross sowing, flat sowing in main plots and five nitrogen levels viz. 0 kg/ha, 40 kg/ha, 80 kg/ha, 120 kg/ha, 160 kg/ha in sub plots. The result revealed that significantly higher grain yield was obtained from two rows/bed (43.86 q/ha) followed by cross sowing (42.48 q/ha) and flat sowing (40.77 q/ha). Also bed sowing increased grain yield of wheat by 4.2 and 7.6 % than cross and flat sowing respectively. Also cross sowing method recorded significantly more grain yield than line sowing method. Grain yield was significantly higher with use of 160 kg N/ha (54.95 q/ha) as compared to all other nitrogen levels. There was subsequent and significant increase in grain yield of wheat with successive increase in nitrogen level from 0 to 160 kg/ha. Grain yield of 0 kg N/ha was significantly less than all other nitrogen levels. There was 100.4, 92.7, 60.0 and 19.6 percent increased in grain yield of wheat with the application of 160 Kg, 120 Kg, 80 kg and 40 kg N respectively as compared to 0 kg N/ha (control).
