Effect of nitrogen fertilization and residue management on the productivity of winter barley (Hordeum vulgare L.)

Nutrient management practices that concurrently improve soil properties and yield are essential for sustaining barley production. This study was conducted to evaluate the impact of balanced nitrogen fertilizer application involving farmyard manure (FYM) and residue management. The experiment had a factorial arrangement of five levels of mineral N and two organic fertilizer sources. The five levels of N fertilizer were applied in three replicates in combination with each of the two organic sources and a control (without organic source). Average plant height (PH), grain yield (GY), and straw yield (SY) were significantly (P <0.05) influenced by the main effect of N application and organic source; however their interaction was insignificant. The highest grain yield (103%) was obtained with 120 kg N compared to the control. The grain yield increased by 23.4% and 44% with FYM and residue, respectively, against the untreated control.
