Abstract

  The productivity of maize (Zea mays L.) is highly influenced by the combination of different sources of organic and inorganic sources of fertilizers. A field experiment was conducted to study the most suitable combination of different organic and inorganic sources of fertilizers to produce high grain yield of maize in Chitwan. The treatments consist of eight different combinations of organic and inorganic fertilizer sources i.e., T₁ = to supply 120 kg N ha^-1 as Urea, T₂ = to supply 60 kg N ha^-1 as Urea + 60 kg N ha^-1 as Farm Yard Manure (FYM), T₃ = to supply 60 kg N ha^-1 as Urea + 60 kg N ha^-1 as poultry manure (PM), T₄ = to supply 60 kg N ha^-1 as FYM + 60 kg N ha^-1 as PM, T₅ = to supply 30 kg N ha^-1 as Urea + 60 kg N ha^-1 as FYM + 30 kg N ha^-1 as PM, T₆ = to supply 60 kg N ha^-1 as Urea + 30 kg N ha^-1 as FYM + 30 kg N ha^-1 as PM, T₇ = to supply 30 kg N ha^-1 as Urea + 30 kg N ha^-1 as FYM + 60 kg N ha^-1 as PM and T₈ = control (no fertilizer) are arranged in Randomized Complete Block Design (RCBD) with four replications. The research result showed that, the highest grain yield (3.87 t ha^-1) was obtained with 50% N as Urea + 50% N as PM and the least (1.64 t ha^-1) was found at control treatment. The higher grain yield in this treatment was associated with maximum number of grain line (12.62), number of grains per cob (316.0) and thousand grain weight (299.9 g). Therefore, based on the research treatments, application of 120 kg nitrogen through the combinations of 50% N as Urea + 50% N as PM can be recommended to the farmers of Chitwan after confirming the results for few years.
