Abstract


Imbalance use of fertilizers along with inappropriate sources and application methods has attributed to reduced nitrogen use efficiencies (NUE) and crop productivity in Nepalese agricultural soils. Thus, use of right N source and appropriate application method is essential to reduce N losses and increase NUE, crop yield and farm economic return. A field trial was conducted in a randomized complete block design (RCBD) with seven treatments (three replications) using various N sources (regular urea, urea briquette, and three different blended fertilizers) and their application methods to assess their fertilizing efficiencies at Agricultural Research Station, Dasharathpur, Surkhet. Treatments showed significant effect (p < 0.05) for all the traits viz. plant and ear height (cm), stover and grain yield (t/ha), harvest index, and thousand grain weight (gram). Compared to recommended dose of fertilizer (RDF), grain yield advantage of blended fertilizer (10:26:26 NPK) in combination of Zinc followed by RDF+ Zn and urea deep placement (UDP) applied treatments were 7.8, 2.7 and 2.4% respectively. Among all, deep placement of urea briquette found economic for cultivation of Khumal Hybrid- 2 maize variety while producing similar yield (2.4% higher) with comparatively lower nitrogen dose (25% lower), higher agronomic nitrogen use efficiency (10.41 kg more), and economic benefit ($30.4) compared to RDF.
