Abstract


Inadequate site specific nutrient management and lack of optimum utilization of fertilizer have been major constraints for maize (Zea mays L.) production in Nepal. Therefore a farmers’ field experiment was conducted at Itahara and Rajghat VDCs of Morang district during 2015 December to 2016 May. Nutrient Expert (NE) and Farmers’ Fertilizer Practices (FFP) treatments were imposed in randomized complete block design having twenty farmers’ field as replication. The research explored highly significant result in terms of plant number per m2, cob numbers per m2, cob length, kernels per kernel rows, kernel rows per cob, test weight, grain, stover and biological yields and harvest index. Among two treatments tested NE showed the highest yield (8.06 tons ha-1) than FFP (4.52 tons ha-1). While comparing net revenue NE based fertilizer recommendation gave the significantly higher (NRs.151.116 thousand  ha-1) result than FFP (NRs.84.834 thousand ha-1) suggesting the adoption of NE practices to minimize the yield gaps and increasing the productivity of maize in Morang and adjoining agroclimatic conditions.
