Effect of planting density and nutrient management practices on the yield of maize hybrids during kharif season
Author(s): P Naik, D Swain and A Nanda
Abstract: Field experiment was carried out to study the effect of planting density and nutrient management practices on the performance of maize hybrids in acidic soils of Odisha at the Central Research Station, Odisha University of Agriculture and Technology, Bhubaneswar, during 2014 in the coastal ecosystem in kharif season. The experiment was laid out in a split-split plot design with three replications. Two hybrids (Hishel and P3441) were allotted to the main-plots, two planting density (high-60 cm x 20 cm, normal-50 cm x 20 cm) to the sub-plots and three nutrient management practices i.e. SSNM (140:41:77 N:P2O5:K2O kg/ha) based on target yield (65.0 q/ha), Soil Test Crop Response (STCR) ((143:15:78) N:P2O5:K2O kg/ha) through fertilizer prescription equation target yield (65.0 q/ha) and RDF (120:60:60 kg N-P-K/ha) to the sub- sub-plots. The Hybrid P3441 influenced higher growth parameters, more plant population, produced maximum grain yield and stover yield to Hishel respectively. Similarly, the high plant geometry significantly yielded highest grain yield and stover yield as compared to normal plant geometry. Likewise, among the three nutrient management practices, STCR significantly resulted in highest grain yield and stover yield over RDF, but it remained at par with SSNM. The increase in grain yield and stover yield of STCR was 21.6% and 4.9% higher over RDF and 31.4% and 4.3% to SSNM.
