Abstract:

Field experiments were carried out to study the effect of planting density and nutrient management practices on the performance of maize hybrids in acidic soils of Odisha in the coastal ecosystem in kharif season during 2015, 2016 and 2017. The experiment was laid out in a split-split plot design with three replications, using two hybrids (Hishel and P3441) allotted to the main-plots, two planting density to the sub-plots and three nutrient management practices to the sub- sub-plots. The Hybrid P3441 influenced higher growth parameters, more plant population (86.7thousand /ha), produced maximum cob yield (7122 kg/ha-11.1%), grain yield (6202 kg/ha-7.9%) and stover yield (17791 kg/ha-14.4%) to Hishel (6413 kg/ha, 5739 kg/ha, 15550 kg/ha) respectively. Similarly, the high plant geometry (50cm x 20cm) significantly yielded highest cob yield (7497 kg/ha-18.5%), grain yield (6122 kg/ha-7.7%) and stover yield (17783 kg/ha-14.3%) as compared to normal plant geometry (60cm x 20cm) i.e.6327 kg/ha, 5684 kg/ha and 15557 kg/ha, respectively. Likewise, among the three nutrient management practices, Soil Test Crop Response (STCR) significantly resulted in highest cob yield (7564 kg/ha), grain yield (6328 kg/ha) and stover yield (17786 kg/ha) over RDF (6219 kg/ha, 5310 kg/ha and 14792 kg/ha), but it remained at par with Site-Specific Nutrient Management (SSNM) 7237 kg cob /ha, 6074 kg grain /ha and 17228 kg stover /ha. The increase in cob yield, grain yield and stover yield of STCR was 21.6 %, 19.2 % and 20.2% higher over RDF and16.3 %, 14.4 % and 16.5 % to SSNM. The hybrid P3441 influenced maximum net return of Rs.55488/ha (18.0%) higher with B:C ratio of 1.40 as compared to hybrid Hishel [net return Rs 47041/ha, B:C (1.22)]. Similarly, the high plant geometry (50 cm x 20 cm) significantly found highest net return of Rs.55368 of 17.4% more with B:C ratio of 1.41 over normal plant geometry (60 cmx20 cm) i. e. net return of Rs.47161/ha with B:C ratio of 1.34. Likewise, Soil Test Crop Response (STCR) practice significantly increased maximum net return of Rs.57921/ha with 38.8% higher with B:C ratio of 1.46 over RDF(net return  Rs.41741/ha with B:C 1.11) and SSNM (net return of Rs.54141/ha with B:C ratio of 1.38).
