Abstract:
A field experiment was conducted in Agricultural Research Station during Kharif
seasons from 2014-15 to 2017-18 to study the effect of planting density and nutrient
management on the performance of full season maize hybrids NK-6240 & K 3110 which
were located in main plot and two plant densities viz. 83,333 plants /ha (60 x 20 cm spacing)
and 83,333 plants /ha (50 x 20 cm spacing) as well as three levels of nutrients viz.
Recommended dose of fertilizers (RDF – 200: 60: 50 kg NPK ha -1 ) , Soil Test Crop Response
(STCR – 260-94-61 kg NPK ha -1 ) and Site Specific Nutrient Management (SSNM – 190-84-
143 kg NPK ha -1 ) were located in sub-sub plot in split plot design with three replications.
Overall the results indicated that there was no significant difference observed among the
different nutrient management practices (SSNM, STCR & RDF), plant density (60X 20cm &
50X 20cm) and hybrids (NK 6240 & K 3110) in terms of yield, yield attributes, net returns
and B C Ratio. So farmers can go with recommended dose of fertilizers to maize crop.
