Abstract:

Two maize hybrids (NK-6240 and 900 M GOLD) were compared for yield and yield components and correlations were worked out among the yield parameters at various target yield levels in an experiment conducted at Mudhol Agricultural Research Station of University of Agricultural Sciences, Dharwad, Karnataka, during kharif 2014. The experiment was laid out in split plot design with three replications. 900 M GOLD with target yield of 140 q ha-1 (130.53 q ha-1) recorded significantly higher grain yield over rest of the treatments. Correlation Co-efficient in maize revealed that grain yield of maize was positively correlated with yield components. Among yield components correlation of cob length (0.993**) was significantly higher followed by cob girth (0.974**). Based upon the correlations, cob length was also found a suitable marker for selecting a maize hybrid for higher grain yield along with other yield attributes i.e. cob girth, test weight and number of kernel rows cob-1.
