SUMMARY

A field experiment was conducted during rabi seasons of 2015-16 and 2016-17 at Agronomy Farm, College of Agriculture, DBSKKV, Dapoli, Dist. Ratnagiri to study the effect of tillage practices and nutrient sources on performance of sweet corn. The experiment was laid out in split plot design with three replications assigning four tillage practices to main plots and five nutrient sources to sub plots. The results of the experiment indicated that higher value of growth attributes (plant height, number of leaves plant-1, leaf area index and dry matter accumulation plant-1) in green cob yield with sheath, green fodder yield and biological yield were recorded under tillage practice of one mouldboard ploughing + one pass of cultivator + one pass of rotavator (T4). Combined application of 75% RDN through chemical fertilizer + 25% RDN through vermicompost (S3) registered higher values of growth attribute green cob yield with sheath, green fodder yield and total biological yield.

Key words: Nutrient sources, tillage practices, sweet corn, green cob yield and green fodder yield
