Abstract

Field experiments were conducted from 1997-2001 at Tamil Nadu Agricultural University, Coimbatore on sandy loam soil to study the effect of graded doses of NPK (100, 125 and 150 per cent of the recommended dose) under two population levels on the productivity of maize (Zea mays L.) under irrigated condition. The highest productivity was obtained with 150 per cent of recommended NPK with FYM @ 12.5 t ha in all the years and the effect of plant population was not significant. The interaction effect was found to be significant. The highest BC ratio of 1.66 was recorded in the treatment which received 125 per cent of recommended dose of fertilizer under recommended population.
