Abstract

A field experiment was carried out during summer seasons of two consecutive years 2010 and 2011 to assess the effect of irrigation levels and agrochemicals. Application of eight irrigations (at seedling, six leaf, knee-high, before tasseling, 50% tasseling, 50% silking, grain formation and grain filling stages) significantly improved  plant height at harvest over rest of irrigation treatments during both the years. On pooled mean basis, the magnitude of increase in plant height at harvest due to eight irrigations was in the order of 28.41, 18.49, 10.96 and 4.31 per cent over four, five, six and seven irrigations, respectively.  Dry matter accumulation at 50 Day after sowing and at harvest significantly improved with eight and seven irrigations over four, five and six irrigations during both the years of the study.
