Abstract :

Two years of field experiments were conducted to study the effect of different chemicals as a foliar application at 15 DAT and 30 DAT on growth and yield of paddy (variety paiyur-1) under irrigated condition in North Western Zone of Tamil Nadu during navarai season. Among the chemicals, foliar application of 0.5 per cent zinc sulphate at 15 and 30 DAT has recorded the maximum plant height (cm) and no. of tillers followed by uniconozole @ 50 ppm in this study. The yield attributing parameters viz., no of productive tillers, no. of panicles per m2, panicle length (cm), grain and straw yield (kg ha-1) were found to be higher due to foliar application of 0.5 per cent zinc sulphate at 15 and 30 DAT. The maximum mean grain yield of 6810 kg ha-1 with B C ratio of 2.69 was recorded for foliar application of 0.5 per cent zinc sulphate applied at 15 and 30 DAT and also increased the yield to the tune 37 per cent higher than control (4982 kg ha-1)
