An experiment was undertaken at Uttar Banga Krishi Viswavidyalaya, Pundibari, West Bengal to study the effect of boron, iron, manganese and zinc on the growth and yield of turmeric during the year of 2010-11, 2011-12, 2012-13 and 2015-16. The experiment was laid out in randomized block design with three replications. Different treatments of the experiment were T1 - control (no micronutrients), T2 - soil application of boron (as borax) @ 25Kg ha-1, T3 - soil application of manganese (as MnSO4) @ 25Kg ha-1, T4 - soil application of iron (as Fe2SO4) @ 25Kg ha-1, T5 - soil application of zinc (as ZnSO4) @ 25Kg ha-1, T6 - foliar spray of manganese (as MnSO4) @ 0.5% after 60 and 90 days of planting, T7 - foliar spray of iron (as Fe2SO4) @ 0.5% after 60 and 90 days of planting, T8 - foliar spray of boron (as borax) @ 0.5% after 60 and 90 days of planting and T9 - foliar spray of zinc (as ZnSO4) @ 0.5% after 60 and 90 days of planting. The results revealed that soil application of boron (as borax) @ 25Kg ha-1) gave the highest yield (11.13 kg/3 m2 and 22.45 t/ha) which was also statistically at par with foliar spray of boron as borax @ 0.5% at 60 and 90 days after planting (10.59 kg/3 m2 and 21.36 t/ha). The lowest yield (7.17 kg/3m2 and 14.45 t/ha).was recorded in the control treatment (i.e. without micronutrient application). The highest cost benefit ratio (1: 2.04) was recorded with soil application of boron (as borax) @ 25Kg ha-1 followed by foliar spray of boron (1: 1.95) (as borax) @ 0.5% at 60 and 90 days after planting.
