Abstract: A field experiment was conducted to assess the effect of foliar application of different micronutrients at different concentration on the yield and quality of ginger. Four different micronutrients i.e., zinc and manganese (0.25, 0.50 and 0.75 %), boron and iron (0.2, 0.3 and 0.4 % ) were foliar sprayed at 60, 90 and 120 days after planting. The experiment was laid out in randomized block design in three replications with total thirteen treatments. Among the different treatments, maximum number of rhizome per clump (17.78), length of fingers (12.06 cm), length of clump (21.14 cm) and essential oil content (1.59 %) were observed in the plants sprayed with Zn 0.5%. Whereas, girth of fingers (2.83 cm) and breadth of clump (13.12 cm) were noticed in the plants sprayed with B 0.3%. The highest yield/clump (238.20 g) was produced by plants sprayed with Zn 0.5% which was at par with plants sprayed with B 0.3% (235.99 g) and Mn 0.25% (229.72 g) ha-1. From net return and benefit: cost ratio point of view, the best treatment (Rs 6, 82,423.00/- ha-1 and 3.43) was by foliar spray with Zn 0.5% followed by foliar spray with B 0.3% (Rs 6,72,950.00/- ha-1 and 3.38, respectively).
