ABSTRACT
A field trial was conducted to assess the effect of different micronutrients at different concentrations, as foliar sprays, on the growth parameters and yield of ginger. Among the different treatments, maximum plant height (54.49 cm), number of leaves per tiller (18.98) and number of tillers per clump (16.16) were observed in the plants sprayed with Zn 0.5%. However,pseudostem girth (1.24 cm), leaf length (23.37 cm), leaf breadth (2.33 cm) and leaf area (36.26 cm2) were noticed in the plants sprayed with B 0.3%. Considering the projected yield per hectare, the highest yield (17.63 t) was produced by plants sprayed with Zn 0.5 per cent which was at par with plants sprayed with B 0.3% (17.44 t) and Mn 0.25% (17.33 t) per hectare. From net returns and benefit : cost ratio point of view, the best treatment (Rs. 6,82,423.00/ha and 3.43, respectively) was by foliar spray with Zn 0.5% followed by foliar spray with B 0.3% (Rs. 6,72,950.00/ha and 3.38, respectively).
Key words : Micronutrients, foliar spray, ginger
