Effect of different tree shading on the growth and yield of Curcuma aromatica salisb
Gopichand, RL Meena and RD Singh
Curcuma aromatica is a wild species, mostly distributed in hilly regions of India from North western to north eastern of Indian Himalaya. The studies were conducted in CSIR-IHBT, Palampur during 2002 to 2005 to monitor the effect of different shade tree species (Grevillea robusta, Morus alba and Jacaranda acutifolia), FYM application, plant spacing and in open field conditions on growth and yield of rhizomes. Observations were recorded on number of leaves, number of plantlets (side tillers), plant height, rhizome yield of second and third years of trials. The crop Curcuma responded significantly in number of leaves per plant and plant height, under shade trees and in open conditions. However, number of tillers per plants was not statistically significant. In the application of FYM 30 t/ha was produced highest statistically significant yield of rhizomes. In the same way regarding plant spacing, in all used spacing, all growth parameters were not statistically significant, in terms of number of leaves and number of plantlets (side tillers) per plant. However, in the case of plant height it was statistically significant. It has been recorded, that the yield of rhizomes after second and third years were statistically significant in all used tree shades by different species and in open conditions also. In the same manner, different plant spacing also influenced on the yield of rhizomes after second and third year’s harvest.
