Fertilizer Trials with Turmeric (Curcuma domestics Val.) at Santa Cruz, Solomon Islands.

Abstract

In four experiments with turmeric (Curcuma domestica Val.) at Santa Cruz, Sobmoi Islands (S.l.) , potassium applications significantly increased the yield of rhizomes in all trials. There was some indication that sulphate of ammonia, phosphorus and a proprietary mixture of trace elements ma) increase yields in the presence of potassium. Urea applied alone depressed yields.
