Influence of partially acidulated phosphate rocks (PAPR) on cocoa yield on alfisols
An experiment to study the influence of partially acidulated phosphate rocks (PAPR) on yield of bulk cocoa had been carried out on Alfisols. The experiment was arranged according to Randomized Complete Block Design with 7 treatments, i.e. control, PAPR, 15, 30, 60, 75 and 100 percent, respectively. Each treatment was replicated three times. The bulk cocoa trees used in the experiment were planted in 1986 at Rajamandala estate, PTP XII, West Java. Elevation of the site is 45 m a.s.l. The result showed that PAPR 15 percent to 75 percent are as effective as TSP for dry bean yield.
