Fertilizer Recommendations

The Brazilian Government (IPEAN 1966) has developed fertilizer recommendation based on the following scheme. Equations have been developed for predicting the changes in soil nutrient levels per kilogram of fertilizer active ingredient applied.

But in general practice, the growers apply 200 to 300 g NPK (12:12:17) mixture, 500 g of lime and 300 g thermophosphate per plant per year. Organics used are castor, cotton and carapnut cakes, 1-2 kg per plant or poultry waste 1-2 kg or cattle manure

3-5 kg. In addition, foliar sprays of micro nutrients (manganese, boron, molybedenum) along with magnesium and occasionally calcium as well are given (Duarte and Albuquerque 1991).

Different types of organics are applied in varying quantities in the pepper growing countries. In India green leaves, dry leaves, wood ash, cattle manure, oil cakes, neem cake and bone meal are the common organics used. In Malaysia organic cakes, prawn refuse, guano, fish meal, etc are used. In Micronesia every pepper field will have a compost pit also. In addition sea cucumbers (Holothurian sp.) are dug into the soil around vines. (Zaiger 1964). Here the recommended fertilizer dose is a mixture of urea, cottonseed meal, potassium chloride and superphosphate at the rate of 0.66, 6.6, 1.1, 1.8 pounds per vine per year (Lawrence 1981).
