Abstract

Direct and indirect effects of foliar nutrient levels on the yield of black pepper were studied in a field trial. The foliar levels of N, K, Ca and Mg increased following fertilizer application in the rainy season. Five nutrient elements, P, K, Ca, Mg and S, were found to exert direct and indirect effects on the yield of green pepper as evidenced from simple correlation and path coefficient analyses. Of these, P and K were found to be of greater importance in enhancing yield. The period just prior to flushing was found to be the most suitable time for leaf sampling.
