P. Vimala, N. H. Yeong and N. Shukor

Abstract

Nutrient contents and removal by potato (Famosa variety) were investigated. Nutrient removal rates of 78, 11,154,31 and 7 kg/ha of N, P, K Ca and Mg respectively were obtained for a yield of 27 t/ha. Nutrient removal ratio obtained waslL:2:22:4:1fo r N:P:K:Ca:Mg. About 50% of N, K and Mg,70% P and 8% Ca were removed by the tubers and the remainder by leaves and stems. About 1 kg/ha of each micronutrient was removed. Data presented can be used as a guide for formulating fertilizer needs of potato.
