Abstract

Nutrient uptakes of N, P, K ,Ca and Mg at 96, 19, 132, 44 and 23 kg/ha respectively were obtained. Nutrient uptake ratio obtained was 4:1:6:2:1 for N:P:K:Ca:Mg. Only 27% N, 22% P, 16% K, 6% Ca and 10% Mg of the total nutrient uptake were removed in the edible head for an economic yield of 5.6 t/ha. The rest were found in the non-edible leaves, stems and roots. Micronutrient uptake was less than 0.5 kg/ha. Data presented can be used as a guide for formulating fertilizer needs of broccoli grown on peat.
