Studies on nutrient uptake pattern in cardamom

A study was undertaken to know the uptake pattern of nutrients in different parts of cardamom of one-year-old and prepotent plants. The N, P and K. uptake increased with increase in dry matter production. Of the various nutrients, the total K uptake was more followed by N and P in both stages of crop and it suggests that crop requires more of K than N and P. Among the diffrernt plant parts, highest contribution to the total N uptake was by green leaves (44.69%) and tillers (29.6%) in one-year-old and prepotents respectively. The highest P and K uptake was by roots and grown up tillers in one-year-old plants and green leaves and tillers in prepotent plants respectively. The broad nutrient uptake ratio for per plant was 9:1:17 (N:P:K) respectively.
