Studies on the Nutrient Uptake in Robusta and Poovan

Studies were undertaken to assess the level and uptake of nutrients at different stages of growth of Robusta and Poovan at the Tamil Nadu Agricultural University, Coimbatore. The cultivars showed different levels of uptake of nutrients and a differential distribution in various parts. Leaf was found to be the specific tissue for diagnosing the N, P, Ca and Mg at all stages of growth. For K, however, sheath was found to be the most suitable tissue.
