Abstract: Experiments were conducted at the College of Horticulture on nutritional aspects of clove, to study the nutrient deficiency symptoms as well as the distribution pattern of nutrients in starved clove plants. The deficiency symptoms were induced in clove seedlings in sand culture. The distribution pattern of P, S (anions) and Ca (cation) were studied in the nutrient-starved seedlings employing radio isotopes. Besides, the annual nutrient removal and the seasonal fluctuations in the foliar nutrient concentration were studied in bearing clove trees. Older leaves were the first to exhibit 'hunger signs' due to the stress induced by N, P, K and Mg starvation whereas the symptoms, were manifested on the younger growth due to deficiency of Ca, S, Fe, Mn, Cu, Zn and B. General yellowing of the older leaves and early defoliation were the symptoms expressed by N-starved plants. Phosphorus stress resulted in small brownish spots to appear on older leaves of clove seedlings which later coalesced to form necrotic patches.
