Abstract
Investigations were carried out at Horticulture Research-cum-Demonstration Farm of the Gujarat Agricultural University, Anand Campus, Anand, during the period of March, 1984 to June 1985 with an objective to find out seasonal variation and accumulation of nutrients in annual growth (Spring flush) and total quantity of different nutrients removed by harvested fruit. The study revealed that almost all macro-nutrients viz., nitrogen, phosphorus, potassium, calcium, magnesium were found to be in optimum range throughout the year and their accumulation steadily increased with age and dry matter accumulation. However, micro-nutrients iron, zinc and manganese were found to be in low level/ deficient level. Therefore, it is suggested that regular foliar feeding of these elements should become a regular orchard operation.
