Seasonal Variation of Nutrients and Nutrient Rations in Apricot Leaves
Abstract
The best method for determining the nutritional
status of fruit orchards is leaf analysis. Nutrient levels of plant tissues
reflect the nutrient uptake of plants in the most accurate way. This study was conducted
on 12 years old "İsmail Ağa" apricot cultivar grafted on
“Apricot Seedling” rootstock at Egirdir Fruit
Research Institute, Isparta-Turkey. In every couple of weeks
as regular, leaf samples were collected at 15
different stages from starting full bloom to lasting until the end of the
season. Nutrient contents of leaf were determined and the seasonal changes of
nutrients and the rations between nutrients were investigated. In leaves, N, P,
Cu, Mn and Zn showed a rapid decrease until mid-season. In the following
periods, while N decreased and P increased slightly. Cu, Mn and Zn remained
stable until the end of the season. While Ca increased until at the end of
vegetation, K and B showed initially an increasing change until mid-season,
subsequently a decreasing change. Mg showed a rapid increase in the first 3
periods but decreased in the following periods. Fe didn’t changed throughout
the season. The rations of N:P, N:K, N:Ca, N:Mg, K:P, K:Ca, K:Mg, P:Zn,
Ca:B, K:B in leaf were respectively and averagely 3.49-11.58,
0.49-1.97, 0.61-7.18, 3.96-12.94, 3.12-17.40, 1.07-3.64, 5.54-10.73, 80-523,
210-788, 687-989.
