摘要：

The experimental work was carried out in the period 2014-2016 in a fruit-bearing peach plantation at the Fruit-Growing Institute Plovdiv, Bulgaria. 'Glohaven' cv. grafted on the vegetative rootstock GF 677 was investigated. Increasing doses of three bioproducts - Biohumus, Agriful and Humustim have been tested. The aim of the experiment was to study the influence of bioproducts on the content of chlorophyll and the main nutrients in the peach leaves. Bioproducts used had a positive effect on the chlorophyll accumulation. The highest total chlorophyll content (a + b) was reported in the variant treated with Biohumus and the differences with the non-fertilized control being statistically significant. Regarding the nutritional status of the trees, the best results were provided by Biohumus 1.8 kg/tree and Agriful 1 L/ha.
