Abstract

Nowadays, more attention has been paid towards the so called ’clean agriculture’ or organic agriculture. At the same time, the proper strategies of mineral fertilization were putted into consideration. Because the excessive use of high cost chemical fertilizers may cause environmental pollution and deterioration of soil fertility, therefore the application of organic farming concept either alone or in combination with proper strategies of chemical fertilizers could be of interest. Many of organic systems was pointed out such as the recycling of farm wastes i.e. crop residues, animal manure, organic conditioners for reclamation of soil and in the same time enhancement of plant growth and improving yield quality. Changes in plant height were fluctuated according to the combinations between concentrations of organic additives and the recommended rates of mineral fertilizers. In other turn, but generally, the combination between mineral fertilizers and organic additives had enhanced the plant growth that can be recognized as changes in plant height term. Organic substances additions and mineral fertilizers application either individually or in combinations were beneficial in increasing N uptake by fruits. This phenomenon was pronounced at high rate of addition of both of them. There was no significant difference between mineral fertilizer doses. Similar trend was noticed when organic substances accompanied with mineral fertilizers.
