Fruit production is primarily governed by proper cultivar selection. Besides, it is appropriate growing conditions that ensure stable production of high-quality fruits and continuity on the market. Some productive and pomological-technological properties of apple cv ‘Idared’ grown in the region of Čačak (Central Serbia) have been studied. The paper presents two-year results (2006 and 2007) of the study of productivity under the conditions of irrigation, fertigation and without irrigation. The study was performed in commercial plantings of the most prominent fruit growers of this region. Yields ranged from 23.5 t/ha (younger trees) to 110.9 t/ha (trees in full cropping), depending on tree age, planting density, rootstock and applied cultural practices in the commercial plantings. During the first year of study, from early June to late August, 309 mm of rainfall was recorded, and only 99 mm over the second year of study was reported. Therefore, low rainfall and long periods of drought over the growing season without irrigation of plantings resulted in lower yields by some 20 – 40% , as compared to the first year of study. Irrigation and fertigation applied during the first year of study ensured higher yields. The results obtained over the second year of study suggest exceptionally favourable effect of these practices when applied under extremely unfavourable conditions. Growing conditions and applied cultural practices clearly influenced fruit size, soluble solids content and fruit ripeness.
