Earliness, Yield, and Fruit Quality Attributes of Low-Chilling Peach-Nectarine Cultivars with The Application of Low Biuret Urea and Calcium Nitrate

This study aimed to determine the effects of low biuret urea and calcium nitrate application on earliness, fruit set, yield, quality characteristics in ‘Astoria’, ‘Maya’ peaches, ‘Garbaja’ nectarine cultivars. In study, Bud Feed (low 15%) (calcium oxide 12% total nitrogen 7%) were applied 35 days before bud break. this flowering harvest times, evaluated. The source temperatures used calculate chill accumulation (expressed as hours below 7°C unit) growing degree was investigated. provided earliness 2 ‘Astoria’ cultivars 3 cultivar. showed positive effect final set all compared control plants. more effective increasing yield per tree by 33.72% (‘Astoria’), 41.00% (‘Maya’), 52.18% (‘Garbaja’). improved size cultivars, whereas intense skin color These results that feed can be prevent losses peach-nectarines warm winter under Mediterranean climate conditions.
