Influence of Living Mulch and Nitrogen Dose on Yield and Fruit Quality Parameters of Malus domestica Borkh. cv. ‘Sampion’

This study was conducted to estimate the yield, and identify quantify primary secondary metabolites in fruit of Malus domestica Borkh. cv. ‘Sampion’ under two agrotechnical factors: floor management (herbicide fallow living mulch) dose nitrogen (50, 80, 110, 140 kg ha−1). Compared herbicide fallow, mulch did not decrease yield. Research showed a rich composition phenolic volatile organic compounds apples, which varied with evaluated factors, as well weather conditions during vegetation season. The precipitation deficit high summer temperatures contribute proper growth development led higher content flesh from trees compared mulch. Living mulch, could be factor regulating availability trees, stimulated synthesis anthocyanins, also potentiated by low average at harvest time, resulting large area skin red blush.
