چکیده
Japanese plum (Prunus salicina) farming in the Western Cape (South Africa) is an important industry for export market and job creation a large water user; however, adequate information on requirements of this crop not available semi-arid area. The objective study was to determine seasonal purpose use planning allocation. made experimental data from four fully bearing, high-yielding orchards (cv African Delight Fortune) two major production regions (Robertson Wellington). Crop soil balance were modelled with physically based HYDRUS-2D model. Seasonal estimated be between 524 mm Fortune Wellington) 864 Robertson). Initial basal coefficients (Kcb) ranged 0.98 1.01, whilst Kcb mid-stage averaged 1.11 Robertson) 1.18 Modelling scenarios indicated that redistribution beyond root zone continues at reduced rates after dries levels below field capacity. Irrigation management needs balanced other practices reduce leaching impacts resource quality, as well economics farm.

Pollinizer Influence on Fruit Quality Traits in Japanese Plum (Prunus salicina Lindl.)
Most Japanese plum-type cultivars are self-incompatible and therefore cross pollination is necessary to ensure fruit set. Moreover, pollen can directly affect fruit development process and quality. This study was carried out to investigate the effect of 6 pollen sources (‘Goje Sabz’, ‘Simka’, ‘Shablon’, ‘Methley’, ‘Myrobalan’ and ‘Black Star’) on fruit quantitative and qualitative characteris...
