“…Many values have been combined to provide a range, consistent with the approach used for high-chill stonefruit. The current survey produced a narrower range of adequate leaf nutrient concentrations for low-chill stonefruit than for high-chill stonefruit (Leece et al 1971). The concentrations of N, K, S, Cu, Zn, Na and Cl for low-chill were generally within the high-chill range.…”

“…There are no previously published data for low-chill stonefruit representing diagnostic levels apart from tentative values for Florida presented by Crocker and Williamson (1993). The high-chill leaf nutrient surveys were not designed to enable state, cultivar and stage of sampling effects to be tested (Leece et al 1971;Leece and Gilmore 1974;Leece and Barkus 1974), in contrast to the present study, and therefore ranges of values were presented for lowchill stonefruit as diagnostic adequate standards to cover all main effects. We have presented single values (± confidence interval) where significant state or cultivar effects were present.…”

“…The diagnostic leaf analysis standards developed for high-chill stonefruit are based on a review of 39 published nutrition studies with slight modification following a 2 year survey by Leece et al (1971). There are no previously published data for low-chill stonefruit representing diagnostic levels apart from tentative values for Florida presented by Crocker and Williamson (1993).…”

“…Cultivar effects (P<0.05) occurred for many leaf nutrients, however, at the 2-week postharvest sampling, concentrations were sufficiently similar to combine as a narrow adequate concentration range for both cultivars. The diagnostic adequate leaf nutrient concentrations were within the range developed for high-chill peaches (Leece et al 1971) with the exception of lower Ca, lower Mg for New South Wales (both cultivars), lower iron for Flordaprince (both states), higher P for Flordaprince in New South Wales and higher manganese values for Queensland (both cultivars).…”

Summary. A leaf nutrient survey was conducted of the low-chill peach cultivars, Flordaprince (October maturing) and Flordagold (mid November–early December maturing) at 3 commercial sites in both northern New South Wales and southern Queensland. Recently mature leaves from the middle third of a current season’s fruiting lateral (spring flush) were sampled at stone hardening and 2-weeks postharvest and of a non-fruiting lateral at maturity of the summer flush (after summer pruning) during the 1992–93 and 1993–94 seasons. At an additional site in New South Wales (Alstonville), leaf nutrient concentrations were also determined on cv. Flordagem (early November maturing) at 2-week intervals during both seasons. Soil (0–30 cm) chemical determinations were conducted at all sites at 2-weeks postharvest Seasonal trends in leaf nutrient composition were associated with a leaf age–maturity effect. As flush leaves matured during spring, and as mature leaves aged after hardening of the summer flush, nitrogen (N) concentration declined and calcium (Ca) concentration increased. Nitrogen and Ca concentrations increased when young leaves produced from the summer flush were sampled. Time of sampling produced the most consistently significant (P<0.05) main effects on leaf nutrient concentration. The 2-week postharvest period was selected as a convenient time to sample—when leaves were of a consistent age and maturity, and the effect of crop load on tree nutrient reserves was still present. Paclobutrazol, which reduces vegetative growth in stonefruit, was applied to all Queensland sites and, as a consequence, mid lateral leaves contained higher (P<0.05) Ca, magnesium (Mg) and chloride (Cl) and lower (P<0.05) N and phosphorus (P) concentrations than leaves from New South Wales sites. State effects can therefore be interpreted as paclobutrazol effects. Cultivar effects (P<0.05) occurred for many leaf nutrients, however, at the 2-week postharvest sampling, concentrations were sufficiently similar to combine as a narrow adequate concentration range for both cultivars. The diagnostic adequate leaf nutrient concentrations were within the range developed for high-chill peaches (Leece et al. 1971) with the exception of lower Ca, lower Mg for New South Wales (both cultivars), lower iron for Flordaprince (both states), higher P for Flordaprince in New South Wales and higher manganese values for Queensland (both cultivars). Regression analyses were conducted between leaf and fruit nutrient concentrations and soil chemical properties. The only consistent result demonstrated that as the soil Ca : Mg ratio increased, leaf Mg concentration decreased exponentially (P<0.001), indicating that the practice of heavy annual agricultural limestone or gypsum applications in the absence of Mg fertiliser, which had been adopted by several growers in the survey, is associated with lower leaf Mg concentrations.

“…The leaves content in N t (%) at 10-12 weeks after flowering varied between 3.01 % Nt for 'Late Luka'and 3.39% Nt for 'Rubirich' variety in 2010. The values obtained were placed in the normal supply (3.0 to 3.5% Nt) compared with the limits cited in literature (Davidescu and Davidescu, 1992;Leece et al, 1971;Robinson et al, 1997cited by Johnson, 2008Weir and Cresswell, 1993).…”

The present study presents the effect of two organo-mineral fertilizers: root fertilizer C011 and foliar fertilizer 411 bio-ionic liquids,Â on some vegetative and productive features of five new peach [Prunus persica (L.) Batsch] varieties introduced in Romania: â€˜Earlirichâ€™,Â â€˜Royal Estateâ€™, â€˜Rubirichâ€™, â€˜October Starâ€™ and â€˜Late Lukaâ€™, grafted on GF 677 rootstock. The experimental plot located on a reddishÂ preluvosol, have been established in 2008 with four planting systems: Tatura trellis, V planting system, Sibari Y and Vertical axe withÂ different nutrition area/tree. Fertilization was applied on the beggining of June and August, 2010 and 2011 on the soil, locally on the treeÂ rows (C011) and by foliar spraying (411). Trees vegetative growth was compared at the end of the vegetation period by number of fruitÂ buds per unit trunk surface section (CM/TSS) with significant differences between types of crowns and the biggest values for â€˜Rubirichâ€™;Â the total shoots length with significant differences between varieties. The influence of fertilization on trees productivity was apreciatedÂ by analyzing the yield and some typical productivy indexes. The studied parameters including the NPK uptake, have been significantlyÂ influenced by the variety 3.39% Nt at â€˜Rubirichâ€™ in 2010 and 2.75% Nt at â€˜Rubirichâ€™ in 2011 in Tatura trellis planting system.
