“…Furthermore, increased 1eaf P concentration of microjet-irrigated trees may reflect greater cover crop growth in the irrigated portion of the rooting zone (Neilsen and Hogue, 1985). Other factors which increase the diffusion of P to plant roots, such as high soil moisture content, which might result from high frequency irrigation, have been considered critical for plant P uptake (Neilsen et al, 1990). Irrigation frequency appears to have been important for these Pfertigated apples trees only in the first year when trees' root systems were establishing, and root length most limited.…”

`Gala' apple (Malus domestica Borkh) on M.26 rootstock was subjected, in the first five growing seasons, to NP-fertigation and a factorial combination of treatments involving method and frequency of irrigation. Two types of emitters (drip or microjet) were used to apply the same quantity of water at high (daily), intermediate (about weekly) and low (about bi-weekly) irrigation frequencies. Although initial tree vigor and yield were higher for drip-fertigated trees, by the end of the study microjet fertigation produced larger trees of similar yield. These microjet fertigated trees had higher leaf P, K and Cu but lower leaf N, Mg, and Mn than drip-fertigated trees. Soil pH and extractable Mg and K concentrations were higher and extractable-P concentrations lower directly beneath microjet-emitters as a result of the larger fertigated soil volume relative to drip-emitters. High frequency irrigation improved tree growth but had less effect on leaf nutrient concentrations or soil chemical changes than lower frequency irrigation. Leaf N concentration was most affected by irrigation frequency, tending to decrease with daily irrigation.

“…Thus, temperatures as low as 8°C can limit peach growth despite increased P availability, whereas high P availability and high RZT (to 24°C) may predispose peach seedlings to chlorosis problems related to inadequate Fe or Zn. Although major differences exist between solution and soil culture with respect to P movement to the root surface, these results indicate that like apple (22), peaches may respond to planting hole P application. However, the response may be temperature-related with little effect in soils as cold as 8°C and a tendency to generate detrimental P-micronutrient antagonisms at high P -high soil temperatures.…”

Siberian C peach seedlings (Prunus persica L. Batsch) were grown for 35 days in all combinations of Long Ashton nutrient solution containing P concentrations of 0.05, 0.5, or 5.0 mM and root zone temperatures (RZT) of 8°C, 16°C, and 24°C. At harvest, a significant interaction between solution P concentration and RZT occurred for shoot and root dry weight, root length, shoot P concentration and shoot P uptake. At 8°C RZT, P concentration and uptake but not growth were increased by P. At 16°C and 24° C RZT, growth was depressed at the 5.0 mM P level with shoot P concentration and uptake lower at 24°C than 16°C. The inflow of P to the peach shoot per unit root length was increased at high P concentration and low temperatures but was lower than whole plant inflow rates for apples. The growth depression at high temperature-high P was related to increased young leaf chlorosis, reduced shoot Fe and a possible P/Zn imbalance. INTRODUCTIONRoot-zone temperature (RZT) can strongly influence root and subsequent shoot development (1) and shoot mineral accumulation including P (2). However, only a few studies (3,4) have investigated the effects of RZT on fruit tree growth and nutrition. Phosphorus nutrition of fruit trees has also received little detailed attention since many early studies indicated few responses to P fertilization (5) and
