Bisbee Delicious apple trees (Malus domestica Borkh.) on Mailing 26 rootstock, planted in 1979 on an Osoyoos loamy sand were subjected, commencing in 1981, to five different orchard soil management treatments including full ground cover, early season vegetation control, total vegetation control, black plastic mulching and shallow tillage. All ground cover suppression treatments decreased leaf K and increased leaf Mg, leaf N and yield. With the exception of early season vegetation control, all ground cover suppression treatments decreased leaf P although P was adequate for initial growth. Declines in soil solution Ca, Mg, and K concentration, 1980–1983, were observed regardless of soil management method. Key words: Apples, M.26 rootstock, leaf N, P, K, Ca, Mg, fruit yield

Soil temperature was measured from 1981 to 1985 at 0.2- and 1.0-m depths for four soil management treatments which included full ground cover, total vegetation control, shallow tillage and black plastic mulching in a high-density orchard planted to Bisbee Red Delicious (Malus domestica Borkh.) on Mailing 26 rootstock. Ground cover suppression treatments, especially black plastic mulching, increased degree day accumulations above 10 °C in all 5 yr at 0.2-m and in 3 yr at 1.0-m depths relative to full ground cover. However, these treatments also resulted in more extreme temperature fluctuations as characterized by higher summer maximum and lower winter minimum temperatures under black plastic mulching. Despite a potential for more extreme soil temperatures, apple yield was significantly higher under black plastic relative to full ground cover. For these two contrasting temperature treatments, leaf N and Mg concentrations were usually significantly higher under black plastic while leaf P and K were consistently higher and leaf Ca and Zn were occasionally higher under full ground cover. Most of these differences were, with the possible exception of leaf Zn, attributed to the competition for, or recycling of, nutrients by orchard floor vegetation. Mean monthly soil temperatures at the two depths under the four soil management treatments could be predicted by simple linear regression techniques from soil temperature measurements at the Summerland Research Station Meteorological Recording Site.

Young Apple

On two cultivars of young apple trees growing in a permanent pasture, a narrow strip was kept bare with herbicide sprays used either during spring and summer or during the entire year. This increased tree growth, fruit set, fruit yield, and fruit size. Using more nitrogen fertilizer did not compensate for the grass competition and did not increase growth or yield as much as did the herbicide sprays. Most of the applied nitrogen could be accounted for in the increased growth of grass. The herbicide simazine increased tree growth more than other herbicides.

Annual Application

Apple trees were planted into soil from which old apple trees had been removed. Experimental treatments consisted of pre-plant fumigation, annual application of fungicides to the soil and four kinds of soil management. Improved tree growth and increased yield were obtained with soil fumigation and from weed control and mulching. The economics of these operations is discussed.

Peach Trees

The effects of keeping a strip along the tree row bare with herbicide sprays or mulched with weed-free straw were compared with either permanent pasture or cultivation. Peach trees growing in the straw mulched strips from their second year onwards grew bigger, made more growth, and produced twice as many fruit of larger size in their fourth and fifth seasons. Apple trees growing in a 1 1/2 metre wide mulched strip also made more total growth and yielded twice the weight of fruit in their fifth and sixth seasons than trees growing under cultivation. Mean fruit size of the apples from the mulched trees was larger, and the mulched apple trees carried more blossoms following a heavy crop than did the cultivated trees. Growth and fruit bearing of the peach and apple trees in the herbicide treated plots was intermediate between the control and mulch treatments.

Annual Application

Bisbee Delicious apple trees on M.26 (Malus domestica Borkh.) rootstock were planted in 1982 on a neutral pH, loamy-sand soil and were subjected to five soil management-fertilizer regimes until 1989. Orchard floor vegetation control with herbicides was required to maximize tree growth. Annual application of P at 50 kg ha−1 and K at 100 kg ha−1 from 1984 to 1989 increased extractable soil P and K to the 40-cm depth but did not appear to increase tree vigor. Orchard floor vegetation maintained extractable soil Ca and Mg levels compared to vegetation control treatments. Key words: Orchard floor vegetation management, extractable soil P, K, Ca and Mg
