Abstract:

Field experiments were conducted over three growing seasons to study the response of fruit trees: olive (Olea europea) own rooted cutting; peach (Prunus persica), ‘Montclar’; pear (Pyrus communis); quince rootstock and sweet orange (Citrus sinensis); sour orange rootstock to composting treatments of four types of fresh manures in the tree line. Each manure type; cow, sheep, broiler and layer, was incorporated with the soil six weeks before tree planting during autumn in the first growing season and before bud break in the second growing season. The experiment consisted of three main treatments: composting by covering the tree line by black polyethylene sheets for the whole growing season, retaining the cover for six weeks before planting and the check treatments with black polyethylene sheets all over the growing season. Each main treatment included five subtreatments, which received a different source of manure in 40 cm bands at the rate of 10 kg·m^-2, a non- manure subtreatment were included as control. Tree growth as judged by tree volume and stem diameter was greater in the first and second treatments than that in the third treatment. Response of fruit trees species to composting different manure types varied among fruit tree species. The control treatment in which manure was not added had the lowest values. In addition to its role in improving soil physical and nutritional status, this technique provides a better management of organic matter, minimizes the impacts related to the carelessness in disposing manure and represents an efficient weed management.
