Effect of some weed control methods on growth and fruiting of (western schley & whichita) pecan cultivars
Abstract: This study was conducted in naturally infested pecan orchard with weeds at Horticulture Research Station, El-Kanater El-Khyria, Qalyobia Governorate during 2007 and 2008 seasons, to study the effect of two cultivars of pecan (Western Schley & Whichita) and five weed control methods (hand hoeing, mulching with black plastic sheets, mulching with banana leaves, Roundup herbicide and unweeded check) on weed control. Growth, fruiting and fruit quality of pecan, in addition to the changes of microbiological populations in the soil. Obtained results indicated that cultivars had no significant effect either on weeds or changes of microbiological populations in the soil. However, Whichita gave was the better cultivar in growth, fruiting and fruit quality than that of Western Schley during 2007 & 2008 seasons. All tested weed control treatments significantly decrease the weeds and increasing growth, fruiting and fruit quality of pecan comparing with unweeded treatment. Glyphosate (Roundup 48 % WSC at a rate of 4 liter/fed.) and mulching with black plastic sheets were superior for controlling weeds, tree growth (area and dry weight of leaflet, shoot length and thickness); nut physical characteristics, i.e., nut and kernel weight, kernel percentage and nut oil content. Results indicated that Roundup foliar application showed higher counts of bacteria, fungi and actinomycetes than that recorded with the other treatments.
