摘要

在2004年和2005年的种植季,在翁多Adeyemi教育学院的教学和研究农场进行了实地试验,以确定杂草侵染造成的产量损失程度和花园蛋(茄)除草的关键时间。试验采用随机完全区组设计,重复3次,包括2个除草处理系列。在第一个系列中,在移栽后3、6、9和12周,采用手除草法保持地块无杂草,此后杂草丛生直至收获;在第二个系列中,在移栽后3、6、9和12周,杂草丛生直至收获;对照地块要么保持无杂草,要么保持杂草丛生直至收获。杂草侵染不加控制,两年平均产量损失87.13%。在移栽后6-12周内保持杂草丛生与在收获前不除草没有显著差异。另一方面,在移栽后的前12周内,通过手工除草保持作物无杂草,与在此之后任何时间保持作物无杂草相似。拔除杂草的关键期为移栽后3 ~ 6周。

Critical Period for Weed Removal in Garden Egg (Solanum Incanum)
Field experiments were conducted at the Teaching and Research Farm, Adeyemi College of Education, Ondo during the 2004 and 2005 cropping seasons to determine the extent of yield loss due to weed infestation and the critical time for weed removal in garden egg (Solanum incanum). The experiment which was arranged in randomized complete block design and replicated three times consisted of two series of weed removal treatments. In the first series, plots were kept weed free of weeds by hand weeding for, 3, 6, 9 and 12 weeks after transplanting, thereafter left weedy till harvest while in the second series weeds were allowed to infest the plots for 3, 6 , 9 and 12 weeks after transplanting, then kept weedy till harvest, control plots were either kept weed free or left weedy till harvest. Uncontrolled weed infestation resulted to an average yield loss of 87.13% in two years . Keeping the crop weed infested beyond the first 6-12 weeks after transplanting was not significantly different from not weeding at all till harvest. On the other hand, keeping the crop weed free by hand weeding for the first 12 weeks after transplanting was similar to keeping it weed free for any length of time beyond this period. The critical period of weed removal was observed to be 3-6 weeks from transplanting.
