摘要

在Oyo州Ogbomoso市Ladoke Akintola理工大学教研农场进行了田间试验,以确定尼科隆在木薯地块安全有效施用的最佳时机。采用随机完全区组试验,共设3个重复,6个处理分别为:播种后第3、5、7、9、11周施用除草剂和锄草作为对照。锄草为对照处理。试验结果表明,锄草处理效果最好。各项指标比较差异均有统计学意义(P = 0.05)。较晚处理的植株比较早处理的植株效果更好。在木薯生长早期,尼科隆对木薯有害,但较老的木薯植株可以耐受。

Optimum Time for Safe and Effective Application of Nicosulfuron on Cassava Plot
Field experiment was carried out at the Teaching and Researching Farm of Ladoke Akintola University of Technology, Ogbomoso, Oyo State to establish the optimum time for safe and effective application of Nicosulfuron on cassava plot. There were six treatments namely: herbicide application at 3 WAP, 5 WAP, 7 WAP, 9 WAP, 11 WAP (weeks after planting), and hoe weeding as control in a Randomized complete block experiment with three replicates. The hoe weeding constituted the control treatment. Results of the experiment showed that hoe weeding produced the best response than other treatments. There was a significant difference (P = 0.05) in all parameters measured. The plants treated at advanced age were better than those treated earlier. Nicosulfuron is injurious to cassava at recommended rate in early cassava lives while the older cassava plants can tolerate it.
