| 1 | Weed control and yield of soybeans (Glycine max (L) Merril) in the Southern Guinea Savanna of Nigeria |
A field experiment was conducted during the 2012 and 2013 rainy season at the Kwara State University Teaching and Research Farm in Malete to evaluate the effect of different weed control methods on weed infestation, growth and yield of soybeans (variety TGX 1448-2E). The experiment consisted of 18 treatments namely, metolachor applied at 1.5, 2.0 and 2.5 kg a.i. ha, pendimethalin at 1.5, 2.0 and 2.5 kg a.i.ha', a tank mixture of metolachlor + diuron at 1.5+0.5,2.0+1.0 and 2.5+1.5 kg a.i.ha", pendimethalin + diuron at 1.5 +0.5, 2.0+ 1.0 and 2.5+1.5 kg a.i.ha", metolachor at 2.0 kg a.i. ha'' plus one supplementary hoe weeding (SHW) at 6 WAS, pendimethalin at 2.0 kg a.i. ha plus supplementary hoe weeding (SHW) at 6WAS, metolachlor + diuron at 1.0 +0.5 kg a.i. ha' plus one SHW, pendimethalin + diuron at 1.5 +0.5 kg a.i. ha 'plus one SHW at 6WAS, weeding at 3 and 6 WAS and a weedy check. All the herbicide treatments significantly reduced weed infestation compared to the weedy check. However, metolachlor + diuron integrated with one SHW was more effective than the application of only herbicides in controlling weeds throughout the crop life. This weed control method also resulted in significantly better growth and higher soybean yield, suggesting that metolachlor + diuron integrated with one SHW at 6WAS is suitable to provide season long weed control in soybean in the Southern Guinea Savanna of Nigeria. | E.O.
