Abstract: Field experiment was conducted at the Teaching and Research Farm of the Department of Agricultural Technology, Federal Polytechnic Bali, Taraba State in 2018 cropping season with the view to find out the influence of starforce and bentaforce rates on the growth and yield parameters of soybean. The experiment was carried out using split plot design with spacing assign to main plot treatment and herbicides rates as sub plot treatment. The main plot treatments were: 35 x 20 cm, 40 x 25 cm, 45 x 30 cm and 50 x 35 cm and the sub plot treatments were: 0 kg a. i. /ha, 4 kg a. i. /ha, 6 kg a. i. /ha and 8 kg a. i. /ha replicated four times. Result obtained showed that herbicides rates of 6 and 8 kg a. i. /ha performed better in all the parameters measured during the experiment. This was because the rates control weeds better allowing plants to use growth resources without competition. When plants were well spaced and weeded free, there will be no competition between to plants and weeds. All the parameters measured performed better at higher dose indicating that the dose were optimum dose for weed control in Bali. Therefore, considering the optimum rates in this research, farmers should adopt 6-8 kg a. i. /ha of post-emergence herbicides (starforce and bentaforce) for weed control in Bali that leads to higher growth of soybean plant and subsequently leading higher yields.
Keywords: growth, yield, parameters, starforce and bentaforce.
