| 1 | Effect of method of weed control and insecticide (Lambda cyhalothrin) rates on the productivity of cowpea (Vigna unguiculata (L.) walp) in a southern Guinea savanna of Nigeria |
Field trials were conducted in two locations, at the Teaching and Research (T&R) Farm of the College of Agriculture, Kwara State University and Ga-Alanu Village, Malete, in the 2015 cropping season. The objective this work was to evaluate the effect of herbicide application associated to the insecticide Lambda cyhalothrin on weed control, and yield of cowpea. The experiment consisted of 18 treatments arranged in a factorial scheme. The first factor was three insecticide rates (0 ml ha-1, 8.75ga.i.ha-1 and 17.5ga.i. ha-1). The second factor was the six methods of weed control (pendimethalin at 1.5kg a.i ha-1, pendimethalin at 2.0kg a.i ha-1, pendimethalin at 1.5 kg a.i. ha-1 plus one supplementary hoe weeding (SHW), metholachlor + diuron at 1.5 + 0.6 kg a.i ha-1, hoe weeding at 3 and 6 weeks after sowing (WAS) and a weedy check). The treatments were laid out in randomized complete block design arranged factorially with 3 repetitions . Variables measured were weed density, weed dry matter, relative importance value of weed species, plant height, crop vigour, number of pods/plot and grain yield. Data collected was subjected to analysis of variance and means were separated using Least Significant Difference (LSD) at 5% level of probability. Results showed that insecticide rates at 8.75ga.i.ha-1 and 17.5ga.i.ha-1, and pendimethalin at 2.0kg a.i.ha-1 or pendimethialin at 1.5kg a.iha-1 plus one SHW promoted good growth and higher yield of cowpea.
