Weeding Regime Effect on Growth and Yield of forage Lablab Purpureus (L.) In Semi-Arid Sokoto
A field experiment was conducted in 2010 and repeated in 2011 cropping seasons to determine effects of weeding regime on growth and yield of Lablab purpureus. Treatments consisted of a factorial combinations of three intra row spacing (20, 30 and 40cm) and four weeding regime (weedy check, weeding once, weeding twice and weed free) laid out in a Randomized Complete Block Design (RCBD) replicated thrice. Results revealed that in 2010 cropping season Weeding regime showed significance (P < 0.05) in weed dry weight and weed cover score. In 2011 cropping season, Weeding regime influenced (P < 0.05) leaf length at week 9 after sowing, weed dry weight, weed cover score and Crude fiber. Weed dry weight and weed cover score were significant (P < 0.05) in the two years combined analysis. It could be concluded that weeding once produced the highest dry matter yield of 1707.7 and 1711.2 kg/ha respectively.
