| description | Two trials were conducted at the Federal University of Agriculture, Abeokuta to evaluate the combined effect of early apical bud removal (ABR) and severity of pruning on the performance of pigeon pea. In the field, 7 treatments arranged in Randomized Complete Block Design comprised of stem pruned at 25, 50, or 75 cm above the soil with or without ABR and a control plot. In the screenhouse, 5 pruning regimes (no pruning, 25, 50, 75 and 100 cm above the soil) with or without ABR were arranged in completely randomized design. Both trials were replicated thrice. The ABR was at 5 and 7 WAP (weeks after planting) and pruning was done at 16 and 12 WAP in Experiments 1 and 2 respectively. ABR and pruning led to 37.5 to 62.4 % reduction in grain yield on the field and significantly (p<0.05) increased plant biomass in both trials. Stem girth, dry weight, number of branches, and height at first branching were significantly influenced by pruning severity (p<0.05) in the screenhouse. In both trials, fastest re-growth was recorded from plants pruned to 50 cm (p<0.05). Least value for percentage survival (85 %) was recorded from plants pruned to 25 cm in the field; no mortality was recorded in the screenhouse. It was concluded that early ABR did not stimulate lateral branches closer to the soil surface; pruning to 50 cm above the soil level is still the most adequate that combines high survival rate, biomass production and appreciable grain yield in pigeon pea management. |
