Abstract
VC (20%), TC (20%) and N:P:K fertilizer (farmer's practice) were used to determine the growth and yield attributes of bush bean (Phaseolus vulgaris), winged bean (Psophocarpus tetragonolobus) and yard long bean (Vigna unguiculata). Plants grown with VC (20%) produced the highest fresh biomass for bush bean (527.55 g m-2), winged bean (1168.61 g m-2) and yard long bean (409.84 g m-2). In all the tested legumes the highest pod weight, pod number, pod dry weight and pod length were found in the VC (20%) treatment. Photosynthetic rates in the three legumes peaked at pod formation stage in all treatments, with the highest photosynthetic rate observed in winged bean (56.17 µmol m-2s-1) grown with VC (20%). The highest yield for bush bean (2.98 ton ha-1), winged bean (7.28 ton ha-1) and yard long bean (2.22 ton ha-1) were also found in VC (20%) treatment. Furthermore, protein content was highest in bush bean (26.50 g/100g), followed by yard long bean (24.74 g/100g) and winged bean (22.04 g/100g), under VC (20%) treatment. It can be concluded that legumes grown with VC (20%) produced the highest yield and yield attributes.
