Effect of organic mulch on seed and tuber yield of early season winged bean (Psophocarpus tetragonolobus (L.) DC) at Onne, Nigeria



Effect of organic mulch on seed and tuber yield of early season winged bean (Psophocarpus tetragonolobus (L.) DC) at Onne, Nigeria



African Journal of Agricultural Teacher Education 9(1/2): 65-70



Field experiments were conducted in Nigeria during the rainy season of 1991 on winged bean (Psophocarpus tetragonolobus Tpt 26) to determine the effect of organic mulch on tuber yields. Tuber yields in staked and unstaked winged beans, with or without flowers were also studied. In staked beans with flowers, mulching decreased seed yield by 40% compared with those without mulch. Mulched and staked beans with flowers gave a high tuber yield obtained from similar plants without mulch.
