A study of growth and development of plants of yam beans (Pachyrhizus erosus (L.) Urban) in association with a cultivar of cassava (Manihot esculenta Crantz)


, : A study of growth and development of plants of yam beans (Pachyrhizus erosus (L.) Urban) in association with a cultivar of cassava (Manihot esculenta Crantz). Proceedings of the 2nd International Symposium on Tuberous Legumes, Celaya, Guanajuato, Mexico, 5-8 August 1996: 205-219

In a field study at Turrialba, Costa Rica, yam beans (P. erosus) EC041 and EC509 were grown in pure stands or intercropped with cassava. Increases in fresh and dry weight of the tuberous roots were larger in a pure stand than when intercropped, giving a maximum difference between systems at 90-135 days after sowing. Shade from the cassava plants had a negative effect on the growth and development of yam beans, especially on the neighbouring ridges.

Urban) in association with a cultivar of cassava (Manihot esculenta Crantz). Yam beans (P. erosus) cv. EC509 and EC041 were grown alone or intercropped with cassava in a field trial at Turrialba, Costa Rica. The weight of large and medium sized tubers and total number of roots was significantly greater in the pure stand. T...
