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

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)

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.

Wider spacing gave higher DM yields/plant, but decreased total DM yields/ha. The proportion of total DM in the...
