Conference Paper 1977

Autor: Hahn, S.K. Lal, R.

Mulching of yam seed beds reduced soil temperature and improved emergence, time of emergence, yield per hill and the total yield of Dioscorea rotundata yams on a sandy soil in Western Nigeria. Comparison of mounds with ridged and flat seed beds showed that these different treatments had no signif...

L'utilisation de paillis dans les lits de plantation reduit la temperature du sol et favorise la levee, Ie temps d'emergence, Ie rendement par poquet et Ie rendement global des ignames Dioscorea rotundata lorsqu'elles sont cultivees en sol sablonneux a I'Quest du Nigeria. Lorsque la comparaison a...

El cubrimiento de almacigos de name redujo la temperatura del suelo y mejore la emergencia, el tiempo de emergencia rendimiento por cepa y rendimiento total de name, Dioscorea rotundata, en un suelo arenoso de Nigeria Occidental. La comparacion de camas con almacigos alomados 0 pianos demostr6 qu...

Autor: Hahn, S.K. Howland, A.K. Wilson, J.E.

The constraint to the production of the root and tuber crops, cassava, yams and sweet potato in Nigeria and Africa were stated. Breeding methods most appropriate to these crops were discussed in terms of mating systems, creation of source populations, selection, and use of selections. Intervariet...

Autor: Shiwachi, H. Ayankanmi, T.G. Asiedu, Robert Onjo, M.

A reliable means to induce sprouting in dormant seed tubers of yams (Dioscorea species) is required to enhance flexibility in planting date and rate of propagation of the crop. Experiments were conducted to assess the potential of two gibberellin inhibitors, Uniconazole-P and Prohexadione-calcium...

DNA was extracted from the mycelia of Colletotrichum gloeosporioides[Glomerella cingulata] isolates from yam, and amplification reactions using 11 random primers generated 116 DNA bands, 70 of them being informative. The electrophoretic patterns revealed by these primers allowed the identificatio...

Improving yam production by mineral fertilisation in the savanna zone of Cote d'Ivoire. Côte d'Ivoire is the second producer of yam after Nigeria with 2.8 millions tons produced per year. Though its farmers are still looking for ‘'virgin'' soil to increase their yields. Mineral fertilization stud...
