| Popis: | Yam tuber dry rot caused by Scutellonema bradys results in the reduction of tuber quality. Studies were conducted on the effect of intercropping cover crops with yams on nematode damage to tubers. Eleven cover crops were intercropped with yams in pot screen house and field experiments. Plants were inoculated with S. bradys in water suspension in pots and by incorporating infected yam peels into soil around plant roots in field experiments with un-inoculated plants serving as control. The experiments were factorial with six replications per treatment in pot and four in field experiments. In pot experiments, populations of S. bradys recovered from tubers and nematode damage were lower in yam tubers intercropped with Tagetes erecta, Aeschynomene histrix, Stylosanthes guianensis, Mucuna pruriens and Pueraria phaseoloides compared to where no cover crops were intercropped with yams. Conversely, S. bradys populations from pots with Crotalaria ochroleuca, Crotalaria juncea, Centrosema pubescens, Cajanus ... |
