There were many reports of shoot removal on yield of tuberous in cassava. However very little plant physiology research has been done to verify the cause of such yield reduction. The objective of the study was to investigate the effects of time of first hoot removal on the growth and development ...
Ha diversos resultados sobre a influencia negative da remocao dos rebentos no remindimento das raizes tuberosas da mandioca.noentanto,mutio pouco tem sido feito para verificar as causas dessas reduces no rendimento. O objective deste estudo foi ode investigar o effeito da epoca em que a primeira ...

The effect of time to first shoot removal and the amount of shoots removed on the yield and quality of cassava leaves and tubers were investigated in two experiments carried out at IITA, Nigeria using two cassava varieties, TMS 30572 and TMS 91934. Four different times to first shoot removal, 8, ...

The critical period of weed interference was investigated from 1982–1985 In two local cassava cultivars in Cameroon. Unweeded plots had more than 90% losses and were infested by birds and rodents which caused much damage to the fresh storage roots. One weeding round was not an effective treatment...
The response of yam (Dioscorea) cultivars to artificial and natural infections with minisett rot pathogens was investigated. None of the 20 yam cultivars were resistant to Sclerotium rolfsii [Corticium rolfsii] or Trichoderma longibrachyatum. Cultivars TDa 84/093, 85/236, 85/257, TDr 608, 745, 81...

Interspecific crosses of five cultivated cassava varieties (2n=36) were made with two related Manihot species, M. epruinosa (2n=36) and M. glaziovii (2n=36). From these diploid interspecific crosses, four spontaneous tetraploids (2n=4x=72) and two triploids (2n=3x=54) were isolated for the first ...

One suspected mutant with the broad, thick and dark green leaves characteristic of tetraploid cassava was found from each of the cassava clones TMS 91934 and TMS 89/00037-17 planted out in the field. Cytological examination confirmed them as tetraploids with chromosomes number 2n=4x=72. The mutan...
An automated enzymic method for the analysis of cyanide in cassava and cassava products is described. A total of 300 analyses a day can be handled easily. A wide range of free (nonglycosidic) or bound (cyano‐substituted glycosides) cyanides (0.4–40 μg HCN ml−1) can be assayed in the extracted sol...
