Conteúdo: | Two yield trials are discussed in this section. The trial in the Molino suffered a low level attack by mites and was defoliated by a droughy, whereas the Fonseca trial was infested to a greater level for a longer period and was well irrigated to avoid the drought induced defoliation. Therefore more emphasis will be put on the Fonseca trial. The Molino trial will only be briefly discussed. These two yield trials were conducted to answer some basic questions about mite resistance. The objectives were to study the relationship between mite populations and foliar mite damage, to study mite population fluctuations on both resistant and usceptible varieties, to determine the effect of a mite attack on plant growth and harvest parameters of mite susceptible and resistant varieties, and to examine several cassava varieties with respect to their leval and types of resistance.
