Impact of hoe weeding levels on maize and cassava yields in an intercrop
Keywords:
weed control, crop mixture, crop yield, levels of hoe weedingAbstract
Weeds depress yields of crops in mixtures. Intercrops sometimes differ in farm duration and weed management requirements. Maize and cassava vary in their farm duration. Average dry maize grain yields were 3.0 Weed Free (WF) = 3.0 (Hoe-weeded three times) (HW3)> 2.9 Hoe-Weeded two times (HW2)> 2.5 (Weedy check)> 2.3 t/ha (HW1). The average yield of cassava fresh tubers were 33.0 (WF)> 26.1 (HW3)> 22.3 (HW2)> 9.7 (HW1)> 6.3 t/ha (weedy check). One or two hoe-weeding was sufficient for appreciable yield of maize, while the third weeding at nine weeks was more beneficial for cassava than for maize. In a cassava maize mixture, three hoe-weeding is recommended for suitable yield of cassava in the mixture.Weeds depress yields of crops in mixtures.
