Weeds pressure under conventional cassava
Weeds is one of the main constraints for annual crop farming. Like for cassava, after twice plowing (deep and shallow) farmers need to spray 2-3 times herbicides and 1-2 times manual weeding. The weeds population is overwhelming if the drought occurs during the first 2 months.
Use of herbicides for weed management
More degraded the soil is more population of weeds there are. Without any alternatives to reduce costs with same efficiency, farmers use herbicides to control the weeds and for any kinds of annual upland crops (maize, pulse crops, cassava).
Weeds control for conventional cassava
Intensive soil tillage and high dosage of herbicides have not yet solved weeds problem for annual crops farming. For conventional practice for cassava, contact (Paraquat) and/or systematic (Glyphosat) herbicide are used at least twice with at least once manual weeding. The weeds population is increasing while the soil is rapidly degrading under such monocropping of cassava. The problem get even worse with often drought event. So, the cost for weeds control becomes so high, and sometimes the farmers just cancel and fully abandon.
Weeds control for conventional cassava
Intensive soil tillage and high dose of herbicides have not solved weeds problem for annual crops farming. For conventional practices for cassava, herbicides are used at least twice plus one manual weeding. The weeds populations are increasing while the soil is rapidly degraded under such mono-cropping of cassava and maize. The problem get even worse with drought event. So, the cost for weeds control increases, and sometimes the farmers just cancel and abandon their crops.
