to be kept down as they compete with the crop for nutrients,
water and sunlight. If weeds become overgrown they inhibit
the natural chemical process of photosynthesis; if weeding is
not carried out effectively then the productivity of the
Plant will drop substantially. Women play a more significant
role in the work of weeding than men, since this is
traditionally women's work, although men will often help in
this activity. This work is non-mechanical drudgery carried
out by hand. While herbicides have been developed which
control the growth of weeds and they are normally included as
part of the "Green Revolution" technological package, they
are normally only used when labour costs are high. Thus, like
the situation in the majority of peasant based economies,
where farming remains labour intensive, hand labour remains
the main means of controlling weeds, and it must be said hand
labour can achieve the same or even better control of weeds
in most situations. (29) It should be noted that in the
earliest period of the growing season weeds are kept to a
minimum through the use of plastic sheeting which is used to
preserve soil moisture around the plant. This plastic
sheeting has holes from which the commercial plant emerges
and nothing grows directly under the plastic sheeting as the
temperature is so high that it kills leaf-life. Thus, in the
early period the use of plastic sheeting helps to keep down
the growth of weeds. This however only lasts for a short
period of time. Once the plant has grown the sheeting has to
be lifted and the weeds compete with the plant for nutrients,
water and sunlight.
