Genga A

Rice Weeding is the most laborious of all the operations. The rice crops is usually weeded twice depending on weed population. The first Rice Weeding is done 3-4 weeks after germination and the second Rice Weeding just before booting. However, most farmers weed only once because of scarcity of labour and other cultivation commitments. The Rice Weeding is normally done with small hoes, adzes or knives. Sometimes, weeds are removed by hand. Rice Weeding is normally done by women.
