Cropping system, viz, monocropping and intercropping, did not influence the yield and number of marketable, non-marketable and total tubers of cassava and its fresh herbage yield, tuber dry matter content (DM) and apparent harvest index (HI). Tillage method markedly influenced these parameters except the yield and number of non-marketable tubers. Yield and number of marketable and total tubers, herbage yield, tuber DM content and HI increased significantly when tillage was employed regardless of whether it was minimum or conventional. Total mungbean yield and weight of 1000 seeds were unaffected by tillage method. Both cropping and tillage treatments significantly affected the weed dry weights at two and four months after planting (MAP). Regardless of tillage method, intercropping produced appreciably lower weed biomass than monocropping at any time. Weed biomass production decreased consistently with the increase in tillage intensity under both monocropping and intercropping patterns.
