This document, Agriculture for Standard Six - Unit 15, focuses on the essential practice of weeding in groundnut and cassava cultivation. It emphasizes the optimal timing for weeding, recommending it at the early stages of crop growth to avoid disturbing developing roots. The unit outlines various weeding methods, including the use of hoes, ploughing, manual hand-weeding, and chemical applications. It also identifies common weeds that affect groundnut and cassava crops, such as blackjack (chisoso), msonthi, amaranthus (bonongwe), luba, tares (namsongole), dawe, khovani, chilungumwamba, denje, likodza, kalasawene, and volunteer crops like maize, millet, and sorghum. Furthermore, the document details the significant negative effects of weeds on these crops, including competition for vital resources like nutrients, water, and sunlight. Weeds also contribute to the transmission of diseases and provide habitats for pests, underscoring the importance of effective weed management for successful crop yields. The initiative 'Jump-Starting Digital Learning in Malawi' by Knowledge and Information for Successful Society makes this resource available to facilitate continued learning, especially for rural students, by providing access to educational materials in the absence of teachers and during disruptions like pandemics or disasters.
