“…In an intercrop system between cereals, beans and peas, there has been increased yield presumably by the transfer of biologically fixed nitrogen from the roots of legume to the root zone of the companion crop (Akyempong et al, 1999, Gold et al, 1999, Ndungu et al, 2003, Reddy and Willey, 1981Nanecke et al,1989). …”

Sustainable agriculture seeks to at least use nature as the model for designing agricultural systems. Since nature integrates her plants and animals into diverse landscape, a major tenet of sustainable agriculture is efficiency and lack of waste products in nature. When domestication of crops replaced hunting and gathering of food, landscape changed accordingly. By producing a limited selection of crop plants and animals, human kind has substantially reduced the level of biological diversity over much of the earth. There is more cooperation in nature than competition. Cooperation is exemplified by mutually beneficial relationships that occur between species within communities. If left undistributed and unplanted an abandoned crop field will first be colonized by just a few species of organisms but after several years a complex community made up of many wild species develops. Stability is reached by a community when it has reached a high level of diversity. Diverse communities have fewer fluctuations in numbers of a given species and are stable. The practices which promote diversity and stability on the farm are enterprise diversification, crop rotation, use of wind breaks, provision of more habitats for microorganisms, intercropping and integration of crop farming with livestock production. Intercropping is the cultivation of two or more crops at the same time in the same field. Its advantages are risk minimization, increased income and food security, reduction of soil erosion and pest and disease control. This paper discusses the practice of intercropping in horticultural crop production to promote sustainability. Many crop systems are discussed.

“…In the central region of Uganda, banana is the traditional staple crop and has been grown for hundreds of years (Bagamba et al 2008). Over the last three decades, banana production in the central regions of Uganda has declined, whereas banana production has expanded considerably in the southwestern regions (Gold et al 2000;Rietveld and Farnworth 2018). The major reasons behind the decline in banana production in central regions identified by farmers were reduced labor availability and management, an increase in pest pressure (banana weevils) and declining soil fertility (Gold et al 1999).…”

“…Initially, the banana weevil {Cosmopolites sordidus Germar) was viewed as the main cause for the toppling (see Price, 2006), but in fact it is more responsible for snapping of stems, weakened at or near the base from weevil tunneling (Gold et al, 2001). Towards the end of the 1960s, the burrowing nematode Radopholus similis (Cobb) Thorne, was confirmed in Uganda (Bock, 1969) and implicated in the decline in banana yields (Anon., 1970;Gold et al, 2000). The central region of Uganda was the most heavily infected with the nematode (Patel, 1970), where cooking banana production fell from approximately 18% of the total food crop in the 1970s to 4% in the 1990s (Gold et al, 2000).…”

Radopholus similis is responsible for huge production losses of banana in Uganda, where a large proportion of the population are reliant on cooking banana as their main staple crop. Assessment of the pathogenic and genetic variability of seven populations of R. similis originating from banana plantations in Uganda demonstrated that their virulence on Musa cultivars differed, displaying pathotype-Hke variation. Using RAPD and AFLP techniques the populations could be grouped into two putative genomic groups, which corresponded with R. similis relative pathogenicity. Most, but not all, populations were able to reproduce and damage roots on the two widely confirmed sources of resistance, Yangambi km5 and Pisang Jari Buaya. Studies using RAPD techniques furthermore revealed putative markers for nematode virulence. Variation in virulence of R. similis populations was also demonstrated at the regional (Africa) level. Phylogenetic analysis most closely associated the Uganda populations with populations from Sri Lanka, indicating their likely source of origin. However, genetic variability between Uganda populations also indicate that R. similis was probably introduced into Uganda on separate occasions from different sources, which may help to explain the causes of variability in banana dechne in Uganda. The results of this study have clear implications for the development and deployment of sustainable nematode management practices based on the use of resistance, which could help underpin ongoing management initiatives.
