“…The quantity and quality (organic N) supplied by the residues of legumes improve soil N, biological properties and availability of other nutrients, leading to better growth and good health for the succeeding sorghum. As reported inprevious work, subsequent cereal yields are usually increased in legume-cereal rotations [3,4,18] as a consequence of mineral N provided by mineralization of legume residues [19][20][21][22] and the improvement of soil biological properties and availability of nutrients [17]. Then, despite the increase of the population of nematodes, the succeeding sorghum benefits from good nutriational conditions and has quicker and better growth, particularly during the first period of the season.…”

The effects of cowpea (Vignaunguiculata) and groundnut (Arachis hypogea) on succeeding sorghum yields, soil mineral N and nematode infestation were studied during five cropping seasons (2000 to 2004) in a weakly acid Ultisol of the agronomy research station of Farakô-Balocated in the Guinean zone of Burkina Faso, West Africa. A factorial 5 × 5 design of five crop rotations with five fertilizer treatments in a split-plot arrangement with four replications was used. Sorghum yields were affected by the two factors (rotation with legumes and fertilizer applications) during the four years. But interactions were not observed between the two factors. Monocropping of sorghum produced the lowest yields and legume-sorghum rotations increased sorghum yields by 50% to 300%. Groundnut-sorghum and cowpea-sorghum rotations increased soil mineral N by 36% and 52%, respectively. Crop rotation influenced nematode infestation but the effects on soil and sorghum root infestation differed according to the rotation. The cowpeasorghum rotation increased soil and sorghum root infestationby nematodes while groundnut-sorghum decreesed the nematode population. The soil of the cowpea-sorghum rotation contained 1.5 to 2 times more nematodes than the soil of the monocropping of sorghum. In contrast, the soil of the groundnut-sorghum rotation contained from 17 to 19 times fewer nematodes than that of themonocropping of sorghum. However, nematode infestation did not affect any of the succeeding sorghum yields. It was concluded that the parasitic effect of nematodes was limited by the predominance of positive N-effects on the development of succeeding sorghum.

“…Despite this decline, however, lablab appears to persist as a garden crop (rather than a field crop) in eastern and southern Africa; and recent market surveys from eastern Africa suggest that there is a high demand (and subsequently a good price) for lablab in Kenya (Ngailo et al 2003). There is almost no ongoing lablab research in Africa, except for programs focusing on improving soil properties by using green-manure/forage crops, such as in maize-based systems of Kenya (Mureithi et al 2003; Cheruiyot et al 2007; Lelei et al 2009), Malawi (Sakala et al 2004) and Nigeria (e.g., Ibewiro et al 2000; Amodu et al 2004; Gbaraneh et al 2004; Rahman and Ogungbile 2006), or sorghum- and millet-based systems in the semi-arid tropics of Mali (Kouyaté et al 2000). Almost all of these African initiatives have included and continue to include one popular late-maturing forage cultivar, cv.…”

In recent years, so-called ‘lost crops’ have been appraised in a number of reviews, among them Lablab purpureus in the context of African vegetable species. This crop cannot truly be considered ‘lost’ because worldwide more than 150 common names are applied to it. Based on a comprehensive literature review, this paper aims to put forward four theses, (i) Lablab is one of the most diverse domesticated legume species and has multiple uses. Although its largest agro-morphological diversity occurs in South Asia, its origin appears to be Africa. (ii) Crop improvement in South Asia is based on limited genetic diversity. (iii) The restricted research and development performed in Africa focuses either on improving forage or soil properties mostly through one popular cultivar, Rongai, while the available diversity of lablab in Africa might be under threat of genetic erosion. (iv) Lablab is better adapted to drought than common beans (Phaseolus vulgaris) or cowpea (Vigna unguiculata), both of which have been preferred to lablab in African agricultural production systems. Lablab might offer comparable opportunities for African agriculture in the view of global change. Its wide potential for adaptation throughout eastern and southern Africa is shown with a GIS (geographic information systems) approach.

“…Weisskopf et al (2009) found out that other factors such as weed suppression could be the main factors that contribute to enhanced yield of cereals in a legume/cereal intercrop. Lower sorghum yields under monocropping have also been previously observed by Kouyaté et al (2000). They attributed this to presence of phenolic compounds in the monocropped fields which resulted in allelopathic effects causing poor germination and stand establishment.…”

In this study, the influence of ecological farming practices on soil moisture and yield of cassava (Manihot esculanta Crantz) and sorghum (Sorghum bicolor (L.) Moench) was investigated. The study was conducted in semi-arid Katangi and Ikombe divisions of Yatta sub-county between October 2010 and August 2012. A randomised complete block design with a split plot arrangement was used. ). Intercropping sorghum with dolichos and cassava with pigeon pea + FYM would be a viable strategy to boost crop yields in smallholder farming systems of Yatta sub-county.
