“…In this treatment, about 40 % of the total population of cowpea was replanted between 7 and 10 days later. This replanting may have contributed to some extent to the competitive advantage of pearl millet, as indicated by Reddy et al (1992) and . The late planting of cowpea would help pearl millet to overcome the water competition by cowpea.…”

“…However, in environments with such limited water supplies and increased plant density of intercropping systems, competition for the limited soil water may be enhanced. Although the agronomy of the pearl milletbased system has been extensively investigated (Ntare, 1990;Reddy et al, 1992;Craufurd, 2000), only a few studies have dealt with water competition. Most of them focus on pearl millet-tree/shrub interactions.…”

“…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 (Reddy and Willey,1981;Reddy et al 1992). When two or more crops are growing together, each should have adequate space to maximize cooperation and reduce competition between them.…”

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 Sudan, cowpea tops (Vigna unguiculata) have been commercialised as feed supplements for cattle [33]. This legume has also been successfully grown in rotation with Pearl millet in India [15] and a number of cereals in Nigeria [14,29]. Similarly, Sesbania rostrata and Dolichos lablab have been associated with rice, sorghum and millet in Africa [1].…”

Quantitative effects of alfalfa extract supply on rice straw degradation, fermentation and biomass synthesis by rumen microorganisms in vitro

et al. 2001

-In Asia and Africa, rice straw enters into livestock feeds as the main constituent. It is sometimes associated with fresh legume material, from local garden farming or from legume-cereal rotations, but the possible benefits of this practice need to be estimated more precisely, with special attention to the influence of cytoplasmic contents other than nitrogen or macrominerals on rumen microbial metabolism. In the present study, fresh Medicago sativa extract (AE) was chosen as a model of cytoplasmic contents from tops of tropical legumes such as Vigna unguiculata. It was obtained from whole plants harvested at the beginning of flowering (primary growth). The effects of AE supplementation on a rumen microbial community maintained on a diet made of rice straw and inorganic nitrogen (CP: 73.3 g . kg -1 DM) were assessed in dual outflow continuous culture. Three input levels were applied in order to detect curvilinear effects: 0, 0.227 and 0.455 ml . g -1 straw DM. The pH and the redox potential varied from 6.72 to 6.84, and from -335 to -370 mV respectively. The addition of AE had minor effects on fermentation variates. The true degradability of dietary OM and the degradabilities of ash-free NDF and ADF were not modified by AE. Alfalfa extract lowered the outflow of fermented OM (FOM) by 14% while it enhanced the microbial OM outflow (+33%) and the efficiency of microbial protein synthesis (15 to 26 g N . kg -1 FOM). This effect was curvilinear, and appeared negligible above 45-50% of the maximal extract input rate. This legitimised the addition of fresh legume materials to the diet even in small amounts.
