“…Generally, legume plants have high nitrogen contents in their tissues, resulting in significant N contribution for the soil-plant system after cover crops were cut (CASTRO et al, 2004;OGOKE et al, 2009). Besides, legume plants may improve both nitrogen fertilization and decrease of nitrogen losses in the soil-plant system, also promoting the improvement of soil fertility (CARVALHO et al, 2004).…”

“…The adoption of soil and environmental conservative practices, such as the use of cover crops, play an important role on the establishment of the agrosystem sustainability. However that practice would only be acceptable if the use of such crops favor density and diversity of soil microorganisms, which promote nutrients cycling, contributing specially to the two soil N and P balance (OGOKE et al, 2009). Moreover, cover plants may improve soil structure (CARVALHO et al 2004) and reduce infestation by spontaneous plants in various crops (PARTELLI et al, 2010).…”

Notwithstanding its relevance, studies regarding nutrient cycling and biological dinitrogen fixation in Conilon coffee (Coffee canephora cv. Conilon) associated with cover plants are very scarce. Aiming to evaluate the contribution of cover crops for organic conilon production, a field experiment was carried out consisting of Pennisetum glaucum, and legume species Canavalia ensiformis, Mucuna deeringiana and Cajanus cajan (inoculated and non inoculated) cultivated between coffee trees, and spontaneous vegetation as cover crops. The experiment was carried out in Espírito Santo State-Brazil, in a 6.5 years old coffee crop production system. Chemical analyses of soil and vegetative parts of spontaneous and cover crops, as well as coffee leaf nutrients concentration were performed. Biological Nitrogen Fixation (BNF) was determined by the natural abundance method. BNF contributed with about 80% of the nitrogen accumulated by the leguminous plants, corresponding to 27 -35 kg of N ha -1 . Concentration and accumulation of nutrients varied among cover crops. Rhizobium inoculation did not influence nutrient cycling or BNF. Legume plants partially supplied the nitrogen requirements of Conilon coffee. No significant effect of the treatments was observed on the nutrient concentration of Conilon coffee or on plant growth.

“…Diversification of crop species-especially with legumes and vegetables-reduces risk and prevents malnutrition (Hoeschle-Zeledon and Jaenicke, 2007;Ogoke et al, 2009;Keatinge et al, 2011, Mayes et al, 2012. Most of the underutilized crops are strongly linked to tradition and cultural knowledge and are adapted to specific niches, with short supply and sparse documentation (Hoeschle-Zeledon and Jaenicke, 2007).…”

“…Most such practices involve the use of organic inputs to improve soil fertility and are reported to eliminate the need for fallow periods, increase productivity and maintain soil fertility. According to Ogoke et al (2009) the use of organic inputs is usually the only viable options for small scale farmers without access to chemical fertilizers, which are also believed to contribute to the rapid degradation of the fertility of soils when used in large quantities.…”

Effects of organic inputs (OIs) on maize grain yield and chemical properties of Ultisols were assessed at Msekera and Misamfu Agricultural Research Stations in the medium and high rainfall regions respectively of Zambia. The OIs included biomasses of the leguminous species Cajanus cajan, Tephrosia vogelii, and Crotalaria juncea, in-situ composted native grasses and shrubs called fundikila, modified fundikila using Mucuna pruriens, and composted cattle manure, with chemical fertilizer as a control. After two crop growing seasons, cattle manure significantly increased soil pH, while modified fundikila significantly increased levels of soil organic matter. At Msekera, OIs increased levels of total N by 300%. At Misamfu, fundikila and Cajanas cajan increased total N by 35%. The OIs did not significantly increase available P and K at both sites. In the first season at Msekera, OIs had a higher mean maize yield (6075±368 kg/ha) than chemical fertilizer (3567±715 kg/ha). Maize yields for OIs in the second season did not differ significantly from those of the first season. At Misamfu the leguminous OIs Cajanas cajan and Tephrosia vogelii, had a lower combined mean maize yield (5405±242 kg/ha) than chemical fertilizer (7426±430 kg/ha) in the first season. A 70% decline in maize yield occurred on plots with leguminous OIs in the second season compared to the first season. Leguminous OIs generally performed better at Msekera than at Misamfu. At both sites, the traditional OIs, cow manure at Msekera, and fundikila at Misamfu had higher maize yields than leguminous OIs. We concluded that effects of OIs on soil chemical properties and maize yield vary with soil and climatic conditions and that these need to be considered when selecting OIs for use by farmers.
