“…Mucuna cover crop increases the amount of biomass in the soil during their life time [29]. Biomass production in the soil varies with cover crop species [30] and this could have contributed to the observed variation in soil moisture storage. The continuous use of cover cropping systems added biomass in the soil with time, and this contributed to the reduction of soil bulk density in clay soils, improved soil structure and increased soil porosity [31,32].…”

Inadequate rain is a major hindrance to soil moisture and crop root growth in arid and semi-arid areas of Kenya. A field study was conducted in Ganda, Vitengeni and Matuga locations within the coastal lowland region of Kenya from May, 2012 to April, 2015 to evaluate the effects of three leguminous cover crops on soil moisture retention and orange tree feeder root distribution. Treatments included mucuna (Mucuna pruriens), cowpea (Vigna unguiculata), dolichos (Lablab purpureus) cover crops and unplowed fallow of natural vegetation as a control. The experiment was laid out in randomized complete block design (RCBD) and each treatment was replicated four times. Data collected were: soil particle size distribution, soil moisture content and orange dry root density. The data collected was subjected to analysis of variance (ANOVA) using procedures of R statistical analysis version 3.3.2. Mean separation was done using the least significant difference (LSD) value at 5% level of significance. Results indicated that mucuna, dolichos and cowpea cover crops significantly (P=.05) increased soil moisture content. The mucuna treated plots recorded an Original Research Article

“…ces, cowpea appears to be the dominant crop, and rice the dominated crop. The dominance of cowpea in the intercrop may be due to its phenological attributes; trailing or branching (Abayomi et al, 2001) during the period of growth. This is supported by Sullivan (2001), who noted that in a cereal -legume intercrop, an aggressive climbing bean might pull down rice, maize or sorghum growing with it and lower the grain yield.…”

The increased productivity or yield advantage provided by intercropping is attributed to a better use of resources by crops grown in mixtures, as compared to the same species grown in sole stands. In an intercropping system with upland rice and cowpea, the intra and inter-competition was quantified, as affected by plant population density and rate of nitrogen. Reductions in number of panicles per rice plant and number of grains per panicle were obtained with high density in both sole and mixture rice populations. Increasing nitrogen rate did not affect yield and yield components in both populations, but number and weight of pods per plant of cowpea in sole stands increased. Land equivalent ratios exceeding unity were obtained, indicating an improved resource use by the crop mixture. Relative crowding coefficient and aggressivity indices showed cowpea to be the dominant crop, with rice being dominated. Nitrogen utilization efficiency was high with intercrops, but was generally poor in stands of high population density. Key words: aggressivity index, land equivalent ratio, nitrogen utilization efficiency, relative crowding coefficient COMPETIÇÃO EM UMA CULTURA CONSORCIADA DE ARROZ-GUANDU EM FUNÇÃO DO FERTILIZANTE NITROGENADO E DA DENSIDADE POPULACIONAL DE PLANTASRESUMO: O aumento em produtividade devido a plantios consorciados é atribuído ao melhor uso dos recursos presentes pelas plantas em desenvolvimento conjunto, em comparação às mesmas espécies crescendo em dosséis separados. Em um sistema consorciado de arroz e guandu quantificou-se as inter-e intra competições em relação à densidade populacional e taxa de aplicação de nitrogênio. Reduções significativas do número de panículas por planta de arroz e número de grãos por panícula foram observados para alta densidade, tanto para culturas solteira de arroz como em populações mistas. O aumento das doses de nitrogênio não afetou a produção e os componentes de produção em ambos os sistemas, ao passo que o número e peso de vagens por planta do guandu aumentaram em culturas solteiras. Foram obtidas razões de área equivalente maiores que a unidade, mostrando melhoria no uso da terra nas culturas mistas. O coeficiente relativo de superpopulação e os índices de agressividade mostraram que o guandu é dominante e o arroz dominado. A eficiência do uso de nitrogênio foi alta nas culturas consorciadas, mas em geral baixa para populações de alta densidade. Palavras-chave: índice de agrssividade, razão de área equivalente, eficiência do fertilizante, coeficiente relativo de superpopulação

“…However, the effects of applied materials vary with cropping systems, soil types, organic material management and environmental factors (Kang, 1993;Schroth et al, 1995). Since the 1990s, tropical agricultural research has focused on alternative organic materials (OMs) such as derived from agroforestry and legume cover crops for potential soil fertility replenishment (Palm et al, 1995;Abayomi et al, 2001); the result has been the development of an Organic Resource Database (ORD) (http://www.ciat.cgiar.org/downloads/pdf/ ord_manual.pdf) that mainly uses the quality of OMs to guide the use of organic resources on farms (Palm et al, 2001). However, the effect of OMs on soil is also dependent on other factors such as soil type, management and climate and information on these interactions is scarce.…”

The effect on soil fertility of applying particular organic resources to a humic Nitisol in the central highlands of Kenya was studied. The organic resources (Calliandra calothyrsus, Leucaena trichandra, Tithonia diversifolia, Mucuna pruriens, Crotalaria ochroleuca and cattle manure) were either applied solely or along with inorganic fertilizer in a cropping trial using maize as the experimental crop. After 4 years of continuous cultivation and manuring, soil fertility effects varied among treatments. Cattle manure proved to be the most effective and improved soil fertility by increasing pH, cations (Ca, K and Mg), and C. Calliandra, Leucaena, Tithonia and herbaceous legumes generally reduced soil pH, C and N but increased Ca, K and Mg. Cattle manure is therefore an important resource for maintaining soil organic matter (SOM) in the area and in other similar areas with arable‐livestock systems. Reduction of soil C and N by the high quality organic materials suggests that their role in maintaining SOM in the long‐term is limited in this area. A sound nutrient management system should strive to make a balance between maximizing crop production and sustaining soil quality.
