Why is adoption of agroforestry stymied in Zambia? Perspectives from the ground-up
Small-scale farmers in Zambia are faced with problems of low crop productivity, scarcity of fuel wood and fodder, and subsequently are generally food insecure. Agroforestry can contribute to food and income security, amelioration of the environment and subsequently, to mitigation of climate change effects. However, despite all the potential of agroforestry technologies and the effort to promote them among smallholder...

Evaporation of soil water based on the quantity and uniformity of crop waste distribution in soil superficies
Plant residues influence the energy balance and water vapor flux on the soil surface. The aim of this research was to quantify the effect of the amounts and distribution of crop mulching on evaporation of soil water. The study was carried out at the Instituto Agronômico do Paraná, located in Londrina City, State of Paraná, Brazil. In experiment 1, soil water evaporation was determined according...

Determining and modeling the physical, thermal and aerodynamic properties of Pinto beans with different water contents
The present study aimed to determine and model the physical (orthogonal axes, circularity, sphericity and apparent specific mass), thermal (thermal conductivity, specific heat and thermal diffusivity) and aerodynamic properties (thermal experimental speed) of beans grains with different water contents. BRS cultivar were used as test crop and properties were investigated with seven water contents (32.9; 28.1; 24.9; 21.9;...

Physical properties of an Oxisol under different planting and management systems
The changes of soil physical and mechanical properties, arising from the traffic of machines in farming operations, have been widely studied, emphasizing the negative effects of soil compaction on crop productivity. The objective was to evaluate the physical properties of an Oxisol under different planting and management systems. A completely randomized design one-way was adopted for the collection of soil samples. The...

Sweet potato cultivars grown and harvested at different times in semiarid Brazil
Sweet potato constitutes a source of energy and nutrient which is very important economically, especially, for the poorest people in the world, supplies calories, vitamins and minerals in the diet. The determination of the harvest age has great influence on vegetative production, quality, productivity and root biomass. The planting season is determined by climatic elements, which have influence on the growth,...

Effect of different container volumes and concentration of the controlled release fertilizer in the production of Eugenia involucrata DC. seedlings
Eugenia involucrata DC. (Myrtaceae) stands out by its ecological potential, and it is indicated in planting in degraded areas and permanent preserved areas. Because of its importance, the work aimed to evaluate the effect of different container volumes and concentrations of controlled release fertilizer (CRF) in the seedlings emergence and the seedlings growth of E. involucrata in nursery. The experiment was conducted...

Improved production systems for common bean on Phaeozem soil in South-Central Uganda
Common bean (Phaseolus vulgaris L.) is the most important grain legume in Uganda. Beans managed under conventional systems range in yield from 500 to 800 kg ha-1, with a yield gap of about 75%. The objective of this study was to compare the productivity and net profitability of four bean cultivars grown under three management systems on Phaeozem soil (Mollisol) in Masaka District, Uganda. The experimental design was a...

Characteristics of soils under seasonally flooded wetlands (oshanas) in north-central Namibia
Lowland wetlands generally have a high agricultural production potential and can be local hot-spots for biodiversity. Specific seasonal wetland system is largely distributed in north-central Namibia. Seasonal wetlands consist of seasonal river wetlands (locally known as oshanas). However, studies on soil fertility, salinity and sodicity in seasonal river wetlands are still limited in this area. The objective of this...
