Assessing the impact of different tillage systems and land uses on CO2-C emissions in Eastern Amazonia

The production and emission of CO2 in native, pasture and cultivated areas is a result of microbiological activity and mineralization of organic matter, and depends on favorable environmental factors, such as temperature, availability of water and of land use. The results of this work show that the no tillage system (NT) has the potential to mitigate 37.7% of C-CO2 efflux from cultivation of soy compared to conventional...

Repeatability analysis on morphological descriptors in the early stages of development

The insufficiency of morphological descriptors reveals the importance of studies related to this topic for the genetic improvement of soybean, with attention to the possible descriptors measured in early stages of plant development which allows obtaining fast results. The aim of this work was to estimate the coefficient of repeatability of some morphological descriptors in the early stages of development of...

Evaluation of suitability of tube well water for irrigation in Maiduguri Metropolitan, Borno State, Nigeria

Groundwater contamination is gaining more concerns due to its direct and/or indirect impact on public health. Groundwaters from various sources are commonly used to irrigate vegetables in Maiduguri, Borno State. In this study, the physicochemical qualities of groundwater collected from 20 randomly selected tube wells in Maiduguri were evaluated for their suitability or otherwise for irrigation purposes. Selected wells...

Assessment of factors influencing smallholder farmers’ adoption of mushroom for livelihood diversification in Western Kenya

Poverty is a critical issue in developing countries. It has become almost impossible to carry out any profitable agricultural production as a means of livelihood diversification in areas with small land acreage. Therefore, there is need to identify enterprises that can be incorporated into small holder farmers’ production processes. This study assessed the factors that influence small holder farmers’...

Growth of Jatropha curcas L. plants under salt and nutrition stress

The objective of this study was to evaluate the effects of nutrition and salt stress on the growth and accumulation of mineral elements in Jatropha curcas plants. The work was conducted in greenhouse with 100% solar radiation interception, at Goiás State University, Ipameri Campus, Goiás, Brazil. The experiment was set up in five-liter containers following the completely randomized design in 4 x 2...

Improving geotechnical properties of a sand-clay soil by cement stabilization for base course in forest roads

The study evaluated the chemical stabilization of soils with cement toward application in improving forest roads, as constructive alternative of low cost. The study was carried out with fine soils from the region of Niquelândia-GO, where the sand-clay-silt particle proportion was predominant, and Portland cement CP-II-Z-32 used as a stabilizing agent at 2% under dry soil weight. Geotechnical tests were conducted...
