Crop abiotic stresses and nutrition of harvested food crops: A Review of impacts, interventions and their effectiveness
In tandem with the accelerating effects of climate change, efforts to increase agricultural productivity to feed the growing population are still being extensively rolled out in Africa. That notwithstanding, a large population in the continent remains food and nutrition insecure; rendering malnutrition the biggest public health challenge. Coupled with the increased incidences of abiotic stresses, developing countries...

Characterization of Pico Island (Azores) wood-pastures
Wood-pastures are gaining importance in various parts of the planet, either for their role in combating desertification, protecting endemic faunas and flora, or their role in animal welfare or nutritional value in all year round grazing systems. On Pico Island and on other islands in the Azores, farmers have been using tree pastures for a long time, especially in the winter, when there is a shortage of grass and the...

Genetic diversity of rice (Oryza sativa L.) accessions collected from Sudan and IRRI using SSR markers
The assessment of genetic diversity of the traditional rice varieties or landraces is an essential component in germplasm characterization and conservation to identify potential parents. In the present study SSR markers (588 SSR markers) were used for the assessment of genetic diversity and relatedness among 31 rice accessions. These included 18 accessions from Sudan and 13 from IRRI. Among the SSR markers used only 483...

Seed treatment and pre-inoculation of soybean: effect of storage period and agrochemicals on the physiological quality of seed and yield
Industrial seed treatment of soybean [Glycine max (L.) Merr.] has increased over the last years. New technologies have been developed to allow the inoculation procedure, which is traditionally done at the day of sowing, to be performed with the industrial treatment days or even weeks before sowing. Since little is known about the compatibility of agrochemicals and pre-inoculation, the objective of this study was to...

Identification of drought selection indices of common bean (Phaseolus vulgaris L.) genotypes in the Southern Highlands of Tanzania
A study was conducted to evaluate common bean (Phaseolus vulgaris L.) genotypes for drought tolerance in the Southern Highlands of Tanzania. Treatments included 18 genotypes laid out in a 3×18 split plot arranged in randomized complete block design with three replications. The data on yield under water stress and non-water stress treatments were used to calculate indices that can be used for predicting tolerant...

Comparative performance of commonly used portable coffee harvesters
In mountain regions due to the high slopes, the coffee harvest is carried out manually, generating higher production costs. An alternative to reducing these costs is to use portable breakers. The objective of this work was to evaluate the efficiency of portable coffee breakers in coffee harvesting. The experiment was carried out in a field of Catucaí Amarelo 24/137, 3.5 years old. In the study, six types of...

Adjustments for axial and sieves systems of coffee harvesters
During the mechanized harvesting of the coffee, there is a fall of fruits in the order of 10 to 20%. This coffee must be later collected. For that, it is necessary to use harvester adjustments that promote a greater picking efficiency. Therefore, the purpose of this work was to define the best adjustments for the axial and sieves system for coffee harvesters. The experiment was carried out using an axial system...
