Abstract:
... In seeking effective methods to prevent soil degradation, conservation tillage plays an important protective role. Apart from significantly reducing production costs, cover crops contributes to beneficial changes in the soil environment. A three-year field experiment included three cover crops (winter rye, winter oilseed rape, and white mustard) subjected to mulching or desiccation and to the acti ...

Abstract:
... To develop better mechanical management strategies, more information on the impact of root partitioning on changes in the population dynamics of Sonchus arvensis is needed. Therefore, the effects of root fragmentation of S. arvensis on shoot height frequency distributions, biomass production and nitrogen allocation were studied in an outdoor experiment in Sweden in 2008. Three artificial populatio ...

Abstract:
... Tomato is an important vegetable widely grown in the tropics due to its nutritional value and financial benefits for farmers. In Ghana, there is an undersupply caused by production ceasing entirely from October to May due to high temperatures. Heat stress has been reported to cause excessive flower drop leading to drastic reduction in yield; however, genotypic differences in heat tolerance exist i ...

Abstract:
... The potential of bambara groundnut as a crop-based approach for the sustainable reduction of protein–energy malnutrition prevalent in Nigeria is still being explored. However, one of the limitations to sustainable production of this adapted species is low and unstable yield. Here, we employed multiple statistical analyses to determine traits that could be useful in predicting grain yield. Furtherm ...

Verdcourt, viz. bambara groundnut – a species with underground pod setting – by subsistence farmers throughout Africa. This agricultural practice consists of bringing soil to the crown of bambara groundnut plants and has been shown to improve seed yield of the crop. However, lit ...
