Soil chemical properties under a no-tillage system: Forage grass seeding modes of gender urochloa intercropped with maize

Different farming practices and soil management can make changes in the chemical properties of the soil. In this sense, the monitoring of these possible changes is essential for proper soil correction and/or using systems that are more sustainable. The objective of this work was to verify the behavior of the chemical attributes of a Latosol (Oxisol) under a no-tillage system of plantation, by intercropping maize with...

Influence of environmental factors on carpetgrass seed germination

The aim of this study was to verify the influence of temperature, light, substrate, sowing methods, and salt and water stress on carpetgrass (Axonopus affinis, in the Poaceae family) seed germination. All four trials were performed in a germination chamber under controlled conditions of temperature, moisture and photoperiod. Experimental designs were entirely randomized with 100 seeds per plot. For the study of...

White thread blight disease caused by Marasmiellus scandens (Massee) Dennis & Reid on cocoa and its control in Ghana

White thread blight disease (WTBD) is currently emerging as an important foliar disease on cocoa in Ghana. The disease has been known in the country for many years. Yet, the incidence and severity levels on cocoa in the growing regions are not known. Surveys and sampling were conducted between 2011 and 2013 to estimate incidence and severity of WTBD in the six cocoa growing regions (Ashanti, Brong-Ahafo, Central,...

Adaptability and stability parameters for immature seeds and pods and mature dried seeds in cowpea genotypes in Brazil northeast

The aim of this study was to estimate adaptability and stability parameters in genotypes of cowpea for the yield of immature seeds and pods and mature dried seeds, in order to enable the recommendation of cultivars for the region of São Francisco Submedium valley. We evaluated 30 cowpea genotypes, being fourteen lines of Embrapa Semiarid, six commercial cultivars and 10 landraces in the municipalities of...

Irrigation history and pruning effect on growth and yield of jatropha on a plantation in southeastern Brazil

Jatropha is an oilseed culture that has been highlighted due some specific agronomic aspects. This plant produces high oil quantities in its seeds that is used for biodiesel production. One of the major challenges regarding to the Jatropha cultivation is the lack of information on many management techniques, especially the irrigation and pruning management in adult plants in southeastern Brazil. The objective of this...
