Article Synopsis
- The global demand for chocolate has increased the need for high-quality cocoa beans, leading to a study on how different cultivar types (CCN51 and PS1319) and cultivation methods (cabruca and full sun) affect the chemical makeup of unfermented cocoa kernels.
- The study found that the cultivation system affects fatty acid composition, with full sun promoting higher linoleic acid levels, while cabruca resulted in greater total lipid content. Additionally, cultivar type impacted various fatty acid ratios and levels of phenolic compounds, with lower antioxidant properties in the full sun system, especially for PS1319.
- The research concluded that both cultivar and cultivation methods significantly influence the chemical composition of cocoa, suggesting that
The banana tree circle (BTC) is a low-cost system for local greywater management, using a natural treatment and disposal process, providing additional resource recovery benefits. However, there are no standard design criteria for BTC that would allow for quality control of its efficiency and sustainability, and little is currently known about the full-scale performance of BTC. Based on the scoping literature review of 31 documents in the scientific database and eight documents from grey literature, a standard design model was proposed for the BTC technology based on the concept of water balance, greywater flows, rain, infiltration, and evapotranspiration.

Arbuscular mycorrhizal fungi (AMF) are elements which are key to improving crop productivity and soil quality. It is pertinent to understand how agricultural management in the tropics affects the AMF spatio-temporal community composition, especially in crops of global importance, such as coffee (Coffea arabica L.

A field study was carried out in Alegre Espiríto Santo, Brazil, on a Xanthic Ferralsol cultivated with braquiaria (Brachiaria brizantha). The six pasture managements studied were: control (CON), chisel (CHI), fertilizer (FER), burned (BUR), plowing and harrowing (PH), and integrated crop-livestock (iCL).

The adsorption process was dependent on the various operating variables, viz., solution pH, particle size of the vermicompost, mass of vermicompost/volume of the Zn(II) solution ratio, contact time and temperature.
