One way to obtain high quality pulp production is to improve selectivity delignification of step, maximize yield. Brown pulp yield and chemical composition were studied, with variation of temperature and effective alkali ...

Potassium (K) fertilisation at planting time may not be sufficient to achieve high cassava yields. Experiments were conducted over two growing periods using sweet cassava (SC) variety IAC 576-70 and bitter cassava (BC) ...

Acidity and low P availability in tropical soils constrain cassava (Manihot esculenta Crantz) yield. Liming increases soil Ca and P availability, but Ca can increase the storage root cooking time, and its effects vary with ...

This study aimed to obtain the best dose of waste cooking oil inclusion for the co-digestion of substrates prepared with dairy cattle and swine manure in order to maximize solids reductions and biogas yield. Analyses of ...

One of the problems associated with biomass combustion is the amount of fly ashes generated and its subsequent management. The search for ways of valorizing these ashes has been a challenge for the academic and industrial ...

Common bean has been the main crop in succession to corn and Brachiaria in no-tillage systems, in the Brazilian Savannah. This study aimed to evaluate the influence of crop systems and topdressing nitrogen on grain yield ...

The objective of this work was to evaluate the effect of top-dressed nitrogen fertilization and of the straws of corn crop, of corn intercropped with Brachiaria, and of Brachiaria on grain yield and quality of common bean. ...
