The objective of this study was to evaluate the yield, nutritional composition, and digestibility conventional (CON) brown midrib (BMR) pearl millet (PM) with different establishment dates, maturity at harvest when mixed cowpea (CWP). In trial 1, CON BMR were planted on two dates. 2, BMR, or not CWP, harvested PM boot heading stages. dry matter (DM) yield similar between both genotypes but delaying reduced DM by 30%. Additionally, had a lower concentration acid detergent lignin (ADL) higher...

The concentration of urban violence in certain settlements Latin America and the possibility expansion have been latent concerns slum upgrading. This intervention is potentially an peace strategy, especially when it open to local participation promotion capacities for collective action. However, political economy behind upgrading shows that these are settings competence power resources. Different factors (e.g., heterogeneity population size, project design) account bias towards a elite,...
