Cassava is a staple food and major source of income for many smallholder farmers. However, its yields are less than 6 t ha−1 compared to potential yield 20–25 in Zambia. Understanding cropping practices constraints cassava production systems imperative sustainable intensification. Therefore, survey 40 households each with three fields at 12, 24, 36 months after planting (MAP) was conducted. Ana...

The effect of chronic exposure (35 days) to sub-lethal concentrations of copper (17-212 ppb) and zinc (41-525 ppb) on growth of Farfantepenaeus paulensis postlarvae 17 days old (PL(17)) was analysed. The effects of acute exposure of PL(17) to the same metal on food ingestion and oxygen consumption were also evaluated. Studies were performed using copper and zinc singly, and in a mixture of equi...
