A traditional practice of fertilizing soils with excreta deposited by cattle in small paddocks at night is used for subsequent cultivation of cassava. However, research information on animal stocking and duration of this fertilization process is lacking. The objective of this work was to determine better combinations of stocking rate and number of nights in which bovines fertilize the soil with their excreta for cassava cultivation in the Brazilian Amazonia using the night paddock manuring system. We correlated stocking rate, number of nights, soil fertility, nutritional status of plants, and tuberous root yield using data collected in commercial cassava cultivation areas. The root yield was not significantly correlated with stocking rate or number of nights. However, when these two factors were combined into a single index that we have denominated index of soil fertilization by cattle, the correlation was significant. The index that resulted in the estimated maximum root yield was calculated to be 225. This value can be achieved with five combinations of stocking rate and number of nights. The intermediate combination consisted of 9 animals in a 100-m2 paddock and 25 nights. This study provides useful information to optimize a traditional practice of soil fertilization for cassava cultivation. |
