Abstract

The direct application without composting of the droppings as practiced by the producers does not allow to sufficiently restore the fertility of the soils. The objective of this study was to assessing the effects of manure composting times on soil fertility and lettuce yield. The study was conducted using a Fisher block device. Each block consisted of 6 elementary parcels on which 14, 21, 28 and 35 day chicken manure composts represented by T14, T21, T28, T35, and uncomposted manure TP and control T0 (no manure) were randomly distributed. The contents of major elements (N, P, K), exchangeable bases (Ca2+, Mg2+), cationic exchange capacity (CEC) and trace metal elements (Fe2+, Zn2+, and Pb+) of the composts produced as well as the agronomic parameters of lettuce (average number of leaves, leaf area, crown diameter, total biomass) were evaluated. The T14 treatment resulted in high values of the chemical parameters of the composts and the yields of the lettuce. With a total biomass yield of 371.66 ± 15.46 kg.ha-1, the T14 treatment induced production gains of 244 kg.ha-1 and 52.43 kg.ha-1, respectively, compared to the T0 (no droppings) and TP (uncontaminated droppings) control treatments. The T14 treatment also reduced the levels of trace metal elements in the composts produced. The composting of chicken droppings for 14 days can be advised to market gardeners for production of lettuce at the dose of 40 t.ha-1.
