摘要
Composts are recognised as an important source of nutrients for crops. The study aims to valorise agricultural by-products by composts made from broiler (A), laying hen (B) and bovine (C) manures in soilless tomato cultivation. Treatments consisted of these three composts and controls consisting of coconut fibres fed with a nutrient solution. The system is a randomised Fisher block with three replications. Each elementary plot consisted of nine tomato plants. Chemical parameters of the substrates and agronomic parameters of the plants were recorded from 14 to 49 days after transplanting (DAT). The pH stabilised at around 6.2 after varying from 7.1 to 8.0 in the composts. The high electrical conductivity (5.9 - 6.01 dS/m) was less than 1 dS/m at 49 DAT. Agromorphological parameters were close to the controls. Fruit necrosis was higher in the compost-based substrates (13.75% - 32.22%) than in the controls (<2%). Healthy fruit yields from the composts (38.7 - 48.7 t/ha) were high, although lower than those from the controls (49.9 - 57.4 t/ha). Fruit harvested from these substrates had a longer average shelf life (38.23 days) than the controls (28.5 days). This study showed that composts have fertilising properties for soilless tomato cultivation, in particular that of laying hen manure (48.33 t/ha). These composts could provide an alternative to the use of chemical fertilisers in soilless tomato cultivation.
