COMBINED VALORIZATION OF SOLID AND LIQUID AVICOLOUS DIGESTATS FOR THE PRODUCTION ABOVEGROUND OF TOMATO PLANTS IN TUNISIA
Journal Title: Larhyss Journal - Year 2017, Vol 30, Issue 30
Abstract
The use of peat mixed with methacompost of poultry (MCA) with or without incorporation of forestry raw compost (CSB) in the culture substrates has been developed a soilless gardening experiment while using the fertigation at Juice Process Poultry (JPA) diluted 1/150 depending on the report. Growth and wilting tomato plants were, among others, statements. The main results obtained show a favorable germination of tomato seeds leading to almost 100% on mixtures Peat + MCA, growth in the higher height recorded for MCA 10% and inserting a suitable improvement in growth in height mixing plants following the application of diluted JPA (1/150). The partial incorporation of MCA with / without CBS at 10% (SB and SA) allowed to grant quality seedlings eligible and higher than that of SC plants installed on growth (80% + 20% peat MCA) and SC' (60% peat + 20% + 20% MCA CSB) which are far from acceptable in comparison to the imported substrate (peat). The substrate SA (80% peat + 10% + 10% CSB MCA) recorded growth in the largest diameter.
