| Abstract:
An experiment was carried out during the 2006/2007 season, under plastic-house conditions at a Station of Princess Tasneem Bent Ghazi for Technological Research in Humrat Al-Sahen; about 25 km from As Salt-Jordan, to compare the effect of four fermented organic matter sources (cattle, poultry and sheep manure in addition to 1:1:1 mixture of the three organic matter sources) in which 4 kg organic matter/m2 were used, compare to conventional fertilizer (chemical fertilizers) and control (no chemical nor organic fertilizers were used) treatments on strawberry cultivar Camaroza by using a randomized complete block design (RCBD) with four replicates. The results indicated that strawberry fruit produced conventionally had higher size and moisture content than the control and organically produced fruit, while the organic source treatments produced fruit with better color, higher dry matter, total phenols, crude fibre and carotene contents as compared to those produced by the control or conventional treatments. Although there was no significance, the conventionally produced fruit had higher total titratable acidity (TTA) percentage than all other treatments. Also the organic source treatments produced fruit with higher total soluble solids (TSS) percentage and ascorbic acid content than with the conventional or the control treatments. In most cases, best results were obtained from the mixture and/or sheep organic matter source treatments. | |
