An experiment was carried out under plastic house conditions 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 m(-2) were used, with that of the conventional agriculture (chemical fertilizers) treatments on Marvello red pepper fruit quality, by using a Randomized Complete Block Design (RCBD) with four replicates. Pepper fruits characteristics cultivated in soil supplemented with manure were generally better than those from plants grown in soil only. Addition of animal manure increased bell pepper fruit content of soluble solids, ascorbic acid, total phenols, crude fibre and intensity of red color as compare with conventional agriculture that produced fruits with higher titratable acidity, water content, lycopene and bigger fruit size. In most cases of animal manure treatments, best results were obtained by the sheep manure treatment that produced the highest TSS, while the worst results were obtained by the poultry manure treatment that produced the smallest fruit and lowest fruit lycopene content.

A greenhouse experiment was carried out during the 2004/2005 season at Abu-Ghannam\'s farm in Kreimeh in the northern Jordan Valley-Jordan, to study the effects of fermented organic matter (made from sheep manure and annual weeds) used at four rates of 1.5, 3.0, 4.5, and 6.0 kg/m 2 in comparison to conventional system (chemical fertilizers and pesticides) on growth, flowering and yield of the strawberry cultivar Honor. A randomized complete block design (RCBD) with four replicates was adopted. The highest vegetative growth (leaves/plant, leaf area, plant fresh and dry weight) was found in the conventional treatment, while the highest root/canopy ratio was obtained by the 4.5 kg /m 2 treatment. Organic matter advanced flowering date, while the conventional treatment delayed it. Runner production was not significantly affected by the type of treatment. The conventional treatment produced the highest fruit weight, total yield per replicate, and total yield per plant.
