Abstract
This experiment was conducted as a factorial experiment with randomized complete block design in plastic house of College of Agriculture of Univ. of AL-Anbar during 2011 and 2012 to enhance yield of cucumber grown under organic farming. Four organic substrates prepared from the plants and animal wastes were locally available with foliar spray once or twice after Seedling by 2g/l yeasts extracts .The results indicate that organic substrate prepared from ( 50% corn cobs + 25% poultry manure + 25% cows manure ) with amendments of 2% rock phosphate and 1% Trichoderma fungus inoculate gave better values in plant length, leaves number, leaf area, chlorophyll content ,nods number and plant dry weight. There were 335 cm, 41.07 leaves/plant, 31.84 dcm2, 88.56 Spad values, 41.92 nod/plant and 288 g dry mat., respectively. While, organic substrate amendment with only 1% Trichoderma gave a high yield 4.999 kg per plant compared with control which gave 4.053 kg. On the other hand, foliar spray with yeasts extracts increased plant length, nods number, chlorophyll content, fruit weight and plant yield. Foliar spray twice with mixture of three candida isolates gave high values; 319.9 cm plant lenght, 91.65 Spad values, 38.87 nods/plant and 5.034 kg yield per plant. While, the treatment foliar spray once with S. cerevisia had given larger leaf area was (28.75 dcm2) compared with control which gave 26.14 cm2. Interaction between organic substrate and spray twice by isolates of candida gave better results with most studied proprieties
