The response of Balady lime trees (citrus aruntifollia) to application of inorganic N as well as compost tea enriched with Spirulina plantensis Algae was investigated during 2010 and 2011 seasons.Results revealed that supplying the trees with recommended nitrogen rate (RN) through 75 % inorganic form plus 50 to 200 ml compost tea at 20 % per tree and Spirulina plantensis at 25 ml per tree was preferable more than using inorganic N alone at 75 to 100 %of the recommended rate in improving growth characters, nutritional status of the trees as well as yield, both quantitively and qualitatively of Balady lime trees. Application of compost tea enriched with spiruling plantensis surpassed than using compost tea alone in this respect.Supplying Balady lime trees with RN (800 g/ tree/ year) through 75 % inorganic N + 100 ml compost tea 20 %/ tree + 25 ml spirulina plantensis Algae/ tree is suggested to be beneficial for improving yield and fruit quality. Introduction:Nitrogen fertilization is considered an important and limiting factor for fruiting of citrus crops

The effect of ethanol extracted propolis (EEP) on storage of Red Roomy grapes under low temperature was investigated during 2008 and 2009 seasons. Dipping the clusters for 30 mints in EEP at 0 to 5% then dried with air and stored in especial plates at 1-2°C and 90+5% relative humidity resulted in the following main results:All ethanol extracted propolis at 1 to 5% significantly reduced the percentages of the undesirable berries and berry weight loss compared to untreated one (control) during the two experimental seasons.-Treatments with either 4 or 5% EEP gained the best results, where it caused a significant decreases in undesirable berries percentage by (65.54 & 66.88%) and (63.07 & 63.73%) and berry weight loss percentage (60.08 & 63.68%) and (46.36 & 47.63%) compared to control in both seasons, respectively.-All treatments with EEP failed to show any significant effects on berry chemical properties compared to control.It could be concluded that treatment with 4% ethanol extracted propolis seemed to be the proper and ideal treatment to prolong cold storage of Red Roomy grapes without great reduction on berry quality because it achieved the lowest figures in fresh weight losses, decay % and total acidity. In addition improved the reducing sugars.
