<br/><br/> The conventional sprayers, such as the gun sprayers were appliedfor the<br/>apple trees under Egyptian conditions. In organic apple production the<br/>growers tends to apply the compost tea as provide fertili=er and<br/>pesticides control. The objectives ofthis current research were to spray<br/>the compost tea by using the gun sprayer, air assisted backpack sprayer<br/>Stcuki (2.13 kW) and Tia=h. QiniJi Machinery Knapsack. Also,<br/>investigated to use the yeast 'with the compost tea to improve and<br/>increase nutrient availability. The different techniques sprayers an air<br/>assisted backpack sprayer Su=uki (2.13 kW) and Tia=h. Qinili Machinery<br/>Knapsack ,sprayer (0. 7 kW) achieving thorough coverage was compared<br/>to a conventional hydraulic sprayer (gun sprayer) to apply the bio<br/>fertilber compost tea. Two different composts tea, the aerated compost<br/>tea (ACT1) and nun-aerated compost tea (.4CT2), were applied under<br/>laboratory conditions. The 10 gm ofyeast!10 liter was added for both<br/>compost teas (ACT) as the marker ofthe microorganism in the compost<br/>tea. Microscope with digital camera and sofhvare Image J VI.52<br/>program was used to cOllnt the yeasts cells before and after spray<br/>treatment conditions. The conventional hydraulic sprayer (gun sprayer)<br/>gave a good result to apply the compost tea with low values ofnumber of<br/>microorganisms (yeast cells). The low values ofyeasts after treated main<br/>that there are a highest damage or crushed of yeast cells and the<br/>nutrition will be increasing. The viability numbers of yeast cells for<br/>com'entional gun sprayer in ACTJ compost tea were 0.76 x 106 / ml and<br/>0.52 x 1~ / ml at operating pressure 390 kPa and 480 kPa respectively.<br/>As well as. the viability numbers of yeast cells for com'entional gun<br/>sprayer in ACT2 compost tea were 0.84 x 1~ / ml and O. 76 x 106 / ml at<br/>operating pressure 390 /cPa and 480 kPa respectively. he values ofnumber ofyeast cellsfor ACT1 were 0.52 x](1 Iml, 2.60x<br/>106 I ml and 1.22 x 106 I ml for conventional sprayer, motorbed an air<br/>assisted backpack sprayer SU=llki with 2.13 kW power and Tia=h Qinili<br/>MachinelY Knapsack sprayer with 0.7 kW power respectively. The<br/>viability numbers ofyeast cellsfor ACT2were 0.63 x 106<br/>1ml, 1.06 x 1ifI<br/>ml and 0.82 x 106 I mlfor conventional sprayer, motori=ed an air assisted<br/>backpack Su=uki sprayer and Tia=h Qinili MachinelY Knapsack sprayer<br/>respectively. The viability numbers of yeast cells for the air assisted<br/>backpack SlI=uki ~prayer were 2.3 x 106 I ml and 4.6 x 106 I mlfor ACT!<br/>and ACT2 compost tea at halfopen throttle air position respectively. The<br/>conventional gun sprayer produced highly values ofdamage percentage<br/>compared to the T. Qinili sprayer and Su=uki sprayer. The percentage of<br/>damage yeasts cell in ACTl were 97.25% and 96.08 % at operating<br/>pressure 480 /cPa and 390 kPa respectively
