“…Yehia (2008) concluded that the optimal conditions for a packaging machine were: coatingunit speed of 28 rpm, coating temperature of 40 °C, heat exposure time 30 min, Arabic-gum temperature and concentration 50 -110 °C and 25 -75 %, and grain-lot mass 1 -4 kg. Yehia et. al., (2010) found that the maximum fennel, caraway, coriander, nigella, and guar seeds germination of 98.1, 96, 98, 100 and 100 % was obtained with a coating temperature of 40 Co and coating time of 30 min.…”

The aim of this research is to study the variables influencing the mechanical coating of quinoa seeds. These factors are coating speed, temperature and time, and seed lot. The main results in this study can be summarized in the following points, the maximum quinoa-seed germinations of 90.5, 94.3, and 81.4 % by utilizing the covering unit speed of 28 rpm, covering season of 15 minutes, covering temperature of 30 °C, and covering with "Fe + Zn", "Fe + Zn + Cersan" and dirt individually. In the meantime, the base quinoa-seed germinations of 24.6, 35.4, and 22.5 % by utilizing the covering unit speed of 36 rpm, covering season of 60 minutes, covering temperature of 70 °C, and covering with similar constitutions separately, the maximum machine limit of covered quinoa seeds of 9.0 kg/h was acquired utilizing seeds-group mass of 2.5 kg and covering unit speed of 36 rpm. In the meantime, the base machine limit of covered quinoa seeds of 0.85 kg/h was acquired utilizing seeds-group mass of 0.5 kg and covering unit speed of 20 rpm, the maximum and creation costs at ideal boundaries (lot mass of 2.5 kg, covering unit speed of 28 rpm, covering temperature of 30 °C, covering season of 15 minutes, and covering with "Fe + Zn + Cersan") were 14.15 L. E./h and 4238 L.E./ton.

“…The results obtained at optimum conditions were: germination of coated wheat-grain = 98.1 %, coating-machine performance = 3 -12 kg/h, mass of 1000 coated-grain = 95.7 -98 g, external and internal friction-angles = 18 -20.5 and 21 -23.5 degree, by using fe + Zn coated wheat-seeds: grain emergence = 94.2 %, grain yield = 2186 kg/fed and net profit = 1195 L.E./fed (531 L.E./ton). Yehia et al (2010) found that the maximum fennel, caraway, coriander, nigella and guar seeds germination of 98.1, 96, 98, 100 and 100 % were obtained with coating temperature of 40 C o and coating time of 30 min. Meanwhile, the minimum fennel, caraway, coriander, nigella and guar seeds germination of 63.38, 61.43, 66.3, 67.76 and 70.2 % were obtained with coating temperature of 70 C o and coating time of 70 min.…”

The main results in this study can be summarized in the following points: * The maximum germinations maize seeds were 89.5, 99.6 and 89.7 % for coating-unit speed of 28 rpm, coating time of 15 minute, coating temperature of 30 C o with their different coating treatments coating with "Fe + Zn", "Fe + Zn + Arsan" and clay respectively. Meanwhile, the minimum maize seed germinations of 22.5, 37.8 and 14.7 % were obtain at coating-unit speed of 36 rpm, coating time of 60 minute, coating temperature of 70 C o and coating with the same coating mechanicals respectively. * The maximum machine capacity of maize seeds coated was 9.2 kg/h was obtained using seeds-batch mass of 2.5 kg and coating-unit speed of 36 rpm. Meanwhile, the minimum machine capacity of maize seeds coated was 0.85 kg/h using seeds-batch mass of 0.5 kg and coating-unit speed of 20 rpm. * The operation and production costs at optimum parameters batch mass of 2.5 kg, coating-unit speed 28 rpm, coating temperature of 30 0 C, coating time of 15 minutes and coating with "Fe + Zn + Arsan" were 17.02 L. E./h and 1850 L.E./ton. INTRODUCTION aize (Zea mays, L.) one of the important crops worldwide after rice and wheat because of its high grain and forage yield. El- Habbal et al. (1995) proved that coating the maize corn seeds with fertilizer containing Fe, Mn and Zn (2:1:2 by weight) at the rate of 6.5 g/kg seeds gave significant increments in number of spikes/plant,
