| Abstract | ||||
| This study was carried out to design simple equipment for seed coating using mixture from organic and inorganic filler. The experiments were conducted at El-Serw agricultural research station – Damietta governorate – Egypt at season 2019. The coating equipment consists of main frame, spinning as coating unit, power source and power transmutation unit. Experiments were run with a small batch processing capability. Locally available mixture of soft compost and calcium peroxide were tried and tested for possible application as coating material at coating unit tilt angles (20, 40 and 60°); rotating speeds (40, 60, 80 and 100 rpm) and coating times (3, 6, 9 and 12 minutes). The evaluation included two types of seeds (radish and sugar beet). Results indicated that germination, duplicity, productivity, weight of 1000 coated seed, static coefficient of friction and repose angle were (82 and 85 %); (6.1 and 4.8 %); (6.9 and 9.5 kg/h.); (36 and 43 gram); (0.50, and 0.42); and (31 and 23°) at tilt angle of 40°, rotating speed of 80 rpm and 3 min. for radish and sugar beet, respectively. At field experiment with planting sugar beet it was needed about 2.0 – 2.5 kg/fed substitutional about 4 – 4.5 kg/fed in traditional method. That save about 50% amount of seeds. | ||||
