Abstract

Field corn is an important raw material for animal feeds, making it as an extremely high demand in the animal feed processing industry. Nevertheless, in the manufacturing process of field corn, the problems of seed deterioration and the detection of fungi and diseases remain pervasive. The aforementioned problems can be solved through seed conditioning technology to encourage seed enhancement. The enhancement can be done by means of seed priming with a solution of KNO3 and seed coating using different amounts of fungicide. An experiment was conducted at the Seed Technology Laboratory, Faculty of Agricultural Production, Maejo University. The results of the experiment are as follows. Coated seeds with 2, 4 and 6 g.ai. of Metalaxyl had the highest radicle emergence and germination in the laboratory condition. At the same time, the growth of the seedlings when compared to those of non-treated seeds was in the highest level when tested in an experimental greenhouse condition. Meanwhile, coated seeds with 4 g.ai. of Captan had better radicle emergence, seed germination, shoot and root length under laboratory condition. Additionally, the seeds had a higher rate of coleoptile emergence and higher speed of coleoptile emergence compared to those of non-treated seeds in the laboratory condition. Finally, when tested under laboratory conditions, coated seeds with 4 g.ai of Mancozeb had the highest germination rate and root length compared to non-treated seeds. To conclude, seed priming with KNO3 solution and coating with 4 g.ai of Captan had the highest radicle emergence, shoot length, and root length under laboratory condition, and had the highest germination rate, speed of radicle emergence, coleoptile emergence, speed of coleoptile emergence under greenhouse condition compared to those of the non-treated field corn seeds.
