Efficiency of nutrients coating on Khao Dawk Mali 105 Rice Seed Quality

Abstract

The objective of this experiment was to enhance Khao Dawk Mali 105 seeds quality by seed coating with plant nutrients. The data of seed germination, speed of germination and seedling growths were evaluated in this experiment. The experiment was conducted at the Faculty of Agriculture and Agricultural Industry, Surindra Rajabhat University. This experimental design was a Completely Randomized Design: CRD with 4 replications. There were eight treatments including non – coated seed (control), and seed coated with polymer and plant nutrients at a rate of 0, 0.25, 0.50, 0.75, 1.00, 1.25 and 1.50 ml. The coated seeds were tested for seed quality. The results indicated that the seeds coated with 0.50 ml of plant nutrients had higher germination which was 100% under laboratory conditions and seed vigor was between 19.80 and 19.92 plants/day higher than the control. For the growth of seedings at the age of 14 days after sowing seed coated with polymer and plant nutrients at the rate of 0.50 ml tended to give root length and shoot length longer than other treatments. But, when the nutrients were increased to 1.50 ml, the seed germination and the seed vigor were lower than the control.
