Abstract

From the experiment of using liquid urea fertilizer at different rates to increase the growth and yield of onion in Hua Sa Village, Ba Jiang Charoen Suk District, Champasak province, it was found that: the use of liquid urea fertilizer at different rates of 10 20 30 cc/20 liters of water was added before planting.

            The experimental planning is RCBD (Randomized Completely Block Design), consisting of 4 experimental cells (4 Treatments), 3 replications (3 Replications), 12 experimental units (12 Unit Experiments), through the experiment of using liquid urea fertilizer in different amounts for the growth and yield of onion to find the rate of urea fertilizer that is suitable for the growth and yield of onion, through data collection shows that: application of liquid urea fertilizer to onion division at different rates. Onion division increased in height each week, with a higher number of leaves and yield, although the statistical analysis did not show any difference. It is the 4th experiment that uses urea fertilizer at the rate of 30 cc/20 liters of water. The weight of the average yield is the best which is equal to 5.5 kg/2m2 or equal to 27.5 T/ha, followed by the 2nd, 3rd, and 1st experiments with an average yield equal to 26, 24, and 21.5 T/ha respectively.

            Therefore, it can be concluded that: applying urea fertilizer at a rate of 30 cc/20 liters of water has a higher average yield and helps raise the organic matter in the soil to a high level, and makes the soil have more nutrients for plants.
