EFFECTIVENESS TEST OF PLANT GROWTH REGULATOR (PGR) ON GROWTH AND PRODUCTION OF RED ONION (Allium ascalonicum L.).

Abstract

Efforts to increase onion production are faced with higher prices of chemical fertilizers and residues in the soil. The growth regulator is a non-nutrient organic compound that in low concentration can encourage, inhibit or qualitatively alter the growth and development of the plant. PGR applications in plants may affect the orientation of asymilat transport, senator delays and cell enlargement. The effect of PGR application on a plant will be obvious if the condition of the plant is healthy, nutrient needs are met and good maintenance. The aim of this research is to get PGR from sweet corn, pulut corn, yellow corn, and white corn that can increase the growth and production of one of red onion plant varieties. The results showed that sweet corn PGR showed significant result both growth component and production component of onion plant. And red onion that has high production is red onion of Bima Brebes varieties.
