The Effect of Plant Growth Regulator to Yield of Job's Tear (Coix lacryma-jobi L.) in Sumedang Indonesia

Tati Nurmala, Asep Hidayat, Ruminta

Abstract: Jobs tear is a cereal plant that can be used as food and feed with high contains of protein, fat, and vitamins. Productivity of jobs tears need to be developed and improved through the adjustment of the genoypes and cultivation techniques. The objective of this research were to select the genotypes of jobs tear with high yield, and to study the interaction effect of genotypes with the plant growth regulator application to yield. The experiment was conducted from June 2014-February 2015 in Rancakalong Sumedang Indonesia. The experimental design used in this research was factorial randomized block design with four replications. The first factor was six genotypes of jobs tear and the second factor was plant growth regulator application (gibberelins and paclobutrazol). The differences among treatment means were compared using Least Significant Difference (LSD) test at 5 % probability level. The result showed that was the interaction effect between application of gibberellins and paclobutrazol with six genotypes of jobs tear on seeds weight per hill, seeds weight plot, seeds weight per ha, and harvest index. The best genotype of jobs tear was G38 with the highest yield reached 4.09 tons ha-1 which was treated with giberellins and paclobutrazol 12 ml L-1.
