Jatropha curcas seeds have 30-40% oil content. The purpose of the study was to improve the seed quality and to enhance seedling growth of Jatropha curcas after storage using plant growth regulator. This study used factorial design based on Completely Randomized Design with two factors and 3 replications. The first factor was seed storage which consist of 2 levels : A1 = seed storage in 2015, A2 = seed storage in 2016. The second factor was plant growth regulator level which consists of 6 levels : B1=GA+NAA 0 ppm, B2= GA+NAA 20 ppm, B3= GA+ NAA 40 ppm, B4= GA+NAA 60 ppm, B5 = GA+NAA 80 PPM, B6 = GA+NAA 100 ppm. Parameters measured were seed germination, vigor index, growth rate, plant height and the number of leaves. The data were analyzed statistically by analysis of variance and followed by Tukey test and Polynomial Orthogonal. The result showed that seed germination, vigor index and growth rate were significantly affected by storage treatment and invigoration using plant growth regulator treatment. Invigoration using auxin and gibberellic acid 40 ppm has the highest result of seed germination, vigor index and growth rate. There was no influence of seed storage and invigoration with plant growth regulator treatment on plant height and number of leaves.

This research used monofactor experiment with Completely Randomized Design consist of 7 treatments and 3 replications. The treatments were T0 (control), T1 (GA3 100 ppm and cow manure 6,250 kg / ha), T2 (GA3 200 ppm and cow manure 12,500 kg / ha), T3 (GA3 300 ppm and cow manure 18,750 kg / ha), T4 (GA3 100 ppm and goat manure 3,750 kg / ha), T5 (GA3 200 ppm and goat manure 7,500 kg / ha), T6 (GA3 300 ppm and goat manure 11.250 kg / ha). Observed parameters were plant height, leaf number, leaf area, wet weight and dry weight. The data were processed by analysis of variance and further test with Duncan Multiple Range Test and Contrast Test. The best plant height growth was in the treatment of 18,750 kg / ha of cow manure and 300 ppm gibberellin resulted plant height of 21.11 cm. The highest number of leaves in the treatment of 11,250 kg / ha of goat manure and 300 ppm gibberellin resulted 21.44 leaves. Leaf area (528.79 cm2), fresh weight (68,50 g), and best dry weight (26.97 g) were achieved at 7,500 kg / ha goat manure treatment and 200 ppm giberelin. It was concluded that the application of manure and gibberellin increased plant growth (plant height, leaf number, leaf area), and crop production (fresh weight and dry weight) of red spinach. The combination of goat manure and giberelin was better than cow manure on all parameters. Goat manure of 7,500 kg / ha and 200 ppm gibberellin increased growth and production of red spinach on leaf area parameters, fresh weight, and dry weight.
