Abstract
Soybean seeds have a shelf life of 6 months with storage at room temperature with a water content of 8-12%. The high content of protein and fat cause soybean seeds to experience rapid decline, especially if the storages environmental conditions are not favorable, allowing the process of deteriorating the seeds to be faster. The research was conducted at the Orchids Farm Green House at Dau, Malang and Agronomys Laboratory at Univesity of Muhammadiyah Malang by using completely random Design Completely Random Factorial Design at Laboratory and Randomized Compete Block Factorial Design at Field with two factors that has 3 repetations. First factor is using some invigoration techniques (P), such as; (P1) control, (P2) hydropriming aquadest, (P3) matriconditioning the charcoal of rice husk ash, (P4) matriconditioning+Trichoderma harzianum, (P5) osmoconditioning 0,01 m mol GA3 (P6) osmoconditioning 0,01 mMol GA3+0,1 mMol NAA. Second factor is priming duration (L); (L1) 6 hours , (L2) 12 hours, (L3) 24 hours. The data of observation result was analyzed using varience analysis and followed by the Duncan Multiple Range Test (DMRT) at significance levet of 5%. The results showed that the interaction of treatments between invigoration techniques and immersion time significantly affected the seed vigor index, plant growth speed, root length, number of leaves both field test and laboratory test, number of flowers per plant, flowering age, number of pods per plant and seed weight per plant, especially in the treatment interactions (matriconditioning + Trichoderma harzianum) both either L1, L2, and L3 treatments provide a real and effective influence in increasing seed viability and vigor and plant growth. The invigoration technique given to the seeds had a very significant effect on almost all research variables, especially the matriconditioning + Trichoderma harzianum technique. The duration of immersion with a period of 12 hours is a treatment that provides effective results.
