INVIGORASI BENIH JAGUNG MANIS (Zea mays L. saccharata Sturt) PADA BERBAGAI JENIS PRIMING ORGANIK DAN LAMA PERENDAMAN

Priming is one method to increase the viability and vigour of seeds that have experienced a decline. Priming materials consist of inorganic and organic priming studies to determine the effect of organic priming and soaking time on degenerated sweet corn seeds. The study was a completely randomized design with randomised and three replications. The first factor was the priming material type, consisting of four levels: without priming agent, PEG 6000 15%, coconut water 15%, and tomato fruit extract 15%. The second factor is the soaking duration which consists of two of The results showed that coconut water was the best organic priming agent and increased germination power, germination speed, growth uniformity, and corn seed germination dry weight of 6.33%, 4.29%/etmal, 6.17%, and 0.028 grams respectively compared to the seeds before priming, and when compared to the control, coconut water increased germination by 3.3%, germination speed by 2.8%/etmal, growth uniformity by 4.5%, and germination dry weight by 0.022 grams. Soaking the seeds for 24 hours gave better results than 12 hours for all observed parameters and there was no interaction. The type of organic priming material and the soaking time for all parameters were observed. Coconut water can be an alternative to inorganic priming in improving the ability of deteriorated sweet corn seeds.
