Seedling Performance, Growth and Yield of Onion Sown by Direct Seeding in Tropical Riparian Soil

The objective of this study was to obtain a seed-origin onion (Allium cepa L.) that able grow in the tropical riparian soil. Research designed with non-experimental. Two cultivars were studied, namely Sanren and Lokananta. Onion seeds planted directly without transplanting, there three plots (4 m x 1.6 0.3 m) germination testplot (1 m). Soil tillage, spacing/ population, fertilization, plant maintenance pest-diseases control accordance recommendations. result obtained had higher (94.40%) vigor index (60.60) then growth two showed good performance because no transplanting. Almost all variables for seedlings, vegetative organs bulbs significantly different between cultivars. From boxplot test, it found data symmetry (number stems, dry weight leaves, bulb), Lokananta cultivar (vigor index, number bulbs, height leaf weight). There significant correlation (plant roots), roots stems Fresh per clump from (46.71 g) (17.84 g).
