Increasing the Onion Yield by the Arrangement of Growing Space and Organic Fertilizer

Abstract

Then aims of this research is for getting the right growth space and optimal concentration of D.I Grow fertilizer so that the maximum growth and yield of onion can be obtained. This research has been carried out in Angseri Village, Baturiti District, Tabanan Regency, Bali Province. This experiment used a randomized block design with a factorial pattern consisting of 2 factors, namely the arrangement of growing space and the concentration of Diamond Interest (D.I.) fertilizer which consisted of 4 levels each. The interaction between the growing space and the concentration of D.I.Grow fertilizer had no significant effect (P≥0.05) on all observed variables. The arrangement of growing space has a very real (P <0.01) effect on maximum plant height, maximum leaf number and number of tubers per clump; has significant effect (P <0.05) on the fresh weight and dry weight of tuber oven per clump as well as fresh weight and dry weight of stover oven per clump and no significant effect (P≥0.05) on the harvest index. The treatment of D.I. Grow fertilizer concentration significantly effected (P <0.05) to the maximum plant height and fresh weight and dry weight of stover, and had a very real (P <0.01) effect on the maximum number of leaves and the number of tubers per clump . However, the effect is not real (P> 0.05) on the fresh weight and dry weight of the tuber oven per clump and harvest index. The highest fresh weight and oven dry weight of tuber per clump was obtained in the setting of the growing space of 20 cm x 20 cm, namely 44.17 g and 4.52 g increased by 18.92% and 88.33% compared to the lowest yield in the arrangement of space growing 20 cm x 10 cm is 37.14 g and 2.40 g. The increasing amount of fertillizer concentration of DI Grow caused the increasing of the growth and yield of onion. The highest number of tubers per clump was at 7,5 ml.l of DI Grow fertilizer concentration, which was 8.11 tubers, which increased by 22.87% which was not significantly different at the concentration of DI Grow fertilizer 7,5 ml.l which was 18.02 tubers increasing by 21.52 % compared with a concentration of fertilizer D I Grow 0 ml l-l wich is 6,60 ubers.
