dc.description.abstractThis study was conducted from March 21 to May 28, 2008 at Bumbuneg San Gabriel, La Union. It aimed to determine which of the mulching materials produced the best yield of multiplier onion. An area of 100 square meters was used in this study. The area was recently used or cultivated for rice production. The area was laid out using the Randomized Complete Block Design (RCBD) with four treatment replicated four times. The treatments were as follows: T0 - Control (no mulch) T1 - Rice straw T2 - Banana leaves T3 - Polyethylene plastic Results revealed that the mulching materials such as rice straw has a significant effect on the diameter of onion bulbs, however dried banana leaves and polyethylene plastic have a comparable effect on multiplier onion in terms of plant height, size of bulblet, and yield of harvested fresh onion bulb. Result showed that the tallest onion plants at 3 weeks were those mulched with banana leaves (T2) with a mean of 167.20 cm, while the shortest leaves were obtained by those mulched with polyethylene plastics (T3) with a mean of 132.59 cm. Analysis of variance showed no significant effect of mulching materials on the height of onion. The onion plant without mulch (T0) registered the most number of leaves with a mean of 15.25, closely followed with the plant mulched with rice straw (T1) and the plant mulched with banana leaves (T2) with a mean of 14.80 and 14.03, respectively. The least number of leaves was observed in polyethylene plastic (T3) with a mean of 13.46. On the other hand, onion mulched with rice straw (T1) had the longest polar diameter with a mean of 1.35 cm, while the shortest were those onion plant mulched with polyethylene plastics (T3) with a mean of 1.22 cm. Significant result was obtained in the analysis of variance. Based on the result of economic analysis of the study. The highest net return per treatment of onion was obtained in rice straw (T1) with computed ROI of 91.73. The result of correlation between some agronomical parameter with temperature and rainfall show that there is moderate relationship between temperature and plant height in all treatments.
