GROWTH RESPONSE OF PALM OIL SEEDLINGS AFTER GIVING SHALLOT EXTRACT AND DIFFERENT SOAKING TIME
Journal Title: ASIAN JOURNAL OF NATURAL & APPLIED SCIENCES - Year 2018, Vol 7, Issue 4
Abstract
The study was aimed to recognize the growth response of palm oil seedlings (Elaeis guineensis Jacq.) in the pre-nursery after giving shallot extracts (Allium cepa L.) and different soaking time. This study used an experimental method by a randomized block design with the factorial pattern. The first factor was the concentration of shallots extract which consisted of 4 levels: 0% (B0), 25% (B1), 50% (B2), 100% (B3). The second factor was the soaking time which consisted of 4 levels, namely 0 hours (P0), 5 hours (P1), 10 hours (P2), 20 hours (P3). The total of all treatments were 16 with 2 repetitions. The data were analyzed by using analysis of variance (ANOVA), followed by Duncan’s Multiple Range Test (DMRT) at a significant of 5%. The results showed that administration of shallots extract and soaking time had no significant effect on the growth (stem diameter, leaf length, root length, wet weight, dry weight) of oil palm seedlings in pre-nursery at the age of 4 until 12 weeks after planting, except giving of soaking time toward the stem diameter growth at the age of 7 weeks after planting. The application of shallots extract and soaking time was able to increase the growth of oil palm seedlings in pre-nursery starting from the 4th until 12th weeks, in spite of having no significant effect. The best treatment of shallots extracts and soaking time resulted in a different growth response of palm oil seedlings in pre-nursery
