Application of Drip Irrigation on Various Planting Media and Cow Urine in the Main Media of Preliminary Oil Palm Nursery

Abstract

The objective of this study was to determine the effect of drip irrigation and biological organic fertilizer treatment on oil palm growth. This study used a randomized complete block design with 3 replications. This research consisted of three experiments, namely drip irrigation, planting media composition, and cow urine dose on the growth of oil palm seedlings. There are three levels of drip irrigation, namely 30 minutes, 60 minutes and 90 minutes. Experiments on the type of planting media composition consisted of two types, namely M1 (ultisol soil + husk charcoal + fern fertilizer) and M2 (ultisol soil + empty bunches + goat manure). The cow urine experiment consisted of three levels, namely 100 ml, 150 ml, 300 ml. The results showed that giving water for 30 minutes gave the best results on stem circumference, plant height increase, plant dry weight increase, plant wet weight increase in oil palm seedlings. M1 media (ultisol soil + husk charcoal + fern fertilizer) had a significant effect on the increase in plant height, wet weight and dry weight of oil palm seedlings. Treatment of 150 ml cow urine liquid fertilizer is sufficient for the needs of oil palm seedlings with a response that is not different from 200 ml of cow urine.
