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.

Inoculation Treatment

Nitrogen is an important macronutrient mineral that is needed in the largest amount by the plant and is the main limiting factor for plant development. Rhizobium is a group of bacteria capable of providing nutrients for soybean crops. When symbiotic with legume crops, this group of bacteria is able to infect plant roots and form root nodules. The study aimed to investigate the effect of Rhizobium on nodulation and growth of some soybean germplasm. The results showed no interaction between the inoculation treatment and the genotype. The significant effect of inoculation was shown by the number of nodules, nodule dry weight, root length, and root dry weight. Inoculation did not affect plant height and shoot dry weight. These traits were more influenced by genetic factors. In the condition without inoculation, the root length was higher but the root dry weight was lower. Plant height differed between the genotypes. KPT5 and KPT6 showed the highest plant height than any other genotypes. Both genotypes also had the highest shoot dry weight. The highest shoot dry weight was also achieved by KPT4.
