An intensive research about the application of Oil palm frond (OPF) organic fertilizer on paddy rice and soybean had been done for consecutive three years. The crops showed better growth and yield by years by OPF organic fertilizer compared to farmyard manure and chemical fertilizer. This finding was due to the adequate nutrient contents in OPF organic fertilizer which consist of more than 4% of N, P and K as required by national organic standard (SNI). However, the C/N ratio was rather high which more than 25%. This research aimed to evaluate new formulations of OPF organic fertilizer with the intention of finding ideal C/N ratio as required by SNI. In order to meet this objective, the study was conducted by mixing OPF chopped with various high N content organic materials. The best formulation was mixing of OPF chopped with oil palm leaves, farmyard manure and fish waste liquid fertilizer. The N content in this new formulation was 2.10% which was higher than previous OPF formulation 1.52%. Thus the C/N ratio became much lower in new formulation compared to previous one, 13.83% and 35.96% consecutively.

Oil palm fronds have huge potential to be developed as a source of organic fertiliser by chopping hard frond to become soft smooth pieces and ready to be proceed in bokashi fertilising system. This research aimed to evaluate the application of oil palm frond organic fertiliser on soybean growth and yield compared to cow manure and chemical fertilisers. Three levels of Nitrogen were applied 60, 90 and 120 kg of N/ha. This study had been done in Padang Rambun village, Seluma District, Bengkulu Province under wet land rice field condition and using rice-soybean rotation. Split plot design and least significant design (LSD) 5% were applied to analyse the data. The results showed that kinds and dosage levels gave very significant effect to all parameters but there was no significant effect between them. LSD analysis proved that oil palm frond organic fertiliser was better than manure bokashi in term of plant height and number of pods but had no significant effect on weight of seeds per plot. Furthermore, increasing of nitrogen level improved growth and yield of soybean meaning that the dosage given did not meet the optimum level for soybean growth and yield.

The administration of organic fertilizer to provide nutrients for plants is insufficient. It is because organic fertilizers contain low nutrients. Thus, plants need more nutrients that are obtainable from the administration of inorganic fertilizers. This research aimed to find: the effects of the best types of organic fertilizers on the growth and yields of cucumbers; the effects of the dose of NPK compound fertilizers on the growth and yields of cucumber; and the effects of interaction between the various types of organic fertilizer and the dose of NOK compound fertilizers on the growth and yields of cucumber. This research used Factorial Randomized Block Design with three replications. The first factor was the Various Types of Organic Fertilizers consisting of Without Organic Fertilizers, Goat Manure, and Petrogranik Organic Fertilizers. The second factor was the dose of NPK compound fertilizers of 200, 250, and 300 kg/ha. Analysis of variance was then performed and followed by Duncan Multiple Range Test (DMRT). Research results indicated that the treatment with various types of organic fertilizers provided significant effects on all observed variables; in the treatment with the Dose of NPK compound fertilizers provided significant effects on the plant and fruit weights and did not provide significant effects on other variables; interaction of various types of organic fertilizers and the dose of NPK compound fertilizers did not provide significant effects on all observed variables; Various types of organic fertilizer, such as goat manure provided the best growth and yields; the Dose of NPK compound fertilizers of 250kg/ha provided the best growth and yields of cucumbers.
