The cultivation of plants melon in Riau based on condition growing is in line, but there were several obstacles such as the land in Riau levels of fertility land which is low.This research aims to determine the combination of doses of an empty oil palm bunches of compost and fertilizer n, p, k the best against growth and melon crop production (Cucumis melo L.) in the trial gardenFaculty of Agriculture, University of Riau. This research was conducted on February 2015 until June 2015. The research has been carried out experimentally in the form of Randomized Completely Design Factorial 2 x 4. The first factor is the dose compost of oil palm empty fruit bunches consist of two levels and the second factor is the dose of N (ZA) fertilizer, P (TSP) fertilizer and K (KCL) fertilizer consist of four levels. Data analyzed by ANOVA and further tested using by Duncan`s New Multiple Range Test (DNMRT) at the level of 5%.parameter made were higher plants, diameter of stem, appears the male flowers and female flowers, diameter of fruits, weight of fruits per sampel and weightof fruits per plot. The results showed the treatment compost of oil palm empty fruit bunches and N, P, K fertilizer significantly affect on the plants height, diameter of stem, appears the male flowers and female flowers but not significant on the diameter of fruits, weight of fruits per sampel and weightof fruits per plot. The application compost of oil palm empty fruit bunches with dose of 20 tons/ha and ZA fertilizer 120 kg/ ha, TSP fertilizer 80 kg/ha, KCl 200 kg/ ha is the best dose in order to enchance growth and production of melon

Pengaruh Tegangan Air Terhadap Efisiensi Pemupukan N, P, Dan K Pada Tanaman Padi Gogo Lokal Varietas Kalpatali (Oryza Sativa L.) Di Tanah Ultisol

This research is held at the greenhouse of Faculty of Agriculture, University of Riau, Pekanbaru starts in March to August 2016. The trial uses the factorial of Complete Random Program (RAL). The first factor of the water tension comprises of three levels, they are : (pF 1 - 1,97), (pF 2,29 - 2,54) and (pF 2,70 - 3) and the second factor of the fertilization dosage of N, P, and K which comprises of four levels without fertilization of N, P, and K, given ½ x recommended dosage, given recommended dosage, and given 1½ x recommended dosage. The process is repeated three times. The data of observation result could be statistically analysed with ANOVA and followed by Duncan test at 5% level. The observed parametre are nutrients uptake of N, P and K, the efficiency of absorption of N, P, and K, height of plants, phase of malai's appearances, number of productive tiller, ratio of stem and root, period of harvest, weight of 1000 paddy seeds and product efficiency. The result of this research shows the interaction of water tension and fertilisation dosage of N, P, and K visibly influnce the nutrients of N, P, and K, height of plants, ratio of stem and root, and weight of 1000 paddy seeds. Invisibly influence to the phase of malai's appearances, period of harvest, and number of productive tiller. Combination of water tension pF 1 - 1,97 and fertilization dosage 1 ½ x recommeded dosage are the best combinations

The first factor is a mixture of ultisol sub soil with compost TKKS (C) based on the volume that consists of 3 levels, were : C1 = (1:2), C2 = (1:1), C3 = (2:1), the second factor is the watering volume (A) consisting of 3 levels, were :A1= 2 liter,A2= 1,5 liter, A3= 1 liter. Thus there are 9 combined treatment and 27 units of trial and each experimental unit contained two plants so that overall there are 54 plans. Results of analysis of variance followed by Duncan's New Multiple Range Test (DNMRT) at 5%. The results showed that the interaction of a mixture of ultisol sub soil with compost TKKS the ratio of 1:2 and watering volume of 1.5 liter/day give the best effect on all parameters abserved

Pemberian Pupuk Kascing dan Urin Sapi pada Bibit Kelapa Sawit (Elaeis Guineensis Jacq.) di Main Nursery

The research aimed to determine the effect of interaction giving of vermicompost fertilizer and cow urine to the growth of oil palm seeds (Elaeis guineensis Jacq.) and get a suitable combination for the growth of oil palm seedlings in main nursery. The research was conducted from April to July 2015. The research used to completely randomized design (CRD) factorial consisting of two factors . The first factor is vermicompost fertilizer consists of 4 levels: vermicompost fertilizer dose of 0 g/plant, vermicompost fertilizer dose of 25 g/plant, vermicompost fertilizer dose of 50 g/plant and vermicompost fertilizer dose of 75 g/plant. The second factor is the concentration of cow urine consists of 4 levels: cow urine concentrations of 0%, cow urine concentration of 20%, cow urine concentration of 30%/ and cow urine concentration of 40%. From two factors then obtained 16 combined treatment with 3 replications. Parameters measured were increase of seed high, increase of midrib number, increase of hump circumference, root volume, root crown ratio and dry seeds weight. The data were analyzed using ANOVA followed by Duncan further test at 5% level. The results of the research showed that application vermicompost fertilizer and cow urine on oil palm seed there is interaction between giving of vermicompost fertilizer and cow urine on increase of seed high and increase of hump circumference. Combination treatment of vermicompost fertilizer dose with 125 g/plant and cow urine concentration of 40 % showed the best results of all observed parameters

The second factor is planting distance consists of 3 levels (10 × 20, 15 × 20 and 20 × 20 cm), combination is repeated three times respectively. The efect of each treatment combination known through Duncan multiple test 5% level. Parameters measured were leaf area, root nodule effective, flowering time, the percentage of pods pithy, pithy number of pods per plant and yield per plot. The results showed that the combination of composting palm empty fruit bunch with planting distance effect on the effective root nodules, number of pods pithy planting, production per plot but did not affect the leaf area, flowering time, the percentage of pods pithy. The highest production was found in compost treatment of palm empty fruit bunches of 20 ton / ha and distance of (15 × 20) cm with a production that is 1717.2 g / plot
