The purpose of this study was to look at the effect of organic plus and urea biofertilizers on the growth and yield of (Cucumis sativus L.) interactively or primarily. The experimental design used was factorial Completely Randomized Design (RAL) consisting of 2 factors. The first factor is the provision of Bio-Organic Plus (P) fertilizer which consists of 4 levels, namely: 0, 2,5, 5, 7.5 cc / l water and the second factor is the administration of Urea (U) fertilizer which consists of 4 levels, namely: 0, 1,87, 3,75 and 5,62 g / plant. The parameters observed were an age of flowering, age of harvest, number of fruit crops, fruit weight and fruit weight. The results showed that the interaction of bio-organic plus and urea fertilizers significantly affected the number of fruits per plant, fruit weight per fruit and fruit weight per Suri cucumber plant. The best treatment is a combination of bio-organic fertilizer plus 7,5 cc / l water and urea fertilizer 3,75 g / plant (P3U2). In particular, the provision of bio-organic fertilizer plus significantly affected flowering age, harvest age, number of fruit crops, fruit weight and fruit weight. The best treatment is the administration of bio-organic fertilizer plus 7,5 cc / l water (P3). In particular, the administration of urea significantly affected flowering age, harvest age, number of fruit crops, fruit weight and fruit weight. The best treatment is giving urea fertilizer 3,75 g / plant (U2).

ABSTRACT The purpose of this study was to determine and compare the Morphological, Physical, Storage, and Chemical Characteristics of 4 types of Local Rambutan (Nephelium Sp.). Fruit characteristic test is carried out on Morphology, Physical Properties, Storing Power, and Chemical Content of Rambutan fruit which refers to Descriptor of Rambutan (IPGRI, 2003). This study uses one-way Anova Analysis which is then tested further by BNJ at a 5% level for the Chemical Content Test of fruit. Followed by Klastering Test using MVSP 32 Program with Spearman Coefficient analysis. Morphological observations of fruit quantitatively and qualitatively that is Pulasan has the character of weight, length, diameter, skin weight, aryl weight, and weight of fruit seeds is greater than other types. Lulu has a uniform fruit skin color that is dark red, Sipadeh (N2) also has a uniform color that is yellow / cream. Sipadeh (N1) and Pulasan have a sweeter taste and easier idleness (chipped). This is different from Lulu and Sipadeh (N2), where both types have a sour taste and are difficult to crack (peel) from the seeds. In the chemical test, Sipadeh (N2) and Lulu have a high content of Vitamin C and total titrated acid. Whereas Pulasan and Sipadeh (N1) which have high Dissolved Solid Total Value. The results of the morphological cluster analysis of the fruit produced a dendrogram with a phenolic similarity of -50% to 100%. The results of the cluster chemical analysis result in a dendrogram with Kf -80% to 70%. Keyword: Characteristics, Local Rambutan (Nephelium Sp.)

ABSTRACT The purpose of this study was to determine the interactions and main effects of planting media and NPK 16:16:16 fertilizer on growth and production in vegetable ferns (Diplazium esculentum S.). The design used is a Factorial Complete Random Design. The first factor is the planting media of peat soil and mineral soil consists of 3 levels of treatment, namely: peat soil, mineral soil and a combination of 1: 1 peat and mineral soil while the second factor is NPK 16:16:16 fertilizer with 4 levels of treatment, namely: 0, 0.3, 0.6 and 0.9 g / polybag so that 12 treatment combinations were obtained, with 3 replications, then a total of 36 experimental units were obtained. Each unit consists of 4 plants with 2 plants used as samples. Observation parameters consisted of the age of emergence of shoots, plant height, number of young leaves, economical wet weight and dry weight. The results showed that the interaction of planting media and NPK 16:16:16 fertilizers gave a real influence on the number of young leaves with the best treatment was the planting media of a combination of peat and mineral soil 1: 1 and 0.6 g NPK fertilizer 16:16:16 (M3N2 ). The main effect of the planting medium was evident on the parameters of plant height, number of young leaves, economic wet weight, and dry weight. The best treatment is found in a combination of peat and mineral media 1: 1 (M3). The main effect of NPK 16:16:16 was significantly affected by the number of young leaves, economic wet weight and dry weight with the best treatment of 0.3 g (N1).

Dayak onion has many benefits, namely anti-inflammatory, stopping the bleeding, anti-breast cancer, heart disease prevention, immunostimulant, anti-tumor, high blood pressure-lowering drugs (hypertension), and diabetes. Dayak onion bulbs contain flavonoids, saponins, polyphenols, alkaloids, glycosides, steroids, phenolics, tannins, triterpenoids, and quinones. DI Grow liquid organic fertilizer is the latest generation of organic fertilizer in agriculture. This fertilizer contains nutrients at a balanced level and also plant growth regulators such as auxin, gibberellin, and cytokinin. This research aims to find out the interaction and the main effect of planting distance and DI Grow liquid organic fertilizer to the growth and the yield of Dayak onion. The research was carried out in the Experimental farm of the Faculty of Agriculture, Islamic University of Riau, Pekanbaru. This research was carried out during 7 months, starting from April to November 2018. The experimental design is a Completely Randomized Factorial Design. The observed parameters are the relative growth rate, net assimilation rate, the number of clump tubers, clump wet weight, and clump dry weight. The results showed that the interaction between planting distance and DI Grow fertilizer did not significantly affect on all the observed parameters. The main effect of planting distance and DI Grow fertilizer was found on all parameters with the best treatment at a planting distance of 25x30 (J4) and DI Grow fertilizer dose of 9 ml/L of water (D3).

The development of kepok bananas in Indonesia generally uses banana sapling, but this technique has weaknesses such as low uniformity and takes a long time. So, it is necessary to get the latest techniques such as the technique of splitting humps which is easier and cheaper. In addition, its development requires the balanced fertilization techniques using inorganic and organic fertilizers. This study aims to determine the effect of interaction and the main effect of NPK Grower and banana humps liquid organic fertilizer (LOF) on the growth of kepok banana seedlings (Musa paradisiaca) by using the splitting humps. This research was carried out at the Experimental farm of the Faculty of Agriculture, Riau Islamic University, Pekanbaru City. The study was conducted from March to May 2021. The research design used a completely randomized design (CRD) with two factors. The first factor was the concentration of NPK Grower (G), which consisted of 4 levels, which were 0 g/plant, 15 g/plant, 30 g/plant, and 45 g/plant. The second factor was LOF banana humps (P), consisting of 4 levels, namely 0%, 15%, 30%, and 45% which consisted of 3 replications. The parameters observed were the percentage of growth, budding time, plant height, number of leaves, stem girth, longest leaf length, and widest leaf width. The data were statistically analyzed and continued with the honest significant difference test (HSD) at the 5% level. The results showed that there was a significant interaction between NPK Grower and banana humps LOF on the parameters of plant height, number of leaves, stem girth, longest leaf length, and widest leaf width. The best treatment was found in NPK Grower with a dose of 45 g/plant combined with a concentration of LOF banana humps of 300 ml/lair.
