Abstract

Effectiveness composting Trichoderma sp. Against the Plant Growth Chilli (Capsicum annum L.)The objective of this study was to determine the effectiveness of compost Trichoderma sp. at the time of the nursery and moving the field on red pepper plants. This experiment was conducted February to April 2015, using a factorial randomized complete block design with three replications. The first factor seedling media (MT = Media soil + compost Trichoderma sp. With a volume ratio of 1: 1, MK = Media soil + compost Simantri the ratio of 1: 1, M = Media ground). The second factor in the media field (mt = Media soil + compost Trichoderma sp. With a volume ratio of 1: 1, mk = Media soil + compost Simantri the ratio of 1: 1, m = Media ground). The results showed that: there is interaction between media seedlings with the media on the field, the variables plant height and yield fruit of pepper plants in the field. The best treatment is shown by the media's treatment (MTmk) at high variable pepper is 61.67 cm and the media (MTmt) high were obtained are 60.78 cm. In the fruit of the pepper plant variables highest results in treatment (MTmt) with the amount of 916.67 g but not significantly different from the treatment (MKmt) with the results of 813.33 g.

Abstract

The Effect of Composition Planting Medium and Inorganic Compound Fertilizer application on The Growth of Early Oil Palm Seeds(Elaeis guineensis Jacq.) This study aims to: understand the interaction effect of composition planting medium and inorganic compound fertilizer application on the growth of early oil palm seeds (Elaeis guineensis Jacq). Research on the effect of composition planting medium and inorganic compound fertilizer using factorial randomized block design with two factors, namely: (planting medium, compost: soil: sand) which consists of four levels, namely: (0 compost: 1 soil: 1 sand), (1 compost: 1 soil: 1 sand), (2 compost: 1 soil: 1 sand), (3 compost: 1 soil: 1 sand), while the inorganic compound fertilizer application consists of three levels, namely: 0 g / polybag; 2.5 g / polybag; 5 g / polybag. Observations were made on plant height, stem diameter, leaf area, number of leaf chlorophyl, oven dry weight of shoots, roots oven dry weight, total dry weight of seedlings, shoot ratio, plant growth rate, and net assimilation rate. Data were analyzed by analysis of variance and if the real effect will be tested further with LSD 5%.The results of this study indicate that the interaction of composition planting media and inorganic compound fertilizers are not significant to the growth of early oil palm seeds (Elaeis guineensis Jacq). Single factor of planting medium and inorganic compound fertilizer is not significant to the growth of early oil palm seedlings (Elaies guineensis Jacq.). The highest value seen in the growing compost media composition: soil: sand (2: 1: 1), inorganic compound fertilizer highest value contained in a dose of 2.5 g / polybag on parameters of leaf area, leaf chlorophyll, dry root weight of the oven, and total weight of oven dried beans.

Abstract

The Attempt to Improve the Quality of Balinese Grapevine Fruits (Vitis vinifera L. Var Alphonso Lavallee) With GA Application from Bamboo Shoot Extract at The Blooming Phase Balinese table grape is one of the superior fruit in Bali. Balinese table grape less salable than imported grapes because of the lack of the sweetness, small fruit size and the presence of the seeds are the weaknesses of Balinese table grapes quality. This study aims to determine the effectiveness of the bamboo shoots extract at the blooming phase to improve fruit quality. The experimental design used was a Randomized Block Design with 5 treatments and 5 replications. The treatments are different concentration of bamboo shoot extract including without bamboo shoot extract (control), 25%, 50%, 75% and 100% of bamboo shoot extract. The observed variables were fruitset length, number of fruit per fruitset, fruit weight per fruitset, weight per fruit, number of seeds per fruit, total soluble solids and organoleptic test. The result showed that 100% bamboo shoot extract concentration was able to improve the quality of Balinese grapevines with fruitset length of 20.93 cm increased by 157.3% compared to control, the number of seeds 1.36 decreased by 54% compared to control, and total soluble solids 8.79oBrix increased by 122.8% compared with controls.

Abstract

The Influence of Type of Rhizobacteria on Growth and Yield of Soybean Crops (Glycine Max (L). Merril) This study aims to determine the type of rhizobacteria that have better ability in increasing the growth and yield of soybean crops. The research was conducted in August 2016 until December 2016, located in Angantaka Village, Abiansemal District, Badung Regency. The design used was Randomized Block Design consisting of 5 treatments, using 5 replications. This study observed plant height, number of leaves, number of branches, leaf chlorophyll content, fresh weight of plant parts above soil, fresh weight of underground plant parts, weight of oven dried above ground plant parts, weight of oven dried underground plant part, root nodules per plant, number of pods per plant, number of contained pods per plant, total weight of seed per plant, weight of 1000 seeds, soybean yield per hectare.The results showed that all four rhizobacteria RB35 (undis 1), RB36 (undis 3), RB3 (kara benguk), and RB9 (lamtoro) were able to increase the growth and yield of soybean crops. However, most effective of the four rhizobacteria are RB35 (Undis 1) and RB36 (undis 3). The use of rhizobacteria RB35 (5.59 tons ha-1) and RB36 (5.47 tons ha-1) gave the highest yield of soybean and was not significantly different between the two. Rhizobacteria RB35 (Undis 1) yielded 126.32% and rhizobacteria RB36 (Undis 3) 121.46% compared with plants without rhizobacteria or control (2.47 tons ha-1).

Abstract

The Influence of Several Types of Fertilizers and Seeds Against Growth and Rice Yields (Oryza sativa L.). The research was carried out in a plastic house located in Banjar Kumuda Loka, Telaga Village, Busungbiu District, Buleleng Regency. The study was conducted from January 2017 to April 2017. The purpose of this study was to determine the type or combination of fertilizers and the age of the best seeds used that can provide maximum growth and yield of rice crops. This study was prepared using Factorial Randomized Block Design (RBD) with two factors. The first factor is the provision of fertilizer consisting of four level namely; fertilizing the farmer's way, organic fertilizer (solid + liquid), chemical fertilizer and organic fertilizer + chemical. The 2nd factor is the age difference of seeds consisting of three level namely; seed germinate, seven days after germinate and fourteen days after germinate. Each treatment was repeated three times. The results showed that the interaction between fertilization and seeding age had a significant effect on panicle length and the real impact on the harvest index. In single fertilizer were very significant to plant height, number of leaves, number of maximum and productive tillers, leaf area, number of panicles per hill, dry yield of harvest and dry oven per hill, Heavy wet and dry straw oven. While the treatment of seedlings had significant effect on plant height, number of leaves, number of maximum tillers, number of grains per panicle, panicle length and weight of grain per panicle. The highest yield (6.58 tons/ha) was obtained from a combination of organic and chemical fertilization with seeding age of 7 days after germinate.
