Abstract

The decrease in the quality of bananas can be caused by the attack of the pathogen Colletotrichum musae which causes anthracnose disease. The use of the antagonist fungus Trichoderma harzianum can be relied upon to control this disease. This study aimed to obtain a more effective level of T. harzianum spore density to suppress the development of anthracnose disease in Ambon bananas. The treatment tested was T. harzianum with five levels of spore density, namely 105, 106, 107,108, and 109 spore/mL, designed using a completely randomized design with five replications. The variables observed were the incubation period and the intensity of the disease. The results showed that the spore density of 109 was effective in suppressing the development of anthracnose disease by inhibiting the incubation period to 3.85 days and suppressing the intensity of the disease to 41.4%.Keywords: Banana, Trichoderma harzianum, Anthracnose, Colletotrichum musae

Abstract

Bio boost is a biological fertilizer containing superior soil microorganisms, useful for increasing soil fertility as a result of soil biochemical processes. Bio boost biofertilizer contains Azotobacter sp., Azospirillum sp., Bacillus sp., Pseudomonas sp., and Cytophaga sp. One of the applications of organic cultivation is the use of biological fertilizers in the cultivation of melons. Melon is a horticultural commodity that has a fairly high economic value and is profitable to be cultivated as a source of farmers' income. This research was conducted in Jamaimo Village, Mariat District, Sorong Regency from July to November 2020. This study used a single factor with a randomized block design consisting of 4 levels of treatment. Each treatment was repeated 4 times so that 16 experimental units were obtained. The concentration of Bio boost treatment is as follows: P1 = Treatment with a concentration of 500 ml bio boost + 1000 ml water; P2 = Treatment with a concentration of 700 ml bio boost + 800 ml water; P3 = Treatment with a concentration of 900 ml bio boost + 600 ml water; P4 = Treatment with a concentration of 1100 ml bio boost + 400 ml water. The results of the study found that the application of bioboost with various concentrations affected the length of the vine, the number of leaves, the weight of the fruit and the fruit diameter of the melon plant. Treatment with a concentration of 1100 ml bioboost + 400 ml water (P4) can increase the length of the tendrils up to 108.34 cm, the number of leaves 42.75, fruit weight 1.61 kg, and melon diameter 17.56 cm.Keywords: Organic_fertiliser; Bioboost; Melon

Abstract

The addition of organic matter is done to overcome the problems that occur in acid soils such as inceptisols. The aim of the research was to develop organic fertilizer enriched in granular form from campus litter compost to improve soil physical properties and maize yield in Inceptisols. The treatments consisted of: no fertilizer (KGSK1), 8 t ha-1 granule compost (KGSK2), inorganic fertilizer (Urea, SP-36, and KCl) recommended dose (KGSK3), inorganic fertilizer + 8 t ha- granule compost (KGSK4 ), x dose of inorganic fertilizer + compost granule (8 t ha-1) (KGSK5), 2 times dose of inorganic fertilizer + compost granule 8 t ha-1 (KGSK6), x dose of inorganic fertilizer + compost granule 12 t ha- 1 (KGSK7) and 2 times the dose of inorganic fertilizer + compost 4 t ha (KGSK8). The study was designed using a randomized block design with three replications. The results of the study found that the provision of enriched campus litter granules, either applied singly or in combination with inorganic fertilizers, had a significant effect on improving soil physical properties, namely soil volume weight, soil specific gravity, soil porosity, fast drainage pores, slow drainage pores, water pores. available, and unavailable pore water were 0.90 g cm-3, 2.30 g cm-3, 7.77%, 23.54%, 8.83%, 11.62%, and 249.17%, and the yield of dry shelled corn was 7.85 tons ha- 1.Keywords: Granular compost, Corn, Inceptisol, inorganic fertilizer

Abstract

 This study aims to determine the species composition, frequency, density, dominance, important value index (INP) and the distribution of tree species. The method used in this research is the Line Transect Plot Method. The total area of the sample plots is 1 ha (10.000 m2) with a total of 25 sample plots, which are placed purposively at the study site. Observational data were analyzed according to the parameters and described qualitatively and quantitatively and presented in the form of tabulations and pictures. The composition of vegetation types in the Sorong Nature Tourism Park forest contains 50 plant species, namely 30 known families and 3 plant species not yet traded, scientific and family names. The number of tree levels is 36 species with the largest density value (K) for resak (Vatica papuana) and guava (Syzygium, sp ) which is 29.81/ha with a Relative Density (KR) of 15.897% with the smallest density value (K). 0.962/ha, and the value of relative density (KR) was 0.5128%, respectively. The largest frequency (F) value is found in guava with a value of 0.731, relative frequency (FR) of 13.19%, and the lowest value of frequency (F) is 0.038 %, the smallest relative frequency (FR) is 0.694%. With the largest dominance value (C) in resak plants of 2,561 and relative dominance of 15.95%, while the lowest dominance was 0.033 and relative dominance was 0.208%. Where the highest Importance Value Index (INP) is on the guava tree at 43.117 and the lowest Important Value Index (INP) is in the Trichadenia tree, sp 1.3964. The distribution pattern at the tree level is based on the morista index, which is spread in groups or in clusters.Keywords: Composition, Vegetation, Nature Park

Abstract

Efforts to increase the productivity and quality of tea shoots are strongly influenced by local climatic and weather conditions at each plantation location.  The existence of climate change globally causes climate change fluctuations and weather elements in almost all tea plantation locations in the world from year to year. Determination of the local climate at each tea plantation location is important in establishing a stable and sustainable production management program and the quality of tea shoots. The weather parameters used for the determination of the start of the local rainy season (AMH) and the start of the dry season (AMK) at the tea plantation location in Tritis hamlet are the amount of rainfall and basic rainy days determined by the Meteorology, Climatology and Geophysics Agency (BMKG).  Rainfall data and local dasarian days of rain for a period of one year were analyzed using subjective descriptive methods involving graphical analysis and spatial analysis. The results showed that the beginning of the rainy season (AMH) in Tritis tea plantation was included in scenario 4 where AMH occurred in October 3 with the amount of rainfall ˃ 50 mm and the number of rainy days ˃ 6 days while the beginning of the dry season occurred in May 2 with the amount of rainfall ˂ 50 mm and the number of rainy days ˂ 6 days.Key words:  AMH, AMK, Rainfall, Dasarian, Rainy Day, and Tea Plantation.

Abstract

Onion (Allium Ascalonicum L) are one of the leading horticultural commodities that have economic value. In cultivation, Fusarium wilt disease is often damaged caused by the fungus Fusarium oxysporum. This study aimed to examine the effect of biofertilizer application on fusarium wilt disease, growth and yield of onion. The treatments tested were Bion-up biofertilizer, KIBRT, Biostimulant, Azoto-Tricho, anthracol fungicide, and without biological fertilizer as a control. Using a randomized block design with three replications. Observation variables were the incidence of fusarium wilt disease, plant height, number and weight of tubers. The results showed that the application of biofertilizers (Bion up, KIBRT, Biostimulants and Azoto-Tricho) was effective in increasing plant height, number of bulbs, and bulb weight of onion bulbs, while controlling the development of fusarium wilt disease was more effective when using Bion up, KIBRT, and Azoto-Tricho.Keywords: Biofertilizer, Antracol, Shallots, Fusarium oxysporum
