Abstract

Fungus Stigmina myristicae causes rot dried fruit disease and pest Batocera herculesstem borer on nutmeg plants are found in Central Maluku, Province Maluku as the cause of plant damage nutmeg. Surveys in the District Laitutu Maluku Central was conducted in August 2014 with the aim to determine the intensity of the large and spacious dried fruit rot disease and stem borer, and the greater the intensity of dried fruit rot disease on various strata in the nutmeg crop. The results showed that the intensity of dried fruit rot disease is more prevalent in the nutmeg in the middle and lower strata of plants reached 1.42% and 2.09%, and in general to be 1.24%, while the area of the attack reached 23.90%. The intensity of the attacks stem borer reaches 1.76% and spacious attacks reached 0.56%. These results indicate that the nutmeg crop damage by Stigmina myristicae and Batocera hercules classified low category.Keywork:Stigmina myristicae, Batocera hercules,Nutmeg, Stem borer, Dried fruit rot.

Abstract

Trichoderma harzianum as a potential biological agent and are widely used to control diseases in various agricultural crops and plantations. This research goal of getting the best growth of Trichoderma harzianum on molasses-based liquid medium. The treatments tested was added 0.05%, 0.1% and 1% liquid pure culture of Trichoderma harzianum each in 500 ml of sterile liquid medium containing 5% molasses (v/v) and 5% commercial yeast (b / v), and incubated for five days. The results showed that Trichoderma harzianum growth with the highest number of spores occur if the molasses-based liquid medium supplemented with 1% Trichoderma harzianum.

Abstract

The use of biofertilizers is important to prevent the negative impact of the synthetic fertilizers in vegetable production.  This study aimed to determine the effect of single biofertilizer  Azotobacter, and consortial biofertilizer which consist of nitrogen fixer bacteria and pohosphate solubilizing bacteria on the growth and yield of green cabbage (Brassica juncea L). The experimental designed was  randomized block design with five replications. Green cabbage seedling were inoculated with biofertilizer Azotobacter and consortial biofertilizer  on the growth and yield of green cabbage. Plants with consortial biofertilizer showed better growth and yield than that received single biofertilizer. Consortial biofertilizer  can increase plant height and shoot fresh weight up to 15.68 % and 17.05 %, while those with  Azotobacter  were 7.77 % and 9.58 % consecutively, compared with plants control.

Abstract

Choy sum (Brassica rapa L.) cultivation main obstacle in Maluku was soil fertility and plant diseases. Biological agent and Biofertilizers will play a significant role to reduce the intensity of disease attacks, and increase crop productivity. The objective of this experiment  was to study the effects of nitrogen fixing and phosphate solubilizing microbe (Bion-UP) and Trichoderma harzianum solid inokulan (Bokelas Plus) on choy sum productivity grown on land Rhizoctonia solani-contaminated land. The experimental treatments  were liquid  biofertilizer and Bokelas Plus which has been combined into 6 treatments: Without biofertilizer and Bokelas Plus, 50 kg Bokelas Plus/ha without biofertilizer, 15 mL biofertilizer per plant without Bokales Plus, 15 mL biofertilizer per plant + 50 Kg Bokelas Plus/ha, 15 mL biofertilizer  per plant + 25 kg Bokelas Plus/ha, and 7.5 mL biofertilizer per plant + 50 kg Bokales Plus/ha. The results showed that giving of Bokelas Plus and biofertilizer with different dose levels decreased  leaf blight intensity and increasing fresh weight of choy sum. Biofertilizer application with and without Bokelas Plus decreased the intensity of leaf blight disease by 39.14% - 46, 93%, and increase the fresh weight of choy sum by 15.19% - 36.25%.

Abstract

Leafy vegetables contributes to the inflation rate in Ambon City due to low productivity in rainy season. Some vegetables are imported from other islands while importantvegetables such as local petsai (Brassica chinensis L.) and chili (Capsicum annum L.) are cultivated in low nitrogen soil, Entisols. Lack of nitrogen could be overcome by using inorganic fertilizeras well as biofertilzer. The soil can be inoculated with rhizobacteria, such as Azotobacter, to increase  the nitrogen uptake and improve the quality of vegetables. This research was conducted to isolate and select Azotobacter from rhizosphere of vegetables and to examine the effect of Azotobacter inoculation on chili-seedling growth and nitrogen uptake by using bioassay method. Azotobacter sp. was isolated in nitrogen-free Ashby’s Media. The bioassay was held in the green house with randomized block design experiment, which examined the combination of isolates and population of Azotobacter sp. on chili. Two best isolates which was selected based on pH, nitrogen content and cell viability were s2a10 (from petsai's rhizosphere) and c2a9 (from chili’s rhizosphere). Bioassay showed that Azotobacter inoculation followed by reduced NPK fertilizer doses had no effect on transplant dry weight and nitrogen uptake. All Azotobacter 8 -1inoculation except  10 CFU mL s2a10 maintain soil nitrogen although Azotobacter population in soil was slightly reduced. This showed that Azotobacter sp. potentially reduce the use of inorganic biofertilizer.
