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.

Abstract

Colletotrichum gloeosporioides is a type of pathogen that causes anthracnose. This disease is classified as a major disease in chili plants which can cause great losses. Liquid smoke contains antimicrobial compounds such as phenols and acids which effectively kill and inhibit pathogenic fungi. This study aims to determine the effectiveness of coconut shell liquid smoke in controlling Colletotrichum gloeosporioides which causes anthracnose disease in chili plants. The variables in this study included the macroscopic and microscopic characteristics of the fungi, the diameter of the colony and the effectiveness of the inhibition. This study used liquid smoke types A3 (grade 3 liquid smoke self-made) A1 (grade 1 liquid smoke sold commercially) and A2 (grade 2 liquid smoke sold commercially) with different dose levels, namely, D1 (0.5 ml ), D2 (1 ml) and D3 (1.5 ml). The results of this study showed that coconut shell of A3 was effective in controlling C. gloeosporioides at treatment dose of 1 ml for each type of liquid smoke with an inhibition percentage 90%.

Abstract

The sago plant is a staple food for the people of Maluku and Papua and has many benefits and advantages to continue to be developed. A group of phylloplane microbes grow and spread on the surface of the leaves. The objective study is to find isolates of phylloplane bacteria from sago accession Makanaru and determine the inhibition of these bacteria against the growth of Rhizoctonia solani Kuhn. Sampling of sago plants (upper, middle, and lower leaves) was conducted in Negeri Seith, Leihitu District, Central Maluku Regency. Based on the isolation results, 21 isolates of phylloplanes bacteria were obtained and ready for further testing. From the results of hypersensitive test selection, 14 non-pathogenic isolates of phylloplane bacteria were obtained. Furthermore, tested the inhibitory power of phylloplane bacteria in suppressing the growth of the fungus, 3 phylloplane bacteria isolates were obtained with strong inhibitory, namely DA3.3, DT3.2, DT3.1 followed by 3 isolates DB4, DB4.2, and DB4.4 (medium inhibitory) which have the potential to be developed as biological agents.

Abstract

Farmers in the Mutiara Pattimura Farmers group are vegetable and fruit farmers from Taeno village who help with work. So far, the farmers in this farmer group have been intensively cultivating vegetable and fruit crops, including bitter gourd, long beans, kale, Chinese pumpkin, beligo (gourd), chili and basil. Bitter gourd pests need serious attention before and after planting until harvest, so assistance is needed in the form of direct surveys to farmers' fields. Preventive management of vegetable pests, especially bitter gourd through good and correct cultivation techniques, can be carried out before and after planting to manage the presence of pests in the area. The problem with PKM activities is what pests are found in the bitter melon planting area, how is the cultivation system carried out by farmers in relation to the management of bitter melon pests. Good and correct cultivation techniques before and after planting, the presence of OPT can be managed properly so that it can increase bitter melon production. Based on the problems, the following solutions are offered: Knowledge related to bitter melon cultivation techniques, Knowledge of environmentally friendly OPT control in relation to cultivation techniques. PKM activities are still deemed necessary to be carried out continuously to obtain and convey information and direct discussions with farmers so that they can provide benefits for farmers related to knowledge about pests and appropriate control measures so that optimal production can be achieved.
