Abstract

Land of coal post-mining is the critical area that generally can not becultivated due to very low levels of fertility of the land, so this landbecomes slighted. One of the alternatives to overcome this problem isthrough inoculation with Arbuscular Mycorrhiza Fungi (AMF).Indigenous AMF (from coal post-mining location) is more potential AMFdeveloping in that area. Therefore, isolation, identification and purificationsteps of AMF spores are required. The objective of this study was toisolate, identify, and purify of arbuscular mycorrhiza fungi from coal postmining area. The study had identified that at this soil was found 3 AMFgenuses, i.e. Glomus, Acaulospora, and Gigaspora. On coal post-miningsoil was found 20 strains of AMF (13 strains of Glomus, 3 strains ofAcaulospora, and 1 strain of Gigaspora). In this soil was dominated byGlomus. Strain’s AMF that was successful isolated from single sporeculture was 4 strains i.e. Glomus sp-3, Glomus sp-6, Glomus sp-15, danGlomus sp-16.

Abstract

In a long dried season, oil palm plant that planted in peat soil will hindered by drought stress. Drought stress is one of the main limiting factors in growth, nutrient uptake and yield of oil palm. One of the alternatives to overcome this drought stress problem on many plants is through inoculation with AMF. This research was conducted to observe the adaptability of oil palm seedling inoculated with AMF on drought stress in peat of used forest soil.  The experiment on this soil type was arranged in a Factorial Completely Randomized Design with two factors. The first factor was AMF inoculation (M0= without AMF and M1 = inoculation of AMF) and the second factor was drought stress levels (available water 100%, 75%, 50% and 25%). Research  result indicates  that AMF inoculation improved the adaptability of oil palm seedling on every level of drought stress, as shown by the responses of growth and nutrient uptake. The adaptation of non-inoculated seedling on drought stress was solely by tolerance mechanism, either osmoregulation as shown by higher production level of osmoticum components or cell turgor regulation by leaf ABA accumulation. On the inoculated seedlings, however, there were synergism between those two tolerance mechanism and escape mechanism.  Two important escape mechanisms were intensifying root system and decreasing transpiration surface of seedlings.   Key words : oil palm, AMF, drought stress, adaptation mechanism

Abstract

This research was conducted to determine the response of rubber seedlings to the application of vesicular arbuscular Mycorrhiza (VAM) and phosphorus (P). The design used in this study was completely randomized design (CRD) with two factors: VAM and phosphorus doses. The treatment is VAM doses consisting of 3 levels of mycorrhiza, that is, without mycorrhizae, 10 g/polybag , 20 g/polybag and the provision of phosphorus which consists of 5 levels i.e. without phosphorus, 25% of the recommended dose, 50% of the recommended dose, 75% of the recommended dose , 100% of the recommended dose. Each treatment was repeated 3 times so that there are 45 units of the experiment. Thevariables observed were seedlings height, seedling, diameter, total leaf area, leaf number, root dry weight, shoot dry weight, and percentage of mycorrhizal infection. The results showed that the mycorrhizal 10 g/polybag and 75% of phosphorus of the recommended dose is the best dosage on the growth of rubber seedlings.Key words : Rubber seedling, VAM, Phosphorus

Abstract

Low soil fertility is one of the main factors responsible for low productivity of tomato in Jambi Province. Soil fertility can be presumably enhanced by organic and inorganic fertilizers application. The objective of this experiment was to investigate the effect of different organic and inorganic fertilizers combination  on  plant growth and yield. One of the liquid organic fertilizer  that commonly  used     is Hantu organic fertilizer.  The research design was Randomized Block design, the treatment is organic fertilizer Hantu combined with various doses of inorganic fertilizers, 2000 ppm of organic fertilizer +  0.0 % of inorganic fertilizers, 2000 ppm of organic fertilizer + 25.0 % of inorganic fertilizers, 2000 ppm of organic fertilizer + 50.0 % of inorganic fertilizers, 2000 ppm of organic fertilizer + 75.0 % of inorganic fertilizers, 2000 ppm of organic fertilizer + 100% of inorganic fertilizers and 0.0 ppm of organic fertilizers +100% of inorganic fertilizers. Variables measured were plant height, plant dry weight, number of flowers per plant, number of fruits per plant, percentage of flowers become fruit, and fruit weight per plant. The results showed that application of 2000 ppm of organic fertilizer and 75.0 % of inorganic fertilizers showed the best growth and yield of tomato plants.      Keywords: Hantu organic fertilizer, inorganic fertilizer, tomato
