Abstract

The objectives of this research were to estimate responses of several sweet potato genotypes in preservation media through in vitro slow growth preservation, and to achieve cheap and accessible media. Experiment was arranged in a completely randomized design with a single factor. The experimental factor was sweet potato genotype (Sukuh, 421.34,343.15 and 2040.8). These genotype were tested in a preservation media which consisted of 15% coconut water +  30 mg/l aspirin + 50 g/l sucrose + 7 g/l agar. Experiment was replicated four times. Data was analyzed parametrically and non-parametrically. The result showed that genotype gave high responses to preservation media. Genotype Sukuh produced highest leaves while genotype 421.34 yielded highest numbers of root and internode. In the preservation medium of Genotype Sukuh through in vitro slow growth preservation, aspirin could be added to inhibit growth by increased leaf senesence. This experiment also showed that Hiponex (20:20:20) could be used as the basic media for in vitro preservation of sweet potato

Abstract

Solid waste management is an old problem in urban areas.  High population growth rates have caused the increasing amount of wastes generated. One of the efforts to solve the problem is to recycle the organic wastes by composting. The purpose of this research was to find out the influence of effective inoculants PROMI and EM4 on decomposition rate and compost quality from municipal waste in Ambon. This research used a Completely Randomized Design (CRD) in single factor experiment using 2 effective inoculants, i.e. PROMI (no Promi = P0, 24 gr Promi/10 kg organic waste = P1, 48 gr Promi/10 kg organic waste = P2) and EM4 (no EM4 = E0, 150 ml EM4/10 kg organic waste = E1, 300 ml EM4/10 kg organic waste = E2). The treatments consisted of the 2 types of inoculants with 3 dosages of each, and 3 replications. The result showed that the addition of effective inoculant EM4 with a dosage of 300 ml per 10 kg organic waste (E2) was more effective compared to the other treatments in accelerating the decomposition rate in 28 days. This was supported by decomposition rate indicators, such as compost physical characteristics, C/N ratio (11.56), and the increased compost quality, such as pH (8.03), Nitrogen (2.91%), Phosphorus (141.33 mg per 100g P2O5), Potassium (553.67 mg per100g K2O). This compost was in accordance to Indonesia National Standard (INS) or Standar Nasional Indonesia (SNI) of organic manure No. 19-7030-2004.

Abstract

Nitrogen is a major nutrient for plant growth, nitrogen was absorbed by plant roots in the form of NO3-(nitrate) and NH4+ (ammonium). Nitrogen deficiency affects negatively on plants, like stunted plant, leaf turns yellow, and limited rooting system, while excess nitrogen causes elongated vegetative growth, easy to fall down, reduce the grain quality and its response to pests and diseases. The purpose of this study is to determine the available soil-N, plant N uptake and growth as well as the yield of paddy rice (Oryza sativa L) due to the treatment of straw compost and NPK fertilizer. Treatment was carried out in a factorial experiment designed in randomized block design, the straw compost factor consisted of  two dose levels: 0 and 3.0 ton ha-1 and NPK fertilizer factor consisted of five dose levels: 0, 75, 150, 225, and 300 kg ha-1 with three replications. Research findings indicated that the amendment of straw compost together with NPK fertilizer increased the plant uptake of N, but straw compost improved independently the soil-N, and plant growth (plant height and number of tillers/clump). Likewise, NPK fertilizer independently increased soil-N, growth parameter (plant height and number of tillers/clump) and grain yield (number of grains/panicle and number of filled grain/panicle). The straw compost amendment at 3 tons ha-1 along with 150 kg NPK ha-1 resulted the highest N-uptake of 3.51%.

Abstract

The use of biological agents to prevent the growth of plant diseases is aimed at decreasing the capability of particular pathogen, preventing their growth and spread, reducing the infection and intensity of pathogenic attack to main plants. Trichoderma harzianum is commonly found in almost all types of soil, and is one of fungi that can be used as biological agents to control plant pathogens.  Growth and development of this fungi are mostly influenced by factors such as temperature, light, air, and pH.  It is also dependents on other nutrients such as carbon, nitrogen and plain carbohydrate which are contained in sago waste (ela), bran and rice husk. The objective of this study is to find out the utilization of sago waste, bran and rice husk as media to multiply the biological agents T. harzianum. The result of this study showed that sago waste compost could  be used as a medium to multiply the antagonist T. harzianum; when appropriately mixed with bran and rice husk (1:1:1 v/v), sago waste composts would be an effective media to develop the T. harzianum fungus. This mixture is better compared to sago waste composts, husk, sago waste composts and bran, and sago waste composts and husk. It is doe to the fact that in the media number of spore of T. harzianum (7,08 x 109/mL) increased and colony characteristics was dense..

Abstract

Maluku in general and Ambon municipality in particular is a region with the lowest peanut production as compared to its national production. Cambisol is one of soil type that has good soil physical properties, but it is low in N and P contents and has an acidic reaction that inhibit the growth of peanut plants.  The research was conducted in a plastic house in Halong Village, Teluk Ambon Baguala Subdistrict, from April to Juli 2012. This research used a Completely Randomized Design with two factors, i.e. factor 1 with three levels of dolomite fertilization, consisting of D0 (without dolomite), D1 (0.3g dolomite per pot), D2 (0.6 g dolomite per pot), and factor 2 with three levels of phosphate fertilization consisting of P0 (without phosphate fertilizer), P1 (0.7 g SP-36 per pot) and P2 (1.4 SP-36 per pot). The results showed that the application of SP-36 increased the number of root nodules and yield of peanut. Response was even better if accompanied by the application of dolomite. Leaf N uptake could be enhanced by application SP-36, but it was independ from the application of dolomite. The highest peanut yield of 41.83 g per pot was achieved with the fertilizer combination of D1P2  (0.3 g dolomite per pot and  1.4 g SP36 per pot)
