Abstract

Screening genotypes of Aceh cacao to obtain resistant genotypes to Black Pod Disease (Phytopthora palmivora) is a key step. This study was conducted on basis of screening natural infection in the field and artificial infection in laboratory. The research was conducted in the field (Saree Aceh and East Aceh) and in the Plant Pathology Laboratory, Agriculture Faculty, Syiah Kuala University. The study started from March to November 2013. Results from the field and laboratory, based on artificial inoculation, showed that three genotypes originated from Saree Aceh i.e. SR 26, SR 40 and SR7 were resistant, indicated by the characters of long incubation period (more than five days), a small diameter of spot, slow growth of the spot, and low percentage of symptoms. The three genotypes had both a good wounded post-penetration and unwounded pre-penetration resistance. Conversely, cacao genotypes originated from East Aceh did not show a significant difference of post-penetration resistance.

Abstract

The use of superior seeds and certified hybrids is one of the efforts to increase the productivity of chili. Absorption of nutrients and water is strongly supported by root growth, with the administration of Trichoderma sp. hence root growth becomes better so that the process of absorption of nutrients and water will also be optimal which also results in the growth and production of chili plants. This study aims to determine the effect of varieties and dosages of T. harzianum pellets as well as their interactions with the growth and production of chili. The design used in this study was a factorial randomized block design (RBD) with 3 replications. The results showed that the treatment of varieties had a very significant effect on the average plant height and canopy width at 20, 40, and 60 DAP, wet stover weight, dry stover weight, fruit length and fruit diameter. Varieties have a significant effect on leaf length, and root length. The growth and production of chili plants is better found in the Lado variety. The dose of T. harzianum has a very significant effect on the average root length and has a significant effect on the average weight of dry stover. The better growth and production of chili plants is found in the administration of 20 g of T. harzianum / plant.

Abstract

                      Cacao is an important plantation plant in Indonesia for its contribution to our income.  The productivity of this plant still have a chance to be increased, with the improvement in culture technique. One limited information concerning the cacao cultivation technique is seedling ages and urea dosages when transplanting. The purposes of this research were to find out the effect of seedling ages, urea dosages, and interaction between them on cacao seedling growth at nursery. Research was conducted at Experimental Station of Agriculture Faculty, University of Syiah Kuala. Units of treatment were arranged according to Factorial Randomized Complete Block Design with 4 replicates, followed by Honestly Significant Different Test at the level of 5%. Seeds were extracted from 1/3 of cacao mature fruits at the center of the pod and germinated in germination box filled with sand and covered by wet towel. Growing medium used was top soil:manure:sand=2:1:1 (by volume). Variables observed were seedling height, stem diameter, leaf number and area, primary root length, and wet and dry mass of seedling at 45, 60 75 and 90 days after transplanting. Results showed that there were significant  interactions between treatments on all variables observed. The best combination was age of 10 days of seedling and dosage of 2 g urea per polybag.

Abstract

MOL (Local Microorganism) is one of the key factors to determine the success in manufacturing of organic fertilizer. MOL can fully substitute EM4 (Effective Microorganism) widely being sold in market, as starter to accelerate composting process. The MOL in the experiment was produced from agricultural waste likes in consumable fruits. The experiment was aimed to investigate a better fermentation method in the production of MOL. A Split Plot Design with fermentation methods (with and without applying of air channel) as main plot and length of fermentation (0, 1, 2, 3, 4 and 5 weeks) as sub-plot were applied to produce MOL, with 2 replications. With air channel, the gas produced from the fermentation process could be channeled out of the fermentation container. Analysis of MOL quality included total microorganisms (TCC), temperature, pH, and color. In general, result showed that the MOLs produced from fermentations without air channel were better than the ones produced from with air channel. The highest amount of TCC in MOL was produced from 3 weeks fermentation without air channel.

The Aplication of PaddyHusks As An Alternative  Medium and  Test of Efectivity Of Foliar Fertilizer on Growth and Yield of Tomato In Hydroponics ABSTRACT             A research of using various media and fertilizers on tomato planted hydroponically has been conducted in the green house of Agriculture faculty, Syiah Kuala University, Banda Aceh, starting from July to November 2002. The objective of research was to observe the influence of various media and fertilizer, as well as the interaction of each other to the growth and yield of tomato planted hydroponically. The treatment composed of two factors, namely various media (paddy’s husks / kuntan, sands, and mixture of  kuntan and sands) and fertilizers (Vitamon, Bayfolan, Complesal and Hoagland solution). The research was assigned in completely randomized design in a factorial manner, consisting three replications. The results showed that the best growth and highest yield of the tomato were found in the mixture medium (kuntan + sands). These results were significantly different from those of the single medium. The use of Hoagland solution resulted on the best growth and highest yield of tomato which were not significantly different from those of Bayfolan and Complesal Fertilizer. It is observed that there were no significant interactions between the two factors tested.
