No full textScreening 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

The experiment was conducted in Village ReuleutTimu, Sub District MuaraBatu, District Aceh Utara, from June to September 2013. The experiment was arranged in a randomized block design with three replicates. Types of mulching consisted of five levels i.e. without mulching, rice straw spread 10 tons ha-1, rice straw mulch spread 5 ton ha-1 + embedded 5 ton ha-1, sawdust spread 10 tons ha-1, sawdust spread 5 ton ha-1 + embedded 5 ton ha-1.The variables observed were soil temperature, bulk density, C-organic, N-total, C/N ratio, porosity of the soil, plant height, number of branches, leaf area, and dry weight of plants. Results showed that mulching resulted in lowering temperature, value of bulkdensity, and ratio of C/N soil, andincreasing levels of N-total, and improving soil porosity. Mulching also affected plant height, number of branches, leaf area, and plant dry weight. Rice straw provided lower degree of soil temperatures than sawdust, but did not provide better of plant height, number of leaves, leaf area and dry weight of plants. Spread rice straw provided lower soil temperature and better leaf area at 60 day after planting but lesser dry weight at 75 day after plantingthan spread+embedded rice straw

Utilization of subsoil as a growing medium for the nursery is a challenge to replace the role of topsoil as media for oil palm nurseries mainly on main nursery. This research was aimed at studying the effects of organic Guano and inorganic NPK fertilizer on oil palm seedling growth on sub soil growing media. The experiment was conducted in a pot, arranged in a randomized complete block design (RCBD), factorial 4x3 with 3 replicates. There were two factors examined, 1) guano dose consisting of four levels, namely: 0 kg, 0.5 kg, 1.0 kg and 1.5 kg/polybags and 2) inorganic fertilizers NPK consisting of three levels, namely: 0, 15, and 30 g/polybags. The results showed that subsoil can be used for growing media with applications of fertilizer Guano and inorganic NPK fertilizer. Guano and NPK fertilizer affected several soil chemical properties, i.e. increase in soil pH, available total C and N and P, and cation exchange capacity (CEC) and affected growth of oil palm seedling at age 16 weeks after planting. The best combination for the best seedling growth was obtained at 1.5 kg Guano + 30 kg NP

The purpose of this research are to examine growth capability of 5 soybean varieties and to find out is laboratory seed testing model may be use to simulate the growth capability of soybean planted at soil with salinity problem. It is expected through this research obstacle in quick screening of plant growth at saline soil being solved. This research conducted from April December 2011 at Seed Laboratory and Experimental Station of Agricultur Faculty of Unsyiah and farmer soil at Blang Krueng village, Aceh Besar. Experimental designs used in this research were Factorial CRD for laboratory and Factorial CRBD for field experiment. There are 5 varieties of soybean (Bener Meriah local seed, Kipas Merah, Kipas Putih, Anjasmoro and Orba) and 2 germination medium/soil (normal and saline) being examine, with 3 replicates, resulting 30 units experiments. Result from field experiments show that there is a significant interaction between soybean varieties and soil salinity level to seed growth capability. At normal soil, differences in varieties did not resulting in differences in seed growth capabilities, otherwise at saline soil. According to seed growth capabilities, at normal soil farmers can used any variety available, depends on production level. But, at saline soil farmers have to use Bener Meriah local seed. Whilst result from laboratory experiment did not show interaction of treatments to germination capability of soybean seed, but each treatment show its significant effect. Normal soil and Bener Meriah local seed are the best at laboratory experiment. The correlation test show that there is no close relationship between germination capability at laboratory and growth capability at field experiment, indicates that the method at laboratory cannot be use as a representative model to seed growth from field experiment
