Abstract

        The study was aimed at determining responses of several sweet corn varieties to organic and inorganic fertilizers on tsunami affected land and knowing interactions between both factors on growth and yield of sweet corn. The experiment was conducted in Village of Lampuuk, Lhoknga, District of Aceh Besar, from January 7 to March 19, 2008. This research was conducted using a randomized complete block design (RCBD), 3 x 3 with 3 replications. There were two factors studied, namely fertilizations, consisting of 3 levels: 100% organic fertilizer, 50% organic fertilizer + 50% inorganic fertilizers and 100% inorganic fertilizers. The second factor was varieties, consisting of 3 levels: Sweet Boy, Hawaiian Sweet Corn Hybrid F1 and Super Bee. The results showed that fertilization significantly affected ear weight with and without cornhusk, but did not affect diameter of ear and seed rows per ear. The highest result was found at a treatment of 50% organic fertilizer + 50% inorganic fertilizers, but was not significantly different from 100% organic fertilizer. Varieties showed no significant effects on all variables observed.  There were significant interactions between fertilizations and varieties on plant height at age 42 and 63 day after planting (DAP), leaf length at age 21, 42, and 63 DAP, and root fresh weight at age 21 DAP.  The best plant growth was found at a combination of Sweet Boy   and 50% organic fertilizer + 50% inorganic fertilizer.

Abstract

Land Suitability for Horticultural Crops on Areal of Ex-Peat Swamp Forest of Nagan Raya Districts, Aceh Province Abstract. The conversion of peat swamp forests into farmlands can potentially change the soil’s characteristics and morphology, which in turn will affect land suitability. This research was performed to assess the land suitability level for the development of horticultural crops in a former peat swamp forest area which covers an area of 2732,12 ha in Darul Makmur Sub-district, Nagan Raya Regency, Aceh Province. The research was conducted using the descriptive method through ground surveys and laboratory analyses. The land suitability for horticultural crops evaluation was accomplished using the FAO criteria, which is matching between the land criteria and growing requirements for each horticultural crop. The evaluated lands were grouped into five homogeneous land units (HLU). The results indicated that every former peat swamp forest that has been converted into farmland had a land suitability level of S3, wa (marginally suitable) for several horticultural crops, such as pineapples, melons, eggplants, tomatoes, spinaches, red chili peppers, cucumbers, long beans, and watermelons. The main limitation factors were high rainfall and nutrients retention. The results also showed that mustard greens and shallots had a land suitability level of N (not suitable) because of the high rainfall.

Abstract

Composition and Community Structure Hymenoptera Parasitoid Garden Maintained by Conventional and Organic Coffee In District Aceh TengahABSTRACT. This study aimed to obtain scientific information about the species or group of parasitoids associated with habitat, so as to build a database for the purposes of pest management in the future. This research was conducted in coffee plantations in Central Aceh District and continued identification in Pest Laboratory, Faculty of Agriculture UNSYIAH from June to November 2014. This study used a survey method. Insect sampling done by purposive sampling method on coffee plantations were managed conventionally and organically. Abundance of individuals, the number of families and species richness highest Hymenoptera encountered in the practice of organic farming over conventional coffee. Hymenoptera parasitoids composition of coffee plantations are managed organically composed of 13 families, while the coffee plantations were managed conventionally only 7 families. However, Hymenoptera parasitoid community structure on both habitat types are relatively the same because it is dominated by the families Braconidae and Ichneumonidae.

Abstract

            The objectives of this research were to study effects of cutting internode numbers and urea dosages, and interaction between them on pogostemon bud cutting growth. This research was done at Kajhu Village, Baitussalam Sub District, Aceh Besar District, Aceh Province, from February 15th to April 15th 2011. Experiment was arranged according to Factorial Randomized Complete Block Design 3 x 3, with 3 replicates. Each of replications was consisted of 3 plants, resulting 81 experimental units. The first factor was cutting internode numbers, consisted of 3 levels, i.e. 2, 3 and 4 internodes. The second factor was urea dosage, also consisted of 3 levels, i.e. 1, 2 and 3 g urea/cutting. All cuttings were planted in polybags; one cutting per polybag, filled with 5 kg of soil, with one internode was inserted into the soil. The result showed that there were highly significant interactions between cutting internode numbers and urea dosages on pogostemon cutting leaves and bud numbers at 60 days after planting, which means that cuttings with different internode numbers responded differently to urea dosage increases. The best one was cutting with 4 internode numbers and the best urea dosage was 2 g/cutting.  The best combination was cutting with 2 internodes and 2 g urea/cutting.
