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.

Abstract

In an effort to increase the productivity of cocoa in Aceh, the government has carried out a cocoa plantation revitalization program for plants aged 25-30 years. The revitalization effort was constrained by the unavailability of quality seedlings. Alternatively, cocoa seedlings can be made available through vegetative propagations or through tissue culture techniques. Based on those facts, we have studied the inducing of callus and somatic embryos of cacao clones that were adaptive and highly productive in Aceh. The experiment was arranged in a completely randomized design, consisted of two factors. The first factor was the cacao genotype, having red and green fruits skin. The second factor consisted of six combinations of growth regulators 2,4-D and kinetin. The results showed that genotype of explants origin from cocoa red flowers responded very well in the formation of callus and somatic embryo formation. There was a significant interaction between genotype and growth regulator combinations on the explants in the number of somatic embryos formed. The best combination of concentrations growth regulator in response to somatic embryo in SCG (Secondary Callus Growth) medium was 3 mgL-1 2,4 D and 1 mgL-1 kinetin for explants from cocoa red flowers, and 1 mgL-1 2,4 D and 0 mgL-1 kinetin for explants origin from cacao green flowers.

Abstract

            Various forms of soil damage can be seen from the changes in physical properties, chemical and biological soil which happens in almost all coastal areas affected by the tsunami. The objectives of the study were to investigate the influence of organic and inorganic fertilizers in tsunami-affected lands on the growth of lettuce, and elemental content of N, P, and K in soil and plants. Experiment was carried out in polybags. Result showed that organic and inorganic fertilizer increased nutrient status of N and P soil, increased growth and nutrient content of N and P in lettuce plants. While for nutrient content of K, organic and inorganic fertilizer only affected soil and roots of lettuce. Growth and nutrient content of N, P and K in soil and plants due to organic and inorganic fertilizer application was highly dependent on the dosage given. The best growth of lettuce was obtained at combination of organic fertilizer 30 tons/ha with inorganic NPK fertilizer 1000 kg/ha
