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

ABSTRACT A research on behavior of pest S. litura on two varieties of soybean has been done in Blang Manyak Village, Sawang Sub district, North Aceh District from January–May 2013. The research was arranged in a field experiment with two treatments of soybean varieties, that is Kipas Merah and Anjasmoro.  Each treatment was repeated 20 times to obtain 40 units of the experiment. Variables measured included damage intensity of S. litura, trichome density of leaves, yield components, and resistance evaluation. The relationships between yield components and damage intensity of S. litura were analyzed with regression and correlation. The results showed that damage intensity of S. litura on Kipas Merah was lower than that on Anjasmoro. Loss of soybean yield components on both varieties was influenced by the damage intensity of S. litura. There was a negative correlation between damage intensity of S. litura and soybean yield components on both varieties.  Kipas Merah was moderately resistant and Anjasmoro was susceptible against S. litura.  Resistance differences of both varieties were influenced by trichomes density of the leaves.

Abstract

ABSTRACT The research was aimed at determining suitable varieties and concentrations of compound fertilizer RapidGro 01 on growth and yield of cauliflower. Experiment was arranged in a randomized complete block design (RCBD) 3x3 with 3 replications. There were two factors studied, i.e. 1) varieties consisted of 3 levels (PM 126 F1, White Shot and Cauliflower Tropica 45 Days) and 2) concentration of compound fertilizer RapidGro 01 consisted of 3 levels (2, 4, and 6 gL-1of water). Results showed that varieties significantly affected plant height at 30 days after planting, leaf numbers at 45 days after transplanting (DAT) and wet weight of flowers per plant, but did not significantly affect plant height at 15 and 45 DAT, leaf numbers at 15 and 30 DAT, root length and wet weight. The best variety was AM 126 F1. Concentrations of compound fertilizer RapidGro 01 did not significantly affect plant height and leaf numbers at 15, 30, and 45 DAT, root length, fresh weight per plant and wet weight per plant. There was no significant interaction between varieties and concentrations of compound fertilizer RapidaGro 01 on all variables of growth and yield of cauliflower.

Abstract

The utilization of biocontrol agents as an alternative to synthetic pesticides becomes widespread as the increase of awareness to negative effects of synthetic pesticides. The objectives of this research were to isolate rhizobacteria from tomato plant rhizosphere and to characterize effective rhizobacteria isolates to deter growth of Phytopthora capsici colony. The rhizobacteria was isolated from healthy tomato plant rhizosphere, and then antagonism nature to pathogen was evaluated by double culture method. Deterrent ability of the rhizobacteria was measured based on resistance zone formed due to the presence of the biocontrol agents. Among 57 isolates, 18 were potential for further evaluation. Deterrent ability test of the 18 isolates resulted in 3 isolates which were very promising to be developed as biocontrol agents to control seed borne pathogens. They were RBBM36, RBBM18 and RBBM35.

Abstract

ABSTRACT The study was aimed at determining kinds of ameliorants that increase fertility on Hemic Peats Soil.  The experiment was arranged in a completely randomized design (CRD) with 6 treatments and 4 replications.  The result showed that the ameliorants increased pH (H2O), exchangeable cations (K, Na, Ca, Mg) and base saturation.  Sawdust had the highest ability to increase base saturation, K, and Na.  Lime had the highest ability to increase pH (H2O), Ca, and Mg.  Sawdust increased fertility hemic peats soil better than lime.

Abstract

This study was aimed at determining peanut varieties that are tolerant to drought stress and assessing the effectiveness of the use of PEG 4000 as a media simulation to drought stress.  Experiment was arranged in a Completely Randomized Design (CRD) factorial 4 x 4, repeated three times. First factor was variety, consisted of four levels, namely Tuban, Bima, Bison and Local Aceh. Second factor was PEG concentration, consisted of 4 levels, namely control, 3.5%, 11.6%, and 18.1%. Variables measured were maximum growth potential, germination rate, relative growth rate, vigor index, germination value, root length, hypocotyl length, and seedling dry weight.  The results showed that varieties exerted significant effects on maximum growth potential, germination rate, relative growth rate, root length, and hypocotyl length. PEG concentration exerted significant effects on maximum growth potential, germination rate, growth velocity, relative vigor index, germination value, root length, hypocotyl length, and seedling dry weight. There were interactions between varieties and PEG concentration on relative growth rate, root length, and hypocotyl length of groundnut seeds. Local variety of Aceh was recommended as a tolerant variety to drought stress.  Bison was not tolerant to drought stress. Bima was recommended as a moderate tolerant variety to drought, while Tuban was a tolerant variety to drought.

Abstract

ABSTRACT The purpose of this study was to examine seed viabilities of Arabica Coffee, variety Gayo 1 which was different in color of the fruits and in size of the seeds. The study was also aimed at examining interactions between fruit color and seed size on seed viabilities. Experiment was arranged in a randomized complete block design with three replications.  Factors studied were 1) fruit color consisted of three levels, namely, bright red, dark red, and yellowish green and 2) seed size consisted of large seeds, medium, small. Results showed that fruit color significantly affected germination rate, seedling growth rate, prompt germination, the time required to reach 50% germination (T50) and dry weight of normal seedlings. Seed size significantly affected germination rate, seedling growth rate, prompt germination, T50, and dry weight of normal seedlings. The best viability was found in the seeds derived from bright red fruits and small sized seeds.
