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

            The research was aimed at determining effects of organic fertilizer D.I Grow and inorganic fertilizer  NPK Yara Mila on growth and yield of soybean.  The experiment was arranged in a completely randomized (CRD) 4 x 4 with 3 replications. There were two factors observed, that were 1) concentration of organic fertilizer D.I Grow, consisting of 4 levels : 0 mL/L of water, 1 mL/L of water, 3 mL/L of water and 5 mL/L of water, and 2) inorganic fertilizer NPK, consisting of 4 levels : 0 g/plant, 2,5 g/plant, 5,0 g/plant and 7,5 g/plant. Results showed that the concentration of fertilizer D.I Grow exerted highly significant effects on dry seed weight per plant,  yield potential,  and significant effects on plant height at 30 and 45 days after planting (DAP),  stem diameter at 45 DAP, and seed dry weight of 100 grains,  but did not exert significant effects on plant height at 15 DAP and stem diameter at 15 and 30 DAP. The best growth and yield were obtained at a concentration of DI Grow 5 mL /L of water. NPK fertilizer significantly affected plant height  at 45 DAP, stem diameter at 30 and 45 DAP, dry seed weight per plant,  and yield potential, but  did not significantly  affect plant height of 15 and 30 DAP,  stem diameter at 15 DAP,  weight of 100 grain   and seed dry weight of 100 grains. The best growth and yield were obtained at a dose of 7.5 g NPK/plant. There were highly significant interactions between concentration of D.I Grow and dosage of NPK on dry seed weight per plant and  yield potential. The best yield was obtained  at a combination of D.I Grow 5 mL/L of water and 7.5 g of NPK plant .

Effect of the Pod Hardness Level and Seed Position in Pod on Cocoa Seed (Theobroma cacao L.) Viability and Vigor ABSTRACT. The study was aimed to recognize the effect of the pod hardness level, seed position in pod, and the interaction between them on cocoa seed viability and vigor. The design used was a factorial completely randomized design (CRD) with 3 replicates. The level of pod hardness as the first factor consisted of 4 levels: > 3.5 kg/second, 3.0 < K ≤ 3.5 kg/second, 2.5 < K ≤ 3.0 kg/second and 2.0 < K ≤ 2.5 kg/second. The position of seed in pod as the second factor covers 3 levels, they are both ends and the middle of the pod. Observation conducted to the seed dried weight (BK), maximum growth potency (PTM), germination capacity (DB), vigor index (IV), growth speed (KCT), simultaneity growing (KST), time needed to reach 50% from the total of relative germination (T50) and dry weight of normal sprouts (BKKN). The results showed that the highest viability and vigor of cocoa seed was found from 2.5 < K ≤ 3.0 kg/second of pod hardness level. The highest viability and vigor of cocoa seed came from the middle of the pod. The best combination was found from 2.5 < K ≤ 3.0 kg/second of pod hardness level in the middle of the pod.

Abstract

The research objectives were to study relationships between soybean seed vigor in laboratory and seed growth in field.  The research was carried out in Laboratory Seed Science and Technology and Seed Experimental Farm of Agriculture Faculty, University of Syiah Kuala, Darussalam Banda Aceh. Experimental design used was a completely randomized design (CRD) 2x5 with 3 replications in the laboratory and a split plot design with 3 replications in the field. The factors examined were soybean varieties and oxygen. The varieties were consisted of Pandermau S-37, Local of Bireuen, Wilis, Orba, local of Tasikmalaya. The oxygen was consisted of 2 levels, i.e. oxygen stress and normal oxygen. Variables observed in the laboratory were seedling growth rate and dry weight of normal seedling, while in the field were soybean growth rate and dry weight of plant.  Results showed that growth of the five varieties on the field of oxygen stress can be simulated through examination in laboratory. Of the two variables observed, seedling growth rate was more sensitive for the purpose. On the other hand, dry weight of seedling was less precise for simulating that condition.

Abstract

Performance of Red Rice Genotype from Aceh’s Province that Cultivated with Aerobic System in Organic SRI ABSTRACT. Characterization of the performance on morpho-agronomic brown rice originating from local varieties of Aceh has been done in order to develop new varieties that adapt to climate change and suitable for organic SRI method. Eighteen red rice genotypes have been planted to evaluate the characters based on the method of cultivation in aerobic system. The red rice genotypes were observed and showed the variation in very significant to the formation of tillers, plant height, number of panicles, panicle length, grain weight per plant, 1000 grain weight, and grain yield potential. The results showed that the genotypes studied had high genetic diversity. Tillering in red rice varies between 19-30 days after sowing. The highest plant height found in genotype Pade Mirah 44, while the lowest plant found in genotype Sipulo Mirah. It was dicovered that the number of panicle significantly affected by the red rice genotype. Number of red rice panicle ranged between 14-48 per plant. The number of panicles in genotype Ketan Mirah was higher than genotype of Meuligai Mirah. However, Ketan Mirah 2 had the shortest panicles. Grain weight per panicle significantly also affected by red rice genotypes. The highest grain weight found in genotype Pineung Lango 172. In addition, also found that the weight of 1000 grain red rice was significantly different between the genotypes. The smallest size of a grain found in genotype of Sirias 102, whereas genotype Pade Mas 41 showed the largest size of grain (30.8 g). Research showed that genotypes affect grain yield potential significantly. The highest yield potential obtained from the genotype Pineung Lango 172 (6.8 ton/ha). In contrast, the lowest result was found in genotype Sipulo Mirah (2.8 tons/ha). Therefore, the results of the present invention is expected to provide information to enhance the sustainability of rice plant breeding system of organic red rice according to SRI system.
