Abstract

Pathogens often cause disease in plants, causing losses both in quality and quantity, and frequently can cause death on plants cultivated. Biological control begin to be selected in control of pathogens. Antagonist agent Trichoderma is known to control fungal pathogens causing plant diseases. This study looked over inhibition effects of Trichoderma sp. against pathogenic fungi; C. capsici, Fusarium sp. and S. rolfsii. This research was conducted at Laboratory of Plant Pathology Faculty of Agriculture, Syiah Kuala University from April to August 2012. The study began with isolation of the pathogen obtained from chili and soybean crops infected in the field.. Pathogenic fungi isolated were Colletotrichum capsici, Fusarium sp. and Sclerotium rolfsii. Variables observed were wide and diameter colony of Trichoderma sp., diameter colony of pathogens, and the percentage of inhibition. The results showed that Trichoderma sp., had ability to inhibit the growth of pathogen Colletotrichum capsici, Fusarium sp. and Sclerotium rolfsii  in vitro. The highest percentage of inhibition of Trichoderma sp. was 68,2% against Colletotrichum capsici, followed by 53,9% against Fusarium sp., and the lowest inhibition was against Sclerotium rolfsii (35.5%).

Abstract

Fermented durian is the fermented food prepared from spontaneous fermentation of durian (Durio zibethinus L) with or without salt by wild bacteria. Fermented durian is found not only in Indonesia  as long as Sumatera island with the different names, but also in Malaysia. The sources data in this study was laboratory analysis. Productions center of fermented durian, traditional markets were sampled for the experiment. Sampels were collected every week in a month. Samples were analyzed microbiologically to determine and identify bacteria in fermented durian. There were two species of bacillus bacteria involved in fermented durian namely  Lactobacillus plantarum and Lactobacillus curvatus. The specieses were  included in lactic acid bacteria.Lactic acid (C2H5COOH) is the organic acid that  can serve as a food preservation. The group of bacteria which can produce lactic acid in their fermentation process known as Lactic Acid Bacteria (LAB). A fundamental biochemical change of fermentation is that an acidic environment is created. Many harmful organisms cannot exist in acidic solution so the fermentation productions are save to eat.

Abstract

            The objective of study was to determine response of three varieties of rice to timing of providing organic fertilizer on SRI system. The results showed that the timing of providing organic materials exerted a significant effect on grain weight per hill and production per hectare, but no significant effect on variables of other rice growth and production. Provision of organic matter at planting date and a week after planting date gave  better grain weight per hill and production per hectare than a week before planting date. These results were consistent for all the tested rice varieties, i.e. Ciherang, Pandan Wangi, and Angke.  However, to some extent, Pandan Wangi was the best.

Abstract

The objectives of this research were to assess effects of varieties and hydrocarbon-contaminated growing medium on seed vigors of corn and interactions between the two factors mentioned. The experimental design used was a completely randomized design 3 x 4 with three replications. The first factor was varieties, consisting three varieties, namely, Pertiwi 3, Manise, and Bonanza F1.  The second factor was hydrocarbon-contaminated growing medium, consisting four levels of  hydrocarbon (crude oil) concentration i.e. without crude oil,  5 ml crude oil/liter water,  10 ml crude oil/liter water  and  15 ml crude oil/liter water.  The result showed that some varieties significantly affect potential of seed growth, seed germination, rate of germination, vigor index and seed germination uniformity. However, concentration of hydrocarbon did not significantly affect all parameter observed.  There was significant interaction between varieties and concentration of hydrocarbon on potential of seed growth, seed germination uniformity and T.50.

Abstract

ABSTRACT The objective of this study was to examine hexagonal plant spacing on growth and yield of three varieties of rice. In addition, this study was also aimed to examine interactions between the hexagonal plant spacing and the varieties on growth and yield of rice plants.  The experiment applied a split plot design with four replications. Factors studied were (1) variety, placed as a main plot and (2) hexagonal plant spacing, placed as subplot. The results showed that effect of plant spacing on productive tiller number varied, depending on variety. In Pandan Wangi and Ciherang varieties, productive tiller numbers did not differ between plant spacing of 21 cm from a spacing of 25 cm. In contrast, in line Cot Irie, productive tiller of 25 cm plant spacing outnumbered that of plant spacing of 21 cm. Effect of plant spacing on panicle length was consistent on all varieties tested. Rice panicle length did not differ between plant spacing of 21 cm and 25 cm. Effect of plant spacing on potential yield per hectare was also consistent across all varieties tested. Plant spacing of 21 cm provided a potential yield per ha which was not significantly different from plant spacing of 25 cm. Line Cot Irie provided panicle length better than varieties Pandan Wangi and Ciherang. Line Cot Irie also provided the highest yield potential per hectare, while panicle length and potential yield per ha of Ciherang were not significantly different from Pandan Wangi.

Abstract

Effect of Water Stress at Two Types of Soil on Growth and Yield of Soybean  (Glycine max (L.) MERRIL) Nurhayati Fakultas Pertanian Unsyiah, Darussalam Banda Aceh ABSTRACT  This study was aimed at determining effect of water stress maintained at 100, 80, 60, and 40% of field capacity in ordo Entisol and Ultisol on growth and yield of soybean. Experimental design used was a completely randomized design, 4 x 2 with three replicates. Results showed that water stress significantly affected all components of growth and yield of soybean, as well as amount of cumulative water need of soybean at plant ages of 8 - 95 days. Soil type also significantly affected all components of growth and yield of soybean, as well as amount of cumulative water need of soybean, except root length.  The best growth and yield of soybean was found at ordo Entisol. There was a highly significant interaction of all components of soybean growths and yields, except plant height at the age of 15 and 30 days after planting.  Soybean was still capable of producing high yield at the range of water stress 60% - 80% of field capacity in ordo Entisol, whereas in ordo Ultisol at the same circumstance, the soybean was not capable of maintaining the yield.

Abstract

This study was aimed at determining the appropriate growing medium composition and foliar fertilizer concentration and their interaction on growth and yield of lettuce. The experiment was arranged in a randomized complete block design (RCBD), consisting of two factors, i.e. the growing media composition and foliar fertilizer concentration. The first factor consisted of the composition of the soil and manure by volume ratio (3:1, 3:2, and 3:3) and the second factor consisted of foliar fertilizer concentrations (0, 2, 4 mL/L of water ). The results showed that the growing media composition soil+manure (3:3) was the best in increasing crop height, leaves number, leaf length, leaf width and yield at 35 day after planting, while the best concentration for those parameters was 4 mL/L of water. Based on the interaction, the best leaf number of lettuce was found at growing media composition soil+manure (3:3) with the concentration of foliar fertilizer 4 mL/L of water.
