Abstract

This study aims to determine the interaction between multiple inoculations of Arbuscular Mycorrhizae and non-symbiotic N-fixing bacteria Azosprrillum at different urea fertilizer dosages on physiological processes and N, P uptake in peat soils. The study used a factorial design of 4x4 completely randomized layout with 3 replications. The first factor is the inoculation of Arbuscular Mycorrhizae and Azospirillum lipoferum (M) consisting of 4 levels, namely m0 (without inoculation), m1 (Arbuscular mycorrhiza inoculation), m2 (Azospirillum lipoferum inoculation) and m3 (inoculation with Arbuscular Mycorrhiza and Azospirillum. lipoferum). The second factor is the dose of urea with 4 levels, namely n0 (without urea fertilizer), n1 (urea urea recommended dose), n2 (½ recommended dose) and n3 (recommended dose). The dose of urea for maize is 150 kg ha-1. The data obtained were analyzed statistically using analysis of variance (F test), if the F test showed a significant difference between each treatment and interaction, it was followed by Duncan's multiple distance test at the 5% level. Observations were made on N and P uptake, Net Assimilation Rate (LAB) and relative growth rate (LPN). The results showed that the double inoculation of Arbuscular Mycorrhizae and Azospirillum lipoferum was effective at all doses of urea in increasing nutrient uptake of N and P.

Abstract

Shallot is a leading horticulture commodity in Indonesia that has long been intensively cultivated. Soil preparation by increasing soil fertility are technologies that can be applied to increase shallot yield. This study aims to determine the effect of the combination of organic matter and ZA fertilizer using the double digging method on the growth and yield of the ‘Lembah Palu’ variety shallots. This research was conducted in Sintuwu Lemba Village, Lage District, Poso Regency from February to June 2020. The study used a factorial randomized block design which consists of two treatment factors. The first factor was the use of organic matter (without organic matter, gliricidia leaves (Gliricidia sepium), banana stems, and rice straw) and the second factor was the dose of ZA fertilizer (without ZA and 400 kg/ha). This study concluded that there was a significant interaction between the types of organic matter and ZA fertilizer dosage in the double-digging method. The application of rice straw without ZA fertilizer in the double digging method gave the highest yield of 2.82 tons/ha. Rice straw as the organic matter gave the highest average growth and yield of shallots although they were not significantly different from gliricidia leaves and banana stems. The application of ZA fertilizer had no significant effect on the growth and yield of shallot.

Abstract

Aphis gossypii Glover (Hemiptera: Aphididae) is a polyphagous insect that can attack various types of plants. Its presence on chili plants can cause significant yield losses. In addition, this aphid also acts as a vector for viruses that can attack chili plants. Control of aphids is generally done using synthetic pesticides, but the use of these pesticides can have a negative impact on the environment and human health. As an alternative, plant-based insecticides can be used to control these insects. One plant that has potential as a plant-based insecticide is gigantic swallow wort (Calotropis gigantea Linn.). Gigantic swallow wort leaf extract contains secondary metabolites such as flavonoids, terpenoids, alkaloids, and others that have toxic effects on aphids. This study aims to analyze the effect of gigantic swallow wort leaf extract on the mortality of chili aphids. The research method used a completely randomized design with five treatments of gigantic swallow wort extract concentration, namely 0%; 0.5%; 1%; 1.5%; and 2%. The test was conducted by spray method, and the mortality of aphids was observed for three days. The highest mortality was found in the 2% gigantic swallow wort extract concentration treatment with a mortality percentage of 76.67%. Based on literature studies, the presence of secondary metabolite compounds such as alkaloids, glycosides, terpenoids, flavonoids, and others. These compounds are thought to have an insecticidal effect and can interfere with the metabolism of aphids. The use of plant-based insecticides can be an alternative that is more environmentally friendly and safe for non-target organisms. In addition, this study also provides information on the content of secondary metabolites in biduri extract that play a role in controlling pests.

Abstract

ABSTRACT Lentinula edodes (shiitake) is one of the most produced mushrooms in China. Not only famous with its medicinal value but also with its unique taste. Shiitake’s growth and fruit body formation influenced by many factors including biological, chemical, and physical factors. Virus infection in mushroom especially in shiitake is a relatively new. Whether virus infection caused severe disease or just reside inside basidiocarp and mycelium without causing any abnormality or physiological change are still unclear. This research was conducted to discover is there any relationship between abnormal fruit body with virus infection. Study used molecular genetics method to prove relationship between them. RT-PCR conducted to prove which sample contain the virus, BLAST sequence result showed that there is no significant similarity found with other sequences in NCBI data. Because of very low quantity of virus, unsuitable primer used to detect viral sequence, or new sequences of viral material genetic that has not registered in NCBI. Many factors influence the formation of fruit body including genetic and environmental factors. Abnormalities maybe caused by environmental factor while virus infected shiitake were not discovered. Keywords: abnormal shiitake basidiocarp; shiitake mycovirus; cultivate mushroom

Abstract

Acid dry land has the opportunity to be developed either through intensification or extensification programs. Opportunities for intensification are still open, because the average production level achieved has not been optimal. Soybean (Glycine max L) is one of the main legume commodities which is a national mainstay because it is the most popular source of vegetable protein for Indonesian people in general, for food diversification in supporting national food security. Practical steps to increase soybean productivity can also be through the efficient use of fertilizers, both organic and inorganic fertilizers. This experiment was carried out from July to October 2018 at the YAPETRI (Peruri Pension Foundation) Garden, which is located in Sapta Marga Hamlet RT.07 RW.03, Sinarbaya Village, Telukjambe Timur, Karawang. The research method used was an experiment with a factorial Randomized Block Design (RBD). The first factor is the type of soil enhancer which consists of 3 levels, namely straw organic fertilizer, organic waste fertilizer and bottom ash. The second factor was the dosage of Phonska fertilizer consisting of 4 levels (100% NPK, 75% NPK, 50% NPK and 25% NPK), resulting in 12 treatment combinations of experimental units which were repeated 3 times. Based on the results of the study, there was no interaction between the effect of soil amendment treatment and the effect of inorganic compound fertilizers on the growth and yield of soybeans of the Anjasmoro variety (Glycine max L. Merril) on dry land.
