Abstract

This study aims to determine the inhibitory ability of antagonistic fungi from the rhizosphere of pepper (Piper nigrum L.), betel nut (Piper bettle L.) and Bawang Suna (Allium cinense G.Don.) against Fusarium oxysporum capsici which causes damping off disease and its effectiveness as a seed coating against damping off disease in chili seedlings. The research was carried out in the laboratory and experimental garden of the Department of Agricultural Cultivation, Faculty of Agriculture, UPR. Testing the antagonistic inhibition of F.o.capsici in vitro, where the antagonistic fungus with the highest inhibition from each plant rhizosphere was used as a seed coating for chili seeds to determine its effectiveness in suppressing damping off disease on seedlings. The results of the study obtained nine antagonist fungi with very good inhibition against the pathogen F.o.capsici in vitro ranging from 70.36 – 77.74%. Three types of antagonistic fungi that are used as active ingredients in seed coatings are Gliocladium sp. from pepper rhizosphere (73.53% inhibition), Penicillium citrinum from betel rhizosphere (77.74% inhibition), and Trichoderma harzianum from suna onion rhizosphere (70.83%). The seed coating treatment with active ingredients from three types of biological agents significantly reduced the intensity of damping off disease (0%) compared to the control (23.75%). Control effectiveness reaches 100% with very good category. Seed coating with active ingredients of T. harzianum and Gliocladium sp was able to increase plant height by 34.06% and 43.11%, respectively, but there was no significant difference in increasing the number of leaves. Seed coating treatment with biological agents effectively protects seeds and plant seedlings from attack by pathogens F.o. capsici through mechanisms such as antibiosis, parasitism and competition, besides that rhizosphere fungi can induce plant resistance and produce growth regulators which can increase the growth of chili seedlings. It is hoped that in the future the seed coating treatment added with biological agents can replace the use of chemical pesticides in controlling soil-infected diseases

Abstract

Edamame soybeans are soybeans that are harvested young, so they are known as green soybeans. The high nutritional content and delicious taste make edamame soybeans popular with the public. Extensification is one effort that can be done to increase edamame soybean production. One type of soil that has the potential to expand edamame soybean plants is peat soil. This research aims to examine the response of edamame soybean plants to the application of dolomite and compound biofertilizer on peat soil. The experiment was carried out using a two-factor factorial Completely Randomized Design (CRD) with three replications.  The first factor, namely dolomite (0, 15, 30, and 45 g polybag-1) and the second factor, namely biological fertilizer (0, 5, 10, and 15 g kg-1 seed). The results of the study showed that the influence of the interaction between dolomite and compound biofertilizer as well as the single factor of compound biofertilizer had no significant effect on the growth and yield of edamame soybeans. Edamame soybean plants are responsive to dolomite. The highest number of plant seeds was obtained when administering dolomite at a dose of 30 or 45 g polybag-1, namely 29.50-32.25 seeds plant-1.

Abstract

The purpose of this study was to study the effect of dolomite and compound biofertilizer on changes in the chemical properties of peat and edamame plant yields on inland peat. Using a Factorial Completely Randomized Design with 2 factors. The first factor is dolomite lime with 4 levels, namely D0 = 0 t ha-1, D1 = 5 t ha-1, D2 = 10 t ha-1, D3 = 15 t ha-1 and the second factor is compound biofertilizer with 4 levels, namely H0 = 0 g.kg-1 seed, H1 = 5 g.kg-1 seed, H2 = 10 g.kg-1 seed, H3 = 15 g.kg-1 seed. The results of the study showed that increasing the dose of dolomite to 15 t ha-1 together with the provision of biofertilizer at a dose of 10 or 15 g.kg-1 of seed was able to provide the highest pH value, namely 4.06 - 4.18. In the parameter of peat total N value, only dolomite treatment gave a significant difference. The highest average Ca-dd value was obtained by addition 15 t ha-1 of dolomite together with biofertilizer  at a dose of 15 g.kg-1 of seed, which was 14.897 (gmol(+)/kg). The highest Mg-dd value was obtained by addition 15 t ha-1 of dolomite together with biofertilizer  at a dose of 15 g.kg-1 of seed, which was 36.680 (gmol(+)/kg). The highest number of pods (25.00 pods) and the highest pod weight (11.12 g) were obtained by addition 10 t ha-1 of dolomite. The highest number of pods occurred by biofertilizer at 15 g.kg-1 of seed (21.70 pods).
