Abstract

The productivity of chili in terms of both quality and quantity is suppressed by the attacks of anthracnose disease caused by Colletotrichum spp. Pesticides is commonly used to control the disease. Researched was conducted to determine the antagonistic fungi and the effective dose in inhibiting the growth of the Colletotrichum spp. Antagonistic tests were performed in vivo using the direct method with three replicates. Inhibition test was arranged in a Complete Randomized Block Design (RCBD) with 7 treatments: Control, Gliocladium sp (150, 250, and 350 mL/plant) and T. harzianum (150, 250, and 350 mL/plant) with four replicates and three samples out of 20 plants per treatment. The results showed that the percentage of inhibition of T. harzianum against Colletotrichum sp. is 55% while Gliocladium sp. is 70.33% in antagonistic test. The mean of disease intensity at 11 up to 32 DAI on control is 5.61 ± 0.71% up to 20.30 ± 1.35 % respectively. It is significantly higher than Gliocladium sp. 350 mL/Plant (1.94 ± 0.45 % up to 11.15 ± 0.87 %), T. harzianum 350 mL/Plant (1.10 ± 0.58 % up to 8.68 ± 0.91 %), and T. harzianum 250 mL/Plant (2.28 ± 0.43 % up to 8.75 ± 0.79 %). No significant different is observed on mean of fresh weight of red chili fruit yield per plant. T. harzianum and Gliocladium sp. fungi are effective in controlling the attack of anthracnose disease in chili. The most efficient dose to control anthracnose disease is the application of T. Harzianum or Gliocladium sp at the dose of 250 mL/plant.Key Words: Chilli, Anthracnose, Gliocladium, Trichoderma, Colletotrichum.

Abstract

The abundance of pests are influenced by soil fertility and plant density. Vigorous plants in narrow spacing led to pests infestation. Pests will have an effect on production of rice. Research was conducted in the village of Sentono, District of Karangdowo, Klaten regency, Central Java province, to identify the effect of various type of fertilization and “jajar legowo” planting system on the abundance of rice stem borrer in Diah Suci rice variety. Split plot design with two factors: variations in fertilization and jajar legowo planting system was used. The first factor (variations of fertilizer) as the main plot consisted of: inorganic fertilizer in recommendation dose (urea 100 kg/ha, Phonska 400 kg/ha, KCL 100 kg/ha), 50% inorganic fertilizer in recommendation dose + 10 ton/ha organic fertilizer products of BATAN, 50% inorganic fertilizer in recommendation dose + 10 ton/ha of organic fertilizer products of Faculty of Agriculture UPN “Veteran” Yogyakarta. The second factor was jajar legowo planting system as sub plot consisted of: 2:1, 3:1, 4:1. Observations on the abundance of rice stem borrer was carried out starting from 15 days after planting up to harvesting. The interaction between inorganic fertilization 50% + 10 tonnes of organic products of Faculty of Agriculture and jajar legowo planting system 3:1 and 4:1 was observed in terms of higher abundance of rice stem borrer and rice damage. Substitution using inorganic fertilizer in dose of 50% + 10 tonnes of organic products of BATAN were able to suppress the abundance of rice stem borer, however it was not influenced by type of jajar legowo planting system.Keywords: abundance, pests, fertilization, jajar legowo planting system

Abstract

Aims of, the research were to discover the influence the legin (legume) inoculation and the manure dosage to the growth and yield of the mug beans. The research was conducted at the research station at Wedomartani, District of Sleman, the Special Region of Yogyakarta. From June up to August 2018. Field experiment was arranged on the Randomized Complete Block Design with two factors, and repeated for three times. The first factor was legin application consisted of three levels, 9 g of legin/kg seeds, 12 g of legin/kg seeds, 15 g of legin/kg seeds. The second factor was cow manure dosage application consisted of five, dosage levels 0 ton/ha, 5 tons/ha, 10 tons/ha, 15 tons/ha, 20 tons/ha. The results of the research showed that the dosage of the manure had influence to the plant’s height and the leave’s chlorophyll. The best dosage of the manure is 10 tons/ha. The dosage of legin had influence on the plant’s height, leave’s chlorophyll, number of nodules, number of pods per plant, weight of sun dried seeds per plant, weight of sun dried seeds per plot, weight of 100 seeds and weight of sun dried seeds in ton/ha. The best dosage of the legin wais 15 g legin/kg seeds. The damage level of the plant did not influenced by the dosage of manure and legin. There was no interaction between the dosage of manure and legin in all observed parameters.Keyword: Mug beans, legin, cow manure.
