Abstract

A study was conducted to examine the effect of inoculum association between Rhizobium sp., mycorrhizae and Merapi-indigenous Rhizobacteria on the growth and yield of 3 soybean cultivars, and to determine the best inoculum and cultivars for soybean cultivation on coastal sandy soil. The study was conducted in the Agro-biotechnology and Research Laboratory and experimental station of Faculty of Agriculture, Universitas Muhammadiyah Yogyakarta during the period of September 2015 to June 2016. Experiments were conducted by using coastal sandy soil as planting medium in polybags by employing 4 x 3 factorial experiments, arranged in completely randomised design, and placed under the field condition. The first factor used was inoculation treatment consisted of 4 combination of inoculums: (1) Rhizobium sp. – mycorrhizae, (2) Rhizobium sp. – Merapi-indigenous Rhizobacteria, (3) Rhizobium sp. – mycorrhizae – Merapi-indigenous Rhizobacteria, and (4) without inoculation. The second factor was soybean cultivars consisted of 3 varieties: (1) Grobogan, (2) Detam-1, and (3) Petek. Observation was carried out on nodulation, mycorrhizal effect, Rhizobacterial population dynamics, plant growth and yield. The results showed that Rhizobium sp.–mycorrhizae inoculated on Petek increased root growth, leaf area and yield (5,97 tonnes/ha). Rhizobium sp.–mycorrhizae inoculation only increased diameter of nodules. It was also observed that the best soybean cultivar for coastal sandy soil was Petek.

Abstract

Sclerotium roflsii is the causal agent of damping-off disease on pepper which difficult to control. The use of chemical pesticides cause several damage to the environment. The used of Piper betle leaves extract which is contains antifungal compounds becomes one of the solution. The aim of this study to obtain the optimum concentration of piper betle leaves extract and dipping periode of chili seed in leaves extract to control damping off disease caused by Sclerotium rolfsii. The study consists of two experiments. The first experiment was isolation and multiplication of damping off disease in chilli, this stage was conducted in laboratorium. The second experiment was performed to investigate effectivity of piper betle leaf extract to control damping off using dipping method, this stage conducted in Greenhouse. The study arranged in Completely Randomized Design (CRD) with single factor experimental design consist of 13 treatment, namely consentration of 0%, 40%, 60% and 80% Piper betle leaves extract (v/v) with 1 hour, 2 hour, and 3 hour dipping time. The result showed that Piper betle leaves extract of 60% with 1 hour dipping time had the best ability among the other treatment to control damping off disease cause of Sclerotium rolfsii in chili seedlings.

Abstract

The experiment aimed to know the best inoculant and incubation time of organic fertilizer to the growth and yield of paddy. The experiment was conducted in Kasihan, Bantul, Yogyakarta. The altitude of experiment site is 110 m above sea level with the soil type of regosol.The experiment used the 3 x 4 factorial with one control and was arranged in Randomized Completely Block Design with three block as replication. The first factor was kind of inoculant to make organic fertilizer, consisted of 3 levels i.e (1) without inoculant, (2) EM4 and (3) Stardec. The second factor was incubation time, consisted of 4 levels i.e (1) 7 days, (2) 14 days, (3) 21 days and (4) 28 days. The control used organic fertilizer (Urea, SP36, KCl) with recommended dose.The result showed that neither organic fertilizer without inoculant nor with addition of EM4 and Stardec (with incubation time 7-28 days) affected significantly to the growth and yield of paddy, the used 3ton/hectare of organic fertilizer with or without inoculant did not affect significantly to the yield of paddy.

Abstract

Study on agronomic and economic performance characteristics of cassava (Manihot utillisima L.) in Gunungkidul Regency Special Region of Yogyakarta was conducted in April – August 2016. The research aimed to identify the agronomic and economic performance characteristics of cassava in Gunungkidul regency. Technical implementation of the survey method was conducted by observation and interview. The location of research sampling was determined by stratified random sampling method based on the category of district that has the most or broadest, medium, and small amount of cassava planting area. The respondents were chosen by purposive sampling method as much as 10% from the number of cassava farmers in a village or farmer group. The data were analyzed by descriptive and farming system analysis. The research result showed that there were some cassava cultivars observed, i.e. ‘Ketan’, ‘Pahit’, ‘Adira’, ‘Ireng’, ‘GatotKaca’, ‘Genjah’, ‘Mentega’, ‘Oyeng’, ‘Randu’, ‘Ambira’, ‘Klentheng’, ‘Srondol’, ‘PandesiHijau’, ‘Adira 1’, ‘Pandesi’, ‘Kirik’, ‘Gambyong’, ‘Jowo’, ‘Bamban’, ‘Kacibali’, ‘UJ-5’, ‘Marekan’, ‘Kresno’, ‘Meni’, ‘Merah’, ‘Malang’, ‘Kropak’ and ‘Aban’. Cultivation technology of cassava applied in Gunungkidul Regency is conventional technology. The maximum tillage system is applied in the soil tillage. Generally, Cassava is grown intercropping with rice, beans and maize. Manure is applied in cultivation technology and weeding is done six until ten times. There are eight types of pests attacking cassava plants. Cassava is harvested in seventh until tenth month after planting. Cassava farming is feasible in Gunungkidul Regency with R/C ratio (Revenue Cost Ratio) and B/C ratio (Benefit Cost Ratio) gained 1.

Abstract

The existence of weeds on sweet corn crops can lead to competition that reduce the yield. The aim of this research was to obtain the optimum crop proportion of corn-peanut plants in suppressing weed growth but not decrease the yield of sweet corn. The experiment was conducted using a single factor field experimental method arranged in a complete randomized block design with 3 blocks as replication. The treatment was the proportion of sweet corn-peanut population consisting of 3 levels, i.e 1:1, 1:2, 1:3, sweet corn monoculture and peanut monoculture as comparison.The results of this research showed that intercropping of sweet corn+peanut with  population proportion of 1:2 can suppress weed growth in on the 9th week (at harvest) without decreasing sweet corn yield.
