Abstract

The aim of this research was to examine the diversity of indigenous plant growth promoting rhizobacteria from paddy soil and to obtain a superior isolate that can support the growth and vigor of rice plants. This research was conducted in the Laboratory of Agronomy and Horticulture, Faculty of Agriculture, Jenderal Soedirman University from July to September 2017. The bacteria were isolated from paddy soil rhizosphere originated from rice production centers of Banyumas Regency i.e. Kebasen, Rawalo, Patikraja, Jatilawang, and Karangwangkal. Results showed that indigenous PGPR from paddy soil were able to produce Indol Acetic Acid (IAA) in the range 0.05-5.40 ppm, but did not have the ability to solubilize phosphate. Plant Growth Promoting Rhizobacteria (PGPR) inoculation in rice seedlings was able to increase seed vigor, plant height, root length, and seed germination. Based on morphological and biochemical characters, PGPR isolates were identified as Bacillus sp., Pseudomonas sp., Streptococcus sp., and Staphylococcus sp.

Abstract

To reduced losses in rice farming requires the application of modern agricultural machinery in harvesting equipment, postharvest and processing. Varying knowledge of farmers and entrepreneur rice milling unit (RMU) in yield loss as well as the impacts of global climate change research should be conducted through a structured survey of farmers and entrepreneurs RMU in Yogyakarta. Results obtained demonstrate the preferred use of new type variety among farmers so that the tool is suitable harvest sickle cutting down system in districts of Bantul and Gunungkidul more popular as straw used for animal feed. More than 70% of farmers do at harvest time by looking at the panicle and leaf color. Utilization of power threshers more developed in Sleman because of such preferred cut up and threshing by stampede way. With the limitations of manpower, the farmer was forced to delay harvest in Gunungkidul. The thickness of the grain is dried in the sun need to be added so as not too thin and can produce more rice intact during milling. Entrepreneur RMU need to complete with seed cleaner to increase the yield, as well as using double-pass system so that quality and yield of rice produced would be better.

Abstract

Rot fungi are microorganisms that can degrade biomass, especially biomass containing carbon. This fungus can decompose wood components (lignocelluloses) into simpler compounds. This research aimed to determine the diversity of rot fungi that have fruit body and grow in cocoa plantation as well as to observe their morphology and ability to grow on carbon source media. Fruiting body was taken from decayed cocoa stems from the farmers’ cocoa plantation in Bila Village, Pitu Riase, Sidrap Regency, South Sulawesi. The fruiting body then was sterilized and grown on the PDA medium.. The isolates then were morphologically characterized and grown on a solid Czapek dox medium containing carbon source of lignin, chitin, cellulose, and pectin. The rot fungi from Basidiomycota found were Mycena spp, Lycoperdon spp, Auricularia spp, Schizophyllum spp, Coprinus spp, Tremella spp, Crepidopus spp, Trametes spp, and Pleurotus spp. The different growth abilities were characterized by the large diameter of the colony formed. The highest colony diameter of Lycoperdon spp was on cellulose media, while that of Tremella spp was on the three other media. The results show that the rot fungi from cocoa plant have a large potential to be used as biodecomposer.

Abstract

Problems crop cultivation on rain fed land after rice is still too wet for crops, while for rice crop will experience drought on the generative phase. The technology was required to decrease the moisture content of the soil so that crops can be planted after rice. The study aims to examine the application of the use of the underground drainage system to lower the water logging. Local raw materials were used in order to easily adopted by farmers, because common uses of the pipe is still too expensive. The drainage material was made of a collection of coconut husk and wood twigs. As a test medium performed using texture medium sandy clay loam soil and sand. The test results showed that the ability of the drainage flow on coconut fiber, lower than that of wood sticks consecutive 0.37 and 0.48 liters / sec. And the maximum flow capability was shown in the sandy soil of 0.75 and 1.93 liters / sec. Condition of the land with drainage modulus 10mm / day and the structure of materials was used in the field of wood sticks with inter-channel spacing is 10 m, then there is a 10 in 1 ha pipeline, so the ability to discharge to 69 m3 / h. Therefore, it took time for water discharge at 100/69 = 1.45 This means that the potential of using systematically drainage disposal is fit for use primarily in the light texture such as sandy clay loam.

Abstract

Rice production can be improved through extensification using sub-optimal lands. One type of land that can be used for extensification of rice production in D.I. Yogyakarta is eucalyptus agroforestry system in Playen, Gunung Kidul. Besides expanding the land use, it can also increase farmers’ income and ecological functions. However, this system has limiting factors such as the limited availability of water, which only relies on rain. Thus, proper water management and fertilization are necessary to fulfill water and nutrient requirements for rice growth. This study aimed to determine the effects of the application of trenches with organic matter and the doses of KCl on the growth and yield of upland rice (Situ Patenggang) in eucalyptus agroforestry systems. The study was conducted at the Menggoran Forest Management Resort, Bleberan, Playen, Gunung Kidul in March-August 2018. The study was arranged in a split-plot design with three blocks as replications. The first factor was the application of trenches with organic matter, while the second factor was KCl fertilizer at. various doses. The data obtained were analyzed using analysis of variance (ANOVA) at the level of 5%. The optimal dose of KCl fertilizer was determined by regression. The results showed that both factors had a positive effect on soil moisture content, growth, physiology, and yields of upland rice. The treatments significantly increased the availability of water in the soil, thereby supporting the growth and yield of upland rice.

Abstract

Identification of fruit flies of dragon fruit in Tanah Laut has never been conducted. This research was aimed to identify fruit flies species of dragon fruit and its natural enemies in Batu Ampar, Tanah Laut, Kalimantan Selatan. The fruit flies attacking dragon fruit in the field was collected. Observation was performed on the development of the larvae until adult and finally emerging adult was identified as well as its parasitoid. The result showed that the obtained fruit flies was Bactrocera dorsalis Hendel and Aceratoneuro myiaindica (Hymenoptera: Eulophidae: Tetrastichinae) was found as the parasitoid. Five predators was found as its natural enemies, namely red ants (Hymenoptera: Formicidae: Solenopsis), rangrang ant (Hymenoptera: Formicidae: Oecophylla), spiders (Arachnida), kumbang stafilinid (Coleoptera: Staphylinidae: Paederinae) and earwig (Dermaptera: Forficulidae: Forficula).

Abstract

The research was conducted to study the effect of palm sugar waste compost using cow rumen activator on sweet corn cultivation and to determine the effective concentration of cow rumen activator and dose of sugar palm waste compost for sweet corn cultivation in coastal sandy soil of Samas Beach, Bantul. The research was arranged in Completely Randomized Design (CRD). A total of 11 treatments consisting of combination between the dose of sugar palm waste compost (tonnes/hectare) and various concentrations of cow rumen activators (%), with detail as follows: (1) 20 tonnes/hectare and 60%, (2) 20 tonnes/hectare and 70%, (3) 20 tonnes /hectare and 80%, (4) 20 tonnes/hectare and 90%, (5) 20 tonnes /hectare and 100%, (6) 25 tonnes/hectare and 60%, (7) 25 tonnes/hectare and 70%, (8) 25 tonnes/hectare and 80%, (9) 25 tonnes/hectare and 90%, (10) 25 tonnes/hectare and 100%,  and (11) 20 tonnes/hectare of inorganic fertilizer. Each treatment was replicated four times. The results showed that the treatments of sugar palm waste compost with various concentrations of cow rumen activator and commercial compost had no significant effect on almost all plant parameters, except the root fresh weight. In addition, sugar palm waste compost with various concentration of cow rumen activator produced higher fresh weight of ear with husk compared to the potential yield of Sweet Boy variety. Dose of 20 tonnes/hectare of sugar palm waste compost with cow rumen activator at a concentration of 60% is the most effective treatment for sweet corn cultivation in coastal sandy soil of Samas Beach, Bantul.
