Abstract

Potato (Solanum tuberosum) is a seasonal shrub-tuber crop originated from sub-tropical area. Soft-rot is one of the most important diseases of potato. It can be caused by Pectobactorium atrosepticum, a pathogen within a status of quarantine plant pest A1 type I in Indonesia. The objective of this study was to know the incidence of potato soft rot disease and to detect P. atrosepticum in major potato-growing areas in Central Java Province by applying the serology method using DAS-ELISA technique. Survey of soft rot disease was carried out in some regencies in Central Java Province, i.e. Magelang, Banjarnegara, Wonosobo and Karanganyar. The field survey of potato plant in all the regencies indicated symptoms of stem rot which was black in color (blackleg) and foul-smelling, with disease incidence of about 10–90%. The laboratory testing showed that by applying DAS-ELISA method, P. atrosepticum was detected in samples collected from Pandean and Bagongan villages, district of Ngablak,Regency of Magelang, Central Java Province.

Abstract

The experiment aimed to determine the effect of different environment (altitude and drought stress) on the growth, yield per plants, capsaisin levels, and peroxidase activities of four chili cultivars. Capsicum annuum (‘Lado’ and ‘Gada’) and Capsicum frutescens (‘Pelita’ and ‘Sona’) were grown with standard cultivation in medium land (± 700 m asl, Kaliurang) and low land (112 m asl, Bulaksumur) in two environments i.e. standard cultivation and drought treatment. The cultivars were arranged in Complete Randomize Design with four replications in each environment. The data were analyzed using analysis of variance with orthogonal contrast model, while the GGE biplot was applied for identification of stability. The result showed significant interaction between environment and cultivar on plant height, fruit’s weight per plant and the contents of capsaicin. Medium land of Kaliurang had suitable environment for chili cultivation of four cultivars and the high capsaicin content of C. frutescens. ‘Gada’ was significantly higher than other cultivars for fruit weight per plant in all planting conditions, while ‘Sona’ had the highest capsaicin content and was stable in all environments. Drought stress increased capsaicin content in low capsaicin content variety, in contrast to high capsaicin content cultivar. Peroxidase enzyme activity of C. frutescens was significantly higher than C. annuum, while C. annuum cultivars also shown significantly different in peroxidase activity.

Abstract

The objectives of this research were to understand farmers’ perception to risk and risk management strategy on shallot farming. The research was conducted in Bantul and Nganjuk Regency. The number of samples taken were 57 farmers in Bantul and 90 farmers in Nganjuk. Analysis used was frequency table that disaggregate based on agroecosystem and cropping pattern. The result showed that according to farmers’ perception, production and price risk were high. Farmer's decision to follow dominant cropping pattern and production system reflected on the ex ante risk management strategies done by the farmers as their own respection. In the interactive risk management strategies, farmers tended to use chemical fertilizers over chemical pesticides. In ex post risk management strategy, in the failure of shallot farming, they kept cultivating shallot that their capital got on cash and input for shallot farming.

Abstract

Sandy coastal area is a poor land, with minimal nutrients and low ability to store water and nutrition. Therefore, plant is difficult to grow well, consequently the treatments for improving sandy coastal is required before planting to support their growth. Application of Trichoderma as a plant-growth promoting and controlling pathogens had been known. Shallot seed treatment by Trichoderma agents was intended to improve and support plant growth and yield in the sandy coastal land. The aim of experiment was to determine the most effective treatment to improve growth and yield of shallot on sandy coastal land. The experiment had been carried out in Yogyakarta during August - November 2015. The factorial treatments of cultivar and Trichoderma applications were arranged in Completely Randomized Design with three replications. The shallot cultivars consisted of Tiron, Crok, and Biru, while Trichoderma application consisted of control (no treatment), sprayed with Trichoderma, soaked in Trichoderma, matricontioning media i.e. rice husk charcoal and brick in combination with Trichoderma. The collected data related to plant growth and yield. The result showed that seed treatment methods with Trichoderma increased the plant height, the leaf area index, extensive root, net assimilation rate (NAR), plant growth rate (PGR), Nitrate Reductase Activities (NRA), total chlorophyll, and fresh bulb weight. The best technical treatment for cultivar Tiron was soaked with Trichoderma, and Crok was sprayed with Trichoderma, while Biru cultivar was using brick in combination with Trichoderma.

Abstract

Fusarium wilt caused by Fusarium oxysporum f.sp.cepae (Foc) is one of the most important diseases of onion in Indonesia. Induced resistance was one of the effective techniques to acquire resistance to fusarium wilt in shallot. Salicylic acid (SA) had been inferred to be in endogenous signal in the systemic acquired resistance response of plants. This research aimed to study the effect of exogenously added SA to resistance in shallot callus cv ‘Bima Brebes’ to fusarium wilt disease in vitro; and to determine the effective concentration of SA to induce resistance. A group of shallot callus was grown in MS medium containing varying SA concentration (0, 15, 20 and 25 ppm) in vitro for 2 weeks. Then, the callus were treated with toxin of Fusarium oxysporum, namely fusaric acid, to have observe the resistance response. In vitro selection was done twice in different fusaric acid concentration. Application of exogenous SA at all concentration did not suppres time of appearance of disease symptom yet. Toxic symptom in the callus was shown by the browning or blackening (off) of callus. Salicylic acid at concentration of 20 ppm effectively reduced the toxic symptom up to 16.66% and supported callus regeneration better than the concentration of 15 ppm and 25 ppm. The number of resistant callus regenerated was 66.67% at pretreatment of 20 ppm of SA.

Abstract

Curly red chili was one of vegetable commodities in Indonesia used for seasoning of home cuisine, food industry, and pharmaceutical industry. Curly red chili cultivation needed fungicide to prevent fungal disease. Pyraclostrobin was a fungicide which could overcome fungal attack and improve plant growth. This research was conducted to study the effectiveness of pyraclostrobin application on vegetative growth of curly red chili plant. Research had been done in farmer’s land in Kemiriombo Village, Dukun Sub District, Muntilan District, Magelang Regency from December 2013 to June 2014. The treatments were assigned in the Randomized Complete Block Design with three replications. The treatments consisted of P1: pyraclostrobin doses 1.5 kg ha-1, 30 and 90 days after planting (dap), P2: pyraclostrobin 1.5 kg ha-1 at 30, 60, and 90 dap, P3: pyraclostrobin 1.5 kg ha-1, at 15, 30, 60, and 90 dap, P4: pyraclostrobin 3 kg ha-1, at 30 and 90 dap, P5: pyraclostrobin 3 kg ha-1, at 30, 60, and 90 dap, P6: pyraclostrobin 3 kg ha-1, at 15, 30, 60, and 90 dap, and P0: control (no treatment). Data were analyzed by orthogonal contrast test with α=5%. The result indicated significant different in the dry weights of root, stem, leaf, and total yield at 12 weeks after planting; number of flower at 9-11 week after planting, 14 week after planting, and 18-21 week after planting; and number of fruits at 10-12 week after planting, 15, and 16 week after planting. The application of pyraclostrobin at all dosages could increase IAA content. The numbers of flower and fruit were influenced by the increasing of IAA content in plant tissue, but did not affect the yield.

Abstract

The marginal sandy coastal land should be utilized to maintain production level of shallot. But for increasing the productivity of sandy coastal land, in the shallot cultivation should be applied biological fertilizers, such as Plant Growth Promoting Rhizobacteria (PGPR). The purpose of this research was to obtain the most effective isolate of PGPR (Plant Growth Promoting Rhizobacteria) to the growth of three shallot cultivars in the sandy coastal land. The research had been conducted in August-November 2015 at Samas sandy coastal land, Bantul. The Factorial treatments were assigned in Randomized Complete Block Design with three blocks as replications. The first factor was shallot cultivars consisted of Crok, Tiron and Tuk-tuk, while the second factor was the PGPR suspension, i.e. control (without PGPR), PGPR isolates BP25.2 (Bacillus methylotrophicus), BP25.6 (Bacillus amyloliquofaciens), BP25.7 (Bacillus subtilis), BrSM 4 (Burkholderiacepacia), and BrSG 5 (Burkholderiaseminalis). The data of growth and yield were analyzed using ANOVA with α = 5%, then followed by DMRT α 5% . The result showed that Tiron cultivar was able to grow in sandy coastal land, proven from its good germination, high number of bulb, high fresh weight, and dry weight of bulb. Meanwhile, BP25.2 isolate was able to increase seed growth simultaneously of Tiron cultivar and BrSM 4 isolate was able to increase the chlorophyll content of Tuk-tuk cultivars.

Abstract

In protecting and empowering the farmers, farmers group, and farmers group association (Gapoktan) from falling prices of grain and rice at harvest time and food accessibility problems, the government through the Ministry of Agriculture and Food Security Agency implemented the Strengthening the Institutions of Community Food Distribution Program (Strengthening-LDPM). This research was aimed to analyse the level of efficiency and to identify factors influencing the efficiency of Gapoktan in implementing the Strengthening-LDPM by involving 40 Gapoktan post-independence. The data used in this research were primary and secondary data, drawn from stockopname reports in 2014. This research used DEA (Data Envelopment Analysis) analysis, assuming that CRS (Constant Return to Scale) and VRS (Variable Return to Scale) using output-oriented assumptions. In addition, factors affecting the efficiency were analysed using multiple regression OLS (Ordinary Least Square). Based on DEA-CRS approach, as much as 37.5% Gapoktan were efficient and 62.5% Gapoktan were inefficient. Whereas with the approach of the DEA-VRS, 50% Gapoktan were efficient and 50% Gapoktan were inefficient. The average age of Gapoktan board, total volume of grain or rice sales, total volume of food reserve, and total loan interest affect significantly in increasing the efficiency of Gapoktan in running the strengthening-LDPM Program.

Abstract

Biological diversity index could be used as an option to assess the stability of an agricultural ecosystem. This limited field research was aimed to determine the effect of vermicompost and flowering plants (Asteraceae) to the diversity of herbivore and carnivore arthropods (M+). Conventional treatment with the application of non-organic fertiliser and without the addition of flowering plant was used as control (M0). Sampling was conducted using insect nets, and began at 30 days after planting (DAT), and repeated every other week until before harvesting. The results showed that the diversity of herbivore and carnivore arthropods in modified plots with organic fertiliser worm cast and flower plants/habitat manipulated system (M+) was moderate (herbivores: Shannon diversity index from 1.1 - 2.2; carnivores: 1.93 - 2.09), as well as the diversity of arthropods in the field of non-modified/custom system (M0) (herbivores: Shanon index of 1.2 - 1.7; carnivore: 1.34 - 2.18). Meanwhile, the number of arthropod species found in the M+ plot was 59 species, consisted of 22 herbivores and 37 carnivores (9 order, 32 families, and 35 genera). Number of arthropods found in the M0 plot was 54 species, consisted of 17 species of herbivores and 37 species of carnivores (7 orders, 28 families, and 30 generas). Statistical analysis showed that there was no significant difference in the plot diversity M+ and M0. Nevertheless, mean diversity of the M+ plot tended to be higher (Shannon Index herbivore and carnivore = 1.6 = 2.01) compared with M0 plot (herbivore and carnivore = 1.45 = 1.76).
