Abstract

Red chili (Capsicum annum L) is a kind of horticulture that has been high economic and nutrient value, so it’s impotent to increase the yield. With the modern technology in agriculture, many farmers have been planting without using soil such as aquaponics, especially for vegetables. This study aims to determine the most suitable planting media for the growth and yield of 3 red chili varieties. This research was used a factorial Randomized Complete Block Design (RCBD) with 3 replicates, which first factor was used 4 growing media (Cocopeat, husk charcoal, tankos and a combination of all) and the second factor was used 3 varieties of red chili (Kirana, pasemah and terano). Parameters measured; plant height, number of leaves, number of branches, number of fruits and weight of fruits. Tankos media and terano variety have a significant effect on plant height and leaf number, during the 4 weeks of observation. The number of branches and number of fruit, for both the treatments of the planting media and the varieties, were not significantly different, but the yield was significantly different as compared among them with terano was the better. It is clearly that, for high yield is terano variety, while the good medium is tankos. Of all the parameters observed, there was no interaction between media with varieties. Key words : Aquaponic, planting media, varieties, red chili

Abstract

WeRise is a rainfed specific technology (IRRI-JIRCAS-IAARD) that helps farmers to determine planting time according to rainfall distribution and specific variety. The research was conducted in West Nusa Tenggara (WNT) and Central Java at 2018, involving 15 farmers in each location. It compared planting time according to WeRise’s recommendation (1) and farmers’ practice (2), using the same variety, namely Inpari 41, which is a specific high yielding variety for rainfed. It was analyzed using the T test at the 5% level. The best WeRise’s recommendations in WNT was ± 1 December 2018, while farmers’ planting time was carried out on ± 15 November 2018. Meanwhile, in Central Java WeRise’s recommendations was same as the farmers, on ± 15 November 2018. However, testing was still carried out following the second / third alternative WeRise recommendation even though the yield prediction were lower (1 December 2018). The yield from WeRise treatment and farmer practices was not significantly different with an average yield of 5.01 t ha-1 for the WeRise treatment and 4.84 t ha-1 for farmer practice in Central Java and an average yield of 5.44 t ha-1 for the WeRise treatment and 5.65 t ha-1 for farmer practice in WNT. This means that in this initial validation WeRise had shown a fairly good performance with equivalent yield to farmers. However, it was suspected that Werise’s prediction in Central Java was still too low or 54% lower than the actual yield, while the prediction in NTB reaches 102%.

Abstract

Seed health is one of the important factors in maintaining seed quality. This factor is very influential both during seed storage, plant growth in the field, and production to be produced. Seed can be one of the effective media in the spread of plant diseases. With the consideration that pathogenic seed transmission plays an important role in the spread and development of epidemic diseases in some commodities, then gradually seed health tests need to be incorporated into the seed certification process. Seed health testing is required to detect the presence of pathogens or seed health status. To support the program of activities of the Ministry of Agriculture in the development of local rice, it is necessary to start by evaluating the health of seeds in the local paddy varieties. The purpose of the research includes detecting the type of pathogens carried by local varieties in several provinces and inventories of pathogen data carried by local varieties of rice seeds circulating in several provinces. The research method was conducted by taking samples directly from the field and conducting DNA isolation by PCR test to detect bacteria Xanthomonas oryzae pv oryzae (Xoo) and Burkholderia glumae (BG) as well as the growth of pathogen samples in the laboratory. The results of identification are known some seeds detected bacteria Xanthomonas oryzae pv. oryzae (Xoo) and Burkholderia glumae (BG)) which is characterized by the emergence of DNA bands PCR amplification results in positive control according to DNA Ladder. The results of the identification of pathogenic fungi, known the presence of fungi causing blast disease (Pyricularia oryzae) in the overall example of rice seeds tested (47 examples of local rice seeds upland and local swamp) and there are 15 examples or 32% infected with a percentage of infections 0.25 - 14.75%. While result identification of nematodes, known the presence of parasitic nematode Aphelenchoides besseyi on the overall sample of local rice seeds tested (42 examples of local rice seeds upland and local swamp), with 25 examples or 59.5% infected with an infection range of 1-44 specimens.

Abstract

Anthracnose is a disease that attacks papaya fruit while in the field and continues until the fruit is harvested and distributed to the market. Biofungiside made from citronella and green betel was expected to extend the selling papaya at inhibiting the growth of anthracnose. The study was aimed to determine the appropriate concentration of extracts of citronella leaves (Cymbopogon nardus L.) and green betel leaves (Piper betle L.) in inhibiting the growth of C. gloeosporioides as a cause of anthracnose. The extraction was done by boiling the leaves. The test methods used were in vitro and in vivo tests. In vitro tests were carried out to test the effectiveness of citronella leaf extract with concentrations of 5%, 10%, and 10%, 20% concentrations of green betel leaf extract in inhibiting the growth of C. gloeosporioides. The results of the in vitro test showed a significant difference (á = 0.5%) between treatments with the highest effectiveness value being 10% citronella extract with 47.22% growth inhibition of C. gloeosporioides and an average colony diameter of 3.150 cm after 15 days of incubation. The results of the in vivo test, showed significantly different results (á = 0.5%) between papaya fruit soaked with 10% citronella extract and controls, both in the incidence and spread of the disease. The spread of disease in treated papaya fruit was 13.72% while control papaya fruit reached 68.49% at 6 days of storage. Citronella extract with a concentration of 10% can extend the selling time of Calinna papaya (80% maturity index) 6 days longer than the control.
