Abstract

Increased production of reactive oxygen species or ROS is one of the common responses to a wide range of biotic and abiotic stresses. Increased production of ROS is outstripping endogenous antioxidant defense systems has been referred to as oxidative stress. Heavy metals are known to initiate ROS generation which is implicated as a oxidative stress. Cr is a toxic heavy metal that can generate ROS like H2O2 and O2 - which cause oxidative stress. In this study, chromium toxicity was studied to detect the oxidative stress on Sonchus oleraceus weed plants by the detection of superoxide anion and H2O2. Superoxide anion was detected by staining techniques with nitroblue tetrazolium (NBT) and hydrogen peroxide by Diaminobenzidine tetrahydrochloride (DAB) staining. Results indicated that the plants were grown in sand media generate the highest (0.89 A/g FW and 3.23 mol/g FW) than in soil media (0.23 A/g FW and 2.11 mol/g FW) superoxide anion (*O- 2) and H2O2 and soil containing textile sludge (0.18 A/g FW and 2.66 mol/g FW), respectively. At application of 10 mg Cr6+/L and 250 mg Cr3+/L, the production of *O- 2 and H2O2 in leaves of sonchus plants were significantly increased compared with the control plants. The highest production of H2O2 and *O- 2 were showed in the leaves of sonchus plants grown in sand media with Cr6+ application. In this study, either Cr3+ or Cr6+ caused oxidative stress in Sonchus oleraceus weed plants. The result also showed that sonchus plants esposed to toxic Cr can suffer from oxidative stress leading to reduction of its fresh and dry plants biomass. NBT and DAB in an appropriate probe and significant value for monitoring the formation of *O- 2 and H2O2 in plants.

Abstract

More than 80 high yielding varieties of rice have been released nationally by IAARD to support acceleration of national rice production. Inpari 13 was the one of some new variety that has been released at 2011 and have superior trait i.e early maturity and high yielding. Inpari 13 and some another new variety would disseminated at ICM program at this year. That variety needed to evaluated on Display Area and cultivated by using ICM technology and its compared with old variety as well as Ciherang. This study was to evaluate performance and yield of some new varieties compared old varieties specifically in Dem area. The experiment was conducted in West Java AIAT Dem Area, District Jayakerta, Karawang. The study was done on DS 2011 (Mei 2011-Januari 2012) by using randomized block design with 3 replications. Six varieties were tested i.e Ciherang, St. Bagendit, Inpari Inpari-7, Inpari-10, Silugunggo and Inpari-13. Integrated Crop Manajemen system i.e legowo 2:1, optimal fertilization, and IPM were used at this research. The results showed that there were signifant differences between varieties in all characters except leaf color index. Ciherang has the highest plant height (97,59 cm). Inpari-7 has the highest number of productive tillers and 100 grains weight (25 tillers/clump and 2,8 grams) and the least number of empty grains (7 grains/ panicle). St. Bagendit has the highest number of pithy grain (183 grains/panicle). Silugonggo was the early maturity but it’s resistant to stems brown planthopper (almost had a crop failure). The highest dry grain harvest was owned by Situ Bagendit (8,10 t.ha 1) followed Ciherang (8,08 t.ha-1), Inpari-13 (8,07 t.ha-1), Inpari-7 (7,52 t.ha-1), Inpari-10 (6,71 t.ha-1), and Silugonggo (2,05 t.ha-1).

Abstract

As agricultural waste, rice straw could be used to substitute potassium fertilizer in food crops farming system, especially rice crop. The use of rice straw in rainfed lowland areas is not significant to substitute potassium fertilizer which is relatively higher cost. The field experiment was conducted to determine potassium uptake pattern of rainfed lowland rice in light textural Endoaquepts through using straw and inorganic fertilizers. The experiment was arranged using split plot design where rice straw as main plot and potassium fertilizer as subplot. The variable observed was agronomic variable, potassium uptake, exchangeable potassium. The straw incorporation into soil increased the higher exchangeable potassium content in topsoil and also could reduce K losses due to leaching. The peak of K uptake was occurred at panicle initiation growth phase and gradually declined at reproductive growth phase. Interaction between rice straw and potassium fertilization increased significantly grain yield of 0.93 – 1.39 t/ha. The increase of potassium rate and its application method did not influence significantly grain yield of Ciherang variety.

Abstract

Annona squamosa L.is one of the perishable climateric fruit. The aims of this research were to study the ethylene levels, physiological and biochemical characters with application of temperatures and chitosan during storage. The research had been performed using Completely Randomized Design (CRD) with two factors, the variations in storage temperature (5°C, 15°C, 25°C) and the variation in chitosan (0%, 2%, 3%, 4%) with five replicates. The treatment of temperature 25°C and chitosan 0% was used as controls. The parameters observed included in respiration rate, weight loss, levels of ethylene, pigments, fruit hardness, ascorbic acid content and sugar reduction. Sugarapple fruit were taken from the same tree. The fruit were coated by chitosan and were stored at storage temperature. Observations were made in everyday until the controls were ripe. Data collected were analyzed using Anava followed byDMRTat 5% test level. The result showed that the combination of storage temperatures and chitosanconcentrationshadsignificant effect on the shelf life and quality of sugar apple fruit measured by several parameters. The treatments wereable to decrease weightloss and respiration rate, to maintain the content of water, the levels of sugar reduction, ascorbic acid content, the levels of a chlorophylls, b chlorophylls, total chlorophylls, and carotenoids were remained still high. The higher temperature is the lower the ethylene levels. The best combination treatment to extend the shelf life and to maintain quality of sugar apple fruit was chitosan 3% at temperatures 15°C.

Abstract

Indonesian society has a consumption pattern dominated staple grains group. To reduce dependence on other countries for imports of foodstuffs, need to diversification their meal using existing biodiversity. One of the crops that can be developed is the cocoyam (Xanthosoma spp.) potential as a source of carbohydrate. Cocoyam can be grown in the lowland to the mountains with a height of up to 1300 meters above sea level. Therefore it is necessary to find the most appropriate planting site so that plants can grow and develop optimally. This study aimed to determine the growth of three types of new cocoyam at a different altitude variation. This study was conducted in two different regions of altitude, is Tawangmangu (1200 m above sea level) and Klaten (98 m above sea level). Observations using three different types of cocoyam, the tuber white, purple and yellow. Each type grown in both altitude with 10 replications each. The observations were obtained include fresh weight, dry weight, number of leaves, chlorophyll and carotenoid levels were analyzed by unpaired t test and ANOVA test at 95% confidence level. The results of this study indicate that tuber white, purple and yellow tuber are planted in the lowlands (Klaten) and highlands (Tawangmangu) had significant results in the measurement of plant height, fresh weight, dry weight, and chlorophyll and carotenoid levels have significantly different results, but not the parameters of the number of leaves. Height and weight of the fresh plantin Klaten higher than in Tawangmangu, while the white tuber dry weight in Tawangmangu higher than other treatments. The levels of chlorophyll and carotenoid yellow tuber is the highest in Klaten than others.

Abstract

The research about portrait of local wisdom, climate change and the factors that affect the productivity of paddy was held on December 20, 2013 until March 21, 2014 in Kauman Kidul village, Sidorejo sub-district, Salatiga. The purposes of this study were 1) describing the portrait of local wisdom of farmers in Salatiga, 2) examining the effect of the seeds, fertilizers, pesticides, labors from the family members and outside family members, farming experience, local wisdom, climate change toward paddy’s productivity,and 3) examining the differences of paddy’s productivity and farmer’s income in 2009 and 2012. Samples were taken purposively, consist of 30 paddy’s farmer. Primary data were collected by survey method through interviewing by using structured questionnairesand secondary data collection is done by quoting monograph data and other documents related to the study. Data analysis using Cobb - Douglass production function with linear regression models were transformed into natural logarithm. The result of this study show that 1) there is local wisdom before planting and harvesting 2) partially, the fertilizers, pesticides, labors from outside the family members, local wisdom affect the paddy’s productivity, nevertheless the seeds, labors from family members, farming experience and climate change do not affect paddy’s productivity. Also 3) no prominent differences was found from the paddy’s productivity before and after the climate change, however there is prominent differences between the income before and during the climate change.
