Abstract

Many problems arise in the cultivation of crops; one of these problems is insect pests that can threaten crop production. Integrated pest management is an alternative technique for managing the balance of the agricultural environment. Habitat manipulation by increasing plant diversity with refugia is considered an alternative way to maintain natural enemy in an agro ecosystem. The use of soybean as a refugium in a crop field is still limited. Research was conducted to investigate the diversity of predatory arthropods in soybean as a refugium in a chilli pepper crop field at the Agro-technology Training Centre (ATC) at the University of Sriwijaya. In this study, four varieties of soybean (Dena 1, Detam 3 PRIDA, Deja 1, and Devon 1) were used as refugia. Three observation methods were carried out using nets, pitfall traps and visual observation for 7 weeks. The results show that arthropod diversity in soybean plants comprised 6 orders with 10 families and 19 species. Odontoponera denticulata (Hymenoptera) was the most predominant arthropod predator, observed in 73% of all soybean varieties. The number of canopy-dwelling arthropod predators was similar in the four soybean varieties.

Abstract

Japan is the 3rd largest importer and consumer of coffee in the world. Considering have many demands of coffee, Japan is looking alternatives for improving to growing and the productivity of coffee. The research was aimed to assessment land suitability class for (arabica and robusta) coffee and land suitability evaluation of coffee. 3 soil samplings were collected from the study area. Matching method is used to evaluate the land suitability with parameter: temperature, elevation, rainfall, slope, pH, and nitrogen. The results showed that climate and physical condition of land area very suitable to grow robusta crops, and its level appropriateness is S1 (highly suitable). However, typhoon is problem in every year for growing coffee crops, but it can be handling by planting protecting crops.

Abstract

Dryland ecosystems have always been prone to relatively high vegetation and general environmental degradation; translating to changes in soil physical and chemical properties and massive carbon losses. Despite their vast surface area, Carbon sequestration therein still remains low. However, this low carbon means they are less saturated and therefore a tremendous potential therein to sequester more Carbon. Conservation agriculture with trees (CAWT) presents an opportunity to reduce the degradation and enhance the carbon stocks. This study was set to compare the biomass productivity and carbon sequestration potential of agroforestry between conventional and conservation agriculture practice. The study was carried out as part of ongoing experimentation established in short rain (SR) season of 2012 by the World Agroforestry Centre in a trial site at the Agricultural Training Centre (ATC) in Machakos county, Kenya. The trials adopted a split plot arranged in a randomized complete block design with two farming systems (conventional and conservation agriculture) as the main blocks, 7 treatments and three replicates, summing to a total of 42 plots. In the fields, two shrub species (Calliandra calothyrsus Meissn. and Gliricidia sepium Jacq.) were planted in three different spacing (1.5x1 m, 3x1 m, 4.5x1 m) for maize-legume intercrops. Trees were harvested by coppicing, weighed and leaf/twig samples taken for determination of biomass, which was then converted to Carbon using a conversion factor 0.5. The data was statistically analyzed using ANOVA and means separated using LSD at p <0.05. Results showed significant increase in carbon sequestration under conservation agriculture (p <0.001), with a yearly sequestration potential of between 12.8 and 24 Mg C/ha/yr compared to 11.6-23 Mg C/ha/yr for conventional practice. Calliandra also sequestered more carbon than Gliricidia. CAWT is therefore concluded to be a feasible way of increasing carbon stocks in the drylands.

Abstract

This research was conducted to investigate the effect of different herbicides with weed management practices on growth and yield performance of mungbean genotypes. The experiment consisted of two factors were mungbean genotypes and weed management. There were two genotypes namely BARI Mung 6 and BARI Mung 8. While there were five weed management practices namely control/no weeding and without herbicide application (T1), hand weeding at 20 and 40 DAS (T2), pre emergence herbicide (Panida) at 1-2 DAS (T3), pre emergence herbicide (Neon) at 2-3 DAS (T4), and post emergence herbicide (Neon) at 10-15 DAS+hand weeding (T5). The results revealed that BARI Mung 6 stand superior to BARI Mung 8 in respect of dry matter content/plant, pods/plant, seeds/plant, seed yield, and 1000 seed weight. Among weed management practices, maximum plant height (53.70 cm), dry matter weight/plant (17.96 g), pods/plant (18.31), seeds/plant (171.47), maximum weed control efficiency (33.78 %) obtained from T3 treatment. Based on the interaction effect showed that BARI Mung 6 weeded with pre emergence herbicide (Panida) at 1-2 DAS produced maximum seed yield (1.79 t/ha) as well as yield attributes showed 2.29 % higher seed yield.

Abstract

The peel of red dragon fruit usually discarded. It is rich in polyphenol compounds that have antioxidant activity and health benefits. This research aimed to determine the antioxidant properties of herbal tea such as phenolic content, betacyanin content, and antioxidant activity. The herbal tea prepared with hot oven drying methods, where’s the fresh peel of red dragon fruit and ginger were cut to be small pieces and dried at 60oC, and ground into tea powder then mixed as treatments. Results showed that the addition of ginger has no significant effect on phenolic content, and betacyanin content decreased by the addition of ginger. The phenolic content of herbal tea (0% ginger) and the highest addition of ginger (12%) were 3.39±1.19 mg GAE/g and 3.59±1.43 mg GAE/g respectively. The betacyanin content were 124.63±1.61 mg/100 g (0% ginger) and 104.01±2.99 mg/100g (12% ginger). As the amount of ginger added increased, the percentage of inhibition of herbal tea decreased from 66.23%±2.67 to 61.19%±2.45%.
