Abstract

Research on the effect of dosage combination of Evagrow bio-fertilizer and chemical fertilizers on soil properties, growth and yield of rice has been carried out in the glasshouse, Faculty of Agriculture, Udayana University using factorial experiment with a Randomized Block Design (RBD). The first factor is Evagrow bio-fertilizer in 3 level, i.e. E0 (without bio-fertilizers), E1 (5 g bio-fertilizer/L) E2 (10 grams bio-fertilizer/L). The second factor is chemical fertilizer, which consists of 3 levels: K0 (without chemical fertilizers), K1 (150 kg Urea/ha + 75 kg SP36/ha + 37.5 kg KCl/ha), K2 (300 kg Urea/ha + 150 kg SP36/ha + 75 kg KCl/ha). The results showed that chemical fertilizers give a significant and very significant effect on most of the rice growth and yield parameters. The application of chemical fertilizers K1 and K2 increased yield of dry grain harvest to 52.87% and 102.54% compared to controls. ?Application of Evagrow bio-fertilizer did not significantly increase growth and yield of rice. There is no interaction between chemical fertilizers and Evagrow bio- fertilizer. ?Similarly to some of the soil characteristics, biological fertilizer and chemical fertilizer application did not show significant effect on most of the soil characteristics, except on salt levels.Keywords: Evagrow Biofertilizer, Inorganic Fertilizer, Oryza Sativa

Abstract

Green grass jelly (Cyclea barbata Miers.) is known for its benefit to human health especially in supporting body?s immune system and wellness. This research aimed to determine immunomodulatory and antioxidant activity of green grass jelly leaf extracts in vitro. Old leaves were collected as sample then dried and ground to powder. The extraction was done with sohxletation using three different solvents, chloroform, ethyl acetate, and ethanol. The immunomodulatory activity was evaluated by treating the crude extracts at concentrations of 50, 100, and 500 mg/mL on macrophages of rat in vitro. The treated macrophage was then challenged for their phagocytic activity to latex beads. The antioxidant activity was done using 1,1-diphenil-2-picrilhydrazil (DPPH) with spectrophotometry technique. All treatments were done with three replicates. Detection of the bioactive groups of the extracts was done by Thin Layer Chromatography (TLC). The results showed that ethyl acetate extract has the highest phagocytic activity followed with chloroform extract and ethanol extract, respectively. Optimum concentration was reached at 100 mg/mL of ethyl acetat extract. The ethyl acetate extract was also the extract with the highest antioxidant activity index 7.7 followed by both extracts of chloroform and ethanol with similar index value of 6.25 and 6.3, respectively. The ethyl acetate extract contained phenolics, flavonoids, tannins, and terpenoids.

Abstract

The incidence of diseases caused by pathogenic viruses in chili is still a major problem in reducing the production of chili in Indonesia. Most agricultural crops are hosts for one or more types of plant viruses, so the viru s continued to be a problem in the tropics. Virus is passive, requires intermediaries vector to be transmitted to other plants. The goal of this research was to develop control strategies for aphids that act as a viral vector and pest chili plants using plastic mulch. Control design that was developed in this study based on the habits of local farmers, using plastic mulch with two colors, black and silver. Mulching is done to dispel the arrival aphids into the chili crop, at the same time preventing the emergence of weeds that act as alternative hosts of the virus. The use of silver plastic mulch to control vector viral populations was better compared to black plastic mulch during ?chili planting. The use of silver plastic mulch can improve yields of chili crops.Keywords: Aphid, whiteflies, Chili chili, virus

Abstract

For cattle, red calliandra (Calliandra calothyrsus) is a good protein source of forage but the condensed tannin content is the highest compared to other legume plants. Tannin can reduce the activity of digestive enzymes and protein digestibility, which can lead to pancreatic hypertrophy and hyperplasia. This study aimed to determine the pancreatic histology of pregnant rats treated with C.calothyrsus leaf flour during pregnancy and lactation period. This study used a completely randomized design with 24 pregnant female rats which were divided into four groups i.e. control and treatments of 10, 17.5 and 25% of C.calothyrsus leaf flour in the diets. The treatment started from the first day of pregnancy until the young rats were weaned at the age of 21 days. Pancreatic histological structure of the mother showed an increase lack of normal tissue density and an increase connective tissues in the pancreas descriptively, especially at the highest level of C.calothyrsus leaf flour (25%) in the diets.

Abstract

Cocoa pod disease caused by the fungus Phytophthora palmivora has resulted in loss of cacao in Indonesia, especially in Bali. So far the disease control strategy is not fully understood. So there is a need to find an alternative by using endophytic fungi associated with cocoa plant. Endophytic fungi are needed to be explored in all parts of the cocoa plant such as stems, leaves and husks. The prevalence of fungal endophyte was determined by the size of its domination on the surface tissue for protection against pathogen. The exploration of the endophytic fungi benefits is aimed at finding biological agent s that could control of pathogenic P. palmivora. ?The results showed that 15 types of endophyte fungi have been found in the healthy leaves, stem and pod husks, with the prevalence of fungal endophyte originated from healthy leaf Mecelia sterilia (hyphae sterile) around 30%, the endophyte fungi originated from the healthy cocoa stem are Mycelia sterilia, Neurospora spp and Trichoderma spp around 25%. While the endophytic fungi originated from healthy skin fruit is Trichoderma spp. around 35%. The in vitro test results of endophytic fungi antagonistic against P. palmivora indicated that the endophyte fungi originated from the leaf namely Aspergillus spp was obtained at 80 ? 2%, A. niger 90 ? 2%, A. flavus 100%, and Trichoderma spp. 90 ? 1.5%, the endophytic fungus originated from rods namely Neurospora spp. was 95 ? 2%, and Trichoderma spp. was 90 ? 2%. While the endophytic originated from rind namely Neurospora spp . was 95 ? 1.5 % and Trichoderma spp. was 80 ? 2%. The results of in vivo test of antagonistic endophytic fungi against P. palmivora showed that all of endophytic fungi (Aspergillus sp., A. niger, A. flavus, Neurospora sp., and Trichoderma sp.) have a significant effect in suppressing the growth of mycelium P. palmivora.Keywords: Endophytic Fungus, Phytophthora Palmivora, Inhibition, Prevalence, Biological Agents
