Abstract

[GROWTH AND YIELD OF FOUR VARIETIES OF MUNG BEAN (Vigna radiata L.) PLANT ON DOSING OF CHICKEN MANURE FERTILIZER IN ULTISOL]. Ultisols generally have less favorable physical, chemical, and biological properties. Chicken manure is believed to be able to improve soil structure, increase water holding capacity, increase soil pH, increase cation exchange capacity, increase soil biological activity, and facilitate root penetration. This study aims to determine the optimum dose of chicken manure in increasing the growth and yield of four mung bean varieties in Ultisol. This research was conducted using a split-plot design. The doses of chicken manure (0 tons/ha, 10 tons/ha, 20 tons/ha, and 30 tons/ha) were placed in the main plots and mung bean varieties (Vima-1, Vima-2, Kutilang, and Murai) as children. plots with experimental plot units measuring 1 m x 2 m. This study aims to obtain the optimum dose of chicken manure on four varieties of mung bean plants and to find the varieties that have the best growth and yield of green bean plants in Ultisol. The results showed that the highest weight of 100 seeds was obtained from the Kutilang variety which was given chicken manure of 21.34 tons/ha with a maximum weight of 100 seeds of 8.82 g. The highest yield of seed/plant weight was obtained from the application of chicken manure 19.61 tons/ha with a yield of 15.43 g. Kutilang variety is the best variety compared to other varieties, with yields of seed weight/plant of 12 g.

Abstract

[THE INFLUENCE OF BOTANICAL INSECTICIDES BASED ON CROTON OIL AND DERRIS ROOT AGAINST BROWN PLANTHOPPER]. Brown planthopper (BPH) (Nilaparvata lugens Stall) is a serious pest in rice. Using synthetic insecticide to control BPH is harmful for human health and can caused environmental pollution. The objective of this research is to find out ecofriendly insecticide to control BPH. Research has been conducted at Entomological laboratory, Indonesian Spice and Medicinal Crops Research Institute (ISMECRI), Bogor. It was designed with CRD, 16 treatments and 3 replications. Treatments consisted of botanical insecticides based on Croton tiglium and Derris elliptica. Each material was extracted by water, methanol, and xylene, and then tested by individually and combination, so there were 15 formulas and 1 control treatment (water). Third nymph BPH and IR64 rice variety were used in this research. Research was done in two methods, i.e. contact application and residual application. The result shows that there are 11 formulas which are prospective to be further developed i.e aqueous extraction (6 formulas) and combination extraction (aqueous with xylene and methanol (5 formulas). The aqueous extraction maybe the most prospective formulation since the technique could easily be adopted by farmers. Botanical pesticide based on Croton tiglium and Derris elliptica are very promising, therefore the research should be continued to find out the best formula of botanical insecticides for controlling BPH).

Abstract

[DIVERSITY AND THE SOURCE OF RESISTANCE GENE OF LOCAL RICE VARIETIES ON THE PATHOGENIC OF Pyricularia grisea CAUSE OF BLAST DISEASE]. Local rice varieties are known to have resistance or source of genes to  pests even though their productivity yield is low. The pathogen of Pyricularia grisea is a cause of blast disease, which is one of the obstacles in rice production. The research aims to characterize the resistance of local rice varieties to the  pathogen of P. grisea and to evaluate the virulence level of P. grisea pathogens against local rice varieties. A total of 100 local rice varieties and check varieties are susceptible and resistant namely Kencana Bali and Situ Patenggang tested their resistance to 4 dominant pathogenic of P. grisea i.e. races 033, 073, 133 and 173. Inoculation was carried out on stages 4-5 leaves or 18-21 days after seedling in a green house. The results showed a high genetic diversity of local rice varieties against pathogenic races 033, 073, 133 and 173. Based on the response of local rice varieties resistance i.e. moderately resistant (MR), resistant (R) and susceptible (S) to pathogenic races 033, 073 , 133 and 173 obtained 45 resistance response patterns. Cere Bereum varieties which are local rice varieties from West Java and Situ Patenggang resistant check varieties have a resistant response to 4 P. grisea pathogenic races used. A number of local rice varieties also show a resistant and moderately resistant response to the four pathogenic races used include Siam 11, Pare Siriendah, Menyan, Cere Manggu and Enud-Rawa Bogo. Local rice varieties Djedah and Padi Hitam (2) are local rice varieties that have a specific response of resistant or moderately resistant to race 173.  Race 133 and 173 have higher virulence rates than those of races 033 and 073 on local rice varieties. The results of this study indicate that there is a great potential for the utilization of local rice varieties, as a source of resistance genes for blast disease for the assembly of rice varieties that are resistant to blast disease.

Abstract

[GROWTH AND YIELD OF FOUR VARIETIES OF MUNG BEAN (Vigna radiata L.) IN INTERCROPPING SYSTEM WITH VARIOUS CORN PLANT SPACING]. Efforts to increase the productivity of mung beans (Vigna radiata L.) can be done by implementing an intercropping system and using superior varieties. Corn plants need high nitrogen and mung bean plants can fix nitrogen from the free air so that corn plants can take advantage of the excess nitrogen from mung beans. The purpose of this study was to determine the best mung bean varieties in the intercropping system with a various spacing of maize. The research was conducted in October-December 2018, in Pematang Gubernur village, Muara Bangkahulu, Bengkulu. The experiment in this study used a split-plot design with the main plot spacing of maize that was 60 cm x 30 cm, 90 cm x 30 cm, 120 cm x 30 cm, subplots were mung bean varieties (Vima-1, Vima- 2, Vima-3, and Kutilang) with 3 repetitions. Repeated 3 times, then 36 experimental units were obtained. The results showed that the four varieties of mung beans planted intercropping with a various spacing of maize showed different yield responses. Varieties of Vima-1 and Vima-3 gave the highest seed yields at a maize spacing of 60 cm x 30 cm. The Vima-2 variety was at a spacing of 90 cm x 30 cm, while the Kutilang variety was at 120 cm x 30 cm spacing. The four mung bean varieties were suitable for intercropping with maize with a yield/plot (NYi)> 0.5.
