Abstract

The study of biological agents in controlling plant disease has discovered many potential microbes with various mode of actions. In the end, these potential microorganism should qualifiedly fulfill several requirements before they are formally stated for commercialization and wider implementation. Evaluations on their physico-chemical characteristics and viabililty after certain storage period were needed to ensure the effectiveness of the product during transportation and commercialization process. The research was aimed to evaluate B. subtilis strains B7 and B30 for their physio-chemical characteristic and viability after six months storage and investigate the efficacy of the strains against soft root disease of Phalaenopsis. The results showed that both antagonists had stable perfomances in physico-chemical, viability and efficacy evaluations after six months storage. The existence of active bacteria was demonstrated from the decrease in pH, murky suspensions and foul smelling as indications of fermentative reactions under optimal and minimal nutrients. Both antagonists showed stable viability after storage and effectively inhibited soft rot disease when applied on the infected plants with slightly lesser supression from streptomycin sulphate.

Abstract

The purpose of this research was to evaluate the safety of mixture formulations of Tephrosia vogelii and Piper aduncum at various storage temperatures and their insecticidal activity against C. pavonana larvae. Formulations were made from T. vogelii and P. aduncum (1:5) in emulsifiable concentrate (EC) and wettable powder (WP) form. Both formulations have strong insecticidal activity against C. pavonana. This research used a randomized completed design in different temperature treatments. Insecticidal activity of formulations after storage was tested against C. pavonana. The treatments were done using deep leaf method in 5 concentrations and 5 replications. The results showed that LC95 value of EC formulation after storage at condition: below 4°C, room temperature, and 40°C were 0.19%, 0.34% and 0.21% respectively. Based on LC95 value of EC formulation from each treatment, indicated that EC formulation after storage could hold insecticidal activity as good as insecticidal activity before storage due to LC95 value after storage relatively lower than LC95 value before storage (0.35%). In the contrary, WP formulation activity was significantly decreased in all treatments compared to WP formulation activity before storage based on LC95 value.

Abstract

The research aimed to develop a rice cell culture system with high proliferation and screening resistant cell lines of rice to bacterial blight disease caused by Xanthomonas oryza pv. oryzae (Xoo). The culture cells obtained from the callus, cultured on CS-1 medium containing 3 % sucrose and 2 mg L-1 2,4-D for 4 weeks. The results showed that proliferation cell was signifcantly increased 1-fold in 3 weeks of primary culture in CS-1 conditioned medium (fresh/spent medium ratio 1:1) containing 3 % sucrose, 0.5 % glucose, 0.05 % fructose and 2 mg L-1 2,4-D. This medium was used to screen the cell lines through applying culture filtrate of Xoo. The method was to find a novel cell line which could produce high amounts of reactive oxygen species (ROS). Screening results showed 33 % cell lines were strong ROS-producing, two cell lines were selected and cultured for second round screening. The ratio of strong ROS-producing cell lines was increased up to 67 % in the third round screening. The strong ROS-producing cell lines in third round screening can be further cultured for plant regeneration. The rice cell lines with high ROS production may have potential of resistant cell lines against Xoo.

Abstract

Liquid smoke is reported to be effective to inhibit some bacteria. The study aimed to evaluate the effects of liquid smoke (LS) from coconut shell (CS-LS), pinecone (P-LS), and oil palm branch (OPB-LS) on the incidences of blood disease, induced resistance to Ralstonia syzygii subsp. celebesensis, and plant growth. Two days after banana seedlings were treated with LS, ethylene, auxin, lignin, activities of the enzymes of peroxidase (POD) and phenylalanine ammonia lyase (PAL) on the root of the banana seedlings were measured. Then, the seedlings were inoculated by R. syzygii subsp. celebesensis. The plant growth and incidence of blood diseases were observed daily and the 31st day after the application of LS and this bacteria inoculation. The results showed that the CS-LS, P-LS, and OPB-LS at all tested concentration could suppress the incidence of blood diseases up to 100 %, induce resistance of banana seedlings to the R. syzygii subsp. celebesensis with increased levels of ethylene, auxin, lignin, activities of POD and PAL, and plant growth, significantly. Based on the effectiveness of this bacterial control and the ability to promote the growth of banana seedlings test, it is recommended that the most effective treatment is P-LS 0.5 %.

Abstract

The research aims to study the use of fly ash for improving the growth and yield of rice in peatland. The peat soil material that used in this study was sapric weathering level. The field research was designed by using a completely randomized design. The treatment in this study was the application of fly ash consisting of six levels (0, 25, 50, 75, 100 and 125 g fly ash per pot), each treatment repeated 4 times. The results showed that the best plant growth and yield of rice were gained from the application of fly ash at the lower dose (25 g pot-1 and 75 g pot-1, respectively). The increase in fly ash dose (100 g pot-1 and 125 g pot-1) did not gave the highest rice yield (9.67% and 0.2% lower than the dose of 75 g pot-1) due to the macronutrients N, P and K as a limiting factor (only as a basic fertilizer).

Abstract

This research aimed to study the compatibility of some Trichoderma spp. isolates on some synthetic chemical pesticides carried out at the Laboratory of Plant Protection, Faculty of Agriculture, Jenderal Soedirman University from April up to July 2014. Trichoderma isolates were derived from rhizosphere exploration on ginger, banana, pineapple and shallot. The synthetic pesticides used were mancozeb and propineb (fungicides), oxytetracycline and streptomycin sulfate (agrimycin, bactericides), carbofuran (nematicide), and deltamethrin and prefenophos (insecticides: synthetic pyrethroids and chiral organophosphates, respectively). The compatibility test used food poisoning method in a completely randomized design with three replicates. Variables observed were discolouration, sporulation, colony diameter, conidia density, and fungal growth at pesticides treatment. The data were analyzed by F test at 5 % significant level and continued by Duncan Multiple Range Test (DMRT) when there was a significant difference. The result of the research showed that the most significant decreasing of Trichoderma spp. was found on mancozeb for shallot, ginger, and banana isolates, and propineb for pineapple isolate, respectively, 89.4, 97.7, 93.3, and 95.2 %. This result was in line with colour, sporulation, and inhibition level observation.

Abstract

Optimum harvest time and yield gap information are important aspects of grain quality optimization and production development. The World Food Studies (WOFOST) crop simulation model was studied in its application for soybean optimum harvest time and yield gap analysis in East Java, Indonesia. Data inputs were local weather of solar irradiance and daily temperature, with given soybean varieties provided in the WOFOST simulation. The simulation result was validated with the actual data using homogeneity test of regression coefficient. Result showed that differences between simulation and actual yield were insignificant (α=0.05), for each tested locations and soybean varieties. The average potential yield was 1,716 kg ha-1, where the highest was obtained from S-France 904 variety located in Malang Regency. The optimum root mean square error was 49.42 kg ha-1 with correlation coefficient of 0.918. Meanwhile, the optimum harvest time and yield gap have corresponded to the actual data where harvest time was at the shortest in Blitar Regency using N-France 901 and N Spain 903 varieties, while the average yield gap was 33%. In conclusion, WOFOST simulation model has a prospect to be applied further using local soybean varieties followed by validation in the whole East Java region.

Abstract

Pinang nut (Areca catechu L.) is a major agroforestry crops in Papua with high economic value. This study developed allometric equations for estimating Pinang biomass on the basis of stem diameter and height by destructive sampling inagroforestry systems. Aboveground biomass was measured and linked to plant stem diameter at various heights (0.13 and 130 cm above the ground) and plant height. The resultant equation was used for biomass estimates in various agroforestry systems with Pinang trees, with total of 18 plots differentiated in bottom, middle and upper slope positions. As expected for palm trees, plant height is a better predictor (Y = 0.816 H1.42; R2 = 0.89) of biomass than stem diameter, with equal results for diameter measurements at 13 or 130 cm height (Y = 0.0689 D2.59; R2 = 0.74). Best results were for an equation combining diameter and plant height: Y = 0.03883*H*D1.2; R2 = 0.96. Agroforestry systems on the upper slopes had the highest carbon stocks (38.8 Mg ha-1) than the middle and lower slopes (25.9 and 22.5 Mg ha-1, respectively). Aboveground carbon stocks of Pinang in study area ranged from 0.96 to 20.9 kg C tree-1 with an average of 10.1 kg C tree-1.

Abstract

Selection of varieties and number of seedlings per hole in rice plants is closely related to the shape of canopy, the rate of plant growth and the age of plant which determine the ability of plants to intercept and absorb solar radiation intensity. This research aimed to improve the Radiation Use Efficiency of rice by selecting plant canopies based on varieties and number of seeds per hole. Research was conducted from November 2015 to May 2016, in Landak Regency, West Kalimantan. A Split Plot Design with three replications was adopted to evaluate three varieties (Sembada-168, Inpari-30, and local varieties) as main plot, and the number of seedlings per planting hole (one, three, five, and seven seedlings per planting hole) as sub plot. Result showed that there was no interaction between varieties and the number of seedlings per hole to Radiation Use Efficiency (RUE) on rice. RUE on local variety was lower than Sembada-168 and Inpari-30. One seedling per hole had higher RUE than seven seeds with value of 3.36 and 2.17 % respectively. The number of seedlings showed that RUE of one and three seedlings per hole were higher than seven seedlings per hole.

Abstract

Local culture and traditions have been considered as an important factor in influencing plant species diversity and composition of home garden, but their interactive effect have not yet been investigated. This research aimed to describe the plant species diversity in traditional home gardens, identify the species with important value based on ethnobotanical indices, and describe the perception of local people towards agroforestry conservation in Osingnese Villages in Banyuwangi. Data acquisition was performed at Kopen Dukuh, Buluhsari-Kopen Cungking, and Kemiren Villages. Floristic survey was implemented at 75 home gardens. An interview was implemented for each owner. Results showed that Osingnese home gardens consist of numerous plant species. Kopen Dukuh and Buluhsari-Kopen Cungking showed a complex structure which could be considered as a complex agroforestry. Cocos nucifera, Coffea canephora, Coffea liberica, Garcinia mangostana, and Durio zibethinus were the important species in complex agroforestry. Those species composition indicated that home gardens are able to conserve native plants of Malaysian regions, particularly Indonesian flora. Agroforestry knowledge was derived from the older generations and implemented in gardening practices. They also argued that recent agroforestry is an adaptation mechanism of land management. The government did not contribute to educate and empower local people about agroforestry practices.
