Abstract

Rice (Oryza sativa L.) is largely cultivated in lowland area that vulnerable to flood occurrence. Root supposed to play an important role on rice tolerance to submergence stress. An experiment which conducted from January to May 2014 in Cikarawang Field Laboratory, Darmaga, Bogor, West Java aimed to study the role of root distribution on rice submergence tolerant. The experiment used Split Plot design replicated three times, with the depth of submergence as main plot and rice variety as subplot. The main plot consisted of  water depth of 5 cm (optimum), 50 cm, 60 cm and 80 cm from soil surface. The subplot consisted of four rice varieties, namely Ciherang, Inpari 30 (Ciherang Sub1), Indragiri and Margasari. Each plant was planted in a root box (30 cm x 40 cm x 5 cm) which put into container (67 cm x 47 cm x 42 cm) and placed into the pond with water depth as treatment. Submergence started when the plant was 39 DAS (Days After Seeding) for ten days. Observation conducted after the submergence stopped (49 DAS). Result showed that submergence retarded plant growth, root distribution and increase root damage for all rice varieties with the biggest effect on susceptible varieties.

Abstract

This research was aimed to study soil physico-chemical properties at four slope positions under oil palm plantation in Dharmasraya, West Sumatra, Indonesia. Soils were sampled at 0-20 cm soil depth from 4 different slope positions (upper, middle, lower slope, and the bottom or flat area). The parameters analyzed were soil texture, SOM, bulk density, total pore, hydraulic conductivity, soil water potential (physical characteristics) as well as soil pH, CEC, Al-exchangeable, basic cations (Ca, Mg, K), N, and P (chemical characteristics). The results showed that the bottom area had better soil physicochemical properties than the others. SOM increased by 33%, total pore by 19%, void ratio by 47%, plant available water (PAW) by 28%, soil pH-H2O by 41%, CEC by 171 %, total-N by 170 %, and P-potential by 114 %, in contrast, soil BD and exchangeable-Al were lower (20 % and 96 %, respectively) in the bottom than in the sloping land. The middle slope had the poorest soil physico-chemical properties after 26 years of forest conversion into oil palm plantation. All sites had clay texture, the clay content increased (R2=0.93) by lowering slope position, and so did SOM content (R2=0.86), soil CEC (R2=0.93), and soil total-N values (R2=0.76).

Abstract

Tungro is one of the most common diseases of rice plants which caused by double infection of RTBV (Rice Tungro Bacilliform Virus) and RTSV (Rice Tungro Spherical Virus), and it gives a significant economic loss. These viruses are transmitted by green leaf hopper (Nephottetix virescens. Distant), and the interaction between host plant and the viruses were still quite difficult to be fully understood. In order to look at whether there are any differences between the healthy and tungro infected rice, this study was set to examine the character differences between the infected and the healthy plants based on isozyme banding pattern. The infected plants were collected from three districts around Surakarta (Sragen, Sukoharjo, Klaten) followed by Polyacrilamide Gel Electrophoresis (PAGE) to evaluate the isozyme banding patterns. There were peroxidase, esterase and acid phosphotase isozymes used. The results showed that the real differences of isozyme banding patterns of both healthy and tungro infected plants were discovered. In all cases, the Tungro infected rice had thicker and more band numbers compared to the healthy one. This evident suggested that Tungro infected rice could be detected early using PAGE method.

Abstract

Upland rice usually gives poor germination under rainfed upland environement. To improve the seed germination, seed priming technique was assessed in this study. Seed of three upland rice (Oryza sativa L.) varieties (Leum Pua, ULR038 and Sakon Nakhon1, SKN) were primed with three different seed priming agents; distilled water, CaCl2 and 300-fold diluted wood vinegar. Compared to untreated dry seeds, wood vinegar improved field emergence and improved drought tolerance of the rice seeds better than other priming agents, which 50 % for Leum Pua, 20 % for ULR038 and 16% for SKN, when watering was delayed for 7 days. All three priming agents increased the field emergence percentage by similar amounts when watering was delayed for 14 days. To understand how priming helped improvement of germination, antioxidation mechanism and sugar metabolism were examined. Level of malondialdehyde was markedly reduced in all three rice varieties in response to priming, which were associated with increased activity of antioxidant enzymes, guaiacol peroxidase and ascorbate peroxidase. Wood vinegar also accelerated amylase activity in ULR038 and SKN, but not the sugar content. The results suggest that wood vinegar is a potent priming agent for achieving rapid and uniform seed germination in upland rice.

Abstract

Oviposition deterrent is chemical compounds which are used for avoiding eggs deposition. The oviposition deterrent resulted from eggs deposition is valuable information that can be manipulated for managing its population. The objective of this research was to determine the presence of oviposition deterrent resulted by female Bactrocera carambolae on mango. Extraction of oviposition deterrent was conducted by maceration method. The preference test was performed using two arms olfactometer, meanwhile the oviposition deterrent test was conducted by exposed gravid females to fruit that already smeared with extracts. The result revealed that gravid females of B. carambolae were attracted to methanol extract of 1 day after egg deposition, whereas the methanol extract of 3 and 5 days after egg deposition repelled gravid females. Oviposition deterrent test indicated that methanol extract at category 3 and 5 acted as a deterrent. The preference of gravid females of B. carambolae to different category of infested fruit extracts was probably influenced by the chemicals modification on mango after oviposition. This result suggested that the female B. carambolae do not deposit oviposition deterrent. The phenomenon of deterrence was probably as a result of chemical changes in fruit as a consequence of eggs infestation.

Abstract

Arrowroot (Maranta arundinacea L.) is an important starchy plant which has potential utilization for food,industry and medicine. The study was undertaken to assess the variability in morpho-physiological characters, tuber yield and starch content of 23 arrowroot populations in Garut District, West Java. The result showed some significant differences in morpho-physiological characteristics, tuber yield and starch content. Growth characteristics revealed that Cilawu population recorded the highest values for some characters: high, leaf number, above growth biomass and tuber biomass. Cikajang population showed the highest tuber yield (210.6 g per plant) followed by Cilawu population (134 g per plant). Cikajang and Cilawu populations also provided the highest tuber biomass, 46.6 g and 60.0 g respectively. Cilawu population was a second population producing the highest starch content (26.1 %) after Cibatu population (27 %). The higher heritability coupled with genetic advance revealed for fresh tuber yield indicated that selection on basis of the character may be helpful to improve arrowroot yield. Most of the growth characteristics had not significant correlation indicating that the characteristics are not good indicator for selection. Cilawu, Cikajang and Cibatu populations have good potential to produce the high quality and quantity of tuber for arrowroot cultivation in Garut District.

Abstract

One possibility to protect the maize from storage pests is by developing genotypes that resistant to maize weevil (Sitophilus zeamais Motsch). The research was aimed to evaluate the susceptibility of several maize genotypes including local variety to the maize weevil. Six genotypes i.e. SJA, G10-12-20, G10-1-3, G10-1-7, G10-1-20 and G10-1-17 and Tosari as local variety were used. No-choice assay under laboratory condition with observed variables was laid an egg and F1 progeny number, the median time of development and weight loss of infested kernel. The susceptibility index was assessed using Dobie’s susceptibility index. Results showed that the number of eggs laid by five females and infested samples weight loss were not significantly different between six maize genotypes as well as local variety. In contrast, the number of F1 progeny emerged was significantly different. Based on the susceptibility index, the maize genotype of G10-1-3 and G10-1-17 were resistant to the weevil. While other maize genotypes and local variety were considered as moderate resistant. Based on analysis of chemical and physical characteristic revealed that maize genotypes with higher of the total phenolic compound and physical hardness tend to resist from weevil damaged.

Abstract

Cilembu sweet potato is a unique commodity with high demand market due to its sweet taste. The objectives of this study were to investigate the production performance of Cilembu sweet potatoes in term of production classes and critical limit and to determine discriminating land characteristics classes of yield and total sugar content. This study was conducted in Cilembu sweet potatoes production centers in West Java. Sweet potatoes tuber and soil samples were collected by purposive random sampling during harvest. Cilembu sweet potatoes production classes were defined by decreasing yields criteria in land evaluation. Critical limit production was the lowest yield and total sugar content of raw tuber which harvested in Cilembu village. Discriminating land characteristics were decided by discriminant analysis. Results showed that there was a significant different yield between typical and nontypical areas. Critical limit of yield and total sugar content were 10.5 t ha-1 and 2.32 %, respectively. The discriminating land characteristics of yield classes were soil properties (pH, CEC, P, Ca, Mg, ΔT), and monthly rainfall, whereas for total sugar content classes were effective soil depth, clay, sand and monthly rainfall. These variables are proposed as diagnostic criteria in Cilembu sweet potato land suitability criteria.
