Abstract

Trizelia, Busniah M, Agung Permadi A. 2017. Pathogenicity of entomopathogenic fungus Metarhizium spp. against predators Menochilus sexmaculatus Fabricius (Coleoptera: Coccinellidae). Asian J Agric 1: 1-5. Metarhizium spp is an entomopathogenic fungus which has wide host range. Metarhizium spp can not only infect insect pests, but can also infect beneficial insects such as predators. The pathogenicity of four isolates of Metarhizium spp. was investigated against Menochilus sexmaculatus predator. Isolates of Metarhizium spp were isolated from rhizosphere of cacao, cabbage, chili, and rubber crops. The experiment was conducted by treating the fourth instar larvae with an appropriate conidial suspension of 108 conidia mL-1. The results showed that all isolates of Metarhizium spp were pathogenic toward beetle predator M. sexmaculatus. Mortality of larvae within seven days after application of conidial suspension varied between 27.50 to 67.50% and there were statistically significant differences among the tested isolates. Metarhizium spp. had also a significant affect in reducing pupation and adult emergence of M. sexmaculatus to below 30% and 3%, respectively. These studies indicate that entomopathogenic fungus Metarhizium spp was pathogenic to beetle predators, M. sexmaculatus.

Abstract

Apriyana Y, Sarvina Y, Dewi ER, Pramudia A. 2017. Farmer adaptation strategy in paddy field affected by climate variability in monsoon regions. Asian J Agric 1: 9-16. Adaptation of agriculture cultivation to climate variability and climate anomalies both in paddy field especially in monsoon regions is one of the strategies to minimize the impact of these two phenomena to reduce the economic loss, particularly for food security in Indonesia. The objectives of this study are: (i) to identify onset and cropping pattern in irrigated land, rainfed and dry land in affected area due to climate anomalies, (ii) to collect information on carrying capacity water resources and adaptation practices applied by farmers and, (iii) to identify strategies for farmers on irrigated land, rainfed and dry land in the region affected by climate variability. The desk work analysis and field survey were conducted in Serang District, Banten Province, Subang District, West Java Province and Pati District, Central Jawa Province, Indonesia. The study was undertaken in three cluster activities i.e. (i) correlation analysis of climate anomalies and rainfall, (ii) field survey and, (iii) analysis of onset planting season, cropping pattern, water availability, the best planting time and irrigation schedule. The results showed that the farmers in affected area due to climate variability could adapt by shifting the onset of planting season. Farmers in irrigated lands changed their onset around 2-4 ten-days period to October II - December II. Furthermore, in rainfed areas, the onset around 4-6 ten-days period was shifted to November I - January III. For dry land their onset around 6-8 ten-days period was moved to November II - February I. The cropping pattern rice-rice-palawija/fallow was applied on irrigated land. Furthermore, the pattern of rice-rice/palawija/fallow-fallow was carried out in rainfed. Finally, the pattern of palawija-palawija/fallow-dormant was performed on the dry land. Adaptation programs dealing with climate variability in Serang and Pati Districts varied more than in Subang District. In Serang and Pati, during the first planting season, farmers applied irrigation roughly 20%-30% of water pump from the river and during second planting season, farmers in Pati District used water from well-pump, as well as in Serang that can reach 100% of the application.

The aim of this study was to know the reproduction aspects of nilem (Osteochilus vittatus Valenciennes, 1842; syn. Osteochilus hasseltii Valenciennes, 1842). The study was conducted from October 2015 to March 2016 that includes elements of body length, weight, gonad maturity level (GML) and fecundity. There were 27 samples collected from farming activities in Cianjur, Tasikmalaya and Kuningan West Java, Indonesia. The parameters observed were the correlation between weight and fecundity, correlation between body length and fecundity and GML. The method used was explorative approach and the data were analyzed by descriptive approach. The results showed that the correlation between weight and fecundity in Cianjur District was y= e0,024x, while the body length and fecundity was y=e0,413x. In Tasikmalaya District was y= e0,0728x, while the body length and fecundity was y=e0,4903x. In Kuningan District was y= e0,2902x, while the correlation between the length of the fish and fecundity was y=e0,6859x. The dominant gonad maturity level of Nilem in Cianjur was GML IV (50%), Tasikmalaya was GMLVI (100%), and Kuningan was GML V (55,56%) respectively. The relationship between length and body weight of Osteochillus vittatus from Cianjur, Tasikmalaya and Kuningan District were W=0,03L2,95, W = 0.04L2.89 and W = 0.04L2.79 respectively. The implication of this research is to know the proper size of nilem fish that can be harvested in conditions of optimum egg volume.

Abstract

Mohammedaltom AAA, Dagash YMI. 2017. The effect of fertilizer type and time of application on growth and forage productivity of mung bean. Asian J Agric 1: 22-28. A field experiment was conducted on April 3, 2016, at the Demonstration Farm of College of Agricultural Studies, Sudan University of Sciences and Technology, Shambat, Khartoum, Sudan to study the effect of some fertilizers and their time of application on growth and forage productivity of mung bean. The treatments were arranged factorially in split-plot trial with four replications. Application time was assigned to the main plot as three times of application: before sowing, with sowing and after sowing. Types of fertilizers as the sub plot including four types of fertilizers: without fertilizer (control), 50 kg ha-1 (organic manure), 100 kg ha-1 (diammonium phosphate), and 10 L ha-1 (humic acid). Different characters were measured include plant height (cm), stem thickness (cm), number of branches/plant, number of leaves/plant, fresh weight/plant (g) as well as dry weight/plant (g). The results revealed that there is a highly significant difference for types and application time of fertilizers and their interaction on plant height, number of leaves, and fresh forage and dry forage. Highly significant differences (p ≤ 0.01) were recorded in types of fertilizers and interaction between different application time and types of fertilizers for number of branch and significant difference (p ≤ 0.05) of application time for number of branch and stem diameter. There was no significant difference in types of fertilizers for stem diameter. The highest height of the plant (28.78 cm), the highest number of branches/plant (9.37), the maximum stem diameter (6.43 cm), the largest number of leaves/plant (31.69), the best fresh weight (815 kg ha-1) and dry weight (161 kg ha-1) were recorded for the treatment of 50 kg ha-1 organic manure applied after sowing.

Yustiati A, Andriani Y, Herawati T. 2017. Sustainable aquaculture development in floating nets at Cirata reservoir (West Java, Indonesia) through single-sex nilem fish introduction. Asian J Agric 1: 29-34. This research aims to develop a sustainable aquaculture system using single-sex nilem fish in trophic level-based farming and to analyze the feeding habits, types of meal and preference level of the feed in nilem farmed in Cirata Reservoir. In addition, it also aims to determine the fish's ability as a biocontrol agent for water cleaning by measuring the ability to utilize periphyton attached to the floating nets. Research conducted at the Laboratory of Ciparanje, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran and floating nets of Cirata reservoir. Observation of the performance of biological testing and food feeding applies the experimental design method of Completely Randomized Design (CRD) consisting 5 treatments and 3 replications. The five treatments include non-artificial feeding (treatment A), 1% feeding of body weight per day (treatment B), 2% feeding of body weight per day (treatment C), 3% of feeding of body weight per day (treatment D), and 4% feeding of body weight per day (treatment E). The results showed there was no difference in the survival and growth levels of the female single-sex fish given both commercial and non-commercial feed. The highest feed efficiency was observed in the 3% of commercial feeding treatment, amounting to 55.30%. The fish are herbivorous and generalist with trophic levels between 1.03% and 1.45% eating planktons for living. Fish fed with artificial food to 4% of the biomass still graze on phytoplankton as the main source of food, but adapt by changing the natural feeding and tend to be ineffective in utilizing the available food resources in the waters. During the study, the types and amount of periphyton attached to the nets have decreased. Higher commercial feeding level results in the higher density of periphyton in the floating nets.

Abstract

Samanhudi, Purwanto E, Sulandjari, Setiyaningsih A. 2017. Microclimate modification through shading and watering frequency treatments as efforts for ex situ conservation of pule pandak (Rauvolfia serpentina). Asian J Agric 1: 35-39. Pule pandak (Rauvolfia serpentina Benth) is one of the rare medicinal plants. Exploration of nature continues to be done to meet the needs of the drug. That is why proper cultivation technique for pule pandak is required, by giving appropriate shading level and watering frequency to the growth and yield of pule pandak. The research aimed to examine the effect of shading and watering frequency on the growth and yield of pule pandak. The study was conducted from February to July 2009 in BBP Mondromino, Pokoh Village, Wonogiri at 141 meters above sea level. The experimental Design used in this research was a Split Plot Design consisted two factors and three repetitions. The first factor (main plot) was shading level consisted of three levels: 55%, 65%, and 75%. The second factor (sub plot) was watering frequency consisted of three levels: once three days, once five days and once seven days. Data were subjected to analysis of variance, followed by post hoc test of Duncan Multiple Range Test at 5% level. The reserpine content was analyzed descriptively. The results showed that no interaction between shading level and watering frequency on all variables. The shading level caused no significant effect on growth and yield of pule pandak except the leaf area. Watering frequency caused no significant effect on growth and yield of pule pandak except the chlorophyll content. The results showed that plants treated with watering frequency of five-day interval produced the highest chlorophyll content. Plants treated with shading level of 65% and watering frequency once five days produced the highest reserpine content.

Abstract

Suyadi, Rosfiansyah. 2017. The role of plant parasitic nematodes on productivity reduction of banana and tomato in East Kalimantan, Indonesia. Asian J Agric 1: xxxx. Plant parasitic nematode is one of the most limiting factor of agricultural ecosystem productivity in East Kalimantan, but their occurrence in agricultural field as a crop’s pest generally undistinguished, due to their microscopic size and their existence wrapped in the roots or soil particles. However, plant parasitic nematodes might cause yield loss up to 75%, without showed any disease symptom on crop morphologically. Perennial crop and annual crop under intensive cultivation usually experience high yield loss due to plant parasitic nematodes, if crop protection management was not implemented properly. This research aimed to determine the role of plant parasitic nematodes in reducing crop’s productivity in East Kalimantan, in relation to agricultural practices implemented by farmers. A descriptive research and comparative analyses were implemented to determine the role of plant parasitic nematode on yield reduction of banana and tomato as the indicator of productivity. Based on the field observation related to pest management in East Kalimantan, it was determined that plant parasitic nematode existence was neglected by farmers and no significant effort was implemented to control plant parasitic nematodes population. Therefore, low productivity of agricultural ecosystem in East Kalimantan was reported by Statistical Office, and it was not only caused by soil fertility problems, in some crops it was also the impact of population outbreak of plant parasitic nematodes. The first ranking three genera of plant parasite nematodes observed in East Kalimantan were Meloidogyne, Radhopholus, and Rotylenchulus, respectively. Meloidogyne and Rotylenchulus were major pest on vegetables, and caused yield loss >50% on tomato. While, genus of Radhopholus was the major pest on banana, and caused yield loss >75% on banana.

Abstract

Sheriff O, Alemayehu K. 2017. Review: Genetic diversity studies using microsatellite markers and their contribution in supporting sustainable sheep breeding programs. Asian J Agric 1: 46-51. Microsatellites have been widely accepted and employed as useful molecular markers for measuring genetic diversity and divergence within and among populations. The various parameters developed so far to measure genetic diversity within and among populations are observed and expected heterozygosities (Ho and He), the mean number of alleles per locus (MNA),polymorphic information content (PIC), genetic distance and phylogenetic or tree building approach.The objective of thisreview was therefore to quantifythe genetic diversity studies of domestic sheep populations using microsatellite markersand their contribution in supporting sustainable sheep breeding programs. From the review, it is possible to see that there was high within population genetic variations in all the studied sheep populations, poor level of population differentiations and high levels of inbreeding. On the other hand, low estimates of hetrozygosities and mean number of alleles and employing only few and weak markers were observed in some of the studies. The gaps observed in the previous genetic diversity studies of the sheep populations may demand further works to reveal more information on the population structures andto start appropriate and sustainable breeding programs.

Abstract

Faizal I, Emdi A. 2017. Analysis of flowering gene in palm oil (Elaeis guineensis). Asian J Agric 1: 53-58. Palm oil has always been an important commodity in Indonesia. The most common species is palm oil, Elaeis guineensis. Palm oil is a monoecious plant with a tendency to be a temporal dioecious. Female flower will be the one that produces palm oil fruit, that later is treated with palm oil while male flower only takes part in the fertilization process. In order to know the ratio between female and male flower tree in a plantation, this study was performed to detect a distinction between female and male flowering gene sequences from DNA sample of E. guineensis. Based on previous study which managed to characterize MADS-box gene of palm oil, a primer was designed and named GmG (Globosa-male-Gaps). The result shows that the primer has the ability to differentiate DNA sequence female and male flower of E.guineensis, Palm oil. However, further studies with full sequence and more samples are needed to find distinctive results between female and male flower sequences as the GmG primer could be used to design a specific marker or primer to detect the presence of female or male flower within a tree.
