Abstract

Nutrient Use Efficiency (NUE) of Maize is considered low. There are two important factors  responsible for this condition: (a) uniform fertilizer recommendation, (b) lack of consideration on soil variability, Indigenous Nutrient Supply and plant nutrient needs.  A method for studying low NUE and the capability of studying these two factors are urgently required. This study used Quantitative Evaluation of Fertility on Tropical Soils (QUEFTS) model. The main aim of this study was to employ and evaluate QUEFTS model for establishing site specific fertilizer recommendation in maize on the basis of farmer fields. Due to a unique characteristic of farmer field, it may be interesting to observe the pattern of soil fertility in relation to yields.  Six farmers fields and thirty soil samples were taken and analysed in the laboratory. The results showed that QUEFTS model was a valuable tool to make fertilizer recommendation by using yields as an integrated indicator. The results also showed that QUEFTS model was a promising method for establishing fertilizer recommendation for maize. The merits of model for determining Indigenous Nutrient Supply, nutrient yield limiting factors, balanced fertilizer recommendation show that QUEFTS model is a valuable tool for site specific fertilizer recommendation.   Keywords: QUEFTS, recommendation, site specific, yield

Abstract

The pathogenicity, development and reproduction of Steinernema sp., isolate Skpr-20/Str, were studied using Tenebrio molitor. Results revealed that pathogenicity, development and reproduction were significantly influenced by nematode doses. Although the number of invading IJs increased with increasing dose, percentage penetration declined. The IJs reached adulthood within 3 days. Females laid eggs from day 4-7. All eggs remaining inside uterus develop inside the maternal body. The first female bearing endotokia matricida was observed on day 5. In a sand-based assay, nematode was more pathogenic at lower dose instead of higher ones, where optimum dose was 80 nematodes per larva and average number of progeny per female was 5438. Under crowded conditions, development proceeds to IJ stage instead of the J3. The average length and width decreased with increasing of nematode doses. The IJ produced in cadavers infested with 640 nematodes per larva was significantly smaller (492 ± 6.4 µm) than offspring from other doses. The number of days which nematodes first emerged from the cadavers decreased with increasing dose. IJ first emerged at the average of 10-13 days at high IJ densities. It is concluded that the wide experimental characteristic of EPNs is also true for Steinernema sp., isolate Skpr-20/Str.Keywords: development, emergence period, endotokia matricida, entomopathogenic nematode, isolation, pathogennicity, Steinernema sp., isolate Skpr- 20/Str

Abstract

Research aimed to study the influence of phosphate rock-sulfur (PRS) content and inoculum ratios of biosulfo on P and S uptake and red onion yield on acid (Alfisol) and alkaline (Vertisol) soils.  Two factors evaluated were PRS content (0%, 60%, 80%) and inoculums of A.niger/P.nalgiovensis ratio of biosulfo (0:0, 1:1 and 3:1). As much of 12 kg of soil (Ø 2 mm) mixed thoroughly with biosulfo, basic fertilizer and manure, put into polybag then watering at field capacity moisture content. One bulb of red onion was planted to each polybag and incubated in the green house. The experiments arranged in completely randomized design with three replications. Variables observed included P and S uptake, and onion yield. Data analyzed with F test at 5% level of significant followed with DMRT if any significant influences. The result shows that the increases of PRS content as well as A. niger ratio of biosulfo tend to increase P and S uptake, especially on acid Alfisol.   Highest P and S uptake and onion yield were achieved with treatment combinations of P80I11, P80I31, and P60 I11 for Alfisol,   and  P80 I11,  P60 I11 and P60 I11  for Vertisol respectively.   Keywords:  phosphate, rock content, inoculums ratio,P and S uptake, onion yield

Abstract

Physic nut (Jatropha curcas L.) is a relatively new agricultural crop commodity in Indonesia. Hence, the thrips associated with this plant are not well recognized. The research objective was to provide information and tool for identification of thrips associated with physic nut. Survey method was conducted in some areas of Java, Madura, and Lombok island. The results showed that 10 species of thrips were found associated with physic nut. They belonged to nine genera and three family i.e. Thripidae, Aeolothripidae and Phlaeothripidae and one unidentified species. The Thripidae species were Selenothrips rubrocintus, Rhipiphorothrips pulchellus, Thrips hawaiiensis, Heliothrips haemorrhoidalis, Zaniothrips ricini and Scolothrips sexmaculatus. The family Aeolothripidae were Franklinothrips vespiformis, F. variegatus and Mymarothrips bicolor; the only one of Phlaeothripidae was Ecacanthothripstibialis. The identification key had been built for all species mentioned above. These thrips can be grouped into herbivore, carnivore, and fungivore.Keywords: Jatropha curcas, thrips, diversity

Abstract

Studies in transgenic sugarcane (Saccharum officinarum L.) demonstrated that sucrose transporter (SUT) genes were essential in sucrose translocations. Sucrose transporter gene isolated from sugarcane were designated as SoSUT1 and SoSOSUT2 respectively as encode protein of 518 and 747 amino acids. The genes were constructed into plasmid pYES2 for SoSUT1, and pYX112 for SoSOSUT2. cDNA SoSOSUT2 had also constructed into plasmid pBIN-At-GFP which was possible to trace the gene inserted. The constructed plasmid was transformed into yeast (Saccharomyces cerevisiae) and grown in minimal medium (SD–urasil) as selection medium. The transformed colony was confirmed using PCR. The functional expression was studied by growing yeast in YPD medium with 2% Sucrose, then the sucrose uptake was measured in number interval time using resorcinol method. The result showed that yeast INVSc1-pYES2-SoSUT1 and BF264- pYX112-SoSOSUT2 had higher ability in sucrose transport compared to the control-INVSc1 for SoSUT1 and control-BF264 for SoUT2. Moreover, the result showed that SoSUT1 had higher ability to transport sucrose than SoSOSUT2. Confocal microscope observation showed that transformation gene SoSOSUT2 was successful, which was indicated by green exposure of GFP protein.Keyword: sugarcane, sucrose transporter, yeast

Abstract

Growth and biochemical content of medicinal crops are influenced by agroecosystems characteristics . The objective of this research was to determine the optimum shading level and type of fertilizer as sources of nutrition on the growth, yield, and andrographolide content of sambiloto. The experiment used Split Plot Design with basic design of Randomized Complete Block Design arranged with two treatment factors, with three replications. The first factor as the main plot was shading levels, namely without shading, 25% shading, 50% shading, and 75% shading. The second factor as the sub plot was sources of nutrition reprented by type of fertilizer, namely NPK fertilizer, cow stable fertilizer, and compost fertilizer. The result of research indicated that shading level and the kind of nutrition influenced some growth and yield variables such as number of leaves, number of branches, plant height, plant dry weight and simplisia weight, and andrographolide content. Interaction of shading level at 25% and straw compost fertilizer performed best in growth characteristics, while the highest andrographolide content resulted from the treatment combination of 50% shading level and straw compost fertilizer.Keywords: fertilizer,nutrition, shading, andrographolide, Andrographis paniculata

Abstract

Mangosteen (Garcinia mangostana Linn.) dubbed as “finest fruit of the world”, has potential for both domestic market and export. However, this potential is threatened by low fruit quality caused by production of yellow latex and fruit scarring. The research objective was to obtain technology to reduce yellow latex and control Scirtothrips dorsalis, a pest that causes scarring on mangosteen. A randomized block design with four treatments and 14 replications was used in this research. Significant differences among the treatments were calculated using the Honestly Significant Difference (HSD) test. The results showed that treatment of drip irrigation system in combination with removing weeds under the canopy (A) or removing weeds followed by minimum tillage under the canopy (B) or removing weeds then covering with rice hay mulch under the canopy (C), where N, P, K, Ca, Mg fertilizer and yellow fluorescent sticky trap were applied could reduce scarring intensity and percentage of yellow latex on the fruit peel. However, the treatments did not significantly impact fruit diameter or percentage of yellow latex inside the fruit. Nevertheless, treatment C improved mangosteen quality by as much as 67.79% fulfilling export standard requirements.Keywords: Mangosteen, quality improvement, drip irrigation, yellow fluorescent sticky trap

Abstract

The damage and negative consequences of the Israeli Cast Lead on Gaza in the period between December 2008 - January 2009 is not only limited to the number of martyrs and wounded people, the destruction of houses and the infrastructure, but it also reached the environment. This paper investigates the occurrence of phosphorus (P) in the soil of the northern gover-norate of the Gaza Strip which has been shaped as a result of the heavily bombing of white phosphorus on Gaza during the war. We have measured soil Phosphorus concentrations in three different areas; agricultural, non-agricultural and urban areas. The obtained Olsen P values in most of the soil samples were ranked very high. The maximum value of phosphorous determined in agricultural areas was about 110.9 mg/ kg, in the non-agricultural areas adjacent to boarders 63.3 mg/ kg, and in urban areas 85.2 mg/ kg. The results show that the potential of phosphorus in the northern of the Gaza Strip is becoming higher than the allowed Olsen P values. Keywords: Phosphorus, Soil pollution, Olsen P, Gaza Strip

Abstract

The objective of this study was to identify the adaptability of twelve artemisia mutant genotypes, which were planted in three locations with different altitude, as a result of gamma irradiation. Randomized Complete Block Design (RCBD) was applied in this research with three replications as blocks. The genotypes 1B, 1C, 1D, 2, 3, 4, 5A, 6B, 7A, 8, 14, 15 and two control genotypes as parent genotype from seed and from in vitro were used. The genotypes were planted in three different locations such as Mount Putri, Cianjur (1450 m above sea level), Pacet, Cianjur (950 m above sea level) and Cicurug, Sukabumi (540 m above sea level). Based on the method of postdictive and predictive success, the model used was AMMI2 which was able to explain up to 100% of interaction-influenced variation. The genotypes which were found stabile and adaptive in these three locations were 1B, 1C, 1D, 6B and 15. Genotypes 3 and 7A were adaptive specifically in Pacet area, 5A was adaptive for Gunung Putri while genotype 4 was for Cicurug only.Keywords: AMMI, Artemisia annua, mutant genotype, adaptability
