Abstract

This study was aimed to evaluate the effect of main crops harvest cutting height on the yield of rice ratoon in the tidal swamp by using direct seeding system. The experiment was conducted in Telang Sari village, District of Tanjung Lago, Banyuasin, South Sumatra Province from November 2013 to April 2014. It measured plots 4 x 5 m through a randomized block design with 5 replications. The treatment was main crops harvest cutting height of 10, 20, 30, 40 and 50 cm above the soil surface. The results showed that the effect of cutting height on rice ratoon yield depends on the condition of photosynthetic and the amount of remaining nodes on the main crops stubble as an emergence ratoon shoots. The main crops cutting height of 20-40 cm above the soil surface increased the number of productive tillers, grain weight per hill, yield per plot, ratoon ability to grow per plot, and the rice ratoon/main crops yield ratio in tidal land by using direct seeding system.

Abstract

This research aimed to determine the composition and pathotype distribution of Xanthomonas oryzae pv. oryzae (Xoo) in several rice producing centers in Indonesia during the growing season of 2010-2013. The studies were conducted into three phases of activities, namely: sampling and collection of infected leaves from the representative rice growing areas; isolation and purification of the Xoo isolates; and evaluation of composition and pathotype of Xoo on five rice differential varieties. Results indicated that a total of 2,658 isolates Xoo have been isolated from 10 provinces representing rice ecosystem in Indonesia during the growing season from 2010-2013. Evaluating these Xoo isolates against five differential varieties revealed that these Xoo isolates consisted of three pathotypes III, IV, and VIII with a total of 30, 36, and 34%, respectively. The data also indicated that two pathotypes III and IV were dominant in three provinces, while the pathotype VIII was dominant in four provinces. As mentioned previously, such information are useful in designing strategy of integrating components of technologies combined in the management of Bacterial leaf blight (BLB) occurrences in a particular endemic areas.

Abstract

An effort to increase the yield and reduce carbon loss from maize farming practices on Ultisols largely depend on fertilizer inputs and in situ crop residual management. The experiment aimed to estimate yields, biomass production and carbon dynamics of several management fertilization on maize farming practice on Ultisols has been conducted from March to July 2013 in Taman-bogo Experimental Farm, East Lampung. The experiment was set up as a randomized complete blockdesign, consisted of 6 treatments namely: 5 t ha-1 of cattle manure, 5 t ha-1of dried sludge manure, and its combination with 200 kg urea ha-1 + 125 kg SP36 ha-1 + 50 kg KCl ha-1 (50% of recommended dose of inorganic fertilizers “RDIF”) and 75% of RDIF. The experimental results revealed that application of combined organic with inorganic fertilizers increased the biomass production, carbon fixation, and grain yield significantly. More than 50% of produced biomass and fixed carbon (grain, maize cob, maize husk, stems and leaves) were removed from maize farming. The use of organic fertilizer combined with NPK fertilizer at 50% of RDIF can be applied to increase the biomass production, organic carbon fixation and maize grain yield in sustainable ways.

Abstract

Fungi has been tested as one of the potential control agents for insect pests, which raises hopes for developing fungi as good biopesticides. The high variation within fungi species made taxonomic identification procedures more complex, thus molecular identification techniques are needed in addition to traditional morphological characteristics currently used as primary methods to classify fungi species. The objective of this research was to identify the species of the most pathogenic fungi to Tetranychus kanzawai Kishida using RAPD-PCR.  The internal transcribed spacer of 5.8s rDNA (ITS-5.8s rDNA) sequence of these fungal isolates were amplified using two sets of universal primers for ITS and then analyzed. Molecular identification showed that these  isolates had a higher  of similarity to Metarhizium anisopliae than Metarhizium flavoviride.

Abstract

Private forest in Java Island is mainly managed by Agroforestry (AF) system. There are three levels in AF systems: early AF, middle AF, and advance AF. The land productivity in AF system by villagers is mostly low because of inappropriate AF practice. The objective of this research is to analyze the land management practice in Menoreh hills, Kulon Progo, Yogyakarta. The study was conducted in Giripurwo Village, Kulon Progo. Stratifed sampling with purposive sampling was used in this study. Total of twelve plots were determined in every AF levels. Studies conducted in every plot includes the species composition and soil fertillity. The results showed that: (1) Tree composition in early and middle AF is dominated by woody tree (Sengon), while in advance AF is dominated by non-timber forest product (clove), (2) Low soil fertility in the study area is caused by high intensity of biomass harvesting and low fertilization dosage applied, (3) The increment of land productivity could be achieved by increasing the biomass input to the soil from organic fertilizer and crop waste.

Abstract

Palm oil mill contributed a significant benefit to agro-based industry and social-economic for Malaysia. Palm oil mill effluent (POME) is considered as a polluted wastewater and the treated POME sludge was produced from the open treatment ponds. The objective of this study was to determine the physicochemical characteristics of treated POME sludge and its potential as an organic fertilizer. It was collected from the dumping ponds in Felda Jengka 8, palm oil mill. Physicochemical characteristics, sampling and preparation of samples were analyzed according to the standard method of soil and the wastewater. The samples were collected after one and six month of age with different depths (one, two and three meters). The statistical analysis revealed that the depth was not significant on the physicochemical characteristics. The characteristics of the treated POME sludge was measures using CHNS-O, C/N ratio, solid analysis, heavy metal, macro and micronutrient, moisture content, and pH. However, the elements of oxygen, iron and pH were shown an interaction effects with time. In conclusion, the treated POME sludge has shown significant effect and the potential used as an organic fertilizer. Indeed, further studies on crops response are being conducted to prove the findings.

Abstract

In Indonesia, apple orchards are decreasing because of leaf blotch disease. Marssonina leaf blotch has not been widely known and the problems are associated with the incidence of the epidemic so they need to be studied. Research aimed to investigate the biological aspect of Marssonina leaf blotch, the resistance of apple varieties and the alternative host of Marssonina coronaria, and the interactions between Marssonina leaf blotch and weather factors. The research was conducted in laboratory, greenhouse and on apple orchard respectively. There are three results in this research. First, fruit bodies (apothecia) are not produced by fungus, but only conidia (imperfect form) are. Second, based on bioassay, pathogen survives only on the apple. Finally, there are three formula can be used to predict the leaf blotch disease, such as:1) Y=-37.91+19.98X6 (population of spores in the air),2) Y = -438.13 + 25.71X1 (temperature) -3.05X2 (humidity) + 41.07X3(wind speed) -2.07X4 (sunlight) + 19.25X5 (rainfall), and 3) Y = -43.86-1.61 22.60 X5 (rainfall) + X6 (population of spores).

Abstract

The hinterland of Jakarta has experienced high pressure in its land utilization due to Jakarta’s rapid development. The objective of this research was to analyse the suitable land available for agriculture. The research was conducted in Bogor, a hinterland regency of Jakarta. The methodology used includes two steps of analysis, which are land suitability and land availability analysis. Land suitability for agriculture was analysed using multi-criteria decision making method. Seven (7) criteria were included, which consist of soil class, land capability class, slope, elevation, slope aspect, land use/land cover and distance to roads. The criteria were weighted using the Analytical Hierarchy Process. Combining criteria weights and sub-criteria scores, an overlay model in Geographic Information System was applied. The result from land suitability analysis was used as a feed for determining land availability, considering the forest area status and land allocation in the official spatial land use plan. The results indicate that an area amounting to 87.5% of Bogor Regency is suitable for agriculture. Land which is suitable and available for agriculture is 16.7% of the regency’s area. Considering available land which is currently in use, the area that can be allocated for the expansion of agriculture is 3.3%.

Abstract

Information about genetic relationship and genetic diversity are an inevitable need in mango breeding program. Base substitution value, genetic distance and grouping of 15 mango accessions based on accessions in chloroplast DNA (cpDNA) among 15 mango accessions were assessed. The samples were originated from Mango Germplasm, Cukur Gondang Research Station of Indonesian Tropical Fruits Research Institute, Pasuruan, East Java. Sequencing of Chloroplast DNA was used to obtain nucleotide sequence data. Paired specific primer rpl20 F - rps12 R and atp F - rbcL R were used for amplification of non-coding area of mango DNA chloroplast and sequencing processes as well. All data were analyzed using Software MEGA 6. The result showed that total numbers and nucleotide base sequences varied among all accessions. All accessions were grouped in five different clusters that might be used as source of parental breeding.

Abstract

The study was conducted to investigate the impacts of fertilizer application on soil properties in Kaharole upazila of Dinajpur district in Bangladesh. Samples were collected to analyze the variation of soil nutrients in three cropping seasons: season-1 (March-April, 2013), season-2 (August-September, 2013) and season-3 (January-February, 2014). In each season 10 samples, 6 from conventionally cultivated soil (CCS) and 4 from organic fertilized soil (OFS), were collected from 10 randomly selected sampling points. The study observed acidic soil pH in all three cropping seasons, while soil pH was decreasing gradually with fertilizer application. The results of the study clearly depicted that all the soil nutrient contents and OM decreased with the application of fertilizers in different cropping seasons except Zn and Fe. The OFS contains relatively higher amount of OM and essential nutrients than CCS except Fe and Zn. The study shows that the continuous application of fertilizer in agricultural lands reduces soil fertility evolving nutrient deficiency in the soil; resulting in reduced crop productivity.
