Information on characteristics related to drought tolerance is particularly important for improving hybrid maize yield. The present study was conducted with 62 genotypes involving tolerant, moderate, susceptible and very susceptible, for post flowering drought tolerance of hybrid maize. An experiment was conducted to determine the characteristics association between grain yield and its components and their direct and indirect effects to the yield. The research was arranged in a randomized completed block design with three replications. Drought stress treatment was started from flowering (50 days after planting, dap) until milk-dough stage (80 dap). The result indicated significant and positive association of grain yield with plant height, ear position height, stalk diameter, leaf area, leaf angle, the percentage of leaf senescence, leaves rolling score, ear length, ear diameter, number of grain/ear and shelling percentage were correlated with the yield under drought stress. Grain yield was strongly correlated with plant height, leaf area, ear length, ear diameter, and shelling percentage. Indirect effect on grain yield under drought conditions were found for the following parameters: stalk diameter, leaf angle, percentage of leaf senescence, leaf rolling scores and number of seeds/ear.

Pineapple, papaya and cempedak are horticultural commodities that are perishable, require large space, and are usually consumed in fresh form. Based on that, technologies are required for processing them, and one alternative is juice technology. To ensure that the juice is still suitable for consumption and unspoiled, information on shelf life is necessary. Method of estimating shelf life used is ASLT (Accelarated Shelf Life Test). This research was conducted at the Laboratory of The Indonesian Center for Postharvest Agricultural Research and Development between September 2012 â€“ January 2013. Results showed that kinetics reaction in the deterioration of vitamin C in pineapple and pineapple-Cempedak juice followed order one reaction. At storage temperature ranging between 30 Â°C to -5 Â°C pineapple-cempedak juice showed a shelf life longer than the shelf life of pineapple and pineapple-papaya juices. The estimated shelf life of pineapple-cempedak juice at a temperature of -5 Â°C was 197.85 days. Shelf life of pineapple-papaya juice at a temperature of -5 Â°C was 172.39 days. Shelf life of pineapple juice at a temperature of -5 Â°C was 156.85 days.

Paddy loss during harvest and postharvest handling is a complicated system involving many elements, and they are inter-connected. Therefore, to overcome these issues, appropriate and sustainable strategies should be implemented. The purpose of this study was to analyze the leverage factors that can overcome the problems of post-harvest losses of rice by a dynamic system approach as a basis in formulating policy strategy. This research was conducted in Indramayu, West Java, from January to December 2012. The methodology used in this research was modelling system approach. Primary data collection was conducted by a questionnaire survey and interviews with stakeholders and farmers as respondents. Secondary data collection was obtained from the Central Bureau of Statistics Centre (Jakarta) and regional (West Java), Regional Agriculture Services, Regional Industrial and Trade Services, Regional Population and Civil Registration Agency, Center for Agricultural and Food Security Agency. The results showed that the reduction of rice losses could be approached in two ways: technical approach and cultural approach. The technical approach could be developed by implementing a quality management system such as GHP and GMP, while the cultural approach could be implemented by creating new jobs. Application of the quality system would also encourage the revitalization in rice milling so that it would increase the yield, and so the application of the quality management system would contribute greatly to the production of dry unhulled rice as well as rice in Indramayu. The implementation of this strategy must consider the ability and readiness of the district, so that the strategies could be more realistic and easier to be implemented. The simulation results showed that the implementation of the strategy by using harvest and postharvest equipments to be accompanied by the implementation of GHP and GMP, may decrease shrinkage ranging from 5.58% to 10.14%, or the equivalent of rescuing MPD from 61,240 to 115,859 tons in 2020.

Land conversion causes competition in land use, and thus it is necessary to select leading commodities based on agro ecological zoning (AEZ). This study aimed to determine the leading commodities of food crops in Bantul Regency agro ecological zone. This study was conducted on March 2015. The data used was time series data of food crops harvested between 2008-2012 and agricultural commodities zone maps year 2013 based on AEZ with scale 1:50.000 obtained from the Statistics of Indonesia, Agriculture and Forestry Office, and AIAT. Commodities with comparative advantages were analysed by Location Quotient (LQ) while commodities with competitive advantages were analysed by Shift Share Analysis (SSA). Leading food crops commodities were determined through an overlay process using the ArcGIS software covering analysis results of LQ, SSA and agricultural commodities zone maps based on AEZ with scale 1:50.000. The result showed that the wetland paddy is a leading commodity in the study area. Based on comparative and competitive advantages, and compatibility with agricultural commodities zone based on AEZ, wetland paddy is the most leading commodity compared to corn, soybeans and peanuts. It is because of the distribution of this commodity in 10 districts (Sanden, Kretek, Pundong, Bambanglipuro, Pandak, Bantul, Jetis, Banguntapan, Kasihan, and Sedayu) with total area of 11,667 ha or 39.4% of agricultural land in Bantul Regency

Implementation of Integrated Crop Management (ICM) on maize farming in dry land is expected to increase the production and efficiency. This study aimed to: 1) analyze technical, allocative, and economic efficiencies of dry land maize farming under ICM and non-ICM implementation program, 2) identify factors that influence the technical inefficiency of maize farming under ICM and non-ICM implementation program. The study was conducted in maize production center in West Java province at Sukabumi and Garut regencies. Stratified random sampling method was used to survey 300 households in 2015. The data were analyzed using the Cobb-Douglas stochastic frontier production function; while allocative and economic efficiencies were analyzed using the input side approach with frontier dual cost function. The results showed that the productivity of ICM maize farming was 18% higher than the non-ICM. The level of technical, allocative and economic efficiencies of ICM maize farming were 88%, 22%, and 20% respectively, while the level of technical, allocative and economic efficiencies of non-ICM maize farming were 78%, 18%, and 14%, respectively. The level of technical, allocative and economic efficiencies increased by 11% to 30% higher in ICM than the non-ICM. Factors causing technical inefficiency were frequency of extension, educational level, and distance of farmland from farmers residence.

Watershed (DAS) is a complex ecosystem, where land quality is largely determined by land use activities. This illustrates the importance of analytical procedure, especially where the context in which the spatial pattern of land use in the future can be designed based on the risk of degradation in large areas. Data and information are necessary to be used as reference in designing a planning scheme related to land use. Geographic Information Systems (GIS) is a system that has the ability to analyze problems and their spatial and non-spatial combinations (queries) in order to provide solutions to spatial problems. Sustainable farming is an integral part of sustainable development, a farming system which preserves water resources, land resources, and plant resources in acceptable and suitable ways economically, socially, and environmentally. The research aimed to identify and classify critical land by spatial analysis. Based on identification of land, there were 12 individual units in the study area. Based on the spatial analysis, critical land classification was divided into not critical area of 1,818 ha (28.7.%), Potentially Critical 2,596 ha (41.06%), Moderately critical 1,631 ha (25.08%), Critical 226 ha (3.57 %). Most of the land in sub-basin Langge was a hilly area of 1180.6 ha (63.8%) with a slope of 12-25%; 25-40% and above 40%. Alternative farm management in this area was a conservation farm by mechanical conservation techniques (terraces) or vegetative with cultivation techniques hallway, living fences, grass strips and agroforestry.

The availability of water can not be separated from good tertiary irrigation network, apart from the available Secondary and Primary networks and also irrigation dams. Apart from funding, monitoring of JIT (Tertiary Irrigation Network) during the development and implementation is important. Identification of JIT condition is necessary for repairs, and problem frequently arise is the lack of rapid and accurate report from monitoring the condition. A rapid identification method that is simple, fast and accurate, provides an alternative in implementing the irrigation network monitoring. With a simple device that is Android-based mobile phone, equipped with a variety of applications, such as GPS Test, Open camera, GPS Photo Viewer and Photo folders, it is easier in monitoring of JIT. Results of monitoring in West Lombok using rapid method as an alternative, provided an option, better than the old method, with garmin gps, pictures with coordinates that can be sent directly, via social media, so that monitoring can be viewed simultaneously in the field and in the central office, monitoring information did not require a long time in the reports, and impact evaluation could be faster.

Maize is the second basic food need after rice that is potential and has high economic value in increasing income of farmers and food diversification program. White maize, in particular, is an alternative staple food in Grobogan Regency. The superior variety is a component of technology that plays a prominent role to increase productivity, disease resistant, and environmentally suitable (specific location). The aim of the study was to determine the influential factors in the adoption of superior variety of white maize in order to achieve transfer of technology. The study was carried out in three villages of Grobogan Regency, Central Java: namely Sumber Jatipohon, Godan, and Karangasem. The locations were determined with purposive sampling and the number of respondents interviewed was 120 farmers (40 farmers in each village) between September-December 2015. Analyses of the data were descriptively and quantitatively using percentages, charts and tables with logistic regression. The results of this study showed that the interest of farmers to adopt new superior variety of white maize was quite good around 66.7 percent. Farmersâ€™ interest toward superior variety may be considered high. While factors significantly influencing the adoption included income, knowledge or information on technology, agriculture extension support, pest, and availability of seeds. On the other hand, factors which were not significantly affecting the adoption included age, formal education, farmersâ€™ experience, and land size.

One of the problems encountered in the development of sugarcane (Sacharrum officinarum L.) includes the availability of sugarcane seed both in quality and quantity. Evaluation of bud sett planting method in seed production was required in order to achieve the expected results. The study was conducted at the experiment station Muktiharjo, Central Java in 2012 using PSJT 941 varieties. Treatments applied were the different number of buds on bud sett which were at 3 levels, 1 bud, 2 buds or 3 buds. Research was arranged in a randomized complete block design (RCBD) with 5 replications. Observations were conducted on germination, tillering, plant height, number of stems, number of suckers and number of buds. The data obtained were analyzed with ANOVA and further tested using the Duncan test. Production assessment modeling approach was performed by a regression analysis. Calculation of stem number on 2 buds showed the highest with 9.6 stems/m, 9.2 buds/stem and with the sucker numbers lowest at 0.38 suckers/m. The highest production buds was obtained at planting 2 buds with 847,848.06 buds/ha which can be used as 8.83 ha for the milled sugarcane plantation. Assessment of bud production per hectare could use equation Y = 159655,48.e0,171.X with the independent variable of stem numbers per meter with a correlation coefficient of 0,9007 and a standard error of 1,0699.
