Abstract

The production areas of food crops reported fluctuating during 2005 to 2009 reported by Mitra Usaha Tani. The datas showed that the production areas of rice was decresed. In contrast, its corn, cassava and sweet potato were decreased. It is necessary to increase the food production area through government policy. Analysis of land suitability for crops with a Geographic Information System (GIS) is one of the basic for policy-making and the development of technical suggestions in the agricultural sector. This research used grid-type survey method. In this case, the soil properties compared to the factor class of land suitability for particular plant based on modifi ed of FAO 1976) and Sys et. al. (1993) according to the local conditions of Madiun. The aim of this research was to evaluate the land in Madiun. It could be recomand to increase the production area of rice, corn, peanuts, bean, soybean, cassava and sweet potato. The result showed that land suitability for areas of rice production was 41.347 ha, corn 42.909 ha, peanut 41.547 ha, bean 42.909 ha, soybean 41.927 ha, cassava 41.537 ha, and sweet potato 41.537 ha.

Abstract

A survey of phytopathogenic fungi and Oomyceteswas conducted in Riyadh, Kingdom of Saudi Arabia duringOctober 2008 – May 2009. Total of 223 samples were collectedfrom four regions; Al-Kharj, Oyaynah, Old Diriyah, and Al Amariyah. Isolation was done using Potato Dextrose Agar(PDA). Infected parts were cut then sterilized in chlorox(10%), then were put in petridish that contain PDA andincubated at 25-27 °C. A total twelve genera of fungi andsingle genera of Oomycetes were isolated from the infectedplants and identifi ed as Fusarium spp., Alternaria spp.,Helmintosphorium (Bipolaris) spp., Sclerotium spp., Rhizoctoniaspp., Cladosporium spp., Mauginiella scattae, Erysiphe spp.,Leveillula spp., Macrophomina phaseolina, Ustilago spp.,Ulocladium spp., and Phytium spp.

Abstract

The aim of this experiment was to study the effectof pine leaf as allelophaty on purslane germination. Theexperiment were conducted at screen house Departmentof Biology, Faculty of Mathematics and Science, BrawijayaUniversity. The research is experimental design by nonfactorial Completely Randomized Blok Design, with threereplications, consisted of eleven levels. Purslane seeds sprout with control treatment, signifi cantly different from seedssprout ability in treatment solution leaves Pinus merkusii 2000ppm, and solution leaves of P. longaeva 2000 ppm. The resultshowed that 2000 ppm of P. merkusii extraction signifi cantlysuppressed 46% of purslane germination whereas 2000 ppmPinus longeava extraction signifi cantly suppressed of 41%campared to without any treatments (control).

Abstract

Kepok Kuning banana (Musa acuminate × M.balbisiana) is a banana which has a good adaptability tothe water shortage conditions. The banana has cultivatedin watershed of Tajum river, Banyumas. The place haspotential to be centre of Yellow Kepok banana productionbut the farmers occasionally applied fertilizer unbalancedwhich effect to productivity and quality of banana. It isnecessary to examine proportion of fertilizers to determinethe effective and effi cient fertilizer composition whichincreased productivity and quality of banana.The experiment was conducted on Gentawangi dryland farm, Jatilawang, Banyumas on January-June 2009. Theexperiment was laid out in randomized block design with12 replications and involving single factor. It consistedof 5 treatments The Banana was planted in pattern 3 m x3 m. Results showed that banana required both of organicfertilizers and inorganic in vegetative stage. The treatmentof Urea 150 g + 100 g + SP36 compost 10 kg/tree/applicationshowed the effi cient compared to other, followed bytreatment of ZA 150 g + SP36 KCl 150 g + 50 g/tree/application. Combination of Urea and ZA without organicfertilizer indicated uneffi cient compared to others

Abstract

The importance of organic fertilizers in a cropcultivation is to restore land productivity and reduce the useof synthetic fertilizers. Various ways has been developed tocreate quality organic fertilizer, for plants vegetables suchas red chili, shallots and leek with low input. The aims ofthis study were to determine the effect of some kind of solidorganic fertilizer on the growth and yield of red chili, shallots and leek, and to know the best organic fertilizer for each typeplants. The experimental design used is Split Plot Designwith the basic design of Randomized Complete DesignBlockwith 3 replications as blocks. The main plots consistedof 3 species of plant vegetables. The subplot consisted of 5kinds of solid organic fertilizer and without any treatmentsas control. There were 18 plots per block or the totals were54 plots. The results showed that aplication of several typesof solid organic fertilizer signifi cantly increased the growthand yield of red chilli, shallot and leek. Solid organic fertilizerfrom community A showed that the highest signifi cantlyincreased the growth and yield of red chilli. Combinationof organic fertilizer and Rock Phosphate (RP) 2.4 ton / hashowed the highest growth and yield of leek. Combinationof organic fertilizer and K-feldspar 0.6 ton / ha showed thehighest growth and yield of shallot
