The organization of crop cultivation practices is still far from completion, and Web Resources are not used adequately. This paper proposed a method, based on SVM, to organize the knowledge of crop cultivation practices efficiently from Web Resources. The knowledge organization method of crop cultivation was proposed with Good Agricultural Practices (GAP) in the application of the crop cultivat...

This study assesses the impact of irrigating with desalinated seawater (DSW) on profitability greenhouse tomato in south-eastern Spain, comparing different water-quality sources both traditional sanding cultivation and soilless hydroponic production. The assessment is based combination partial crop budgeting techniques field data from LIFE DESEACROP Project experimental activities. Our results ...
The objective of the present study was to financially compare chemical and agricultural management methods of rice blast disease, as a prevalent disease in paddy fields of Langerood in Guilan Province, Iran. Thirty-three rice experts and 373 paddy farmers were selected by random sampling procedures. Data were collected by a research made questionnaire and were analyzed by SPSS. Benefit Cost Rat...

objective: in recent years, farmers have shown great interest to using native drill planter rather than complex planters to grow vegetables. methods: in this study, we tested a native planter independent variables were the two types of substrate surface (asphalt and plowed field), three ground speed (3, 5 and 7 kph) and four types of seeds (tomatoes, onions, radishes and lettuce). dependent var...
An estimated 260 million indigenous peoples live in Asia. Most of them inhabit forested uplands where a large number of them practice shifting cultivation, which is also called as swidden cultivation or rotational farming. For them, shifting cultivation is not merely a technique of farming; it is their ways of life. Government policies and laws have attempted to limit or outright ban shifting c...
In a spatial thermal gradient, Caenorhabditis elegans migrates toward and then isothermally tracks near its cultivation temperature. A current model for thermotactic behavior involves a thermophilic drive (involving the neurons AFD and AIY) and cryophilic drive (involving the neuron AIZ) that balance at the cultivation temperature. Here, we analyze the movements of individual worms responding t...
Simplified cultivation technologies for rice have become increasingly attractive in recent years in China because of their social, economical and environmental benefits. To date, several simplified cultivation technologies, such as conventional tillage and seedling throwing (CTST), conventional tillage and direct seeding (CTDS), no-tillage and seedling throwing (NTST), no-tillage and direct see...
The mineral contents of the cultivation substrates, fruiting bodies of the mushrooms, and the postharvest cultivation substrates were determined in cultivated edible mushrooms Pleurotus eryngii, Flammulina velutipes, and Hypsizigus marmoreus. The major mineral elements both in the cultivation substrates and in the fruiting bodies were K, Mg, Ca, and Na. Potassium was particularly abundant rangi...
