With the availability of required inputs for intensive agriculture, the cropping system in Punjab state has undergone a paradigm shift, from a much diversified cropping pattern to a very specialized monocropped one. A study was undertaken in Bathinda district of Punjab State for mapping crop area, cropping pattern and finally long term changes in cropping pattern. Multi-year, multi-date, IRS LI...
A scientific definition of the type of mountain area and an exploration of the spatial correlation between different types of mountain areas and regional land use at the county level are important for reasonable land resource utilization and regional sustainable development. Here, a geographic information system was used to analyze digital elevation model data and to define the extent of mounta...
Despite the apparent abundance of land, agricultural land with a dependable growing period represents a fraction of the total land area in Ethiopia. Moreover, land degradation is extensive and severe, particularly in the highlands above 1500 meters above sea level, which account for about 40 percent of the total land area but home for 90 percent of the total population and 70 percent of livesto...
The efficient use of water resources, soil, and climate parameters as the main pillars of plant sustainable production requires land suitability evaluation for each crop and area. This research was conducted to evaluate land suitability for walnut cultivation in Iran using geographic information system (GIS). For this purpose, the climate data obtained from 375 synoptic stations of Iran, the ge...
China is the largest cotton-producer in the World with about 4.5 million tons of lint produced annually, which accounts for over 20% of the World’s total production (Xia et al. 2001). Damage from pests is one of the major limiting factors for cotton production in China, among which cotton bollworm (Helicoverpa armigera Hübner) is a key one (Fang et al. 1992). In the early 1990s, due to the dram...
Agricultural expansion is one of the prime driving forces of global land cover change. Despite the increasing attention to the factors that cause it, the patterns and processes associated with indigenous cultivation systems are not well understood. This study analyzes agricultural change associated with subsistence-based indigenous production systems in the lower Pastaza River Basin in the Ecua...
regard to increasing demand for organic agricultural products, awareness of costs and profitability of organic products can help to decision planners of agricultural sector, and particularly farmers. this study has tried to calculate cost and profitability of cotton product in two different conventional and organic ways (procedure) of production using 253 cross-sectional data from khorasan raza...
ABSTRACT- Crop rotation has many benefits for agro-ecosystems production. In order to evaluate two current rotation systems of wheat (Triticum aestivum L.) production in Kamalabad region of Fasa, an experiment was conducted during 2015-2016 growing season. The rotation systems were fallow-wheat and cotton (Gossypium spp.)-wheat. Research plots were arranged as a randomized complete block design...
Farmers’ awareness of beneficial and harmful effects of pesticides and factors determining use of pesticides were analyzed using survey data from 21 villages in three agro-ecological regions of Bangladesh. Pesticide cost accounts for about 7.7 percent of the gross value of output in cotton, 3.6 percent in vegetables, 2.5 percent in potato, 1.8 percent in modern rice, 1.6 percent in spices and l...
