The aim of this study was to clarify the distribution irrigated drylands in arid and semi-arid areas, where complex terrain, diverse crops staggered cultivated lands exist. This paper studied classification methods based on temperature, precipitation, Normalized Difference Vegetation Index (NDVI) Water (NDWI) from Landsat data one-harvest area northern Loess Plateau China by using Google Earth ...

This study spatially assesses, quantifies, and visualizes the agricultural expansion and land use intensification in the northwestern foothills of Mount Kenya over the last 30 years: processes triggered by population growth, and, more recently, by large-scale commercial investments. We made use of Google Earth Engine to access the USGS Landsat data archive and to generate cloud-free seasonal co...

Grass pea (Lathyrus sativus L.) has a high potential for forage production inboth rangelands and cultivated rainfed areas of Iran. It is well adapted to semi-arid areas ofwest and north of country where annual rainfall is 250–350 mm. To study the seed and DryMatter (DM) yield and agronomic traits, six genotypes of Lathyrus sativus L. and twogenotypes of Lathyrus inconspicuous L. were provided b...

Changes in soil physical and chemical properties were evaluated in several on-farm studies located in rainfed, hardsetting red Al®sols (Ferric Luvisols) and in irrigated, self-mulching Vertisols (Chromic Vertisols) of eastern Australia. The objective of the studies was to evaluate changes in soil physical and chemical properties with time under commercial farming situations where changes had be...

Agricultural crop species represent a negligible part of the existing biodiversity. Over 50 percent of the daily global requirement of proteins and calories is met by just three crops – maize, wheat and rice (FAO, 1996) – and only 150 crops are commercialised on a significant global scale. On the other hand, ethnobotanic surveys indicate that, worldwide, more than 7,000 plant species are cultiv...

The purposeof this studywas to Analyzing factors that effecting on rangeland degradation. Statistical population of this research consisted of whole farmer in Pirtaj district (N= 1600); from that 120 farmer were selected as sample using cluster sampling. The main tool to collect data was a researcher made questionnaire that Content validity of the questionnaire was approved, by a panel of exper...
