Estimations of crop area were made based on the temporal profiles of the Enhanced Vegetation Index (EVI) obtained from moderate resolution imaging spectroradiometer (MODIS) images. Evaluation of the ability of the MODIS crop detection algorithm (MCDA) to estimate soybean crop areas was performed for fields in the Mato Grosso state, Brazil. Using the MCDA approach, soybean crop area estimations ...

Rural Realities is published by the Rural Sociological Society, Brigham Young University, 2019 JFSB, Provo, Utah 84602 [email protected] http://www.ruralsociology.org • The farm bill creates dual incentives for both crop production and conservation. Frequently, these two goals pull in opposite directions; subsidies lead farmers to focus on crops that depend heavily on water, contribute to...

Throughout the world there is a strong evidence to support the link between poverty and soil conditions. In subsistence agriculture the wealth of people on low fertility sandy soils is much lower than those living on rich volcanic soils. But there are great differences between regions in the world and this talk focuses on historical developments in soil research in tropical and temperate region...

in order to study the complementary effects of application time of two herbicides sulfosulfuron 75% wg (apyrus) and 75% sulfosulfuron + 5% metsulfuron-methyl (total) and planting wheat density on wild barley (hordeum spontaneum koch.) control, an experiment was conducted in randomized complete blocks design with two-factors during 2012-2013 growing season in zarghan (fars). the first factor was...

This paper has two-fold contribution. First, normality of the crop yield residuals are examined using panel statistical procedures accounting for trend, autocorrelation and heteroskedasticity. Second, to evaluate the importance of accounting for spatial and temporal variation on the normality of crop yield residuals, the changes in the skewness, kurtosis and D’Agostino-Pearson 2 (K ) omnibus no...

This study looked at regulated deficit irrigation (RDI) on leafhoppers in the genus Erythroneura (Erythroneura elegantula Osborn, or western grape leafhopper, and Erythroneura variabilis Beamer) (Hemiptera: Cicadellidae), which are serious pests of cultivated grape (Vitis vinifera L.) in California. RDI is an irrigation strategy that reduces irrigation during a critical point in the phenology o...

Submit Manuscript | http://medcraveonline.com in its theoretical yield (470mt ha-1 year-1) and productivity achieved at field (168 mt ha-1year-1) with average cane yield hovering around 65 tonnes ha-1. In India, which is second largest sugarcane producer in the world after Brazil, this productivity lingers around 28 % of the theoretical maximum. The prevalence of short duration crop cultivation...

Maize and Indian mustard are significant crops in semi-arid climate zones of India. Improved water management requires precise scheduling of irrigation, which in turn requires an accurate computation of daily crop evapotranspiration (ETc). Daily crop evapotranspiration comes as a product of reference evapotranspiration (ET0) and the growth stage specific crop coefficients modified for daily var...

Ground-based remotely sensed data were used in two major approaches to estimate crop coefficient and evapotranspiration (ET) over two treatments of limited-irrigation corn in northeastern Colorado. The first approach, known as the reflectance-based crop coefficient, takes advantage of the unique relationship between crop coefficients (Kc) and vegetation indices of agricultural crops. The second...
