In this paper, we developed a more sophisticated method for detection and estimation of mixed paddy rice agriculture from Moderate Resolution Imaging Spectroradiometer (MODIS) satellite data. Previous research demonstrated thatMODIS data can be used tomap paddy rice fields and to distinguish rice from other crops at large, continental scaleswith combined Enhanced Vegetation Index (EVI) and Land...

The fundamental discoveries of Darwin and Mendel established the scientific basis for plant breeding and genetics at the turn of the 20th century. Similarly, the recent integration of advances in biotechnology, genomic research, and molecular marker applications with conventional plant breeding practices has created the foundation for molecular plant breeding, an interdisciplinary science that ...

Information on rice crop phenology is important for crop management. This study aimed to detect rice crop phenology in the Vietnamese Mekong Delta using time-series MODIS data in 2007. Data processing steps included: (1) constructing time-series MODIS NDVI data, (2) filtering noise from the time-series data using empirical mode decomposition (EMD) and wavelet transform, (3) detecting rice crop ...

The debate on the relative benefits of conventional and organic farming systems has in recent time gained significant interest. So far, global agricultural development has focused on increased productivity rather than on a holistic natural resource management for food security. Thus, developing more sustainable farming practices on a large scale is of utmost importance. However, information con...

The recent multi-year droughts in California have highlighted the heightened risk of longer and more intense droughts, thus increasing interest understanding potential impacts for major economic activities, such as agriculture. This study examines changes cropping pattern California’s Central Valley between 2007 2016 response to two consecutive (2007–2009 2012–2016), factors driving these chang...

The experimental studies were conducted in 2007-2008, 2008-2009 and 2009-2010 crop seasons, in order to know the agro-economic yield of 'Chinês' and "Macaquinho" taro clones, propagated using huge, extra, large, medium, small and tiny cormels. The harvest was done on average on 202 days after planting, in three crop seasons. Based on the joint analysis of variance carried out, it was observed t...

this research aims at determining and evaluating the water productivity indexes in astan-ghods-razavi companies for different crops during 2007-2008 growth season. required field data were collected during several field surveys. these data consisted of crop yields and crop consumptive water that is irrigated by distinct agriculture well. with regard to collected data, four water productivity in...

A 3- years (2015, 2016 and 2017) field study was carried out at National Wheat Research Program, Bhirahawa, Rupandehi, Nepal to evaluate the influence of crop residues and nitrogen levels on rice. The experiment was conducted in split plot design with three replications. Main plots were two crop residue levels (with crop residues of 30 cm wheat stubble and without crop residues) and sub plots c...
