Rice acreage estimation is a key aspect to guarantee food security and also important to support government agricultural subsidy system. In this paper, we explored a sophisticated method to improve rice estimation accuracy at county scale and we developed our approach with China Environment Satellite HJ-1A/B data in Hunan Province, a fragmented area with complex rice cropping patterns. Our appr...

This is a status paper on a destructive rice disease –bacterial blight (BB), caused by Xanthomonas oryzae pv. oryzae (Xoo). We review the occurrence and spread of this disease, the taxonomy and classification of the pathogen and strategies for disease management. Studies on pathogen variation have revealed that breeding with single major genes for resistance, may be ineffective due to resistanc...

Irrigation for rice cultivation increases the production of Anopheles gambiae, the main vector of malaria in Mali. Mosquito abundance is highly variable across villages and seasons. We examined whether rice cultivation patterns mapped using remotely sensed imagery can account for some of this variance. We collected entomologic data and mapped land use around 18 villages in the two cropping seas...

Based on image processing technology, the detection, classification and feature extraction for plant grain shape are performed in this paper. Taking rice grain as an example, the shape detection and description method of similar round object are studied firstly. Then a grain shape description method based on 8 feature points of rice grain boundary is proposed. Aiming at rice seed detection, a s...

aerobic rice is as useful potential in reducing of water problem. comparison and investigation of genetic differences between iranian rice varieties and aerobic rice can be useful in identification of genomic regions influencing in drought tolerance. in the present study in addition to an examination of germination genotypes under osmotic stress, allelic diversity were evaluated in 53  genotype...

Sentinel-1A and Landsat 8 images have been combined in this study to map rice fields in urban Shanghai, southeast China, during the 2015 growing season. Rice grown in paddies in this area is characterized by wide inter-field variability in addition to being fragmented by other land-uses. Improving rice classification accuracy requires the use of multi-source and multi-temporal high resolution d...

Functional properties of fermented bran produced by Aspergillus oryzae and Rhizopus sp. in a solid-state fermentation system were determined, with an aim to evaluate their application in food formulation. The defatted rice bran and wheat bran were inoculated with the spores of the cultures and incubated at 30°C for 72 h. Samples were withdrawn at 0, 24, 48 and 72 h. Protein content, protein sol...

In this paper, we present a case study of interpreting paddy distributions of three counties on Northern Taiwan during two crop seasons on year 2000 using multitemporal imageries together with cadastre GIS by Bayesian posteriori probability classifier. In order to integrating Bayesian conditional probability, priori probabilities of paddy's attributes were estimated from photogrammettric interp...

Stabilized rice bran (SRB) is classified as a "functional food" because of its prebiotic characteristics. With increasing grain prices and the pressure to remove antibiotics from swine diets because of concern over antibiotic resistance, SRB was investigated as a nursery diet ingredient with and without the addition of antibiotics (ANT). Two hundred pigs were weaned at 21 d of age, blocked by B...

AIMS This study aimed to determine the effect of a cell-free supernatant of Lactobacillus paracasei ATCC 27092 with and without rice bran extract (RBE) on Salmonella Typhimurium 14028s growth, and to identify a metabolite profile with antimicrobial functions. METHODS AND RESULTS Supernatant was collected from overnight cultures of L. paracasei incubated in the presence (LP+RBE) or absence (LP...
