Drought induced stress is one of the most significant environmental challenges. This study was designed to evaluate the effects of drought stress on crop yield and antioxidant systems during the vegetative period of wheat. The study was carried out in a greenhouse using factorial experiment based on complete randomized block design (RCBD) in three replications in Razi University in Iran from 20...

Coppice can provide a cheap alternative to replanting in the second rotation in Eucalyptus globulus Labill. plantations. However, replanting with genetically improved stock may provide a more profitable alternative. A discounted cash flow model was used to compare the profitablity of coppice and seedling crops in second rotation E. globulus pulpwood plantations, using incremental net present va...

PROBA-V is a new global vegetation monitoring satellite launched in the second quarter of 2013 that provides data with a 100 m to 1 km spatial resolution and a daily to 10-day temporal resolution in the visible and near infrared (VNIR) bands. A major mission of the PROBA-V satellite is global agriculture monitoring, in which the accuracy of crop mapping plays a key role. In countries such as Ch...

A recurrent issue for data integration is the lack of a common and structured vocabulary used by different parties to describe their data sets. The Crop Ontology (www.cropontology.org) project aims to provide a central place where the crop community can gather to generate such standardized vocabularies and structure them into ontologies. Having standardized ontologies opens the world of the Sem...

Aflatoxin contamination of food and livestock feed results in significant annual crop losses internationally. Aspergillus flavus is the major fungus responsible for this loss. Additionally, A. flavus is the second leading cause of aspergillosis in immunocompromised human patients. Here, we report the genome sequence of strain NRRL 3357.

background and objectives: seedy watermelon (citrullus lanatus) is a crop that is planted in as a second crop after winter crops some parts of country. this crop is more attended by farmers due to the short time between planting and maturity, low production costs and greater profitability rather than other spring crops. in order to evaluate the interaction effects between weeds and seed priming...

Robotic harvesting of crops has the potential to disrupt current agricultural practices. A key element to enabling robotic harvesting is to safely remove the crop from the plant which often involves locating and cutting the peduncle, the part of the crop that attaches it to the main stem of the plant. In this paper we present a comparative study of two methods for performing peduncle detection....

Leaching losses of N are a major limitation of crop production on permeable soils and under heavy rainfalls as in the humid tropics. We established a field trial in the central Amazon (near Manaus, Brazil) in order to study the influence of charcoal and compost on the retention of N. Fifteen months after organic-matter admixing (0–0.1 m soil depth), we added 15N-labeled (NH4)2SO4 (27.5 kg N ha–...

fajr (ksc 260) is an early maturity grain maize hybrid that has been developed from a cross between two inbred lines (k1264/5-1×k615/1). this cross was carried out in 1998, for the first time. several characteristics of fajr hybrid were studied in different trials (preliminary, semi final, final and on-farm trails) over several locations during 1998 to 2005. the mean grain yield of the hybrid o...
