The Mediterranean climate region on the west coast of the United States is characterized by wet winters and dry summers, and by high fire activity. The importance of synoptic-scale circulation patterns (ENSO, PDO, PNA) on fire-climate interactions is evident in contemporary fire data sets and in pre-Euroamerican tree-ring-based fire records. We investigated how interannual variability in two fi...

Salinity is one of a major abiotic stress, specifically on arid and semi-arid areas that has influenced on crop growth and reduced grain yield. The purpose of present study was identification of agronomic traits related to wheat grain yield variation under control and salinity conditions. In order to produce a population of 272 recombinant inbred lines (RILs), a cross between two bread wheat cu...

This research was conducted to determine the effect of corn genetics and cutting height on the composition and nutritive characteristics of corn silage. An in situ study involving eight commercially available corn hybrids indicated main effects and interactions (P < 0.01) of hybrid and cutting height on NDF, ADF, and starch content and on in situ DM and NDF degradablility. Four ruminally cannul...

drought stress is one of the most important abiotic stresses which can affect the growth of a plant, thereby curbing crop yield. identification of effective morphological traits is the main aim of each breeding program. our objective was to identify agronomic traits associated with changes in grain yield of wheat under irrigated and drought conditions. to address this objective, grain yield and...

This experiment was carried out at the Agricultural Research Station of Bu-Ali Sina University to study the effect of different tillage methods on bulk density, yield, and yield components of barley (Hordeum vulgare) cultivars under rainfed conditions. Three levels of tillage (CT: conventional tillage, MT: minimum tillage and NT: no tillage) and five barely cultivars (V1: Local V2: AbidarV3: ...

We examined the occurrence of brown bear (Ursus arctos) in Finland by using hunterprovided observations and harvest data for 1992–2004. We calculated a simple index (bears observed/ all observation cards) from observation cards filled annually by nearly 5,000 moose hunting clubs. This occurrence index was treated as a dependent variable in a mixed regression model to examine differences between...

the effects of plant densities (25, 35 and 45 plants m-2 as d1, d2 and d3 respectively), and inoculation with rhizobium bacteria (without rhizobium, with rhizobium and rhizobium + microelement application), on growth and yield were studied in chickpea (cicer arietinum l.). experiment was carried out in 2008 at research farm of the faculty of agriculture of university of mohaghegh ardabil, a fac...

Correct timing of fruit harvest may lead to increase in production efficiency, decrease in transportation and storage costs and prevent loss of quality. A 3-replicate factorial experiment based on a completely randomized design was conducted in order to investigate the effect of harvest time and storage on qualitative properties of red grape, the variety of Fakhri shahroud. Sampling was done in...
