Effects of genotype and simulated rainfall on the morphological characteristics, chemical composition and rumen degradation of the straw fractions of barley plants
Experiments comparing the nutritive value of cereal straws from different genotypes are often complicated by the difference in plant height which is affected by genotype and the amount of rainfall. Two experiments were ...
Production of green feed and grain from grazed barley in Northern Syria
The effects on barley production of variety, seed rate, nitrogen fertilizer rate and timing of grazing were studied in experiments grazed by sheep. The production of green material at the tillering stage and subsequent ...
Grain yield responses of barley and durum wheat to split nitrogen applications under rainfed conditions in a mediterranean environment
Four experiments using split nitrogen applications to barley and durum wheat were grown in northern Syria in 1981/82 and 1982/83. The variables studied were nitrogen rate, ratio of splitting (percent at sowing/percent at ...
Mapping of QTL associated with nitrogen storage and remobilization in barley (Hordeum vulgare L.) leaves
Nitrogen uptake and metabolism are central for vegetative and reproductive plant growth. This is reflected by the fact that nitrogen can be remobilized and reused within a plant, and this process is crucial for yield in ...
Crop evapotranspiration — a technique for calculation of its components by field measurements
A simple technique is described whereby standard field measurements of crop evapotranspiration (ET), evaporation from an uncropped soil (ES), green area index (G), the crop extinction coefficient (K) and above ground dry ...
Molecular mapping as a tool for pre-emptive breeding for resistance to the exotic barley pathogen, Puccinia striiformis f. sp. hordei
Barley stripe rust (BSR), caused by Puccinia striiformis f. sp. hordei, has been a major disease problem to the barley industry worldwide that has not, to date, been detected in Australia. This paper describes the mapping ...
Effects of fertilizer, variety and location on barley production under rainfed conditions in Northern Syria 1. Root and shoot growth
Two varieties of barley, Arabic Abiad (a two-row local landrace) and Beecher (a six-row Californian variety) were grown both with and without fertilizer at two sites with differing rainfall in Aleppo province, Northern ...
