We present the effects of cytoplasm substitution on five productivity traits in an alloplasmic barley collection. 60 lines combining 5 nuclear genomes of cultivated barley varieties and 12 plasmons of two barley species (H. vulgare, H. spontaneum) displayed various effects depending on definite nuclei-cytoplasm combinations. Only four cytoplasmic genomes (W1, W4, W5, W10) significantly modified...

low cereal and legumes yields and their rwp index are mainly due to poor distribution of rainfall and poor agronomic management practices. rainfed barley yield and rain water productivity (rwp, defined as rainfed grain yield divided by the total crop season annual rainfall water) in the dry farming are considerable by topography and latitude. yield data, rainfall, altitude and latitude of 182 p...

the main objective in production of any rainfed crop, including barley farming is to increase water productivity along with stability in the production of the rainfed crop through improvement of the agronomic management including limited single irrigation (si) and sowing date (sd). in order to determine optimal si management and limited water allocation scenarios, a field experiment was conduct...

background and objectivesintercropping or simultaneous growing of two or more crops on the same piece of land has the potential of enhanced ecosystem productivity. in a cereal-legume intercropping system, an increase in cereal and a decrease in legume intercrop yield is reported. several indices such as land equivalent ratio (ler), relative crowding coefficient (k), competitive ratio (cr), aggr...

comparison of energy productivity of different crops can be used as an effective tool to prioritize crops planting in each area. this study was conducted in order to compare of wheat and barley farms of sistan and blochestan province in relation of various aspects of energy consumption at 2009. 100 wheat and 100 barley fields were selected randomly from zahedan, zabol, saravan, khash, iranshahr...

Penicillium canescens 10-10c strain was cultivated on barley straw hydrolysate as a soluble nutrient source and as inducer for xylanase production. Barley straw hydrolysate was obtained by treatment of barley straw with NaOH or hot water. In shake flask cultures, NaOH treatment was found to increase the biomass production, but was not accompanied by an increase in xylanase production. The best ...

Extensive application of imidazolinone (IMI) herbicides had a significant impact on barley productivity contributing to a continuous decline in its acreage over the last two decades. A possible solution to this problem is to transfer IMI-resistance from a recently characterized mutation in the 'Bob' barley AHAS (acetohydroxy acid synthase) gene to other food, feed and malting barley cultivars. ...

Minnesota’s crop economy, which totaled more than $12.7 billion in 2009, depends largely on corn and soybeans. However, a variety of other crops, including wheat, sugar beets, dry beans, alfalfa, sunflower, potatoes, oats, and barley, are also frequently grown in Minnesota. All of these crops are important in Minnesota in large part because its climate is conducive to their growth. The term cli...

Wheat and barley are the main crops in Iran and has multiple uses. Research suggests that subsistence food crops such as wheat and barley has a special place in low-income countries. However, to achieve maximum efficiency for a sustainable agriculture must be able to obtain agricultural inputs such as land. Kerman province is one of the provinces with high production of these products. Accordin...
