PRODUCTION, ECONOMIC AND ENERGY EFFECTIVENESS OF WINTER BARLEY CROPPING AT VARIOUS RATES OF NITROGEN FERTILISATION
winter barley production and economic effectiveness nitrogen fertilisation
2009/3/30
Nitrogen fertilisation is one of the most effective yield-increasing factors but also one of the most critical items of cereal production costs. The aim of the present study was an attempt at definin...
Indigenous soil nutrient supply and effects of fertilizer application on yield, N, P and K uptake, recovery and use efficiency of barley in three soils of Teghane, the Northern highlands of Ethiopia
Agronomic efficiency internal nutrient use efficiency maximum accumulation maximum dilution
2009/3/4
So far, application of fertilizer to mitigate problems of nutrient-limited yields in farmers’ fields in the Highlands of Ethiopia has been based on conventional blanket fertilizer recommendation...
Effect of soil compaction on growth of narrow-leafed lupine, oilseed rape and spring barley on sandy loam soil
soil compaction lupine oilseed rape spring barley bulk density penetration resistance
2010/1/15
Soil compaction is an environmental problem and has been recognized as the main form of soil degradation in Europe. Soil compaction may increase soil strength and compacted soil layers can affect root...
Effect of Potassium Rates on Barley Growth and its Mineral Content under Different Salt Affected Soil Conditions
Saline Sodic Saline sodic soil potassium rates barley growth parameters mineral content
2010/11/9
Ca and Mg uptake by starw and grains of barley plants grown on all the used soils, showed the same trend as affected by K rates under different soils. The highest levels of both

Ammonia volatilization, nitrogen in soil, and growth of barley after application of peat manure and pig slurry
nitrogen ammonia volatilization animal manures slurries peat barley
2010/8/10
Peat is added to manure, because its low pH and capacity to adsorb ammonia (NH3) give it potential to reduce nitrogen (N) loss. Peat manure was prepared by mixing pig slurry with moderately humified S...
Decision support system for agricultural land use and fertilisation optimisation: a case study on barley production in Estonia
barley fertilisation geographical information system land use decision making risk factors soil map
2010/8/10
The success of the decision support systems, developed within GIS with application of different models, depends on the quality of initial data and the models themselves as well as on the possibilities...
