Water quality in semi-intensive carp production system using three different feeds
(Bulgarian Journal of Agricultural Science, 2010)
In the era of growing demand for sustainable usage of water, all types of aquaculture systems are under reconsideration. Until recently semi-intensive production was concerned to be one of the least polluting. Nowadays, ...
Inbred lines of different cycles of selection - donors of favourable alleles for the improvement of the kernel row number of f-1 maize hybrids
(Turkish Journal of Field Crops, 2012)
Eight maize inbred lines of different cycles of selection, originating from synthetic populations BSSS and BSCB1, were observed in the present study. The aim of the study was to evaluate inbreds and to determine which ones ...
Deficit irrigation based on drought tolerance and root signalling in potatoes and tomatoes
(Elsevier, Amsterdam, 2010)
Agriculture is a big consumer of fresh water in competition with other sectors of the society. Within the EU-project SAFIR new water-saving irrigation strategies were developed based on pot, semi-field and field experiments ...
Composition and stability of soil aggregates in Fluvisols under forest, meadows, and 100 years of conventional tillage
(Wiley-V C H Verlag Gmbh, Weinheim, 2010)
Conversion of meadow and forest ecosystems to agricultural land generally leads to changes in soil structure. This comparative study presents the composition and stability of structural aggregates in humus horizons (0-30 ...
Cross-(in)compatibility in apricot (Prunus armeniaca L.)
(Taylor & Francis Ltd, Abingdon, 2010)
Eight apricot (Prunus armeniaca L.) cultivars and selections were self- and cross-pollinated in order to determine their pollen and stylar compatibility. Overall, 40 pollination combinations were examined. Pollen-tube ...
Broiler breeder age affects carrying eggs intensity, brood eggs incubation values and chicken quality
(Journal of Food, Agriculture and Environment, 2010)
These investigations were attended to identify the influence of parental flock age at heavy hybrid Cobb 500 (usage period) on more important reproductive capabilities, respectively, on carrying eggs intensity of brood eggs, ...
Oilseed rape (Brassica napus L.) genotypic variation in response to boron deficiency
(Tubitak Scientific & Technical Research Council Turkey, Ankara, 2012)
Boron efficiency of 16 oilseed rape genotypes was tested using both hydroponic and pot-soil growing techniques. From the nutrient solution experiment (0.1 and 10 mu M B), 4 representative contrasting genotypes were selected ...
Comparison of tillage systems according to fuel consumption
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
Nowadays, tractor is still the basic power unit in almost all production processes in agriculture, including tillage. The structure of tractor-machinery systems depends on many parameters: seeding system, soil conditions, ...
Seasonal water pricing using meteorological data: case study of Belgrade
(Elsevier Sci Ltd, Oxford, 2012)
The paper presents a model of seasonal water pricing (SWP) aimed primarily at diminishing excessive fresh water use in the city of Belgrade. Seasonal prices are determined on meteorological observations of the average ...
The investigation of phenol removal from aqueous solutions by zeolites as solid adsorbents
(Elsevier, Amsterdam, 2010)
This work reports results on phenol adsorption from aqueous solutions on synthetic BEA (beta) and MFI (ZSM-5) zeolites, studied by heat-flow microcalorimetry. For the sake of comparison, the adsorption was performed on ...
