Abstract :

The aim of this research was estimation of weeds infestation of winter rye, cultivated in crop rotation and multispecific monoculture of cereal crops in conditions of high and low levels of agricultural production intensity on typical rye soils. Cultivation of winter rye in the crop rotations significantly decreased weed infestation as compared to the cereal crops monoculture. The lowest infes ...

Abstract :

The study was conducted in four-field rotation: potato -spring wheat - peas - winter wheat in 1999-02. Three tillage systems: plough-simplified, and ploughless - and two mineral fertilization levels: medium-high (average of 127 kg NPK/ha) on annual basis - and increased by 50 percent). Energy-efficiency indicators were found to depend more on the species rather than on level of tillage simplif ...

Abstract :

The effect of three tillage systems on the crop yield in rotation was compared in the experiment in 1997-99, which is a continuation of earlier researches. The field experiment was conducted on the medium heavy rendzina, which belongs to a defective wheat soil complex. In the 2-nd rotation the grain yield of all plants decreased independently of the tillage system. In case of horse bean it was ...

Abstract :

A static field experiment was conducted to study the effects of winter rye growing in the 25th, 26th and 27th year in 2 crop rotations with 100 percent of cereals (rye and stubble crop - spring barley - oats; rye and catch - rye) using 2 fertilizer rates on its yielding and on selected soil properties. Rye as a control treatment was grown in a 4-crop rotation: potato - oats - field pea - rye a ...

Abstract :

The influence of three types of soil cultivation regimes (traditional tillage, no tillage and direct sowing) on weed communities developing among crops in three-fields rotation system: horse bean - winter wheat - spring barley was analysed in the statical field experiment. Using the Sorensen formula the weed communities' similarity ratios were calculated. Variance analysis was used for results ...

Abstract :

The effect of land use on fertilizer elements losses with surface runoff was studied in a mountain region in Southern Poland in 2003-04. Runoffs were collected from 7 intensively fertilized uses and unfertilized fallow localized on a slope with 16 percent gradient. The plants were cultivated in rotation (see above). N, P and K concentrations in surface runoffs depended on amount, intensity and ...

Abstract :

The aim of the paper is comparison of yielding of pure stands and two-element mixtures containing spring barley and morever to determine the influence of yielding constituents on a differentiation of spring barley yields according to the other mixture components. Among pure stands and mixtures the greatest yield was obtained in case of spring barley monoculture. For barley grown in mixtures, o ...

Abstract :

The aim of the paper was the comparison of carbon and nitrogen accumulation possibilities in soil layers 0-10 and 10-20 cm depending on: 50-year mineral, organic and mineral-organic fertilization, 30-year mouldboard ploughing and no-tillage (direct sowing). The bases of the research were two long-term field experiments located on a black soil developed from boulder loam. In the first experimen ...

Abstract :

The field study was carried out in 2003-2005 based on static experiment laid out in 1999 on the soils classified as Albic Luvisols developed on loamy sands overlying loamy materials. The objective of this study was to determine the comparative effects of three tillage systems: conventional ploughing, reduced tillage with shallow stubble cultivator and direct drilling on some physicochemical so ...

Abstract :

The studies on physico-chemical soil properties dependent on tillage system were conducted in 2004-06. The purpose of the study was to determine the effect of some soil tillage systems on physical and chemical soil properties in comparison to both successive and cut fallow soils. After four years after differentiation of soil tillage systems no explicit changes of physical and chemical soil pr ...
