The aim of the present research was to compare the influence of four cover crops plants and six undersown crop cultivars cultivated on light soil in the Lublin region. The field research was carried out in the years 1993-96 at the Experimental Station of Bezek near Chelm (Poland). The static field experiment was carried out by split-plot method in four replications. The field experiment includ ...

In the experiment weed infestation in specialized crop rotations (with increased percentage of cereal crops) and monocultures of those crops was assessed. The studies included the fifth cycle of four-course crop rotation: 1) potato + -oats-pea-winter rye, 2) potato + -oats-winter rye, 3) potato + -winter rye, 4) oats-winter rye, 5) monoculture of winter rye. Before harvest assessment of weed i ...

The aim of the experiment was to analyse the effect of some intercrop plant species on the yielding and grain quality of spring barley in four-years's monoculture. Seed dressing and harrowing as well as herbicides, fungicides, insecticides and growth regulators were applied in crop protection. The sowing rate for both forms of barley amounted to 300 grains per one square meter. Cultivation of ...

The research defined energy inputs involved in organic (farmyard manure, total plant biomass and postharvest residue of undersown catch crop) and mineral fertilizers (400, 600 kg NPK/ha). There were estimated energy value of feed undersown-catch-crop yield, of sugar beet root and leaf yield and energy effectiveness index. The highest energy inputs were observed in the combination fertilized wi ...

The objective of studies was to determine suitability of lentil and chickling vetch intercropping with wheat, triticale, oats and barley and the effect of spring cereal crops on intercropping with these leguminous crops and also to know the answer whether bringing leguminous into stand of cereal crops is able to substitute nitrogen fertilization or improve its effectiveness. Applying cereal so ...

The aim of this research was to calculate sulphur and nitrogen balance for the four crops grown in four-course rotation in the two-factorial experiment during 1996-99. The sulphur and nitrogen concentrations in crop products, yield and sulphur uptake (per yield unit and total) were measured. The highest values of sulphur deficit was observed for crops with high sulphur demands, like rape and m ...

The research was carried out to determine the influence of differentiated tillage and postharvest management of straw on soil water content and yielding of plants. The experimental factors were: I - different modes of tillage: A - traditional ploughing, B - zero-tillage, weed control with herbicides, direct drilling. II - 5-modes of straw management. The yielding of crops was differentiated, w ...

A research into the influence of conserving tillage technologies on yielding of cereal crops and physical soil properties was carried out in 2003-05. In the field experiment three tillage systems were compared: traditional with post-harvest leaving the straw in form of chaff with ploughing to 25-30 cm depth, simplified with post-harvest leaving the chaff, cultivated to 15 cm depth, direct sowi ...

The objective of this study was to determine the comparative effects of four tillage systems on productivity of crops in crop rotation: peas, winter wheat, spring barley, winter triticale. The main grain yield of spring barley was greater under conventional tillage than either reduced tillage and direct drilling by 6.9 and 12.7 percent, respectively. Direct drilling led to decreased crude prot ...

The study aimed to assess the influence of organic, integrated and conventional crop production systems on weed flora diversity. The study was conducted in the long-term trial, where different crop production systems has been compared since 1994. The analysis of weed diversity was conducted on the fields of all crops cultivated in studied crop production systems, based on weed species composit ...
