The fight against weeds in the organic cultivation of herbal plants, both raw and for seeds, is a big challenge for growers. The paper compares the chemical (bentazon, 960 g·ha–1 and fluazifop-P-butyl, 150 g·ha–1) and nonchemical (scattering mustard seed meal in two doses 1.5 and 3.0 t·ha–1) control of weeds in the cultivation of lemon balm for seeds. Additionally, the influence of these factors on...
Peppermint (Mentha ×piperita L.) rootstock cuttings with 9–11 internodes were planted on April 10, 2014 in rows 50 cm apart and with 25-cm distance in the row, on well fertilized muck-peat soil containing 82.1% of organic matter with a pH of 5.9. Peppermint plants were sprayed once with an activated EM-1 preparation, then on two or three further occasions as follows: at 10 cm height (May 10), at branching...
Globally, the application of rootstocks for grapevine cultivation has been a standard, while in the northern regions, like in Poland where the viticulture tradition is relatively short, the selection of the most suitable rootstock types requires multi-year observation and research. The objective of the present study was to assess the effect of six following rootstock types: ‘101-14 Mgt’, ‘161-49C’,...
Sour cherry is one of the most important fruit crops in Poland and cultivar is an important factor in its cultivation. The experiment was conducted in a commercial family orchard in a year characterized by a warm and wet spring and also by a very hot and dry summer. Fruit yields harvested from well fertilized 19-years old ‘Kelleris 16’, ‘Nefris’ and ‘Łutówka’ trees grafted on Mahaleb cherry and protected...
Recently the interest in borage as a vegetable and medicinal plant has increased, yet the knowledge about a content of biologically active compounds in borage grown in Poland remains very scanty. In the experiment carried out in the south-eastern part of the country, fresh borage flowers and leaves contained 0.02% and 0.12% of lipids with the highest level of palmitic acid, i.e. 44.5% and 33.4%, respectively...
In a two-year field experiment, no-tillage cultivation using white mustard (Sinapis alba L. ‘Bardena’), 30 kg ha−1, as a cover crop did not influence emergence of red beet (Beta vulgaris L. ‘Czerwona Kula REW’) and had a favorable effect on emergence of carrot (Daucus carota L. ‘Berlikumer 2 – Perfekcja REW’). However, further growth of both vegetables was significantly slower under no-tillage cultivation...
A two years’ field study was conducted to compare the influence of perennial ryegrass (Lolium perenne L.), white clover (Trifolium repens L.), perennial ryegrass + white clover mixture and mowed weeds used as living mulches with the influence of linuron 675 g·ha-1 on weed infestation and yield of carrot (Daucus carota L.) ‘Flakkese 2’ under ridge cultivation. Living mulches did not affect growth of...
No-tillage cultivation using cover crops is an important part of sustainable horticulture, however there are only few date on this subject related to ‘Hamburg’ parsley. In two years` field experiment no-tillage cultivation using white mustard as a cover crop did not affect germination of ‘Hamburg’ parsley cv. Alba but further growth of no-tilled plants was slower. Yield of no-tilled plants with leaves...
No-tillage cultivation with living mulch offers several benefits related to environmental protection and fulfills requirements of sustainable agriculture very well, however there are only few reports on vegetable cultivation using this method and referring to natural conditions of Poland. In three years field experiment stake tomatoes cv. Malinowy Ożarowski grown on no-tilled plots covered with wintering...
