Field and laboratory experiments were conducted to investigate the weed suppressing effects of cover crops in single mixed cultivation. Weed densities field ranged from 0 267 plants/m2 with Chenopodium album L., Matricaria chamomilla Stellaria media (L.) Vill. as predominant weeds. It was found that mustard (Sinapis alba L.), fodder radish (Raphanus sativus var. niger J. Kern) spring vetch (Vicia sativa L.) supressed weeds by 60% crop mixtures controlled 66% during fallow period at three...
Summary Cover crops can suppress weeds within agricultural fields due to competitive and allelopathic effects. Glasshouse experiments were conducted evaluate the relative proportions of effects total weed inhibition. Six different cover crop species combined with three in presence or absence active carbon over a period four weeks. Active was used as an adsorbent for substances soil. Our study revealed that competition between shifted, possibly minimisation by We assume degree on is...
Reducing the use of chemical-synthetic herbicides with site-specific application technology will play an important role in agricultural research and practice coming years decades. This paper presents a sprayer for weed control row crops using detection based on image analysis spot data. Two small plot trials sugar beet maize 2021 seven On-farm field beet, sunflower 2022 are presented. A pair-wise comparison broadcast application, untreated spotting were realized. zero-tolerance strategy...
The water demand for cover crops (CC) should be considered to achieve competitive crop stands weed control also under unfavorable conditions. This study aims estimate the suppressive ability of winter CC, as Sinapis alba L., Phacelia tanacetifolia Benth., Vicia sativa L. and Avena strigosa Schreb., a water-limited regime. deficit tolerance different CC was determined in greenhouse experiment by measuring maximum quantum efficiency photosystem II. Moreover, soil moisture, establishment were...
Field experiments were conducted at two locations in 2014-2015 and 2015-2016 to investigate the weed suppressive ability of cover crop mulches sugar beets. Three crops mixtures tested all four experiments. Weed densities ranged from 2 up 210 plants/m2 Chenopodium album L. Stellaria media (L.) Vill. as predominant species. Sinapis alba grew significantly faster than Vicia sativa, Raphanus sativus var. niger, both mixtures. alba, niger reduced density by 57, 22, 15% across locations,...
The weed suppressive ability of oilseed radish (Raphanus sativus var. oleiformis Pers.) cover crop is attributed to high competitiveness for resources and biochemical effects on weeds. was sown in five treatments plus an untreated control over a period weeks before three after winter wheat harvest. Additionally, fertilization biomass suppression were measured. highest the observed 12 harvest (WAH) when one week (1 WAH) (2015) (5 WBH) (2016). No differences concerning 2015, whereby increased...
Weed suppression of cover crops is a result competition for light, space, water and nutrients the release allelochemicals in soil.
