“…Stale seedbed techniques can be employed to reduce weed populations prior to planting in many conservation tillage systems [20], but this approach is not feasible in organic ZT systems [103]. However, there are weed management strategies in addition to the use of cover crops that could be incorporated into organic ZT for weed control.…”

Abstract:Organic farming has been identified as promoting soil quality even though tillage is used for weed suppression. Adopting zero tillage and other conservation tillage practices can enhance soil quality in cropping systems where synthetic agri-chemicals are relied on for crop nutrition and weed control. Attempts have been made to eliminate tillage completely when growing several field crops organically. Vegetative mulch produced by killed cover crops in organic zero tillage systems can suppress annual weeds, but large amounts are needed for adequate early season weed control. Established perennial weeds are not controlled by cover crop mulch. Integrated weed management strategies that include other cultural as well as biological and mechanical controls have potential and need to be incorporated into organic zero tillage research efforts. Market crop performance in organic zero tillage systems has been mixed because of weed, nutrient cycling, and other problems that still must be solved. Soil quality benefits have been demonstrated in comparisons between organic conservation tillage and inversion tillage systems, but studies that include zero tillage treatments are lacking. Research is needed which identifies agronomic strategies for optimum market crop performance, acceptable levels of weed suppression, and soil quality benefits following adoption of organic zero tillage.

“…Do tree shelters enhance growth, photosynthesis and photo-chemical response of weeding treatments in seedlings? Some authors considered that a more comprehensive management of vegetation systems requires knowledge of new techniques and/or methods to combine multiple techniques (Kurstjens 2007). Our study focused on assessing the morpho-physiological response of Holm oak plantations to weed control and individual protection as a combined cultural technique.…”

“…Fatal germination is an important factor of weed seed mortality (Schwinghamer & Van Acker 2008), and its frequency may be increased by tillage (Kurstjens 2007), which has valuable effects on decreasing seed survival in the soil (Gruber & Claupein 2006;Gruber et al 2010). Our results indicate that a tillage that brings the seeds at ≥ 0.1 m depths could cause approximately 10-20% seed mortality by fatal germination.…”

Martinková Z., Honěk A. (2013): Fatal germination in barnyardgrass (Echinochloa crus-galli). Plant Protect. Sci., Seeds of weeds buried by tillage may germinate at depths from which seedlings cannot establish. In barnyardgrass (Echinochloa crus-galli) we investigated how fatal germination was influenced by the depth and time of seed burial. The proportion of germinated seeds decreased with burial depth to 0-20% at ≥ 0.1 m depth which is fatal for seedling establishment. The percentage of fatal germination was greater for the seeds buried during the spring season than during autumn. Germination was influenced by seed pre-treatment, after ripening or stratification. Spring ploughing of non-dormant seeds below 0.1 m depth induces fatal germination, decreasing in this way seed bank of barnyardgrass.
