“…Weed species populations are dynamic and change in time, spread and environment (Booth et al, 2003). Their seedling number is directly proportional to the temperature and soil humidity potential (Grundy, 1997) as well as the depth of the seed burial in the soil (Colbach et al, 2006). Analysis of variance of weed number and mass revealed the significant influence of primary soil tillage (factor A) on the examined indicators of weediness (Table 2).…”

Little is known about the influence of deep loosening and its combination with primary soil tillage and organic fertilizers on weed incidence in crops. The aim of the study was to determine the influence of different soil tillage methods and their combinations with deep loosening and organic fertilizers on the weed incidence in a crop rotation. An experiment was carried out at Vėžaičiai Branch of Lithuanian Research Centre for Agriculture and Forestry during the period 2012-2015 in a four-course crop rotation: winter wheat → spring rape → spring barley with undersown red clover → red clover. The soil of the experimental site is Dystri-Epihypogleyic Albeluvisol (ABg-p-w-dy) with a sandy loam texture. Soil tillage methods (conventional ploughing, shallow ploughing, shallow ploughless tillage), organic fertilizers (without organic fertilizers, straw, green manure 1 st cut + straw, green manure 2 nd cut + straw, farmyard manure 40 t ha -1 + straw) and deep loosening impact on weed incidence was very unequal during the experimental years and depended on plant growth and development conditions. In all experimental years, primary tillage had the main influence on the examined indicators of weed incidence (weed number and dry mass). Significantly greater number and mass of weeds were established in shallow ploughed soil. Organic fertilizers did not have any significant influence on the indicators of weed incidence; however, the use of red clover of the first cut for green manure tended to reduce weed number in the crops of the rotation during the first half of the plant growing season. A significant influence of a onetime deep loosening was observed in the first year. After improving soil aeration and humidity conditions, weed number and dry mass were significantly greater, compared to unloosened plots. The interaction between deep loosening and soil tillage methods had a great effect as well. Having used deep loosening in shallow ploughless tillage treatments, the weed number was greater compared to deeply ploughed soil.

“…Germination also decreases with seed depth, even if moisture, O 2 and light are the same (Colbach et al, 2006;Sester et al, 2007;Gardarin et al, 2010a). A failure to emerge can result from insufficient germination or from pre-emergent mortality.…”

“…Various models have been developed to predict the persistence (Begg et al, 2006;Middelhoff et al, 2011), seed bank evolution and emergence (Colbach et al, 2008), fecundity and gene flow (Colbach et al, 2001a ,b;Gruber & Claupein, 2007) and seed bank dynamics (Gonzalez-Andujar & Fernandez-Quintanilla, 2004;Pekrun et al, 2005) of volunteer oilseed rape. Colbach & Debaeke (1998) showed the need to use mechanistic models instead of empirical models. In mechanistic models, the life-cycle is split into sub-processes to account for the biological and physical effects of cropping systems interacting with the biological (e.g., structure of the crop) and physical environment (e.g., soil structure) of weeds (Colbach & Debaeke, 1998;Colbach et.…”

“…Additionally, temperature and water potential have been successfully combined into a hydrothermal time model (HTT) (Gummerson, 1986;Bradford, 1995Bradford, , 2002. Using this model base values (ψ b and T b ), TT, HT and HTT would be calculable, which can be used in seed bank population dynamic models (Colbach et al, 2006;Sester et al, 2007). There is no information available regarding HTT models of oilseed rape.…”

-Studies were conducted to estimate parameters and relationships associated with sub-processes in soil seed banks of oilseed rape in Gorgan, Iran. After one month of burial, seed viability decreased to 39%, with a slope of 2.03% per day, and subsequently decreased with a lower slope of 0.01 until 365 days following burial in the soil. Germinability remained at its highest value in autumn and winter and decreased from spring to the last month of summer. Non-dormant seeds of volunteer oilseed rape did not germinate at temperatures lower than 3.
