The stale seed bed technique of weed control was developed before herbicide use began. It reduces the soil's seed bank or quantity by allowing the weed seeds both opportunity and time to germinate, sprout, and appear before the intended crop is planted. Once the weeds appear, they are easily eliminated by various methods that minimize further ...
Using thermal and chemical scarification, germination increased to 48.8% and 44% respectively. 68% of Longspur lupine seeds germinated in the control group, while all scarification methods decreased the success rate of germination. The silvery lupine had 52% of its control group germinate but through mechanical scarification it rose to 85.2%.
True dormancy or inherent (or innate) dormancy is caused by conditions within the seed that prevent germination even if the conditions are favorable. [7] Imposed dormancy is caused by the external conditions that remain unsuitable for germination [8] Seed dormancy can be divided into two major categories based on what part of the seed produces dormancy: exogenous and endogenous. [9]
Weed control is a type of pest control, which attempts to stop or reduce growth of weeds, especially noxious weeds, with the aim of reducing their competition with desired flora and fauna including domesticated plants and livestock, and in natural settings preventing non native species competing with native species.
The result is an increased rate of germination, and a much-improved crop yield (up to eight times compared to broadcast seeding [7]). The use of a seed drill also facilitates weed control. Broadcast seeding results in a random array of growing crops, making it difficult to control weeds using any method other than hand weeding.
[11] [12] The seeds of some milkweeds need periods of cold treatment (cold stratification) before they will germinate. [13] To protect seeds from washing away during heavy rains and from seed–eating birds, one can cover the seeds with a light fabric or with an 0.5 in (13 mm) layer of straw mulch. [14] However, mulch acts as an insulator ...
The actor and marijuana entrepreneur spoke about the ups and downs of his career in Hollywood, including passing on "Jerry Maguire." I quit weed but Willie Nelson brought me back: Harrelson [Video ...
In colder climates they are sometimes used for plants like peppers and sweet peas which need warmer environments (about 15°C, for the plants listed) in order to germinate. If excessive condensation forms on the inside of the lid, the gardener can open the ventilating holes to regulate the temperature a little.
