Temperature

Maelezo ya Majibu

The condition that is not necessary for germination is "zero temperature." All seeds require an optimum temperature range for successful germination, which varies among different plant species. While some seeds may require a specific temperature, such as stratification or scarification to overcome dormancy, no seeds can germinate at zero temperature. Therefore, the correct statement is: The following conditions are necessary for germination except zero temperature: - adequate moisture - viable seed - optimum temperature

Seeds are raised in the nursery for several reasons, including: - To protect them from harsh environmental conditions, such as extreme temperatures or heavy rain, which could damage or kill the seeds. - To provide them with a controlled environment with optimal growing conditions, such as the right amount of water, nutrients, and light. - To monitor and manage pests and diseases that could harm the seeds. - To allow for easier transplanting and handling of the seedlings once they are ready to be moved to their final growing location.

The type of ration that supplies the animal with just the quantity of nutrients that are enough to enable the animal to carry on with vital body activities without losing or gaining another substance is called the "maintenance ration." A production ration is designed to provide nutrients for specific animal production goals, such as milk production or weight gain. A balanced ration is formulated to provide all the necessary nutrients in appropriate amounts to meet the animal's needs. A measured ration is a ration in which feed ingredients are weighed or measured out in specific amounts to meet the animal's nutrient requirements.
