Détails de la réponse

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.

The following conditions are necessary for germination except

Détails de la réponse

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

One of the followings is not a basic consideration in planting operations

Détails de la réponse

Planting weed is not a basic consideration in planting operations. The other options listed are all important factors to consider when planting, as they can affect the growth and development of the plants. Planting space determines how far apart to plant the seeds or seedlings, which affects how much space the plants will have to grow and how much light, water, and nutrients they will receive. Planting time is important because different plants have different requirements for temperature and moisture, and planting at the wrong time can result in poor growth or even the death of the plants. Planting depth is important because different seeds require different depths to germinate properly, and planting too shallow or too deep can affect the germination rate and the growth of the plants.
