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

Antwortdetails

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.

Antwortdetails

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.
