A study of probable plant spacing in field crop and vegetable plantations and their corresponding yields by sowing seeds at exact intervals and growing without thinning have been carried out. Mathematical coherences for the determination of the plant spacing density and their distribution were obtained. It is stated that the plant spacing density is a function of the seed germination power in the field. The lower is the germinating power; the higher is the irregularity of the seedlings, i.e. the number of the longer spacing increases. The obtained coherences allow to prognosticate the irregularity of the seedlings depending on the expected seed germinating power and to specify the standard quantitative of seeds per hectare. A formula is obtained for the estimation of field crop and vegetable yields depending on plant density.
