It is shown and proved then the first and mass seedling emergence 2 days faster due to cell 4х4 and 2,5 × 2,5 cm compere to cell 6 х 6 cm. Growth period from transplanting to budding of plants grown from cells 2,5 × 2,5 cm was 19 days only. It was shortest and 4 days earlier compere to plants from cell 6 × 6 cm or direct sowing. Longest growth period from transplanting to budding of plants was 30 days due to cassettes with cells 2,5 × 2,5 cm. Plants from seedlings longer formed first yield. It was 44 days which was 7 days longer compere with direct sowing. The most active growth of foliage of the Basil plant observed before transplanting to open soil due to cells 6х6 cm. The leaves surface was high. Plants which grown in cassettes with cells 4х4 and 6х6 cm had better biometric data.
It was indicated then with increasing of substrate volume seedling quality indicators increased as well. Most active process of leaf surface growth in basil plants took place, which were grown in cassettes with a cell volume of 6 × 6 cm and before planting it in open ground, the leaf surface area was high. Regardless of the time of sowing seeds and planting seedlings in the open ground, the best biometric indicators were plants grown in cassettes with a cell volume of 6×6 cm, that is, with increasing food area per plant and seedling quality indicators increased. The longest peduncle (10,1 cm) had plants of second term of transplanting due to cells 4×4 and 6х6 cm . Higher yield had plants grown from cells 4 × 4 and 6 × 6 cm. Their yield was from 24,6 to 27,2 t/ha. Yield increase according to control was from 0,6 to 2,2 t/ha. Lowest yield shown plants which were grown in cassettes with volume of cells 2,5 × 2,5 cm from 20,9 to 24,3 t/ha.
