The influence of seed sowing times on the growth, development and yield formation of basil (Ocimum basilicum L.)
Journal Title: «Таврійський науковий вісник» - Year 2017, Vol 97, Issue
Abstract
The effect of different dates of sowing the seeds of five basil cultivars on phenology, biometric parameters and productivity of plants was investigated in the article. In particular, the onset and duration of phenological phases of development, such biometric parameters as plant height, the diameter of the root collar, diameter of plants, leaf area and number of leaves were studied. It was determined that seed sowing in the second ten-day period of March contributed to the rapid onset of phenological phases for all basil cultivars: finished seedlings of Badoryi cv., Filosof cv. and Purpurova zoria were acquired 7 days earlier; and of Rutan cv. And Siaivo cv.-9 days earlier; first harvest– 10-12 days earlier. Sowing the seeds in later terms contributed to higher quality of the seedlings and forming branched bushes of all basil cultivars. The structure of the harvest of all basil cultivars was analyzed and it was established that sowing seeds in early terms (3rd ten-day period of February) reduced weight and increased percentage of stems. Terms of seed sowing also affect the growth of green mass after cutting, and therefore the yield as a whole. When the seeds were sown in March and April, basil was characterized by faster regrowth after cutting of green harvest, which made it possible to have 5 cuttings of green mass in all cultivars. When the seeds were sown in February, 5 cuttings received only in basil with purple leaves (Filosof and Purpurova zoria. The highest yield of all cultivars was observed under March sowing time – 8.48 kg/m2 and an amount of dry mass of 0.90 kg/m2 .
