Cinnamon yam yield as affected by growing system
Global climate changes have enabled the expansion of tropical and subtropical crops cultivation areas in moderate climate. The aim of study was to determine the possibility of cinnamon yam (Dioscorea oppositifolia L.) production, using three growing systems. Seedlings were grown in a heated greenhouse and planted to the open field in the first decade of May. Conventional technology, which involves free development of tubers in the soil, was used as control. Also, planting in channels buried in the soil at the angle of 25° and in vertical peat-filled basins placed at the soil surface were tested. Depending on the applied growing system plant density was between 5.5 plants per m2 in conventional technology and 9 plants per m2 in vertical basins. Developed tubers were significantly different in length, which ranged from 0.36 m in conventional technology to 0.95 m in vertical basins. The highest diameter of basal part (8.6 mm) is determined at the tubers grown in the channels and was significantly higher than the others. Apex diameter of the tubers was statistically equal and varied from 19.6 to 23.3 mm. Tubers with the lowest weight (149.7 g) were produced by conventional method, while the highest tuber weight (225.1 g) was achieved in vertical basins. Tubers grown in the vertical basins had equable weight, what can be concluded from the standard deviation value (19.5 compared to 41.5 and 58.6 for the control and channels). The highest yield (2.03 kg•m-2) was achieved in vertical basins and was significantly higher than yields gained by other technologies. Beside plant density, which is higher than at the other growing systems, the higher tuber mass and length contributed to achieving the highest yield in vertical basins.
