Growth and yield of lettuce (Lactuca sativa L.) as influenced by methods of raising seedlings under two types of cultivation system
In temperate areas, lettuce is one of the leading commercial vegetables, whereas in the tropics, it is a secondary vegetable of small but increasing commercial importance. Its production however needs a closer attention. This study was conducted at the Visayas State University to evaluate the performance and profitability of lettuce grown under tunnel type structure and open field condition using different methods of raising seedlings. The experiment was laid out in split-plot design arranged in RCBD with 3 replications. The type of cultivation as open field and protected cultivation using tunnel structure covered with net served as the main plot and methods of raising seedlings as the sub-plot. The types of cultivation did not significantly affect lettuce performance. However, protected cultivation produced plants with numerically better performance as well as net return. In terms of the methods of raising seedlings, lettuce plants produced from seedlings grown in a seedling tray through direct sowing into cell showed consistent superiority in all parameters than other methods, hence, generated the highest profit in both cultivation systems.
