Effect of Late Cultivation under Low Tunnels on the Growth and Productivity of Some Leafy Vegetables

Abstract

The experiment was carried out in 2022-2023, on agricultural land in Idlib governorate, in the West Northern of Syrie. Experimental treatments were planted under low tunnels and covered with transparent plastic, to study the effect of late planting of spinach and lettuce crops in protected conditions. The seeds of local varieties of spinach and lettuce were used for the research. The experiment was carried out according to a randomized complete block design.

The experiment results indicated that using protected cultivation methods led to significantly better outcomes in various aspects compared to open-field cultivation. For both spinach and lettuce crops, protected cultivation resulted in higher seed germination percentage (1.3 times), increased leaf area of seedlings (3.3 times), more marketable plants (1.8 times), greater number of leaves per plant (1.3 times), taller plant height (1.3 times), higher seedling weight (3 times), and greater plant weight at harvest (1.5 times). Overall, the total productivity per unit area increased using protected cultivation. The average increase rate for all studied traits was 1.9 times higher in protected cultivation compared to open cultivation. As a result, we recommend late cultivation of spinach and lettuce crops under low tunnels to shorten the cultivation period after the completion of long-season summer cultivation.
