Abstract

Organic vegetables have gotten an increasing interest, but organic fertilizers and irrigation water used to produce them could be significant issues of economic calculation to be considered for some locations. This study was aimed to determine the optimum doses of organic compost and irrigation level for growing organic red lettuce in a greenhouse. Completely Random Design (CRD) coupled with factorial arrangement was implemented in this study. Treatments consisted of two factors; doses of organic compost (D) and regulated irrigation levels (I). The factor of doses included 0% (D0), 10% (D1), 30% (D2), and 50% (D3) organic compost of the total weight of the growth media (3 kg per pot). The factor of regulated irrigation levels included 40% (I1), 70% (I2), and 100% (I3) of available water. Three replicates were used, making total of 36 experimental units. Plants were cultivated in a greenhouse, using pots each of which contained 3 kg media, and watered regularly based on the treatments assigned. The data set was analyzed by using Analysis of Variance (ANOVA) and followed by least significant differences (LSD) at α= 5%. The result showed that interaction effect between organic compost doses and irrigation levels on the growth, yield, and water productivity of the red rapid lettuce was significant at α = 0.05. However, the treatments were not significant on some chemical properties of the rapid red lettuce. The most optimum scheme was found to be the treatment combination between the organic compost dose of 300 g plant-1 (D1) and the regulated irrigation level at 100% (I3) of available water.
