Abstract

Lettuce plants were set into two factors A and B wherein A stands for the main plot aerated/non-aerated condition and B for sub-plot or the different nutrients used under greenhouse condition. Factor B consisted of T1: Control (water only), T2: SNAP (simple nutrient solution programme), T3: Masterblend (lettuce), T4: Masterblend (tomato) fertilizer and T5: Humus plus foliar fertilizer under hydroponic condition. The research was carried out following the split-plot design with three replications. All treatments of the two sub-plots and two sub-plots (average all over main plot) were statistically significant according to the study’s findings. In the main plot, both aerated and nonaerated lettuce conditions were found to have a significant impact on plant height at 35 days after transplanting and average weight per plant with the exception of the number of leaves which was found to be non-significant and did not tend to increase the number of leaves. Plants grown in treatment comprising masterblend for tomato also gained a higher weight per plant. When the solution was not aerated, the pH tended to be neutral however when it was aerated, it became alkaline. With 77.97 per cent, the plants produced in treatment masterblend for tomato under aerated yielded the highest investment return. This study represents a step forward in achieving higher yields in hydroponic lettuce grown in an aerated environment with masterblend (tomato) fertilizer.
