Enhancing productivity of lettuce grown in vertical garden sprayed with various plant concoctions

Abstract

This study focused on determining which plant concoction as foliar spray would significantly promote lettuce growth in terms of plant height, leaf length, width of leaves, number of leaves, and leaf color; identify the performance of lettuce grown in a vertical garden sprayed with different plant concoctions. This was laid out in a 2×5 factorial experiment arranged in a Complete Randomized Design with three replications. Factor A variety comprised two lettuce varieties such as A1 Lollo Bionda and A2 Black Simpson and factor B as Plant concoctions five treatments: B1-water only, B2-fermented plant juice (FPJ), B3-fermented fruit juice (FFJ), B4-calcium phosphate (Calphos), and B5-oriental herbal nutrient (OHN) affect variables like plant height, leaf length, leaf color, and weight of marketable. The findings showed that OHN is more effective than other concoctions, considerably increasing plant growth, leaf development, and financial returns.  Regarding height, leaf size, and marketable weight, Lollo Bionda continuously outperformed Black Simpson, indicating that genetic heterogeneity across the lettuce types affecting how receptive they were to the mixtures. On the other hand, no significant interactions were observed between lettuce varieties and plant concoctions across all parameters. However, the result indicated that lettuce varieties responded similarly to plant concoctions. The findings suggest, that the best plant concoction to produce lettuce varieties grown in a greenhouse is Oriental Herbal Nutrient since it was observed that outshined across all parameters.
