Growth Characteristics and Quality of Cherry Tomatoes Planted with Nasturtiums, as a Companion Plant, in Building-Integrated Urban Agriculture

Urban Farm DB summary

This study analyzed the growth and quality of cherry tomatoes (CTs) and nasturtiums planted at different ratios (CTs only, 2:1, 1:1, 1:2, nasturtiums only) on rooftops and walls in building-integrated urban agriculture. Cherry tomatoes planted alone showed significant growth compared to companion planting. The 2:1 ratio of CTs to nasturtiums (C2N1) resulted in the highest plant weight and sugar concentrations for CTs on rooftops and walls, and nasturtiums also had larger leaves and flowers in this ratio. CTs generally grew better on walls than rooftops when companion planted with nasturtiums.
