A proposed alternative production regime for cherry and grape tomato using compact plants and once-over harvest

Abstract

This report presents preliminary data and arguments supporting the investigation and possible adoption of a low-cost method of cherry and grape tomato (Solanum lycopersicum) production. Cherry and grape tomato crops are currently grown using indeterminate or relatively large determinate plants requiring trellising and significant hand labor at harvest. In contrast, processing tomato crops are usually determinate cultivars raised without supporting systems, and they are harvested mechanically. In Summer 2009, a Mississippi trial of home garden tomato cultivars included a compact, mounding yellow-fruited cherry tomato that produced more than 2 kg of fruit per plant in the first harvest. The architecture of the plant, high yield potential, and concentrated set indicate that there is potential to grow commercial cherry and grape tomato crops in much the same way commercial processing tomatoes are grown: unsupported on bare or mulched beds, with once-over harvest. Such a system could reduce the monetary and labor costs of production of cherry and grape tomatoes. Seed companies, tomato growers, and supporting agencies should work together to further investigate the potential of this system of cherry and grape tomato production.
