Evaluation of Alternative Cultivators for Vegetable Production

Richard Smith, University of California, Davis

A field trial in the Salinas Valley compared a brush hoe cultivator (Bartchi Fobro Co., Switzerland) to conventional cultivators for weed control in cool-season vegetables. Seven on-farm trials showed the brush hoe cultivated closer to the seed row (2 7/8 inches versus 4 inches), resulting in comparable or better weed control. Under heavy weed infestations, the brush hoe saved over four hours of weeding/thinning time per acre. However, at lower weed densities (1.5–2.0 weeds per foot of row), time savings were inconsistent. The brush hoe operated at a slower speed (2.5–3 mph versus 4–5 mph) and needed an extra operator for accurate cultivation near the seedline. Therefore, while potentially beneficial for smaller operations with limited labor or high weed pressure, the brush hoe’s economic viability for large-scale vegetable production is questionable.
