TI - Tomato spacing: Close spacing increased early yields in 1946–1949 experiments JF - California Agriculture JO - Calif Agr Y1 - 1950/05/01 VL - 4 IS - 5 SP - 10 EP - 12 PB - University of California Agriculture and Nature Resources SN - 0008-0845 UR - http://www.ucanr.edu/sites/calagjournal/archive/?article=ca.v004n05p10 AB - Plant spacing trials for canning tomatoes were initiated in Yolo County in 1946. Since the introduction of the field seeded method plant spacing has become of special interest to tomato growers. In this method, the cost of establishing the field is the same regardless of the spacing, while in transplanted fields the cost will increase with closer spacings.
