Abstract

Abstract In general, single-harvest yields increased and spear weight decreased as the distance between broccoli plants ( Brassica oleracea L. Italica group) decreased. Cultivars differed considerably in maturity and percentage spears marketable in response to spacing. The best of the 9 cultivars studied for single-harvesting were: ‘Green Duke’, ‘Blue Ocean’, ‘S & G No. 1’ and ‘Atlantic’. It is suggested that these cultivars should be spaced within the range of 30 × 30 cm and 40 × 40 cm for optimum utilization under Prince Edward Island conditions.
