Abstract Background In the almost century since the establishment of boron (B) as an essential plant nutrient, its roles in plant growth and development have been identified, and the mechanism for B transportation explained. Scope This review relates the yield response of crops, measured as B efficiency i.e. productivity when B is limiting relative to when it is not, to the B supply logistics and requirement of different tissues and organs. Conclusions Yield is depressed by B deficiency in graminaceous cereals primarily by impaired development and function of the stamen and pistil, but in dicots the adverse effects are expressed as structural damage to various organs. Boron-efficient cereal genotypes are readily identifiable by their successful grain set under limited B, while the quantitative trait loci associated with B efficiency provide a useful selection tool for Responsible Editor: Philip John White.

dicots. The relevance to breeding for B efficiency of the numerous BOR1 and NIP genes controlling active B transport identified in many crops will depend on how close their up-regulation in a deficiency is associated with B efficiency. Understanding of the yield impact of B deficiency is useful in dealing with crop choice and the management of germplasm and B fertilizer. Keywords Boron efficiency . Dicots . Field crops .

Introduction Boron (B) application was first found to increase the yield of oilseed rape (or canola, Brassica napus), turnip (B. rapa), maize (Zea mays) in France in 1910, and potato (Solanum tuberosum) and bean (Phaseolus vulgaris) in the US in 1920–1922, before the discovery that B was essential for plant growth was made by Katherine Warington in 1923 (Shorrocks 1997). These findings were soon followed in the next decades with reports of yield responses to B in tree and perennial crops, e.g. in olive (Olea europea) (Scott et al. 1943), grape (Vitis vinifera) (Scott 1944), and citrus (Haas 1945). Globally positive responses to B application had been reported in numerous crops in more than 80 countries by the 1990s (Shorrocks 1997), and continued to be added to as studies have reached new areas and production conditions, e.g. durum wheat (Triticum durum) in Turkey (Soylu et al. 2004, 2005), winter
