Abstract
Grain yield of Phaseolus vulgaris in a function of application of boron in soil
Highlights
Common beans (Phaseolus vulgaris L.) is a basic food, with a high socio-economic importance to Brazil (Richetti et al, 2013)
B is essential to many plant physiological processes such as transport of sugars, cell wall synthesis, lignification, cell wall structure, carbohydrate metabolism, RNA metabolism, respiration, IAA metabolism, phenolic metabolism, ascorbate metabolism, germination and pollen tube growth
B is related with physiological activity in crops, which may block the chlorophyll synthesis and, as a consequence, the photosynthetic activity in plants with B deficiency (Yadegari. 2016)
Summary
Common beans (Phaseolus vulgaris L.) is a basic food, with a high socio-economic importance to Brazil (Richetti et al, 2013). In production systems aiming high productivities, a proper management of mineral fertilization programs required to maintain the nutritional balance of plants is essential. Required in smaller quantities, micronutrients are very important for the growth, development and production of dry beans. Boron (B) has a narrow range of suitable contents and toxic contents in the soil solution. This evidences the need for further calibration of its supply via fertilization management (Trautmann et al, 2014). The low natural boron content in the soil has been a limiting factor for the production of common bean grains in Brazilian tropical regions (Mattiello et al, 2009; Euba Neto et al, 2014). According with Wasaya et al (2017), plants with adequate B levels are more tolerant to abiotic stress
