The influence of Boron on pepper plants nutritional status and nutrient efficiency

Abstract

Boron may affect total uptake of various nutrients and their nutrient use efficiency (NUE) which results in high productivity and low fertilizer cost. Therefore, the objective of this study was to investigate the effect of boron concentration in nutrient solution on total uptake of the various nutrients and their utilization efficiency in pepper plants (Capsicum annuum L.). Four cultivars (Osho, Solario, Odysseo and Arlequin) were treated with 0.5-10 mg B L -1 . Each treatment included five replications with 3 plants and after 20, 40 and 70 days in culture one plant per pot was removed, divided into leaves, shoots and roots and analysed. The cultivars Odysseo and Arlequin have the greatest total phosphorus absorption at 0.5-2.5 mg B L -1 and more Ca at 1-2.5 mg B L -1 , while Odysseo absorbed more magnesium (Mg) per plant at 1 mg B L -1 and 70 d per plant than the other cultivars. Furthermore, Solario, Odysseo, and Arlequin absorbed at 70 days more B. Differences were recorded also among the cultivars concerning the rest of the nutrients. The maximum nutrient use efficiency of Solario and Osho for phosphorus and potassium was recorded at 5 mg B L -1 , and in Solario for calcium. Boron use efficiency was maximum for Solario, Osho and Odysseo at 0.5 mg B L -1 and for Fe at 10 mg B L -1 for all the cultivars. The effect of boron on magnesium, manganese and zinc use efficiency was variable.

Chestnut Response to Organo-mineral and Controlled-Release Fertilizers in Rainfed Growing Conditions

“…As previously mentioned, Exactyon AG 18:5:13 gave significantly higher nut yields than the control. Previous studies have highlighted the importance of B for chestnut (Portela et al 2011(Portela et al , 2015 and In columns, separated by year, means followed by the same letter are not significantly different by Tukey HSD test (α = 0.05) several other dicot species (Liakopoulos et al 2005;Soyergin 2010;Sarafi et al 2018;Arrobas et al 2019). This result also suggests that part of the increase in nut productivity might be due to the better B nutrition of the trees fertilized with Exactyon AG 18:5:13.…”

With or Without You: Altered Plant Response to Boron-Deficiency in Hydroponically Grown Grapevines Infected by Grapevine Pinot Gris Virus Suggests a Relation Between Grapevine Leaf Mottling and Deformation Symptom Occurrence and Boron Plant Availability

“…In the literature, information on the relationships between B-related growth conditions and the homeostasis of the other nutrients is lacking (Tariq and Mott, 2007). In fact, conflicting results have been obtained using different crop species and growth techniques, and also analyzing various plant parts at different growth stages (Lombin and Bates, 1982;Singh and Singh, 1984;Carpena and Carpena-Ruiz, 1987;Mozafar, 1989;Agbenin et al, 1990;Zhou et al, 2014;Sarafi et al, 2018). Unfortunately, to our knowledge, nutrient content measurements have never been carried out in grapevines under B deprivation.…”

The retranslocation of boron is influenced by the nutritional status of cherry tomato plants

“…According to Eggert and von Wirén (2017), nutritional status B causes coordinated changes in plant hormone metabolism as a prerequisite for an adjusted growth response. In this context, it was observed that B influenced the nutritional status and nutritional efficiency in pepper plants, with different responses depending on genotype, B concentration and the nutrient (SARAFI et al, 2018). Thus, B deficiency in K+B-treatment could have promoted the retranslocation in cherry tomato plants as a physiological response, such as observed in radish plants (TARIQ;MOTT, 2006).…”
