“…The yield of cauliflower plants was favored up to a dose of 5 kg ha -1 , but negatively affected with higher doses (NAZIR et al, 2019). In Brazil, peanut productivity showed a reduction in response to higher doses of B via leaf (MANTOVANI et al, 2013). In northeast of Pará, the highest doses of B caused less production of dry mass of the aerial part and inflorescence in cauliflower plants (Brassica sylvestris (L.) Mill.)…”

Due to the increasing national and international demand, the cultivation of açaí palm trees (Euterpe oleracea Mart.) has expanded to upland areas in Brazil. Most of these areas present low natural soil fertility, in which boron (B) is one of the most limiting nutrients. This study aimed to evaluate the productivity of fresh fruits of fertigated açaí trees submitted to doses of B. The study was carried out in Tomé-Açu, northeastern Pará, Brazil. The experimental design consisted of randomized blocks with four treatments: control and addition of 20, 40 and 60 g of B clump-1. After 17 months, bunches of fresh fruits were collected and the production per hectare was estimated. An economic analysis was carried out considering the costs of fertilization and fruit production. The productivities obtained in the treatments were considered above the average of the municipality of Tomé-Açu. The estimated content of leaf B that provided the highest productivity was 14.9 mg kg-1, for a yield of 5479 kg ha-1 year-1¸ while the critical content corresponded to 13.2 mg kg-1. The highest productivity of fresh açaí fruits was achieved with the dose of 20 g of B clump-1, which provided a net gain of 42%.

“…According to Mantovani et al (2013), B enhances the fixation of flower and grain formation in different cultures, and provides less male sterility and lower pith grains, which possibly influenced the grain yield in this study. The nutritional requirement of the cultivated plants generally becomes more intense with the beginning of the reproductive phase, because the crops are in full vegetative development, added to the strong demand for nutrients for the formation of the reproductive structures, the relatively low quantities of B required by the crop in general can be met by foliar fertilization.…”

“…The lack of B is very common in tropical soils, which has caused great productivity losses in different crops (Mantovani et al, 2013). In addition, the amounts of B required for seed formation are generally greater than those required for vegetative growth (Marschner, 1995).…”

“…As a result of its low mobility within the phloem, there is a need for a constant availability or supply of this nutrient during the vegetative phase of the plants (Calonego et al, 2010;Mantovani et al, 2013), being important studies about the ideal moment management of fertilized fertilization. However, there are few studies on B fertilization in wheat cultivation focusing on the best application method associated with the appropriate dose of this nutrient.…”

Boron is one of the most limiting micronutrients in grains production system in Brazil. In this way, the objective was to evaluate the effect of forms of application and doses of boron in irrigated wheat grain yield evaluating the economic terms in Cerrado region. The experiment was conducted in no-tillage system in an Oxisol with clay texture in Selvíria, MS, Brazil. The experimental design was a randomized block design with four replicates, arranged in a 4 × 3 factorial scheme: four doses of boron (0, 1, 2 and 4 kg ha -1 ) with boric acid source (B = 17%); and three apllication forms: a) in desiccation of the predecessor straw, together with herbicide; b) at the time of sowing, in soil along with the formulated fertilization seeding and c) via leaf tissue with the application of post emergent herbicide. The application of 2 kg ha -1 provides greater grain yields, but the highest economic return was obtained at the dose of 1 kg ha -1 , with application in soil, ensuring profitability from production of irrigated wheat in the Cerrado.

The foliar application and seed Ca + B, Mo + P and Stimulate ® in peanut, despite being a practice used long ago, few studies have conclusive results, and then this research was to evaluate the physical and physiological quality peanut seeds from the process of application of fertilizers and bio-stimulant. The design was completely randomized, with seed from peanut plants subjected to the use of three products (Ca + B; Mo + P and Stimulate ® ), two types of applications (via leaf and seeds), growing with PK and absolute control, following a factorial arrangement of [(3 × 2) + 2]. For the dimensions (length and width) of seeds, as well as the thousand seed weight and number of seeds per pod, data were submitted to descriptive statistics, calculating the mean, standard deviation, variance and coefficient of variation of the data obtained. The application of fertilizers, bio-stimulants and groundnut seeds increases germination of seeds produced, causes more seedlings that are vigorous and reduces the percentage of abnormal seedlings.
