Abstract

the growth process and root quality. However, few studies are evaluating the influence of the interaction between nutrients in this culture. The objective of this work was to evaluate the effects of the combination of nitrogen fertilization with boron on the production characteristics and quality of the beet Tall Top Early Wonder. The experiment was carried out at the São Manuel Experimental Farm (FCA/Unesp), located in São Manuel-SP. The experimental design was in randomized blocks, with four replications. The evaluated factors were: nitrogen and boric fertilization, in the factorial scheme (2 x 2), totaling 4 treatments: T1 (0 kg ha-1 of N and 0 kg ha-1 of B), T2 (0 kg ha-1 of N and 4 kg ha-1 of B), T3 (90 kg ha-1 of N and 0 kg ha-1 of B) and T4 (90 kg ha-1 of N and 4 kg ha-1 of B). The results showed that there was a positive interaction between nitrogen and boron when applied together, providing increases in productivity and greater uniformity in beetroots.

Highlights

The beet (Beta vulgaris L.) belongs to the Chenopodiaceae family, typical of temperate climate, originating center on the Mediterranean coast region and North Africa (Tiveli et al, 2011)
The experiment was implemented at the São Manuel Experimental Farm, located in the municipality of São Manuel SP, belonging to the Faculty of Agronomic Sciences (FCA) of the Universidade Estadual Paulista (UNESP), Botucatu Campus - SP, from March to June 2019
The results obtained in the chemical analysis of the soil, before installation indicated: pH (CaCl2) = 6,5; organic matter content = 19 g dm-3; H+Al3+ = 9 mmolcdm-3; K = 2,5 mmolcdm-3; P = 165 mg dm-3; Ca = 33 mmolcdm-3; Mg = 9 mmolcdm-3; soil base sum = 43 mmolcdm-3; cation exchange capacity (CEC) = 52 mmolcdm-3; soil base saturation = 82; S = 13 mg dm3; B = 0,14 mg dm-3; Cu = 2,5 mg dm-3; Fe = 58 mg dm-3; Mn = 4,7 mg dm-3 e Zn = 3,6 mg dm-3

Summary

Introduction

The beet (Beta vulgaris L.) belongs to the Chenopodiaceae family, typical of temperate climate, originating center on the Mediterranean coast region and North Africa (Tiveli et al, 2011). This vegetable stands out for having in its chemical composition, various nutritional properties beneficial to human health such as vitamins (B1, B2, B5 and C), potassium, iron, copper, zinc, manganese and bioactive compounds with antioxidant effects as phenolic compounds, flavonoids, anthocyanins and betalains (Sediyama et al, 2010; Mikołajczyk-bator & Pawlak, 2016). The balance between macro and micronutrients improves the nutritional status of the plant, provides gains in production and product quality, and reduce spending on fertilizers and pesticides (Faquin & Andrade, 2004)
