“…The amount of N accumulated in the shoot was similar to that found by Oliveira et al (2017), 106.5 mg per plant. The N absorbed by the tuberous roots is assimilated during the formation of nitrogenous compounds in the plant, with a link between the absorption of N and the increase in yield (OLIVEIRA et al, 2017).…”

An experiment was carried out aiming to evaluate the effect of phosphorus rates on beet, in an Oxisol with high phosphorus (P) content, in Jaboticabal city, São Paulo, Brazil. The treatments were arranged in a factorial scheme, in a randomized block experimental design with four replicates. The factors evaluated were P rates (0, 120, 240, 360 and 480 kg ha-1 P2O5) and cultivar ('Early Wonder' and 'Kestrel'). At 50 days after transplanting the seedlings, foliar nitrogen (N), P, potassium (K) and boron (B) contents were evaluated, and there was no effect of the interaction between factors on foliar nutrient contents. The accumulation of these four nutrients was evaluated at harvest. All evaluated nutrients accumulated to higher levels in ‘Early Wonder’ than in 'Kestrel' both in the shoots and tuberous root. N, P and B accumulated more in the tuberous root whilst K accumulated more in the shoots. P dose did not influence the yield. Therefore, phosphate fertilization is not recommended for beet crop when cultivated in an Oxisol with a high content (88 mg dm-3) of available P.

“…Increments for SPAD index throughout the crop cycle might be explained for its nitrogen disponibility from the real-time process of nutrient mineralization for the plants, taking into consideration the significative interrelation among the intensity of green color, chlorophyll content and N concentration in leaves (Oliveira et al, 2017;Aquino et al, 2006;Pôrto et al, 2011).…”

This study aimed to evaluate the effects of doses of nitrogen fertilizer in association with types of basal dressing fertilizers on the physiological characteristics of beet cultivar Early Wonder in a protected environment. The experiment was conducted in safe environment at the Federal University of Campina Grande, using a randomized block design with three replications and a 5x3 factorial scheme, in five doses of nitrogen (0, 50, 100, 150 and 200 mg dm-3) applied through fertigation, and three types of basal dressing fertilizers (unfertilized soil, earthworm humus and earthworm humus + NPK). At 45 and 90 days after transplanting (DAT), it was determined the chlorophylls a, b, total chlorophylls, carotenoids and SPAD index. Organo-mineral fertilizer (earthworm humus + NPK) provides greater efficiency for the photosynthetic pigments when compared with organic fertilizer (earthworm humus) and without fertilization (control).The increase of nitrogen dose up to 200 mg dm-3 is the one which contributes most to the increment of chloroplastid pigments. Nutrients were absorbed by the plants and the humus and humus + NPK treatments supplied the nutritional demands during the beet cultivation cycle.

Agronomic biofortification is a technique that helps reduce hidden hunger worldwide. Zinc (Zn) is important for human health and essential for plant development and growth. Thus, this research aimed to evaluate the effects of fertilization with Zn on agronomic performance and the agronomic biofortification of beet. Two experiments were conducted at the Rafael Fernandes Experimental Farm, belonging to the Federal Rural University of the Semi-arid, in Mossoró-RN. Each experiment was designed in complete randomized blocks, with five treatments and four replications. The treatments consisted of Zn doses (0, 1.5, 3.0, 4.5, and 6.0 kg ha−1). Zn fertilization did not affect the total and non-commercial yield of beet; however, the dose of 6.0 kg ha−1 of Zn promoted maximum commercial yield (20.34 t ha−1). At the maximum dose, higher Zn content was also observed in the nutritional status diagnosis leaf and higher Zn accumulation was found in the leaf, tuberous root, and throughout the plant. There was also an effect on postharvest variables. There was only tuberous root biofortification in 2021. The recommended dose in beet cultivation is 6.0 kg ha−1 of Zn.
