“…In other vegetables, the responses were also positive for dry matter production as a function of phosphate fertilization, as in carrots (Assunção et al, 2016), beetroot (Silva et al, 2019) and potatoes (Fernandes et al, 2015).…”

Phosphorus (P) is an important nutrient for obtaining high yields and has been the one that most often limits production. The objective of this study was to evaluate the agronomic performance of onion cultivars as a function of phosphate fertilization. The experiments were installed at the Rafael Fernandes Experimental Farm, of the Federal Rural University of the Semi-Arid Region, Mossoró-RN, Brazil, from July to October 2016 and from June to October 2017. The design used was randomized blocks, in a 2 x 6 factorial scheme, with four replicates. The treatments consisted of the combination of two onion cultivars (IPA11 and Rio das Antas) and six P doses (0, 60, 120, 180, 240 and 300 kg ha -1 P 2 O 5 ). The economical doses of P, associated with the maximum marketable yields of onion were estimated at 212.45 and 207.65 kg ha -1 of P 2 O 5 , respectively for the cultivars IPA 11 and Rio das Antas. In general, the cultivar Rio das Antas was more productive than IPA 11, in the two growing periods.

“…However, soils that are commonly cultivated with vegetables and are thus under intense management (acidity correction and fertilization) tend to have high fertility and it is not uncommon to have a high P content. There are few recent studies involving mineral nutrition and phosphate fertilization in beet crops (OLIVEIRA et al, 2016;SILVA;SILVA;KLAR, 2017 andSILVA et al, 2019), and all of them were carried out on soils with low levels of P, which is very different from the conditions, in general, found in large beet-producing areas.…”

Response of Beet to Phosphorus Rates in Oxisol With High Content of the Nutrient

et al. 2022

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.
