“…The sunflower cultivar Altis 99 has a median height (1.20m) when compared to other cultivars and, to obtain good productivity indices for this genotype, the average diameter of the chapter should be approximately 21cm (Soares et al, 2020), in this way, less developed chapters, will imply a lower production of achenes, compromising the efficiency of the production system.…”

The aim of this work was to increase the aerial part, biometry, and yield of achenes from sunflower plants on the effect of increasing doses of blood residue, as an alternative source of phosphorus (P), in a clayey-textured red Oxisol. The experimental design used was randomized blocks, with six treatments and four replications. The treatments consisted of five doses of blood residue (0, 6, 12, 24 and 48m3 ha-1) and a control treatment that received phosphate chemical fertilization, 80kg ha-1 of P2O5. The increasing doses of blood residue and chemical fertilization do not show disproportionality for P concentration in soil, leaf, plant height (PH), stem diameter (SD), chapter diameter (CD) and achene production. The analysis of the principal component (PC) revealed that the first PC presents the greatest accumulated variation (74%). Based on the first PC, the dose of 12m-3 ha-1 has greater influence for PH, SC, and CD. Due to the greater influence on the biometric characteristics of sunflower plants, the blood residue (12m-3 ha-1 = 98.4kg P ha-1), can be used as an alternative source of phosphorus for the cultivation of sunflower in clayey oxisols.

“…The growing demand for the oil and its derivatives has favored the expansion of sunflower crops in several regions of the world, many of which have semiarid climates (Li et al, 2017). In the Brazilian semiarid region, the expansion of this oilseed crop has seen a special focus in recent years, mainly after being inserted into the national energy matrix through the National Biodiesel Production and Use Program (Cavalcante Júnior et al, 2013;Soares et al, 2020).…”

Sunflower is one of the most important oilseeds in the world, whose achenes are valued in several industrial chains, mainly for the extraction and processing of its oil. Although there is some information in the literature, the nitrogen (N) requirements for sunflower in semiarid conditions under irrigation are not yet clear. The experimental design used randomized blocks, with treatments in subdivided plots with four replications during two agricultural seasons. The N doses (e.g., 0, 30, 60, 90 and 120 kg ha-1) were assigned to the plots, and to the four sunflower cultivars used (e.g., Aguará 06, Altis 99, Multissol and BRS 122), which were planted in the subplots. The N doses for the maximum achene yields for the Multissol and BRS 122 cultivars were 81.8 and 86.6 kg ha-1, respectively, while N doses of 120 kg ha-1 produced the maximum achene yields for the Altis 99 and Aguará 06 cultivars in the 2016 crop season. In 2017, the Multissol and BRS 122 cultivars were given N doses of 100.7 and 92.8 kg ha-1, respectively, and the Altis 99 and Aguará 06 cultivars were each given an N dose of 120 kg ha-1 of N. The fertirrigated doses of maximum economic efficiency of N were 60 and 70 kg ha-1 for the Multissol and BRS 122 cultivars, respectively. For the oil yields, the maximum N doses of 78.0 and 86.7 kg ha-1 for the BRS 122 and Aguará 06 cultivars and for the Multissol and Altis 99 cultivars at an N dose of 120 kg ha-1 were used for the 2016 harvest. In 2017, the BRS 122 and Multissol cultivars received N doses of 88.6 and 99.1 kg ha-1, respectively, and the Altis 99 and Aguará 06 cultivars received N doses of 120 kg ha-1. The use of fertigation allowed greater efficiency for the N doses in the sunflower cultivars in the semiarid region.

“…Available phosphate obsession in soils is the dominant proof for its low availability (Raghothama and Karthikeyan, 2005). Soares et al, (2020) indicated that phosphorus fertilization enhanced sunflower agricultural components, P volume in leaf, achenes yield, and oil yield. Kaya et al, (2001) noted that phosphorus plays an avital role in relieving negative salinity results on the entire plant biomass for all kinds of crop plants.…”

Two field experiments were conducted on saline clay soil in a split-split-plot design with four replicates. The main plots were arranged to study the effect of phosphoric acid applied with irrigation water ( without, 6 L ha -1 and 12 L ha -1 ) where subplots were occupied to with or without the zinc spray Zn (at 13% chelated on EDTA), While the sub-subplots were occupied to anti-stress foliar which included Salicylic acid SA (foliar spraying of 0.01 mM), foliar spraying of calcium (at 10% chelated on EDTA) and Salicylic acid with calcium (foliar spraying of 0.01mM with foliar spraying of calcium at 10% chelated on EDTA). Where the interaction between these treatments showed that using phosphoric acid (12 L ha -1 ) acid with zinc spray (at 13% chelated on EDTA) and spraying both salicylic acid (0.01 mM) and calcium (at 10% chelated on EDTA) together showed an effective effect on increasing growth, the yield of grains, oil content and salinity tolerance by reducing the concentration of sodium and chloride in the sunflower plant.
