“…Similar results have been reported by Callegari et al (2022) for 'paricá' (Schizolobium parahyba var. amazonicum) and Kume et al (2021) for maize (Zea mays L.), with reductions in the leaf concentrations of Fe and Mn as a function of Zn fertilization. This can be attributed to the antagonistic effect between Zn and Fe and between Zn and Mn in the processes of absorption, transport, and chemical reactions within plant cells (Rai et al, 2021;Almendros et al, 2022).…”

Zinc is an essential micronutrient for plant metabolism and has been studied in several crops of economic interest. However, there is no evidence of its use in coconut crops. The objective of this study was to evaluate the influence of foliar zinc fertilization with doses of zinc on dwarf green coconut seedlings based on their nutritional status, growth attributes, and gas exchange. The experimental design consisted of randomized blocks, and the treatments consisted of different zinc doses (0, 5, 10, 15, 20, and 25 g per plant) with five replicates. Seedlings were positively influenced by zinc dose, mainly in terms of growth variables and gas exchange. Zinc fertilization reduced iron and manganese content and increased zinc concentrations in the leaf tissue. Zinc fertilization promoted an increase in leaf area, height, shoot dry mass, and total dry mass. Furthermore, zinc fertilization improved photosynthesis, transpiration, stomatal conductance, internal CO2 concentration, instantaneous water use efficiency, and intrinsic water use efficiency. The improvement in these growth indices and gas exchange, in most variables, was up to an estimated dose of approximately 16 g of zinc per plant and decreased with increasing doses.

“…The results presented in Figures 3A and 3B demonstrate a competitive relationship between Fe and Zn, since as the Zn contents increased as a function of the biofertilizer doses, the arrowroot plants showed a significant reduction in Fe contents in their leaves. Similarly, Kume et al (2021) evaluated nutritional disorders caused by Zn deficiency and excess in maize plants and found an inverse relationship between the leaf contents of these elements; Fe contents decreased as Zn contents increased.…”

Arrowroot (Maranta arundinaceae) is a unconventional food plant (UFP) that has relevant nutritional properties. However, few studies on the species regarding its forms of propagation and its nutrition have been performed. In parallel, biofertilizer provides nutrients and stimulates the development of species, as it promotes improvements in soil properties. In this context, the objective in this study was to evaluate the effect of different forms of propagation and doses of biofertilizer on arrowroot nutrition. A randomized block experimental design in a split-plot scheme, evaluating three forms of propagation (whole rhizome, part of the rhizome and stem) and five doses of biofertilizer (0, 300, 600, 900 and 1200 mL per plant week-1) was used. At 268 days after planting, the leaves were collected for analysis of leaf macro and micronutrient contents. Plants propagated by stem have lower accumulation of N, P, K and S and higher accumulation of Na, compared to the other forms of propagation. N and K contents were increased by the application of biofertilizer, reaching values of 20.8 and 18.2 g kg-1 at doses of 1200 and 955 mL per plant week-1, respectively. Accumulation of micronutrients was influenced by the forms of propagation and doses of biofertilizer, showing positive responses, especially for Zn at the maximum dose. Propagation by whole rhizome and doses from 600 to 1200 mL per plant week-1 are recommended to obtain the best nutritional results in arrowroot.

“…The concentration of nutrients in the plant and the grain, oil and protein yields are directly correlated, as nutrients are inputs for obtaining these products by the plant. This source-sink relationship, in addition to the direct effect on productive aspects, also influences vegetative growth (Kirkby et al 2022).…”

In plants, several chemical elements are found in different concentrations and formulations. Some of these elements influence each other, either through positive stimulation or inhibition. This study evaluated the correlation between nutrient contents and production components of Jatropha (Jatropha curcas L.). The experiment was conducted at the Federal University of Viçosa-MG, Brazil. A randomized block design with four replications was used. The treatments consisted of six Jatropha clones transplanted 4.5 years ago, from the municipalities of Janaúba and Bomfim, in Minas Gerais, Brazil. Yield was determined by harvesting the ripe and dried fruits, and the oil and protein contents in the grains were obtained by nuclear magnetic resonance. To determine nutrient contents, leaves were collected when the plants were in flowering, with yellow fruits and when the fruits were dry. There was a significant and negative association between grain yield and Mg content. Regarding foliar nutrient contents, the positive (r) significant correlations were between the following pairs: (N and S, r=0.554); (N and Cu, r=0.460); (P and Ca, r=0.420); (K and Zn, r=0.511); (K and Cu, r=0.506); (Ca and Mg, r=0.603); (Zn and Fe, r=0.662); (Zn and Mn, r=0.795); (Zn and Cu, r=0.574); (Fe and Mn, r=0.528) and (Mn and Cu, r=0.479); and the negative ones were between: (K and Ca, r=-0.596); (K and Mg, r=-0.673); (Mg and Cu, r=-0.506). Therefore, it was possible to prove the existence of nutritional interaction between some elements, as well as the effects on grain yields. This research will serve as a basis for studies to recommend fertilizer doses, plant improvement through nutritional efficiency, and studies in the area of biochemistry.
