Interaction Between Resistance Inducer and Micronutrients on the Control of Root-Lesion Nematode and the Development of Soybean Plants

et al. 2020

Root lesion nematodes limit the productivity of several crops of economic importance, requiring alternatives for their management. Resistance inducers activate enzymes involved in defense mechanisms and micronutrients can influence this process by acting as enzymatic cofactors. Thus, the objective of this study was to evaluate the effect of foliar application of a commercial organomineral fertilizer and its association or not with zinc (Zn) and manganese (Mn) micronutrients on the Pratylenchus brachyurus suppression and soybean plant development under greenhouse conditions. Shoots of soybean were treated 10 days after germination and inoculated with 5000 nematodes/plant five days after the treatments, using untreated plants as controls. Treatments consisted of a commercial product based on phosphorylated mannanoligosaccharide derived from the cell wall of Saccharomyces cerevisiae (here coded as MOS), Zn, Mn, MOS+Zn, MOS+Mn or MOS+Zn+Mn. At sixty days after establishment of treatments, the plants were collected and evaluated for vegetative analysis, nematological analysis and nutrient contents. The work was repeated at different times: experiment 1 from November 2016 to January 2017 and experiment 2 from October to November 2017. All treatments were efficient in controlling P. brachyurus in at least one of the evaluated nematological parameters, compared to the control. However, only the plant spraying with MOS+Zn results in significative reduction of the total number of nematodes and the number of P. brachyurus nematodes per gram of soybean root in both experiments. In addition, spraying of plants with Mn increased shoot dry weight and all treatments resulted in higher concentrations of copper, Zn and Mn in soybeans leaves compared to control.

“…In a study by Oliveira et al (2017) they observed that Zn application promoted increase in plant height, shoot dry mass and soybean root mass, with the highest averages observed for the higher doses of Zn. The results also corroborate the present study (Table 5).…”

“…In soybean cultivated in soil from the Cerrado region of Brazil, Oliveira et al (2017) observed that the application of Zn via soil (0, 3, 6, 9 and 12 kg ha -1 of Zn) during phenological stage V9 (eighth fully developed trifoliate leaf) linearly increased leaf Zn concentration, thousand grain mass and grain yield.…”

Nutrition, yield and nutrient export in common bean under zinc fertilization in no-till system

et al. 2020

Zinc (Zn) is one of the most deficient plant micronutrients in agricultural crops. The objective of this study was to evaluate plant nutrition, grain yield and nutrient export rate in response to soil and foliar Zn fertilization in common bean (Phaseolus vulgaris L.). Two field experiments in no-till system were carried out using two common bean cultivars, BRS Esteio (black bean) and IPR Campos Gerais (Carioca bean). Treatments were composed of soil Zn application during sowing and foliar Zn spray at flowering stage. Soil Zn application had effect on leaf Zn concentration in IPR Campos Gerais and did not affect grain yield of both cultivars. Foliar Zn spray increased leaf Zn concentration by approximately two times in both cultivars, but negatively affected the grain yield in BRS Esteio. Leaf concentration of N, Ca and S were affected by soil Zn application and leaf concentration of Mn was affected by foliar Zn spray, while leaf concentration of P, K, Mg, Cu and Fe were not influenced by the soil and foliar Zn treatments. In treatments without Zn, the descending order of nutrient export rate from the experimental site was as follows: N > K > P > Ca ≈ S > Mg for macronutrients and Fe > Mn > Cu > Zn for micronutrients. Foliar Zn spray increased the export rate of Zn, P, Ca, Mg, S, Mn, Cu and Fe in IPR Campos Gerais, while soil Zn application resulted in higher export rate of P, K and Mn in BRS Esteio.

Por outro lado, Oliveira et al (2017) recomendaram a adubação de Zn via solo para a cultura da soja, uma vez que os resultados da adubação afetaram positivamente o teor foliar deste micronutriente, a altura de plantas, número de vagens, nós reprodutivos, diâmetro de caule e a massa de 1000 grãos.…”

It is estimated that 17.3% of the world population is at risk for Zn deficiency, and annually, about half a million children under five years of age die from causes related to Zn malnutrition. Low-cost strategy to increase Zn intake by humans is to increase the consumption of biofortified crops. Biofortification comprises the process for increasing contents of one or more nutrients in the edible parts of agricultural crops in order to increase their nutritional value. For biofortification to reach one billion people by 2030, mutual efforts must be added. Among them, policies must place more emphasis on agriculture role in improving health. Governments and institutions must include biofortification on food security policy, and food processors and others responsible for production chain must include biofortified crops in their product lines. The objective of this study was to carry out a bibliographic review to elucidate the dynamics of Zn in soil, the essential function of Zn in plant yield, the plant role in transfer Zn to human body, the importance of Zn in the human health and current measures that have been taken to mitigate Zn malnutrition in the world.
