“…Foliar fertilization, however, is an important tool to supply micronutrients to plants. Pietroski et al (2015) foliar on Panicum maximum cv. Mombasa and reported increasing forage production and nitrogen accumulation, concluding that this is an important complementary practice to soil fertilization.…”

The objective was to determine the structural and nutritive parameters for Panicum maximum cv. BRS Zuri under a Eucalyptus shading system, in rainy and dry seasons. At the beginning of each season, the treatments (foliar fertilization levels of 0, 3, 6 and 9 L ha-1) were applied and evaluated at 28, 56, and 84 growing days. The treatments did not affect significantly (p ≥ 0.05) the evaluated parameters. The systems (shading and full sun) and seasons did not change (p ≥ 0.05) forage and root masses. The leaf crude protein content was higher (p ≤ 0.05) in the dry season. Height, leaf mass, stem and dead material, neutral and acid detergent fiber contents, and in vitro dry matter digestibility were affected (p ≤ 0.05) by the system x season. The growing days did not affect (p ≥ 0.05) forage mass. The mass of dead material decreased (p ≤ 0.05) over the evaluated intervals. The other parameters were affected (p ≤ 0.05) by system × growing days. Based on the results, the forage and root masses show that the cv. BRS Zuri is adapted to the shading in the proposed experimental conditions. These masses added to the crude protein content indicate adaptation to low rainfall, inherent to the dry season, while foliar fertilization applied at the beginning of seasons did not affect the structural and nutritive parameters of BRS Zuri grass.

“…However, most of these works were conducted in established pastures. For example, according to Pietroski et al (2015), in their work with foliar nitrogen fertilization in Mombaça grass (Panicum maximum cv. Mombaça), the foliar application of nitrogen resulted in increased forage production, green color index and N accumulation, therefore, an important complementary practice to nitrogen fertilization of the soil.…”

“…Mombaça), the foliar application of nitrogen resulted in increased forage production, green color index and N accumulation, therefore, an important complementary practice to nitrogen fertilization of the soil. It is important to emphasize that the best soil fertility conditions in the experimental area of the work by Pietroski et al (2015), together with the highest doses of nutrient applied via the foliar (0, 15, 30, 45 and 60 kg ha -1 of N) may have favored the occurrence of positive effects of the foliar fertilizer.…”

A adubação foliar com macro e micro minerais para o estabelecimento de gramíneas forrageiras pode ser uma alternativa menos onerosa ao produtor, contudo os possíveis benefícios dessa técnica de maneja ainda precisam ser melhor estudados. O objetivo deste trabalho foi avaliar as respostas fisiológicas, produtivas, estruturais de gramíneas do gênero, em função da aplicação ou não de adubo foliar durante o estabelecimento das plantas. Quatro experimentos foram conduzidos separadamente e concomitantemente, para avaliar, as seguintes gramíneas forrageiras: Urochloa brizantha cv. Marandu e os capins Mulato II, Mavuno e Ipyporã, híbridos de Urochloa. Os experimentos foram conduzidos de novembro de 2018 a março de 2019, em delineamento inteiramente casualizado, com quatro repetições. A área experimental de cada experimento consistiu de quatro parcelas com 12,25 m², onde metade da área das parcelas recebeu o adubo foliar (FH PASTAGEM FOLIAR, com 14% de N; 12% de P; 12% de K; 0,38 % de Mg; 10,2% de S; 0,24% de Cu; 0,18% de Mn e 0,63% de Zn) e a outra metade, não. O fertilizante foliar (2 kg ha-1) foi diluído em água e aplicado com pulverizador manual aos 42 dias após a emergência das plantas. Foram avaliadas as variáveis respostas: índice spad, índice de área foliar, interceptação de luz pelo dossel, produção de forragem e densidade de raiz. Em todos os experimentos, a aplicação do adubo foliar durante o estabelecimento dos capins Marandu, Mulato II, Mavuno e Ipyporã não influenciou os índices spad e de área foliar, a produção de forragem e a densidade de raiz.

The use of saline water in the production of vegetables is one of the main challenges of producers, since salt stress causes a decrease in crop production and yield. The objective of this study was to evaluate the growth of radish crop cultivated under salinity levels in irrigation water and foliar fertilization. The treatments were obtained from the combination of four electrical conductivities of irrigation water (0.5, 1.5, 3.0, 4.5 dS m-¹) and two forms of foliar fertilization (with foliar fertilization and without foliar fertilization). The experimental design used was completely randomized in a 4 x 2 factorial scheme, with four replications and one plant per plot, totaling 32 experimental units. Radish plants were evaluated for leaf number, plant height, leaf area, relative chlorophyll index, root mass and shoot dry mass. It was found that increasing salinity levels affect the growth and development of radish plants, with significant reduction in leaf emission, leaf area, plant height, SPAD index and phytomass accumulation and that leaf fertilization did not mitigate the effects caused by salinity in irrigation water.
