“…Mauad et al (2013) em um estudo sobre o acúmulo de silício na parte aérea de cultivares de arroz de terras altas com adubação foliar aponta que o nutriente se acumula mais à planta a partir do perfilhamento, promovendo, portanto, um maior número de perfilhos à planta de arroz. Kheyri et al (2018), em um estudo realizado no Irã, referente ao efeito de diferentes recursos e métodos de aplicação de silício nas características agronômicas do arroz identificaram que a aplicação de silício via foliar aumentou de forma significativa o número de perfilhos férteis.…”

“…No estudo de Kheyri et al (2018), identificou-se que a aplicação de silício via foliar embora não tenha promovido diferença significativa na altura das plantas, influenciou diretamente no comprimento da panícula, sendo, portanto, um nutriente considerável à promoção de melhoria das características das plantas de arroz.…”

Effects of Silicon and Zinc Sources on Quantitative and Qualitative Characteristics of Canola at Normal and Late Planting Dates

“…The reason for increasing seed yield by silicon fertilizers application, especially in the form of nanoparticles can be related to increasing yield attributes and improving nutrients uptake in rapeseed. Kheyri et al (2019b) attributed the increase in rice grain yield by Si application to the nutrients availability and the improvement of their absorption and transport to the grains. Silicon affects crop yield through sedimentation in leaves, increasing leaf resistance, increasing chlorophyll content on leaf surface and subsequently improving light absorption by plants (Saadatmand and Enteshari, 2013).…”

“…Improvement of grain Si concentration by foliar spray of silicon nanoparticles in other crops such as rice (Kheyri et al, 2019a) has been reported. Simultaneous application of zinc and silicon via either soil application or foliar spray improves the Si concentration and uptake in the plant due to synergistic interaction between these two elements (Kheyri et al, 2019b). Sohail et al (2020…”

“…Application of nutrients by foliar application method increases yield and reduces the use of chemical fertilizers by soil application method (Bhuyan et al, 2012). Kheyri et al (2018) reported that the foliar application of nanoparticles is superior to the soil application of elements due to the small diameter of nanoparticles and better uptake of elements by the plant. Silicon nonafertilizers are easily permeable to the leaves and form a thick silicate layer on the leaf surface (Meena et al, 2014).…”
