Effect of foliar application of iron and zinc on nutrient uptake and grain yield of wheat under different irrigation regimes

Abstract

A field experiment was carried out to study the zinc-iron relationship in wheat (BARI Gom-26) plant grown under water stress condition in the field near net house of Soil Science Division, BARI, Joydebpur, Gazipur, during November 2015 to March 2016. The experiment was designed in a split plot on sixteen treatments comprising four irrigation treatments (regular irrigation, stopping irrigation at crown root initiation, stopping irrigation at booting stage and stopping irrigation at grain filling stage) and four foliar application of zinc and iron (control, 0.05% of zinc, 0.05% of iron and 0.05% of zinc +0.05% of iron). Zinc sulphate monohydrate (ZnSO4. H2O) and ferrous sulphate (FeSO4. H2O) were used as a source of Zn and Fe. The highest yield (4.01 t ha-1) was recorded in stopping irrigation at grain filling stage which was identical with regular irrigation. Water stress at crown root initiation stage had the most negative effect on growth and yield. Foliar application of zinc and iron played a major role on yield and yield components of wheat at later stages of growth. The results obtained from the present research showed that iron and zinc spray increased grain yield and quality of wheat and improved the effects caused by drought stress.Bangladesh J. Agril.

Effects of Foliar Application of Liquid Fertilizer on Agronomical and Physiological Traits of Rice (Oryza sativa L.)

“…It seems that the number of filled grains panicle, number of tillers per plant, and plant dry matter play an important role in determining the 1,000-grain weight of rice. Although we did not find significant differences in the mean 1,000-grain weights of rice plants in different treatments in our study, some previous studies reported significant effects of foliar nutrient application on 1,000grain weight (Khursheed et al, 2018;Shaygany et al, 2012;Sultana et al, 2018). However, some other studies also did not find significant effects of foliar application of nutrients on 1,000-grain weight (Begum et al, 2003;Farooq et al, 2018).…”

“…After this stage, accumulation of nutrients is intensified, and reaches a maximum 45-65 days after planting, such that the highest rate of N absorption in these varieties is observed 65 days after planting (Crusciol et al, 2016). Other researchers have also reported significant effects of foliar nutrient application on rice plant height (Deswal & Pandurangam, 2018;Sultana et al, 2018). Shaygany et al (2012) reported that foliar application of macro-and micronutrients at transplanting, tillering, and panicle initiation stages affected the number of tillers per rice plant.…”

“…The amount of dry matter is critical to the grain yield, and the availability of sufficient dry matter is crucial to obtaining high grain yields (Song et al, 2013). Previous studies also reported significant effects of foliar application of nutrients on grain yields (Khursheed et al, 2018;Singh et al, 2014;Sultana et al, 2018).…”

Grain yield and quality of wheat are improved through post-flowering foliar application of zinc and 6- benzylaminopurine under water deficit condition

“…However, there is some evidences that indicate up regulation of this gene has also caused increased yield in rice. Several investigators ( Ma et al., 2017 ; Sultana et al., 2018 ; Pavia et al., 2019 ; Ullah et al., 2019 ; Ashkiani et al., 2020 ; Sattar et al., 2022 ) have studied the role of Zn in improvement of drought tolerance in wheat. Lower CKX gene expression in developing seeds might to because foliar applied Zn could, to some extent, mitigate the adverse effect of the imposed drought.…”

“…(2022) in drought induced wheat. In addition, it was reported that the foliar application of zinc increased grain yield and quality of wheat under drought stress condition ( Sultana et al., 2018 ).…”
