Agronomic biofortification and nutrient uptake of sorghum (Sorghum biochor L.) as influenced by fertilization strategies

Abstract

The micronutrient required in minute quantity and their deficiency leads to diminished growth and yield of crops. The field experiment was carried out at College Farm, Rajendranagar during rabi 2015-16 with factorial randomized block design with two factors sorghum genotypes and zinc levels. Findings revealed that varieties and fertilization spray had significant on zinc concentration and uptake by grain and stover of sorghum. Variety CSV -31 (V2) and soil application of zinc sulphate @ 50 kg ha -1 + foliar spray of ZnSO4 @ 0.2% at knee high stage and at flowering (F5) gave significantly highest zinc concentration and uptake by grain and stover in comparison to their respective treatments.

Agronomic bio-fortification of iron, zinc and selenium enhance growth, quality and uptake of different sorghum accessions

“…The increase in these traits of particular accessions might be due to its genetic makeup where the basal and foliar application of Zn, Fe and Se imparts significant effects on plant height and stem diameter of sorghum. The response of different sorghum genotypes to Zn application also varied in previous studies (Markole et al 2020). However, among the treatments, Se recorded the maximum plant height, and stem diameter may be due to timely availability and efficient utilisation of Se and other nutrients (Witold et al 2008) that improved the catalytic action in plant and also resulted in early plant maturity.…”

Agronomic biofortification of zinc in different rice genotypes

“…This result was confirmed by the findings of Yuan et al (2013) [10] . There was a difference in grain Zn concentration among the genotypes and this may be due to the difference in loading ability of Zn from the panicle tissues to the grains (Markole et al, 2020) [11] .…”
