Abstract: Zinc deficiency usually occurs in maize grown in Brazilian acidic soils. The aim of this study was to evaluate commercial maize cultivars for their Zn uptake and utilization efficiency. A greenhouse experiment using nutrient solution with young plants was carried out at Campinas, State of São Paulo, Brazil, in 2002. Treatments consisted of: 0.0; 0.1; 0.2; 0.4 and 0.8 mg L -1 Zn in the main plots and 24 commercial maize cultivars in the subplots, in a randomized complete block design. Zn concentration in shoot … Show more

“…Such an increment in brown rice Zn concentration might be attributed to enhanced Zn concentration in soil solution as well as in plant aerial parts that was transferred to grains. This is in accordance to previous studies, which concluded that increased Zn application significantly increases its concentration in the edible plant parts of staple food crops (Furlani et al 2005;Wu and Zhang 2002;Kanwal et al 2010;Fahad et al 2015b). Foliar application of ZnSO 4 at panicle initiation stage recorded higher brown rice Zn concentration than soil-applied ZnSO 4 or foliar application at milky stage in all cultivars suggesting that foliar application at panicle stage is most effective for Zn biofortification in rice.…”

“…In fact, plant physiological and genetic components affect uptake and utilization of nutrients under many ecological and environmental surroundings (Baligar et al, 2001). The nutrient utilization efficiency for the shoot dry matter decreased with increasing nutrient supply to roots (Furlani et al, 2005). In present study, Zn utilization efficiency of all the tested maize cultivars was highest for individual applied nutrients (Fig.…”

“…Among cultivars, DK-6142 had highest Zn as well as P utilization efficiency as compared to all other cultivars. According to Furlani et al (2005), genetic make up for different varieties have their different nutrient utilization efficiency. Fageria et al (2008) demonstrated that higher Zn utilization efficiencies of cereals were found as compared to legumes and these are associated with higher grain yields of maize.…”

“…In this work, the authors attributed this behavior to the soil Zn levels that were adequate and the parameters that indicate the quality of soil as adequate organic matter and absence of compression. Furlani et al (2005) evaluated 24 commercial maize hybrids for the efficiency in absorbing Zn doses ranging from 0.0 to 0.8 mg L -1 of nutrient solution in a greenhouse of young plants, evidenced by the increase in the Zn concentration in the air part of the maize plant, biometric variables, height of dry plants and dry mass of the aerial part, increased linearly with the doses.…”
