“…A similar increase in the biomass (by 38%) of different maize cultivars with P fertilization was observed by Bukvić et al. (), however, it should be noted that the overall plant biomass per pot may not represent field conditions.…”

To overcome soil nutrient limitation, many plants have developed complex nutrient acquisition strategies including altering root morphology, root hair formation or colonization by arbuscular mycorrhizal fungi (AMF). The interactions of these strategies and their plasticity are, however, affected by soil nutrient status throughout plant growth. Such plasticity is decisive for plant phosphorus (P) acquisition in P‐limited soils. We investigated the P acquisition strategies and their plasticity of two maize genotypes characterized by the presence or absence of root hairs. We hypothesized that in the absence of root hairs plant growth is facilitated by traits with complementary functions, e.g., by higher root mycorrhizal colonization. This dependence on complementary traits will decrease in P fertilized soils. At early growth stages, root hairs are of little benefit for nutrient uptake. Regardless of the presence or absence of root hairs, plants produced average root biomass of 0.14 g per plant and exhibited 23% root mycorrhizal colonization. At later growth stages of maize, contrasting mechanisms with functional complementarity explained similar plant biomass production under P limitation: the presence of root hairs versus higher root mycorrhizal colonization (67%) favored by increased fine root diameter in absence of root hairs. P fertilization decreased the dependence of plant on specific root traits for nutrient acquisition. Through root trait plasticity, plants can minimize trade‐offs for developing and maintaining functional traits, while increasing the benefit in terms of nutrient acquisition and plant growth. The present study highlights the plasticity of functional root traits for efficient nutrient acquisition strategies in agricultural systems with low nutrient availability.

“…Maximum phosphorous content (0.24%) was obtained by application of biological fertilizer + 50 kg ha -1 P 2 O 5 and foliar application of micronutrients which, was 25% higher as compared to control treatment (no fertilizer) (Table 5). Phosphorus uptake by plant decreased by increasing Zn in the soil, but Zn application by foliar application increased phosphorus absorption of soil by plants (Bukvic et al 2003). Phosphate-solubilizing microorganisms had important role in phosphorus solubility and uptake.…”

Field experiment was conducted at Kerman Agricultural and Natural Resources Research Centre (Iran) during [2008][2009] to evaluate the effect of bio-fertilizer, phosphorus and foliar application of micronutrients on dry matter accumulation, yield, and phosphorus and zinc concentration of maize (Zea mays L.). A split plot experiment based on randomized complete blocks design (RCBD) with four replications was followed in the study. The micronutrients foliar application in two levels (foliar application and non foliar application) were the main plots, and four levels of phosphate (T 1 : 0 (no fertilizer), T 2 : 100 kg ha -1 P 2 O 5 , T 3 : 100g bio-phosphate, T 4 : 100g bio-phosphate with 50 kg ha -1 P 2 O 5 ) as the sub plots. Results showed that micronutrients foliar application and biological and chemical phosphorus fertilizers had a significant influence on dry matter accumulation. The maximum dry matter accumulation was obtained by applying 50 kg/ha P 2 O 5 plus bio-fertilizer. Grain yield, 1000-seed weight and protein content of grain were significantly affected by micronutrients and phosphorus fertilizers treatments. Micronutrients foliar application and phosphorus fertilizers interaction had no significantly effect on grain yield, 1000-seed weight and grain protein content. Grain phosphorus and zinc concentration where significantly increased by application of micronutrients and phosphorus fertilizers.

“…Therefore, when Zn fertilization is used, crop productivity usually increases. This has been demonstrated for a variety of crops, in particular for maize (Zea mays L.) (Bukvic et al, 2003;Potarzycki and Grzebisz, 2009;Galavi et al, 2011;Wang et al, 2012).…”

Zinc (Zn) is an essential microelement involved in several plant physiological processes. Therefore, it is important to identify Zn deficiencies promptly--before extensive damage occurs to the plant. The diagnostic tools that are used to identify Zn deficiencies are very important in areas where Zn deficiencies occur. Such diagnostic tools are vital for nutritional management and fertilizer recommendations. The current study investigated the effects of Zn deficiency on maize plants by recording a number of physiological and anatomical parameters. A Zn omission trial (from 0 to 22 days) was carried out to produce plants that had varying degrees of Zn deficiency. Typical symptoms of Zn deficiency (e.g. chlorotic stripes and purple shades on the edges and leaf sheath) appeared 16 days after the omission of Zn from nutrient solutions. As the time of Zn omission increased, there were significant decreases in net photosynthesis, stomatal conductance, maximal efficiency of photosystem I (evaluated by Fv/Fm), biomass (dry weight) and Zn concentrations in plants. Zinc-deficient plants also had a lower vascular bundle proportion coupled with a higher stomata density. These physiological and anatomical changes negatively impacted plant growth. Moreover, they occurred before visible symptoms of Zn deficiency were observed. Zinc concentrations were recorded for younger leaves, rather than for more mature leaves, which is usually recommended for plant analysis. The results demonstrate that the analysis of Zn in young leaves of maize is a very sensitive indicator of Zn status.
