“…Manganese increased seed oil content but had little impact on grain protein percentage. These results are in agreement with Hebbern et al (2005), Mirzapour and Khoshgoftar (2006), Sarkar et al (2007) and Movahhedy-Dehnavy et al (2009). Also, iron used up to 25 kg haG increased oil and protein content in soybean 1 seed but in excess amounts of iron these traits were decreased, however, this reduction was not statistically significant.…”

In order to investigate the relationships between oil percent, protein percent, pod, seed and total dry weight in soybean with zinc, iron and manganese applications, two field experiments were performed at the research field of the Islamic Azad University of Kermanshah, Iran in 2010-2011. The experimental design was a factorial experiment based on randomized complete block with three replicates. Treatments includes: Three level of Zn (0, 20 and 40 kg haG), Fe 1 (0, 25 and 50 kg haG) and Mn (0, 20 and 40 kg haG). At the harvesting time, ten plants were 1 1 randomly selected from each plot and grains were separated from pods. Oil and protein percent in soybean seed were measured. For the measurement of pod, seed and total dry weight the samples were dried and finally were weighed. The results indicated that zinc and iron had significant effects on all of evaluated traits (p<0.01). Manganese had significant effects on oil, pod, seed and total dry weight (p<0.01) and on protein (p<0.05). Application of 20 kg Zn haG had the most impact on pod 1 dry weight and plant dry weight, while maximum oil and protein contents and seed dry weight were recorded with 40 kg Zn haG. In excess amounts of iron application the oil and protein content 1 was reduced, although was not statistically significant. The effect of zinc and manganese applications on oil percent in soybean seed was more than protein content.

“…Our understanding of the factors that determine the ultimate efficacy of foliar applications remains poor and the response of plants to foliar Zn applications is highly variable (Fernández and Brown, 2013). Many reports indicate that foliar application of Zn may significantly increase the concentrations of Zn in the applied leaves but may have little effect on foliar concentrations in non-sprayed tissues or tissue that develop subsequent to the foliar application (Zhang and Brown, 1999; Mirzapour and Khoshgoftar, 2006; Sanchez et al, 2006). The factors that control the uptake and subsequent translocation of foliar applied nutrients out of the leaf, and the effect of spray formulation on these processes are poorly understood (Bukovac, 1985; Adamec, 2013; Fernández and Brown, 2013).…”

Enhancing nutrient uptake and the subsequent elemental transport from the sites of application to sites of utilization is of great importance to the science and practical field application of foliar fertilizers. The aim of this study was to investigate the mobility of various foliar applied zinc (Zn) formulations in sunflower (Helianthus annuus L.) and to evaluate the effects of the addition of an organic biostimulant on phloem loading and elemental mobility. This was achieved by application of foliar formulations to the blade of sunflower (H. annuus L.) and high-resolution elemental imaging with micro X-ray fluorescence (μ-XRF) to visualize Zn within the vascular system of the leaf petiole. Although no significant increase of total Zn in petioles was determined by inductively-coupled plasma mass-spectrometer, μ-XRF elemental imaging showed a clear enrichment of Zn in the vascular tissues within the sunflower petioles treated with foliar fertilizers containing Zn. The concentration of Zn in the vascular of sunflower petioles was increased when Zn was applied with other microelements with EDTA (commercial product Kick-Off) as compared with an equimolar concentration of ZnSO4 alone. The addition of macronutrients N, P, K (commercial product CleanStart) to the Kick-Off Zn fertilizer, further increased vascular system Zn concentrations while the addition of the microbially derived organic biostimulant “GroZyme” resulted in a remarkable enhancement of Zn concentrations in the petiole vascular system. The study provides direct visualized evidence for phloem transport of foliar applied Zn out of sites of application in plants by using μ-XRF technique, and suggests that the formulation of the foliar applied Zn and the addition of the organic biostimulant GroZyme increases the mobility of Zn following its absorption by the leaf of sunflower.

“…Irrespective of the rice grain, nearly half of the cerealgrowing areas of the world are Zn deficient (Cakmak 2002). The most critical conditions are in arid and semiarid regions, where soil organic matter content is low while pH and CaCO 3 content in soils are high (Mirzapour and Khoshgoftar 2006). Zinc deficiency affects one third of the world's population.…”

Zinc (Zn) is an important micronutrient for the physiology of plants. It is poorly available to the plants in soil solution. A pot experiment was conducted to evaluate effectiveness of various Zn application methods on key enzyme activities and protein content of two contrasting rice genotypes viz., PD16 (Zn efficient) and NDR359 (Zn inefficient). The treatments were, control (0 mg Zn kg Among all the methods tested soil+foliar application of Zn fertilizers was found most effective in increasing superoxide dismutase (SOD) and carbonic anhydrase (CA) activities as well as chlorophyll and protein content in both the rice varieties. NDR359, showed higher enzyme activities and more chlorophyll content in leaves than PD16, when Zn was applied either through foliar spray alone or in soil along with foliar application. Regarding the protein content in grains, PD16 showed higher protein content than NDR359, thus showed better translocation of Zn from leaves to grains.
