Uptake of Cu, Zn, Fe and Mn by maize in the strip cropping system

Abstract

A field experiment was conducted in 2008-2010 at the Experimental Station of the Faculty of Agricultural Sciences in Zamość (50°42'N, 23°16'E), University of Life Sciences in Lublin. The aim of the study was to assess the impact of cropping method and weed control methods on the content of Cu, Zn, Fe and Mn in maize and on their uptake. Two cropping methods were studied -sole cropping and strip cropping (common bean, dent maize and spring barley in adjacent strips) and two weed control methods -mechanical and chemical. Strip cropping reduced Mn content in maize, did not significantly affect Zn content, and increased accumulation of Cu and Fe. The content and uptake of the elements by maize depended on the position of the row in the strip and on the adjacent plant species. Placement next to beans resulted in higher Fe and Zn content, while placement next to barley increased Cu content. The highest Mn content was noted in maize from the centre row. In general, micronutrient uptake by maize was lowest in the middle row. These results indicate that strip cropping can be an effective agricultural practise for plant biofortification.

Sulphur and Nitrogen Fertilization as a Potential Means of Agronomic Biofortification to Improve the Content and Uptake of Microelements in Spring Wheat Grain DM

“…e most common form of multiple cropping is mixed cropping of cereals, and cereals with legumes. In this system, individual species can exploit different resources or the same resources more efficiently, which can increase total yield per unit area in comparison with the cultivation of a single species [33][34][35].…”

Concentrations and uptake of micronutrients by oat and pea in intercrops in response to N fertilization and sowing ratio

“…Consequently, a facilitation of the mineral nutrition of wheat and chickpea in intercrops has been reported with higher grain concentrations of N, P, K, and Fe in wheat and Mn and Zn in chickpea and higher shoot concentrations of P, K, Fe, Mn, and Zn in wheat and Mn and Zn in chickpea (whereas N, P, and K decreased in chickpea shoots) (Gunes et al, 2007). The positive influence of accompanying plants has also been shown in strip intercropping experiments: a higher concentration of Cu and Fe was observed for maize biomass placed next to bean compared to maize in the centre of the strip that was more distant to bean (but for which a higher Mn concentration was reported) (Głowacka, 2013). Similar to our results, Li et al (2004) observed in wheat-chickpea intercrops higher Zn concentrations in the shoots of both the crops and higher Mn concentrations in the shoots of chickpea.…”

“…Our results showed just effects on pea grain and residue in one year. An enhancement of Fe concentrations has also been observed for peanut leaves intercropped with maize (Zuo et al, 2000), maize intercropped with bean (Głowacka, 2013), and for both species in wheat-chickpea intercrops (Gunes et al, 2007). In an Fe-deficient calcareous sandy soil, Cu, Fe, and Zn concentrations and chlorophyll content of peanut shoots intercropped with gramineous species (barley, oat, maize, or wheat) were much higher than those in monocropped peanut (Zuo and Zhang, 2008).…”

“…For Fe and Mn, there are antagonistic reactions in the uptake of these elements in plants (Tanaka and Navasero, 1966). Consequently, higher Fe but lower Mn concentrations have been observed in intercrops for maize strip cropped with bean (Głowacka, 2013), whereas in maize-peanut intercrops, the shoot concentrations of Fe were increased in peanut but Mn in peanut shoots and Fe and Mn in maize shoots were not affected (Inal et al, 2007). We observed no changes for Mn in grain and residue of oat but higher values in intercropped pea in one year for both Fe and Mn.…”

Marcha de absorção, taxa de acúmulo e exportação de micronutrientes e alumínio pelo tabaco (Nicotiana tabacum L.)

“…A ordem de absorção de micronutrientes pela planta de tabaco seguiu a sequência Fe>Mn>B>Zn>Cu, o mesmo observado para as folhas; e para o caule a ordem foi Fe>Mn>Zn>B>Cu. Segundo MOREIRA et al (2017), para a maioria das gramíneas cultivadas observa-se a sequência de extração Fe>Mn>Zn>B>Cu (NAKAGAWA et al 2009, ZOBIOLE et al 2011, GLOWACKA 2013 e, para as leguminosas, Fe>Zn>B>Mn>Cu (WHALEN et al 2002, TEIXEIRA et al 2008. Em olerícolas também são verificadas maiores extrações de Fe e menores de Cu, com variações entre Mn, Zn e B para cada cultura.…”
