INTERRELATIONS OF NITROGEN, IRON AND ZINC IN THE GROWTH OF THREE SORGHUM VARIETIES
Abstract
Iron and zinc deficiencies are serious problems of crop production in the states west of the Missouri river. Iron and zinc deficiencies have been observed in crops growing on western Nebraska so118. These soils are generally neutral to alkaline in reaction and many are calcareous. Micro- nutrient deficiencies are common in areas where the subsoil is exposed through erosion or land grading. These areas are also deficient in nitrogen due to the loss of organic matter..Nitrogen, iron and zinc play vital biological roles and are essential for normal plant growth and reproduction. Iron and zine participate in activating or function as a part of enzymes that enter metabollic pathways leading to protein synthesis. Nitrogen is a major constituent of proteins and precursor of nucleic acids, nucleotides and nucleosides.While nutrients are important for their individual effects on plant growth, there are important interrelations of major and micronutrients that influence the effectiveness of the individual nutrients urned. These interrelation- ships are not necessarily the same for all species of plants and may differ with the genotypes of a given species. An investigation was conducted to study the interrelations of nitrogen, iron and zine on the growth of sorghum on a Tripp very fine sandy loam subsoil as influenced by genetic factors.
