Effect Of Foliar Application Of Urea And Ammonium Nitrate On The Dry Weight And Protein Content Of Maize Plants, Alvaro Fiallos
Effect Of Foliar Application Of Urea And Ammonium Nitrate On The Dry Weight And Protein Content Of Maize Plants, Alvaro Fiallos
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Urea and ammonium nitrate were applied to leaves of maize plants growing in growth chambers on nutrient solutions containing three different concentrations of ammonium nitrate. Dry weights, and the soluble protein contents of leaves, sterns and roots we remeasured.
Both urea and ammonium nitrate did increase the dry weights of leaves and stems when ammonium nitrate was used in the nutrient solutions (0.5 and 2.5 mM/ liter). When nitrogen was not used in the nutrient solutions, no increments of dry weight occurred. The protein contents of leaves were increased for plants in the same nutrient solutions that produced increases in …
