Technical Abstract: The effects of four fertilizer treatments on yield, plant growth parameters, and leaf elemental micronutrient content of 'Malabar' spinach (Basella alba L.) were evaluated in a Ruston fine sandy loam soil (fine-loamy, siliceous, thermic Typic Paleudult) at the USDA Small Fruits Research Station in Poplarville, MS. Fertilizer (13-6-11) treatments consisted of (1)112 kg/ha applied twice during the season (June and August) for a total of 224 kg/ha, (2)112 kg/ha applied 4 times during the season (June, July, August, September) for a total of 448 kg/ha, (3) 224 kg/ha applied twice for a total of 448 kg/ha, and (4) 224 kg/ha applied 4 times for a total of 896 kg/ha. Plant growth was positively correlated with total N applied regardless of application timing. Leaf yield followed the same pattern as total plant growth, except frequent N applications was as important as total applied N. Leaf size was smallest with the 224 kg/ha per year N fertilization rate. Nitrogen rates of 448 to 896 kg/ha per year did not result in different leaf size regardless of the number of applications. Leaf Fe concentrations were decreased as levels of N fertilizations were increased. Similar trend was also observed for B concentrations in leaves. N fertilization rates had no effect on leaf concentration of Mn, Zn, and Cu.
