Abstract

Both granulometry and solubility could affect the response of a crop to fertilizer application. The objective of this work was to compare the effect of a commercial source of micronutrients, in granular and powder form, with a mixture of pro analyse products. A completely randomized design, with three products, four replicates and four rates (0, 14, 28 and 56 mg dm-3 of soil) were used. The highest grain yield was due to the commercial product in powder form. Positive correlation was found between plant Zn and its content in the products.
