Fertilization whit zinc, copper and chlorine in the wheat crop in the southeast of Buenos Aires
Nitrogen (N), phosphorus (P), and sulfur (S) fertilization is a common practice in wheat (Triticum aestivum L.) production, however, micronutrients such as zinc (Zn), copper (Cu) and chlorine (Cl) can be deficient in soils and limiting plants metabolic functions in extensive production systems. The aim of this work was to evaluate the effect of Zn, Cu, and Cl fertilization on wheat dry matter accumulation, grain yield and protien content. The experience was carried out in the Agricultural Experimental Station of INTA Balcarce for two years. A full randomized block design was used and the treatments were fertilization with: i) NPS, ii) NPS+Zn+Cu, and iii) NPS+Zn+Cu+Cl. Wheat grain yield was not significantly increased by micronutrients fertilization in either year, with contrasting weather conditions (averaging 4372 kg ha-1 for year 1 and 7441 kg ha-1 for year 2). In years, green index, dry matter, N accumulation during different crop stages and grain protein content were not significantly affected by micronutrient application. It is concluded that Zn, Cu, and Cl fertilization did not differentially affect any wheat parameters evaluated. These results would be a consequence of micronutrients availability, which was above the reported thresholds, which may have decreased the probability of response.
