EFFECT OF DIFFERENT ZINC AND BORON APPLICATION METHODS ON LEAF NITROGEN, PHOSPHORUS AND POTASSIUM CONCENTRATIONS IN MAIZE GROWN ON ZINC AND BORON DEFICIENT CALCAREOUS SOILS (Pages : 1 - 10)

Analysis of nutrient concentrations in plant tissue at certain critical growth stages has often been used as an effective tool to diagnose nutrient disorder problems in field crop production. Two studies on the response of maize (Zea mays L.) to Zn and B applications were carried out on soils in the region of the Fars province of Iran during 2009-2010 growing seasons. Results revealed that the mean N and K concentrations in the leaf were below the critical level but P concentration was sufficient for corn. There was a synergism between Zn-P and between B-K and an antagonism between B-P. The presence of a high amount of B in the soil assisted to increasing of leaf P content by Zn application. With increasing of Zn content, the higher rate of B was needed for increasing K concentration in the leaf by B application. Download
