Efectul tratamentelor foliare cu ingrasaminte si erbicide asupra unor insusiri morfologice si de productivitate la soia

Abstract

Trough major competition for the vegetation factors (water, light and nutrients) the weeds determines the morphological and biological changes on the soybean plants, which bring down the yield. he growing, development and metabolic plants activity was influenced according to climatic condition of the year, effectiveness of the herbicides which was apllied simple or mixed and method of applying fertilizers, on the soil or foliar concomitant with applications. In order to establish the effectiveness for the both of technologically factors: foliar fertilization herbicides applications and this interaction, during 2002-2004 at A.R.D.S. Secuieni-Neamt was located a soybean trial on chernozen soil. The effect of foliar application with mains elements and microelements olone or together with herbicides on morphological and productivity parameters was materialized bysuperior values of all analysed parameters (height plants, foliar surface, number and seeds weight).
