Abstract

Two field experiments were carried out at the Agricultural Production and Research Station, National Research Centre, Nubaria Province, Behaira Governorate, Egypt, during the two successive summer seasons of 2012 and 2013 to investigate the effect of combination between potassium fertilizer levels and zinc foliar application on growth, yield, yield attributes and some chemical constituents of groundnut. The results clear that different treatments show significant differences in both growth samples however, 90 K2O kg/ha +1000 mg/L Zn surpassed in most studied characters with no significant difference between this treatment and treatment 90 K2O kg/ha+500mg/L Zn in most studied characters, except stems dry weight/plant in both samples. Increasing foliar zinc application from 0 to 1000mg/L significantly increased all yield and yield attributes with the potassium fertilizer levels however, the treatment 90 K2O kg/ha +1000 mg/L Zn records the highest values of studied character. Significant differences between treatments in seed protein content, NPK seed and straw concentration.
