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.
