In a pot trial peanut c.v. Giza 4 seeds were grown in sandy soil. Plants received 8.4 gm per pot (500 kg/fed.) at flowering stage or at onset of pod formation or the amount was divided into two parts and applied at both times. Plants of each gypsum application treatment were sprayed twice with either (NH4)2 MO4 or ZNSO4 at both tested stages. Applying gypsum either at onset or splitting its amount at both tested times significantly increased number of pods and weight of both pods and kernels/pant. Protein percentage in kernels was increased due to applying gypsum at pod formation stage, whereas oil percentage was not affected. Plants which were sprayed with Zn surpassed those sprayed with Mo in number of pods, weight of pods, straw and kernels per plant. There were no significant differences between the effect of Zn and Mo in increasing protein and oil contents in kernels.
