A field experiment was carried out to study the impact of three rates of
magnesium sulphate (MgS0₄) and Effective Microorganisms each alone or both
together on seed yield and chemical constituents of peanut (c.v. Giza 6) grown on
sandy soils at Ismailia Agric. Res. Station. The treatments were zero, 10 and 20
kg/fed MgS0₄, and diluted effective microorganisms (1 :100) used as foliar application
at the rate of 400Ufed to the soil in two times after 30 and 50 days from cultivation. Results revealed that all the applied rates of MgS04 led to significant
increases in seed yield, pods yield and foliage yield with priority for 20 Kg/fed MgS04.
Moreover, there was a significant increase in seeds uptake of N, P and K. Generally, application of effective microorganisms either alone or together
with MgSO. 20 kg/fed showed a progressive increase in seed yield, with a maximum
value of 1052.8 Kg/fed. In addition, data cleared significant increases for NPK-
uptake in case of effective microorganisms application.
