Two field experiments were conducted al EI-Mehala El-Kobra Center,
Gharbla Governorate. Egypt during the two summer seasons of 2000 and 2001. ThIs
Investigation was aimed to study the effect of plant distribution treatments and
microelements foliar spraying on yield and its components as well ~s simple
correlation coefficients of soybean seed yield and its attributes of cv. Giz~ 35. The
experiments were included six planl distrlbu1lons and seven treat!J1ents of
microelements foli~r application. A strip plot design with four replicates was used. The
main findings ooUd be summarized as follows: The tested plant distribution treatments mar1tedty caused significant
differences In all stud~d yield rand Its component characters in bOth seasons. The
resuHs showed that sown soybean plants in arrangements that approach uniformity on
two sides of the ridge, 10 em between hi!l6 and leaving one pl;wn per hln (04)
produced the highest numbers of pOds I plant. seed yield I plant, seed ~nd straw
yields (tlfed) In both seasons. The highest averages of 100-seed we\ght and oil yield
(Kglfed) were produced from sown on two $Ides of the ridge. 10 Of 20 em between
hills and leaving one or two plants per hill, respectively. Mfcroelements fOliar applications dearly showed a signiftcant effect for all
studied yield and its component characters in both seasons. The results showed that
feliar spraying with the combination of Mn + "'10 and lor the combination of Zt1 + Mo al
concentrations of 100 and 50 ppm, respedively signmcantly produced hig est pods
number per plant, 100-seed weight, seed yield! plant. seed and oil yields per feddan.
Maximum straw yield per feddan was produced from spraying with the combination of
Mn + Mo at cOfIcentrations of 100 and 50 ppm, respectively. The highest seed and oil yields (tlfed) were obtained from the Interaction
between planting on two sides of the f'ldge. 10 or 20 em between hills and Ie ving one
or two plants per hill. respectively with torrar application the combination of 1'.4 + 1'.40 at
concentrations of 100 and 50 ppm. respectively in both seasons. There is a pOsitive and significant correlation among seed yield( fed and
ead'l of leaf area Index. number of branches per pian', number of pods per Plant. 100-
seed weight and seed yield! plan!. In general, II can be concluded that for maximil.ing seed and OIl yields per
unil area or soybean could be achieved by distribution plants In arrangements that
approach uniformity by sown on Ute two ridge si~. 10 or 20 an between hills and
leaving one or two plants per hm wfth foliar spraying the combination of Mn + fv'O Of Zn
