Sažetak
Nine mother parents of maize hybrid (B1=♀2-48 ; B2=♀1767/99 ; B3=♀ 87-24 ; B4=♀135-88, B5=♀84- 28 ; B6=♀84-44 ; B7=♀438-95 ; B8=♀30-8 ; B9=♀B- 73) were grown under field conditions on Podgorac acid soil in Osijek-Baranya County for two growing seasons (2006 and 2007). Total 36 rows of each genotype were sown by pneumatic sowing machine (distance in row 19.5 cm and interrow spacing 70 cm). Distribution two rows of the genotypes was by order from B1 to B9 from the central line of trial toward left and right margins. Maize rows in the early growth stage were divided in four sub-plots (replicates: basic plot 14.0 m2 or two 10-m rows). The ear-leaves at flowering and grain at maturity were taken from each basic plot for chemical analysis (ICP-OES procedure). Average concentrations (2-year means: g kg-1 in dry matter) were as follows: 3.21 and 3.00 (P), 20.8 and 3.45 (K), 6.60 and 0.05 (Ca), 2.44 and 1.04 (Mg). for leaves and grain, respectively. Differences among genotypes were from 2.69 to 3.95 and from 2.70 to 3.57 (P), from 18.0 to 23.3 and from 3.03 to 3.71 (K), from 5.45 to 8.02 and from 0.04 to 0.07 (Ca), from 1.35 to 3.09 and from 0.84 to 1.36 (Mg), for leaves and grain respectively. Specifities of leaf composition of individual genotypes were as follows: B1 (the highest Ca and Mg), B2 (the highest P), B4 (the lowest Ca, Mg and P), B6 (the highest K) and B7 (the lowest K). Grain composition was mainly in accordance with specifities of leaf compostion.
