  • Influence of crop density and fertilization on corn yield and higher efficienty in milk production = Vpliv gostote pridelka in gnojenja koruze na višji pridelek koruze in višjo učinkovitost mlečne proizvodnje

    The investigations were carried out at the experimental plot of the Faculty of Agriculture Osijek and Production unit in Vinkovci during 1993 and 1994. Hybrid Bc 592 was used for the investigation. ... Stands were arranged with space within rows (for S1-48 000 plants ha-1=29.7 cm, S2-60 000 plants ha-1=23.8 cm and S3-80 000 plants ha-1=17.9 cm) and between rows 70 cm. Three nitrogen fertilisations were applied (N1=90, N2=180 and N3=270 kg ha-1) with 100 kg ha-1 P2O5 and 150 kg ha-1 K2O. Foliar treatments by mixture INA-Fertina K1 in 3 % concentration was carried out twice each year in intensive corn growth phase on one part of the experiment. On the basis of corn grain chemical analysis (concentration of main nutritives and water) carried out in 1993 and 1994 it is shown that increased nitrogen fertilisation in the second and third group had positive influence on protein share increase.The highest energy value was achieved in the third group by conversion of different corn yield of some groups into energy value expressed in FU. Namely it was by 723 FU higher than the first group and by 422 FU higher than the second one. This different corn energy value in groups was conversed into amount of one finished animal product-milk as well as its market realisation and the following values were obtained: more milk (by 654 kg i.e.1.572 kg) was produced in the second and third group than in the first group which financially means 1.635 kn i.e.3.929 kn more than the first one. Similar results as with corn in 1993 were achieved by corn conversion of some groups (1994) into energy value.
