Selection of maize hybrids with risk examination method
2000
Drimba, P. | Nagy, J. | Sum, O.
By examining the data of our polyfactorial long-term experiment carried out on chernozem soil with lime deposits at the Experimental Farm of Debrecen University of Agricultural Sciences we wanted to find out that of the three given hybrids (A,B,C) which and in what percentage we should grow in order to achieve a certain yield with the possibly lowest yieldrisk. The factors were the following: three types of fertilisation (no fertilisation, 120 kg N+90 kg P2O5+106 kg K2O/ha, 240 kg N+ 180 kg P2O5+ 212 kg K2O/ha), three soil cultivation methods (without ploughing, with spring ploughing, with autumn ploughing), four types of plant density (60, 70, 80, 90 thousands plants per ha) and two types of irrigation (irrigated and non-irrigated).
