ABSTRACT
The performance and management of agriculture are affected by the climate uncertainty. The right choice of hybrid is among the potential adaptation options in agriculture to climate change. The aim of the present study was to define the productivity of five maize hybrids under non-irrigation and to establish the influence of the factor hybrid in accordance with the specific climatic conditions of the year on the grain yield, as well as on some qualitative and quantitative traits. The field trial was carried out on the territory of the village of Trapishte, region Razgrad with five corn hybrids- DKC4949 (FAO 390); DKC5031 (FAO 430); DKC4590 (FAO 370); P8523 (FAO 260) and P9537 (FAO 390). The following characteristics were reported: grain yield (GY); mass of grain per cob (MGC); cob weight (CW); number of grains per row (NGR); number of rows per cob (NRC); cob length (CL); test weight (TW); 1000 grains weight (TGW) and crude protein (CP). Hybrid DKC5031 is distinguished with the highest values of the crude protein. The largest cob weight and mass of grains per cob by hybrid P8523 were the prerequisite for the formation of the highest grain yields. Grain yield and the crude protein content were negatively related. In contrast to the other indices, the number of rows per cob and the cob length were not affected by the conditions of the year and it could be concluded that these components were influenced only by the hybrid.
