THE EFFECT OF CLIMATE FACTORS ON MAIZE YIELD OF LATE SOWING DATE

Abstract

Two-year research was carried out in 2014 and 2015 on the territory of the municipality of Leskovac, on alluvium land type. In the experiment, 6 maize hybrids of different vegetation lengths 400-600 were sown (ZP 434, NS 4023, ZP 555, NS 5051, ZP 666, NS 6030). The hybrid NS 6030 (10.248 t ha-1) had the highest average yield in 2014, while the hybrid FAO group 400 NS 4023 (9.467 t ha-1) had the lowest. The highest average yield in the year 2015, unfavorable for corn production, was achieved by the hybrid FAO group 400 ZP 434 (6.938 t ha- 1 Sowing time is one of the factors that have a significant impact on the level of corn yield (Glamočlija and Ugrenović, 2016; Biberdzić et al., 2018; Stojiljković, 2022). The optimal sowing period which could be defined as the sowing time, ensures the sprouting of corn at the most favorable moment, to make use of the conditions of the growing season and form the highest possible yield (Videnović et al., 2011). To achieve high and stable yields, numerous ), and the smallest yield by hybrid FAO group 600 NS 6030 (4.980 t ha-1). In 2015, being that the average temperatures were warmer than in 2014, and it had fewer amounts and worse distribution of precipitation, late sowing had a very bad effect on all hybrids, especially on FAO 600 hybrids.
