Grain Yield Seed Hybrids Maize per Different Way of Detasseling

Abstract

The experiments were conducted in field conditions, comprising two maize hybrids and two methods of detasseling, in the period 2014-2016 in a randomised block design. The seed yield was 3.64 t/ha, as average for all the hybrids and the methods of detasseling. “Suanito“ yielded 2.88 t/ha while “MAS 26K“ yielded 4.41 t/ha. The highest yield was obtained in 2015 (3.81 t/ha), then in 2014 (3.47
t/ha), while the lowest yield was obtained in 2016 (3.12 t/ha). Manual detasseling resulted in the seed yeld of 3.94 t/ha, whereas a significantly lower yield was achieved with mechanised detasseling (3.34 t/ha). There was a highly significant interaction found between the year and the hybrid, the year and the method of detasseling and the hybrid and the method of detasseling, whereas there was a significant interaction between the year, the hybrid and the method of detasseling.
