The effect of different sowing depths on fresh ear yield and some ear characteristics of sweet corn
Abstract
The research was conducted with aim to investigate effect on fresh ear yield and some ear characteristics of sweet corn of sowing at different depths during 2015 and 2016 years in Isparta. The experiments were set up according to randomized complete block design with three replicates using BATEM TATLI sweet corn cultivar. Furrows were opened at depths of 10 and 20 cm after the soil preparation, and seeds were sown in the 4-5 cm depth in to these furrows. According to means of years, while furrow sowing increased ear diameter, ear weigh, number of kernels per ear and fresh ear yield compared to control, it was not effect on ear length. In the research, between 10 cm and 20 cm furrow sowing wasn’t significant statistically. Fresh ear yield in control, 10 cm and 20 cm furrow sowing were measured as 1110.9 kg ha-1 , 1228.4 kg ha-1 and 1289.4 kg ha-1 , respectively. According to results of research, 5 cm deep sowing in 10 cm furrows should be advised in sweet corn cultivation.
