Effects of Different Row Spacings and Different Fertilization Doses on the Seed Yield and Some Agronomic Characteristics of the Tall Fescue

Özet

This research was carried out in the ecological conditions of the Pamukova district of the Sakarya province between November 2013-July 2016, in order to determine the seed yield and some yield properties of the tall fescue (Festuca arundinacea Schreb.) plant sown at different row spacings and with different fertilization doses. The experiment was conducted in the randomized block design with 4 different (0, 10, 20 and 30 g m-2 ) fertilizer doses and at 2 different row spacings (20 and 40 cm). In this research; vegetative shoot number (count m-2 ), seed yield (g m-2 ), straw yield (g m-2 ), biomass yield (g m-2 ), harvest index (%) and winter endurance (1-9 point) were determined. At the end of study, the highest values were obtained from in the 20 cm row spacings and 30 g m-2 fertilizer dose compare to control.
