초록
The aim of this present study was to investigate the impact of different seeding rate andnitrogen fertilizing levels on the seed yield and feed value of oats(Avena sativa L.) grown inGyeongbuk area for two years. The experiment was arranged in split plot design with 3 mainplots(100, 130 and 160 kg of seed/ha) and 4 subplots(0, 50, 70 and 90 kg N/ha), with3 replicates. Heading, flowering, and maturing dates of oats sown in spring 2017, delayed by twodays compared to that of spring 2016, and the plant height of spring 2017 were significantlyshorter than that of spring 2016(18.1 ~ 23.4 cm). In addition, the highest number of stems andnumber of panicles according to different seeding rate and nitrogen fertilizing levels wereachieved with the seeding rate of 160 kg/ha and 90 kg of N/ha in 2016 and 2017, respectively. In case of seed yield as affected by different seeding rate, the highest seed yield was achievedwith a seeding rate of 130 kg/ha(p<0.05), and based on nitrogen fertilizing levels, the highestyield was obtained in 50 kg of N/ha compared to others. The crude fiber(CF), neutral detergentfiber(NDF) and total digestible nutrients(TDN) of oats cultivated and harvested in spring2016 and 2017 according to different sowing rate were the highest in the seeding rate of130 kg/ha. The crude protein(CP) content and total digestible nutrients(TDN) of 2016-2017 asinfluenced by nitrogen fertilizer levels were the highest in the nitrogen fertilizer level of 90 and50 kg N/ha, respectively. In conclusion, the proper seeding rate and the optimal nitrogenfertilizing level in Gyeongju, Gyeongbuk province were considered to be the most appropriatein 130 kg/ha and 50 kg of N/ha, respectively.
