Yield and mineral nutrition content of buckwheat (Fagopyrum esculentum Moench): The effect of harvest times

Karabuğday (Fagopyrum esculentum Moench)’ın temel yetiştirme amacı, insan beslenmesinde özellikle glütene hassas ve hipertansiyon hastalığı olan insanların beslenmesi için tane elde etmektir. Bu çalışma karabuğdayın verim, farklı hasat zamanlarında bitkide, bitki organlarında ve tanesinde mineral besin içeriğini araştırmak amacıyla 2012 ve 2013 yıllarında yürütülmüştür. Araştırmada Güneş karabuğday çeşidi kullanılmıştır. Karabuğdayın verim ve mineral besin içeriği bitki organlarına ve hasat zamanlarına göre değişmiştir. Karabuğdayın taze ve kuru ot verimi, farklı bitki organlarında ve hasat zamanlarında mineral besin içeriği istatistiksel olarak (p

Karabuğday (Fagopyrum esculentum Moench)’ın verim ve mineral besin çeriği: Hasat zamanının etkisi

Buckwheat (Fagopyrum esculentum Moench) is cultivated primarily to obtain grains for human consumption, especially gluten sensitive patients and hypertensive people. The present study was conducted to investigate the yield and mineral nutrient contents in plant organs, the harvest times and grain of buckwheat in 2012 and 2013. The Güneş species were used as the buckwheat cultivar. The results revealed that the yield and mineral nutrient content of buckwheat varied according to both plant organs and harvest times. The herbage-hay yields and mineral nutrient contents in plant organs and harvest times of buckwheat were statistically (p<0.01) significant in both years. A mean grain yield of 1460.8 kg ha-1 was obtained in 2012 and 1592.6 kg ha-1 in 2013. The mean seed mineral nutrient contents of both years were found to be very close to each other. At harvest times, the highest herbage (27393.3 and 27603.1 kg ha-1, respectively) and hay yield (7661.3 and 8536.7 kg ha-1, respectively) were determined at the 5th harvest time (the latest harvest time), the lowest herbage and hay yield was obtained from the first harvest time in both 2012 and 2013. The herbage and hay yields increased by delaying harvest times. The highest mineral nutrition contents, except for Zn, were determined in the second harvest time. The lowest mineral nutrition contents varied according to the harvest times in both years. In comparison with different plant parts, the highest herbage (4638.4 and 4975.7 kg ha-1, respectively) and hay yield (1616.2 and 1684.3 kg ha-1, respectively) were determined in the stem, while the lowest herbage and hay yields were obtained from flower organs in both 2012 and 2013. The highest mineral nutrition contents were obtained from the leaf and flower organs whereas the lowest mineral nutrition contents, except for K, were determined in the stem in both years.
