Phosphorus use efficiency of buckwheat (Fagopyrum esculentum Moench)

Abstract

The research was carried out with aim to investigate to effect different phosphorus doses (0, 2, 4, 6 and 8 kg P2O5 da-1) on yield and phosphorus used of buckwheat in Isparta in 2014 year. The experiment was set up according to a randomized complete block design with three replicates using the Aktaş buckwheat cultivar. In the research, grain yield, agronomic efficient, physiological efficient, agro-physiological efficient, recycling efficient and utilizing efficient with Mineral nutrient content of buckwheat were investigated in different phosphorus practices. The highest grain yield (132.3 kg da-1) was obtained from 8 kg da-1 phosphorus dose, however, among the 4, 6 and 8 kg da-1 phosphorus doses weren’t statistically significant. The highest agronomic efficient (7.17%), physiological efficient (0.51%), agro-physiological efficient (0.24%) and utilizing efficient (21.48%) were obtained from 4 kg da-1 phosphorus dose and the highest recycling efficient (48.3%) from 6 kg da-1 phosphorus doses. Mineral nutrient content of buckwheat was increased depending on increasing phosphorus doses, and among the 4, 6 and 8 kg da-1 phosphorus doses weren’t statistically significant expect for phosphorus and manganese element of buckwheat. The lowest values of mineral content in buckwheat were determined in non-fertilizer treatments.
