Effects of NPK Fertilization on Yield and Fertilizer Use Efficiency of ‘Altari’ Radish (Raphanus sativus L.)
Year: 2022
Type: article
Abstract: This study was carried out to investigate the effects of NPK fertilization on growth and production of 'Altari' radish.N, P 2 O 5 and K 2 O fertilizer application rates were 5 levels (0, 50, 100, 150, 200%) by practical fertilization (N-P 2 O 5 -K 2 O = 113-83-73 kg ha -1 ), respectively.In the N treatment, yield and nitrogen use efficiency were the highest at 113 kg ha -1 fertilization, and decreased with further increases in N rate.In the P 2 O 5 treatment, root growth, yield and phosphorus use efficiency were the highest at 83 kg ha -1 fertilization and decreased with further increases in P 2 O 5 rate, but phosphorus recovery was the highest at 41.5 kg ha -1 fertilization.In the K 2 O treatment, yield and potassium use efficiency were the highest at 73 kg ha -1 fertilization and decreased with further increases in K 2 O rate.By the regression equation between the content of NPK fertilizer application and yield, the highest yields were obtained with the application of 140-86-87 kg ha -1 as N-P 2 O 5 -K 2 O, respectively.
