The low NPK (N:P:K at 140:70:140 kg ha−1), normal NPK (N:P:K at 280:140:280 kg ha−1) and low NPK + GA3 (gibberellic acid; 10 mg L−1) treatment groups. Each of the three treatment groups were further subdivided into (Control, K, P, PK, N, NK, NP, and NPK) treatments.
Plants were harvested on June 20 (1st harvest H1), August 10 (2nd harvest H2), and October 10 (3rd harvest H3), 2015, of ramie, respectively. Data followed by different lowercase letters (a, b, c) in the same column indicate statistically significant differences within a harvest; values followed by different uppercase letters (A, B, C) in the same row indicate significant difference between harvests at p < 0.05 based on LSD test.
