  1. Data are mean ± standard errors. Different letters indicate significant differences according to the Duncan’s multiple range test (P < 0.05). Increase in yield = [(yield of treatment area — yield of control area)/yield of control area] × 100%; large tubers > 150 g, medium tubers ≥ 75 g, small tubers < 75 g
