Effect of fertilizers treatments on growth and yield of groundnut L14 variety in autumn-winter season in Thai Nguyen province Vietnam
Research of the effect of fertilizers on groundnut L14 variety. Study was replicated 3 times with 6 fertilizers treatments: T1 = 8 tons muck (M) – control treatment; T2 = T1 + 90P2O5, T3 = T2 + 500 lime, T4 = T3 + 30N, T5 = T4 + 60K2O, T6 = T5 + (Bo, Mo, Mn, Zn, Cu). Results: fertilizer treatments not affected on high stem, branches, leaves, area leaf index of groundnut. The T2, T3, T4, T5, T6 treatments were dry of pod yields were 23, 70-29,10 quitas/ha, increased 3.60-9.00 quitas/ha in pod yield compared to T1. Difference about dry of pod yields between T2, T3, T4, T5, T6 treatments and T1 are declared highly significant.
