T1 = N0 urea, T2 = N50%SA + N10%FA, T3 = N50%SA + N15%FA, T4 = N50%SA + N20%FA, T5 = N60%SA + N10%FA, T6 = N60%FA + N15%FA, T7= N60%SA + N20%FA, T8 = N70%SA + N10%FA, T9 = N100%SA, T10 = N100%SA + N10%FA. Means, followed by the same letters in a column are not statistically different at p < 0.05 according to the least significance difference (LSD) test.
