In horizontal rows, means followed with different small letters are statistically different (P > 0.5) ( F value 1)
In horizontal rows, per each treatment, means followed with different small capital letters are statistically different (P > 0.5) (T value)
In vertical columns, means followed with different capital Italic letters are statistically different (P > 0.5) ( F value 2)
