Yield, Yield Components, and Nutritive Value of Perennial Forage Grass Grown under Supplementary Irrigation

Table 3

Species and year effect on the plant, dry matter, and crude protein yield of perennial grass evaluated under irrigation.

Parameters	Species	Year	S × Y	Mean	CV
Plant height (cm)				103.61	17.70
Dry matter yield (t/ha)				15.13	31.38
Crude protein yield (t/ha)				0.88	21.38
In-vitro dry matter digestible yield (t/ha)			ns	6.14	36.23

CV = coefficient variation;  = ;  = ; S × Y = species and year interaction; t/ha = tonnes per hectare.
