Table 1 Rainfall amount (mm), irrigation (mm), soil moisture change and evapotranspiration for the 80, 50 and 30 % FC soil moisture content and rain fed treatments

From: Irrigation levels affects biomass yields and morphometric characteristics of range grasses in arid rangelands of Kenya

Rainfed
Rainfall (P) (mm)	54.2	224.2	204	242.5	297.9
Irrigation (I) (mm)	0	0	0	0	0
Soil moisture change (ΔS)	33	79	85	67	113
Evapotranspiration (ET)	21.2	145.2	119	175.5	184.9

Rainfed treatment did not have supplemental irrigation and hence the zero values in the irrigation row
