Soil Moisture Response to Short-Term Inorganic Fertilization on Tef (Eragrostis tef (Zucc.) Trotter) Crop Varieties in Northern Ethiopia

Figure 2

Soil moisture content in the 2012 cropping season affected by (a) fertilizer rates in a given soil sampling date and (b) growth stages (soil sampling dates) for the same fertilizer rate. Note: F (N + P) denotes fertilizer N plus P (kg·ha⁻¹) as 0 N + 0 P (F1), 21 N + 10 P (F2), 41 N + 20 P (F3), and 64 N + 25 P (F4); DAS, days after sowing, refers to the soil sampling date to determine SMC.
