Abstract

Afield experiment was carried out in the 2021 main (mehere) cropping season to examine physiological trait response of durum wheat- varieties under different N fertilizer rates. The treatments consisted of five levels of N fertilizer (0, 46, 69, 92 and 115kg ha-1) rates with recommended P2O5 (100 kg ha-1) plus absolute control (without NP fertilizer application) and three durum wheat varieties (Utuba, Et cross-21, and Mangudo) arranged in factorial combination using randomized complete block design with three replication. The results revealed that, leaf chlorophyll content, normalized vegetative index at 30 days after sowing and stomatal conductance, were highly significantly (P<0.01) affected by the main effect of nitrogen fertilizer level. The highest chlorophyll content at 30 days after sowing (40.0%), at days after sowing (42.7%), normalized differences vegetative index at 30 days after sowing (64%), stomatal conductance (0.57 gswmol m-2), were recorded at the rate of (115kg ha-1) nitrogen. crop growth rate (CGR), relative growth rate (RGR) and normalized vegetative index (NDVI) at 60 and 90 days after sowing were significantly (P<0.01) affected by the interaction effect of N fertilizer and durum wheat varieties. Regarding varieties, the highest Soil Plant Analysis Development (SPAD) value at 90 DAS was recorded at Et cross -21 variety. From the current result, positive responses were observed between durum wheat physiological traits and N rates. However, it is valuable to carry out further research over locations and over seasons.
