- Observation Giza 181 exceeded Giza 175 in grain yield.
- Observation Giza 181 exceeded Giza 175 in straw yield.
- Observation Giza 181 exceeded Giza 175 in nitrogen uptake.
- Observation Giza 181 exceeded Giza 175 in nitrogen efficiency and recovery.
- Intervention effect Splitting nitrogen between dry soil and 20 days AT significantly increased grain and straw yields, uptake, efficiency and recovery.
- Association Higher nitrogen levels increased grain yield, straw yield and total nitrogen uptake.
- Association Rice variety and nitrogen timing interacted significantly for grain yield.
- Observation Giza 181 had highest grain yield with half nitrogen in dry soil and half at 20 days AT.
- Observation Giza 181 had highest total N uptake with 60 kg N/fed. split between 20 days AT and PI.
