Abstract
Excellent wheat yields can be obtained by increasing the yield perunit area by selecting new cultivars and by pointing out the most favourable agricultural practices.
the density of plant population is directly related to the seed rate at sowing. at the same time, competion between plants becomes areat and this requires an increase in the amount of nitrogen to meet with the incrasing demand of the plants perunit area. also qrowth requiators has been considreed as an essential practice in wheat cultivation program. the present investigation aimed to study yield and yield attributes of both sakha 8 and sakha 69 wheat as influenced by: Nitrogen fertilization and urea.
Seeding rate and cycocel (ccc).
