Effect of Seeding Rate on Some Growth and Yield Characters of Three Rice Varieties

Abstract

The field experiment was carried out in rice research station in Mishkhab/Najav province in seasons 2013 and 2014 to study the effect of seed rate (60, 100, 140 and 180 kg ha-1) in growth and production characters of three rice varieties (Baraka, Yasmen and Furat 1) by using dry cultivation method. Randomize Complete Block Design RCBD was used in split plot arrangement with three replicates. The results showed that Yasemen variety was superior than the other varieties in growth and yield characters, seed rate 140 Kg ha-1 was superior compared to other treatments and given the best production (5452, 5492) Kg ha-1 for both seasons respectively, also the interaction between Yasemen variety and seed rate 140 Kg ha-1 was the best in growth and production characters in both seasons.
