دراسة أداء الباذرة الميكانيكية كاسباردو في زراعة محصول الحنطة تحت الري التكميلي

الملخص EN

Wheat Field experiment was conducted at Albo-Nasser location in Nineva governorate under sprinkler irrigation system to study the performance mechanical seeder (Gaspardo).

Three factors were selected for this study (Sowing rate (S.R.) : 100, 120 kg / ha., Sowing depth (S.D.) : 4, 6 cm and forward speed of seeder (F.S.) : 4.5, 5.5 km / hr).

The experiment was set out as RCBD design with three replications.

The results showed that there was 30 % yield loss in grain yield under shallow seed depth.

The spike lengths and numbers of grain / spike were significantly higher when plants sown at seeding rate 100 kg / ha as compared with the other seeding rate used in this research.

Moreover sowing depth at the level of 6 cm and with ground seeder speed at 5.5 km / hr led to a significant increase in the following traits ; No.

of plants \ m2, actual field germination % and slippage %.

The interaction between S.R.

(120 kg / ha), S.D.

(6 cm) and F.S.

(5.5) km / hr led to significant increase in grain yield kg \ ha.

And higher value in No.

of plants \ m2 and accepted slippage percentage.
