PERFORMANCE STUDY OF GASPARDO MECHANICAL SEEDER IN SOWING WHEAT UNDER SUPPLEMENTRY IRRIGATION

Abstract

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 ,120kg/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 6cm and with ground seeder speed at 5.5 km/hr led to a significant increase in the following traits ;No. of plantsm2 ,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 kgha. And higher value in No. of plantsm2 and accepted slippage percentage.
