الملخص EN

A field experiment was conducted with the aim of studying and using an agricultural robot with combined Equipment, used for the process of seeding, fertilization and primary irrigation simultaneously.

In one of the experimental fields of the College of Agricultural Engineering Sciences/University of Baghdad in Jadriya, during the growing season 2020-2021, and testing it, to study its effect on some mechanical properties and some soil properties.

Two factors were used in the experiment: the first factor included, the speeds of the agricultural robot with three levels of the speed of the Mechanical unit which are: 3, 5 and 10 km.

h-1 and the second factor included sowing depth coefficients in three levels: 3, 6 and 9 cm.

Some technical performance indicators of agricultural robot have been studied and included: The number of individual seeds descending from the seed tube per square meter.

The number of seeds descending from the seed tube per square meter.

The number of double seeds descending from the seed tube.

The coverage efficiency of seeds per square meter.

The experiment was carried out by using the Nested Design under a complete ran-domized sector design with three replications and using the least significant difference with a probability ( LSD = 0.05 ) to compare between the averages of the treatments.

The results were showed the following: The highest distribution value of the number of descending seeds per square meter was at the practical speed of 3 km/h and at the depth of 3 cm، it was 30.03 corn / square meter.

The binary interaction between the working speed of 10 km/h, and at a depth of 9 cm gave the best value for the number of single seeds per meter of length which reached 9 seeds/meter of length.

While the bilateral interaction between the practical speed of 10 km/h and at a depth of 3 cm had the lowest percentage of double seeds amounted to 0.84% .

The effect of the bilateral interaction between the process speeds of 5 and 10 and seeding depths at 6 and 9 cm giving the best coverage efficiency ratio were 100% respectively.

The success of using the locally manufactured agricultural robot in the process of seeding fertilizing and first irrigation with high efficiency.
