Abstract

This work aimed at to evaluate the efficiency of a no till seeder regarding to the uniformity of fertilizer and corn seeds (Zea mays L.) distribution among the sowing lines and in function of the treatments composed by the combination of three sowing speeds (3,3; 7,1 and 9,8 km h-1) and three levels of products in the reservoirs (1/1, 1/2 and 1/6 of its capacity). It was verified that the increase of the speed didn't interfere in the seeds and fertilizers distribution. The products level in the reservoir influenced in the amount of distributed fertilizer. Reservoirs totally supplied provided increase of 5,8% in the fertilizer dosage in relation to the level of 50% of its capacity. The product level in the deposits didn't influence the reason of seeds distribution. Both for seeds and fertilizer, significant variations occurred in the dosages among the sowing lines.
