1. Quality of sunflower seeds in function of thickness classification and sowing under speed variation of the seeder-fertilizer
ABSTRACT The objective was to evaluate the quality of sunflower seeds classified according to their thickness and passed through the seeder-fertilizer dosing system under variation of the travel speed. A lot of M734 was classified by thickness passing the seeds through a set of oblong-hole sieves and two thicknesses were selected. A portion of the seeds with

2. PERFORMANCE OF CORN SOWING IN FERTILIZATION SYSTEM AND INTERCROPPING
ABSTRACT The performance of the tractor-seeder can be influenced by factors related to the seeder, as loads and crop. The aim of the present study was to evaluate the performance of tractor-seeder at sowing in the corn crop in function of the fertilizer systems (at presowing and at sowing) and those intercropping of crops (corn + bean-Stizolobium deeringianu

3. Tratamento de sementes, densidade e método de semeadura de Brachiaria brizantha no consórcio milho e braquiária / Treatment of seed, density and sowing methods of Brachiaria brizantha intercropping maize and pasture
The integrated crop livestock farming system is an important training and renovation of degraded pastures. However, lack technical information about physiological and sanitary quality of the forage seeds and sowing methods have been suggested as causes of failure in some fields. This work aimed to evaluate the effects of treatment of seeds of Brachiaria briz

4. DESEMPENHO DE DOIS PROTÓTIPOS DE SEMEADORAS-ADUBADORAS PARA PLANTIO DIRETO / PERFORMANCE OF TWO SEEDER-FERTILIZERS PROTOTYPES FROM DIRECT SEEDING
With the objective of evaluating the acting of two seeder-fertilizer prototypes for the direct seeding system, works were developed in field conditions and evaluation track according to international standard. The experiments were conduced in the years of 2007 and 2008, evaluating two prototypes, one of precision seeder-fertilizer and another of multiple see

5. Influência da profundidade de adubação e da velocidade de uma semeadora de plantio direto na cultura do feijão / Influence of fertilization depths different and of speed of a seeder under no-till system in common bean culture
Brazil is the largest producer and consumer of beans in the world, what explains the importance of research on this crop. In order to obtain success in implanting a given crop with minimum soil ploughing, the no-tillage system has been applied, with a seeder-fertilizer making the necessary cuts of the crop residues on the soil surface and placing the seeds a

6. Influence of either operational speed and the pressure applied on compress wheels in the initial establishment of the maize crop under no-till system / Influência da velocidade operacional e da carga aplicada pelas rodas compactadoras sobre o estabelecimento inicial da cultura do milho em sistema de plantio direto
Since Brazil is one of the main maize producers throughout the world, this crop becomes an important target for research. To obtain the successful implantation of the crop, a good soil-seed contact should be promoted, besides to be careful about the good distribution of the plantlets. The no-till planting minimizes the undesirable effects from the preparatio

7. WHOLE-BODY VIBRATION SEAT TRACTOR ANALISYS / ANÁLISE DO NÍVEL DE VIBRAÇÕES NOS ASSENTOS DE TRATORES AGRÍCOLAS
Nowadays, whole-body vibration is widely recognized as risk factor for worker all around the world. Most of published works on this subject was developed in main research centers. The aims of this study were (1) to determine the vertical whole-body vibration levels on the tractor seat, (2) to determine the combination influence between three tire inflation p
