This paper reviews sunflower hybrid seed processing at Institute of Field and Vegetable Crops Novi Sad with all practical, technical and technological solutions. Additionally, efforts of Institutes employees are presented here in creating new technical solutions, particularly machines, aimed at their adaptations in existing sunflower seed processing, in order to get better quality and quantity of the processed seed. The paper also reviews original solution of the seed processing improvement with the new machines, regarding their position in the system and their connection in the semiautomatic operation system, with the possibility of independent operation. Seed processing results in high quality sunflower hybrid seed produced and ready for the severe market competition. [ABSTRACT FROM AUTHOR]

It is very important to keep the quality of the sunflower seed, which must be kept in the warehouses. The standard treatment of sunflower seed was treatment with the fungicide. New trend for the seed quality improvement is treatment with the insecticides as well. Seed germination energy of hybrid NS-H-111 that was kept in cooling chamber was higher then the energy of seed that was kept in the warehouse for the 4.31%. This difference was statistically significant. Seed treated with fludioxonil + metalaxil + imidakloprid that was kept in the cooling chamber, has the higher germination energy for 13.5 % the then the seed kept in the warehouse. The difference was highly significant. Seed kept in the cooling chamber had, in average, higher germination for the 3.94 % in relation of the seed kept in the warehouse. In average, for Sremac hybrid, the highest values of seed germination were when the seed was kept in the warehouse. This difference wasn't statistically significant in relation to the other two examinations. The germination energy was higher at fludioxonil + metalaxil + tiametoxam treatment (93.75 %). Investigation of Sremac seed germination in different storage conditions, in average, hasn't any statistically significant effects. The highest germination was at treatment fludioxonil + metalaxil + tiametoxam and its amount was 94.92 %. This is statistically significant difference in relation to fludioxonil + metalaxil + imidakloprid treatment (for 5.09 %). Seed without treatment, which is kept in the cooling chamber, had the highest germination energy. [ABSTRACT FROM AUTHOR]
