  The Stopgril liquido (S), a foliar fertilizer containing nitrogen, calcium and magnesium was used to improve the spring and the summer growth of grafted walnut plants in the second year of cultivation in the nursery. To accomplish early termination of vegetative growth and good lignification, the composed mineral fertilizer Hascon M 10 AD (H) containing phosphorous, potassium and microelements B, Mn and Mo was applied on the same plants. Four treatments (S, H, SH, C) were applied three times in a growing season. Their effects on the height and the basal diameter of the plants in the nursery depended on the starting height of the plants and the time of application. During the first growth period in the orchard, the number of developed buds on the plant, the circumference of the plants and their height were influenced by the treatment in the previous year in the nursery. According to the results obtained through the investigation, three applications of Stopgril + Hascon in the nursery per year can be recommended in order to obtain high enough and well lignified two-year-old grafted walnut plants.

  In our days about 2 million tons of garlic are grown in the world. Garlic was used as medicine already in ancient Egypt. It contains approx 33 sulfur compounds, several enzymes, 17 amino acids and minerals. We determined the content of diallyl sulfone, boron, calcium, copper, iron, potassium, magnesium, natrium, phosphorus and zinc in fi ve garlic varieties (3 French, 2 Hungarian). We searched if there were signiffi cant differences between the varieties.

  According to our experiments the tested group of non-destructive methods offers a useful tool not only to follow the texture changes of vegetables during storage but to characterize the firmness and vision parameters during the growing period as well. Advantages of these methods are: they are mobile, easy to set up, easy to use and quick. The suitable maturity state — and so the optimum harvest date also - can be determined by these methods. In addition, these methods can be built into sorting lines making possible to sort and classify great amounts of produces. These methods help the producer to offer homogenous products of controlled quality. They can be used for measuring different effects on vegetable's quality parameters (fertilization by different microelements, different irrigation effects on the product) as well.
