  Fennel appers to be cupable of enlarging our vegetable sortiments in Hungary. Ecological conditions favour production. For cultivation, 12,5 plants/m2 are recommended. Fennel requires 250-300 mm water over a 110 day growing period. No considerable pests have been found yet. 1-3 kg/m2 tubers can be harvested. Marketable tubers weigh 200-300 g. Smaller tubers can be dried, pickled or deep frozen.

  The hinge of the lupine crop cultivation technology is the sowing time and the determination of the breeding area. According to the literature the early sowing (as soon as possible to go to the soil) and larger growing area is recommended for seed production. Based on the results of our 2 years experiment, the effect of sowing time and different spacing is important on yield of white lupine, and the effect of the sowing time is more significant. A decrease in the yield was observed after later sowings. The yield and the rate of its decreasing was varied in one year and among different years depending on wheather condition and sowing time.

  The role of sowing time is significant for protein content of seeds. The average protein content decreased due to the later sowings in 2014, while 2015 the protein content of seeds in early sowing time and of plants sowed 4 weeks later was similar. We measured less protein content in the 2. sowing time sowed 2 weeks later than the first one. In the studied years the average protein content of seeds from different row spaces were not different.

  Based on the results of a previous experiment, we concluded that by choosing a suitable cultivar, it is possible to produce artichoke in a one-year cultivation system in Hungarian weather circumstances. The objective of the present experiment was to investigate the performance of two Californian artichoke cultivars (Green Globe, Imperial Star) under the local conditions. Experiments were conducted in 2002 and 2003, by using four
  different sowing and two different planting dates (03.01. and 03.20. – planting 05.07.; 04.24. and 05.06. – planting 06.12.). For both cultivars, 100% of the plants initiated buds. In most of the cases, Imperial Star produced higher total and marketable yields than Green Globe did, while it formed bigger and more uniform buds. Our opinion is that the main reason for this result was that Imperial Star tolerated the dry and warm Hungarian summer much better. Irrespective of the variety by earlier sowing dates higher total yield was achieved. Based on our results, we found that under Hungarian circumstances, both cultivars could produce acceptable total yields. However, the weather circumstances of the given year influenced bud quality, and thus marketable yield, to a great extent.

  Producing sugar beet, as it is a demanding field crop, has contributed to the raising standard of plant production. It has an outstanding place among the plants that are cultivated in the intensive plant production system. Rentability of sugar manufacture is determined by the stability of yield and the quality (saccharose content) of sugar beet. In this way, the fundamental interest both of the producers and the processing industry is high yield and quality, year by year. The yield and the quality of the sugar beet are mainly determined by the plant production system, so we studied the effect of fertilization, irrigation and plant protection.

  In Hungary today is about 5 million hectares of agricultural land contaminated with ragweed. The ragweed problem a year is about 60 billion HUF to be paid, of which 30 billion are used to reduce the agricultural damage. Experiments with ragweed pollen has mainly been carried out in connection with terms of allergy. The other biochemical experiments and studies with this plant, have so far been the scientific horizons of public life, boosted the edge. We wanted to demonstrate that the ragweed, which is a weed, containsbiological active (for example: antifungal) compounds. For our experiments in the previous cycle of flowering, plants were collected manually, with its roots and with each plant part. The extraction of the substance from dry plant – meal was carried out using appropriate solvents. The biological activity of ragweed-extracts were tested against fungi isolated from soils and meadow with different mode of cultivation. Our results suggest that ragweed contains biologically active substances, which inhibit the growth of fungi, depending on the concentration of active ingredients of the plant.
