  The lupine is very sensitive to the different ecological conditions. The examinations of lupine was started in 2003 and our aim is determine yield components which directly affecting crop yields (flower, pod and seed number per plants) in different sowing times (3 times, two weeks apart) and growing area area (240, 480, 720 cm²) combinations. According to our results the sowing times, the growing area and the meteorological conditions are influence on yield significantly. Our data suggest that the early sowing and large growing area combination is favourable to rate of fertilized plants and to development of yield. Later sowing reduces the seed yield depending on the cropyear. In our experiment, the decrease of yield was in the unfavourable year (2003) 20–96%, and in the most favourable meteorological conditions (2004) 10–79%, and in rich rainfall year (2005) 15–88%.

  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.

  We examined 35 early, 32 mid-season and 12 mid-late winter wheat varieties on calciferous chernozem soil after sunflower green crop in 2003. We set-up the experiment on small-size parcels, with 4 repetitions. In addition to the favourable agrotechnical conditions, with this year’s extreme ecological conditions the varieties resulted in weaker yields (2500-3200 kg/ha). Our findings have proven that there is a significant difference both between the maturity groups and between the yield potential of varieties with different genotypes, inside each group. Early varieties showed lower yield potentials according to the other two groups. The differences between the various variety’s yields was the smallest in the mid late group (893 kg/ha). Under given ecological and agrotechnical conditions, the following varieties showed the relatively best yields and best adaptability:
  • early maturing varieties (3200-3700 kg/ha): Mv palotás, KG Magor, Mv Mambo, Mv Emese, GK Margit, GK Tündér, GK Csongrád, GK Attila, Mv Amanda, Ukrainka;
  • mid season varieties (3300-3800 kg/ha): Győző, GK Marcal, Róna, GK Rába, Buzogány, MF Kazal, GK Mura, Hunor, GK Cipó, Mv Magvas, Mv Vilma, GK Zugoly, Jubilejnaja 50;
  • mid-late varieties (3200-3600 kg/ha): Maximus, Complet, KG Kunhalom, GK Holló.
