The paper presents the characteristics of soil and climate conditions at the Experimental Station in Zawady, belonging to University Of Natural Sciences And Humanities in Siedlce, cultivated area, grain yields and harvest the four species of cereals were given (winter rye, triticale, spring triticale and spring wheat). In soil and climatic conditions in the area of RSD on the largest area triticale was planted, which harvested on the highest level, which let to get the largest yields. But the lowest grain yield was taken from winter rye and spring wheat. Cereal grain yield in research years was differed by conditions of rain and temperature. Difference in grain yield in relation to the average of the decade ranged from -36.5% to 58.3%, depending on years and species.

Results of the 3-year field experiment carried out in 2005-2007 at the Ex-perimental Station in Zawady near Siedlce on good rye complex soil are presented in the paper. The oat phonological stages progress depending on weather condi-tions in vegetation period was estimated. The weather conditions in years of investigation were diversified. Exceptionally unfavorable conditions were in season 2006 - the great precipitation deficiency was noted. In following years the effects of three sowing rates (300, 500, 700 germinating seeds/1m2) on three oat cultivars (Polar - hulless cultivar, Bachmat and Rajtar - hulled cultivars) was evaluated. It was indicated that the decisive influence on oats growth and yield had the weather conditions in experimental years, also with experience factors: seed spacing and cultivars. The highest yield was noted in favorable 2007 year. The sowing rates increase caused the substantial growth of grain yield. Among examined cultivars the highest yield had Bachmat cultivar. ...
Many agro-technical factors are of great importance concerning the amount of crop in corn production. One of these factors is nutrient supply. Plants are supplied with macro-, meso- and microelements. Nowadays cultivated plants cannot always obtain enough microelements from the soil, therefore the importance of foliar fertilization increased. Applied at the right time, foliar fertilization might increase the resistance of corn against biotic and abiotic factors as well. In the experiment the authors examined the effect of three foliar fertilizer products and their combinations on the important elements of the crop development of corn, and their application from economic point of view. The experiment was set in three repeats in random blocks on meadow soil in 2015. The nitrogen supply of the soil is good, the phosphorus and potassium supply is very good, however the zinc content of the soil is low. The corn yield without foliar fertilisation was 6.39 t/ha. The highest yields were achieved after the following treatments: Amalgerol + Fitohorm Turbo Zn (7.50 t/ha), Fitohorm Turbo Zn (7.35 t/ha), and Algafix + Fitohorm Turbo Zn (6.94 t/ha). Treatments with products containing Zn resulted in the best amounts of yields indicating that the low Zn levels of the ...
