    Researches carried out in the years 1962 and 1963 proved that the defoliation of seed yellow lupine is very important in wet years. Spraying the seed plantations of lupine with chemical burning preparations, applied during pod browning on the main stalk, shortens considerably the ripening period of plants without detrimental effect on yields and germination of seeds. Good results were obtained applying 5 kg of Krezamon, the Polish preparation, in 500 liters of water per hectare or 500 liters/ha of 2% caustic soda.

    Wpływ nawożenia azotowego na plon mieszanek ozimych.

    In the years 1960-1962, researches were carried out at the Agricultural Experimental Stations: Lipki and Ostoja for nitrogenous fertilization of winter catch-crops (winter vetch + rye). The applied fertilization consisted of 20, 40, and 20 + 20 kg N/ha. The fertilizers were applied in two terms and so the mixtures were cut. The obtained results proved that nitrogenous fertilization of winter catch-crops increased the green mass, protein, and carotene yields and sped up their soilage. The dressing of 20 + 20 kg N/ha applied in two terms heightened the protein content in the winter mixtures.
