Abstract
<p>Efficiency of application of various forms of nitrogen fertilizers on crops of spring wheat Novosibirsk 31 is shown. During the growing season the main phenological observations were made. In the phase of the beginning of milk ripeness of wheat defined a number of indicators related to plant productivity: the number of productive stems per unit area, plant height. In the ripening phase, the elements of the crop structure were studied: the number of productive stems, the number of spikelets in the ear, the number of grains in the ear, the mass of 1000 grains. Economic efficiency of cultivation of culture is calculated.</p>
