INFLUENCE OF WIDTH OF SPACES BETWEEN ROWS ON FORMATION OF YIELD OF SWITCHGRASS VARIETIES

Abstract

The quantitative indexes of vegetative aboveground mass of switchgrass varieties: Cave-in-Rock, Carthage and Foresburg with different width of spaces between rows. Increase of plant nutrition areas causes shortening plants but the number of stems has a tendency to increase when the plants were grown with wider spaces between rows during the third and fourth vegetation years.

Established yield value of dry phytomass of switchgrass varieties of the third and the fourth vegetation years with different areas of plant nutrition have been determined.
