Research on the influence of distance between rows and fertilization on some morphoproductive elements in Bromus inermis Leyss. Species

Abstract

The research conducted during the period 2021-2022, at the Research and Development Station for Meadows, Vaslui (46°40'-36°10' north latitude and 27°44'-20°40' east longitude) followed the influence of fertilization and the distance between rows on the plants height (cm), shoots number (shoots·m-2), panicle length (cm), number of nodes per inflorescence, number of branches per inflorescence and seed production (kg·ha-1) for smooth brome (Bromus inermis Leyss.). The organized experience was bifactorial, 3 x 5 type, it was placed according to the method of subdivided plots, with the plot harvestable area of 20 m2 (2 m x 10 m), in three replications, and the studied factors were: A - the distance between rows with three graduations and B - fertilization with five graduations. Following the study, it was found that by applying mineral fertilizers and by sowing at bigger distances between rows higher plants were obtained, with a higher number of shoots·m2, also the panicle length, the number of nodes per inflorescence and number of branches per inflorescence and seed production were higher.
