Reserch on the influence of tehnological factors on seed production at the Bromus inermis Leyss in the third year of vegetation

Abstract

Seed production is undoubtedly of particular importance for the overseeding or reseeding of permanent grasslands and the establishment of temporary meadows, by providing the necessary seed material. The research conducted during the period 2022-2023, at the Research and Development Station for Meadows, Vaslui (46°40' - 36°10' north latitude and 27°44' - 20°40' east longitude) pursued the influence of fertilization and the distance between rows on seed production (kg/ha) for smooth brome (Bromus inermis Leyss.). The organized experience was trifactorial, 2×3×5 type, it was placed according to the method of subdivided plots, with the plot harvestable area of 20 m2 (2 m × 10 m), in three replications, and the studied factors were: A - variety (a1 - Mihaela, a2 - Iulia Safir), B - the distance between rows with three graduations (b1 - 25 cm, b2 - 37.5 cm and b3 - 50 cm) and C - fertilization with five graduations (c1 - unfertilized, c2 - N50P50, c3 - N50P50K50, c4 - N75P75K75 and c5 - N100P100K100). Following the study, it was found that by applying mineral fertilized with N75P75K75 and by sowing at 25 cm distances between rows seed production was higher.
