Studies on the optimum sowing date and sowing density of the Lonas annua (L.) vines et druce sown directly into the ground and cultivated for dried bouquets

Abstract

In the years 1998–2000, studies were undertaken to determine the optimal sowing date and sowing density for the field cultivation of (Lonas annua (L.) Vines et Druce). Seeds were sown in three different periods, on the following dates:1^st period – 4^th May, 29^th and 28^th April; 2^nd period – 14^th , 10^th and 8^th May; 3^rd period – 24^th , 20^th and 19^th May. Five sowing rates were applied on each of the sowing dates, i.e.: 40, 60, 80, 100 and 120g·100 m ^-2  .The favourable influence of the early sowing dates on the plants quality was observed. Moreover, it was proved that plants grown on plots with the lowest sowing rates were characterised by the highest number of embranchments of the I order.
