Salata, A., Agricultural Univ. of Lublin (Poland)
The research on the yielding of rhubarb 'Wczesny Hosera' was carried out in the years 1995-2003 in the Experimental Station of Agricultural Academy in Lublin. The aim of studies undertaken in this work was evaluation of earliness and yield dynamics of rhubarb during successive 9 years of running the plantation. Effect of weather conditions in the winter-spring period on the yield earliness of rhubarb was proven. Depending on years, the first harvest of leaves was recorded on 10 April (in the year 2001), the last on 5 May (in the year 1997). In the period of 9 years of running the rhubarb plantation significant differences in the number of petioles picked from one plant were observed between years. Significantly lower petioles yield was harvested in the year 1995 (average 11.0 per plant), the highest yield was obtained in the year 2003 (average 87.5 per plant). The highest marketable yield of rhubarb 'Wczesny Hosera' petioles was obtained in the 6th to 8th year of running the plantation - in the years 2000-2002 (average 6.4-8.4 kg plantE-1).
