ABSTRACT



In a three-factor experiment set up as a ‘split-plot’, at the RZD Pawłowice, in the vicinity of Wrocław, the following were investigated: the effect of: I – pea cultivar: Agra – semi-leafless and ‘Rola’, traditional – bipinnate leaves; II – nitrogen fertilization: 0, 30, 60 kg·ha-1; III – harvest date: green, yellow and full maturity, on the development of the seed sowing value. The cultivars researched did not differ in their germinative energy and germinability, while 1000 seed weight and leachate electroconductivity were higher in ‘Rola’ than in ‘Agra’. There was shown a positive effect of nitrogen fertilization at the dose of 30 kg·ha-1 on 1000 seed weight, while the other parameters of the sowing value did not depend on the sowing value of this factor. As ripening progressed, until full maturity, there was recorded a significant increase in 1000 seed weight, germinative energy and germinability and in vigor measured with the leachate electroconductivity. A positive correlation between 1000 seed weight and germinative energy and germinability of seeds and a negative correlation between the germinative energy, germinability, 1000 seed weight and the leachate electroconductivity after 12 and after 24 hours.

Key words: pea, sowing value, cultivars, nitrogen fertilization, harvest date.
