EFFECTIVENESS OF SYMBIOSIS BETWEEN FODDER GALEGA (GALEGA ORIENTALIS LAM.) AND RHIZOBIUM GALEGAE ON FALLOW LAND

Jadwiga Andrzejewska, Stanisław Ignaczak

 

ABSTRACT



A three-year field experiment investigated the effectiveness of symbiosis between extremely extensively used fodder galega (Galega orientalis Lam.) plants and Rhizobium galegae. A bacterial culture was obtained from root nodule bacteria and applied onto seeds prior to sowing. In summer each year, over the maximal biomass development as well as in autumn the weight of the underground and over-the-ground plant parts was measured, including the content and accumulation of basic elements. The effectiveness of symbiosis between inoculated and non-inoculated plants was visible with a more rapid development, twice higher biomass increase over the sowing year, eleven-fold higher over the second research year and fifteen-fold – over the third year. Inoculated plants contained on average by 1% of nitrogen more than non-inoculated, and over the third research year, over the greatest biomass development, accumulated from a few to a few dozen-fold more phosphorus, potassium, magnesium, cal

Key words: Galega orientalis, Rhizobium galegae, inoculation, symbiosis effectiveness, biomass, nutrients, fallow land.
