Effect of treatment with saline solution (NaCl) on rape plants in presence of the hemp shives

Abstract

The aim of this research was assessing the influence of hemp shives, like amendaments, in saline soils planted with rape (Brassica rapa L.). The growth and development assessing of rape plants in saline soils was achieved through biometric measurements for elongation and gravimetric measurements for the amount of biomass synthesized. Also, it was followed determination of the concentration of assimilating pigment (chlorophyll a, b, total carotenoid pigments) and protein content. It was found that adding hemp shives in soils with low salinity stimulated elongation and germination processes for rape. In soil with high salinity adding hemp shives determine an increase of biomass accumulation in all vegetative organs, comparative with the same salt concentration where we added the amendaments. Hemp shives can be recommended like natural amendaments for soils with high salt concentration.
