Interaction effect of amendments and metals on dry matter production in different brassica species (Brassica compestris and Brassica nigra)

Abstract

Brassica juncea (Indian mustard) is important in oil production, has medicinal properties and is used as a condiment. It is a tolerant plant to heavy metals, grows fast and produces large amount of above-ground biomass. Due to these characteristics, this species has been the target of several studies to evaluate its phytoremediation potential. Individual application of FYM and CaCO3 in mustard effective and significantly increased the dry matter production at flowering in the crops over SSp and CaCO3 + FYM amendments. The increased dry matter yield due to the application of FYM FYmay be attributed to the fact that The increased dry matter yield due to the application of FYM may be attributed to the fact that FYM not only acts as store house of nutrients in soil but also capable of improving physicochemical condition of soil. CaCO3 being a liming material also supplies Ca a secondary nutrient elements to crops and improves the soil structure.
