Foliar Application of Essential Micro nutrients (Mn+Zn+B). To Control Salinity and Allelochemical Stress With Respect to Sunflower (Helianthus annuus L.) Growth

      Аннотация: Nowadays, Salinity and Allelopathy are the key factors causing decrease in growth and productivity of almost all the crops. An alternative approach for coping with salinity and Allelochemical stress could, therefore, be to attempt to supplement essential sodium antagonistic minerals through foliar application. This idea behind the present work is to diminish effect of salinity and allelopathy in plant to a tolerable level. The aim of the present study was to assess as to whether foliar applications of micro nutrients were effective in inducing salt stress tolerance in sunflower plants. Keeping this in view, an experiment was carried out to study the interaction of boron (B), manganese (Mn) and zinc (Zn) on growth and physiology of Sunflower (Helianthus annuus. L)plant.
