background: biostimulants are amino acids and organic components, which can play main role in the plant growth and dry matter accumulation. objective: determine the influence of foliar application of active amino acids on quality and quantity yield of melissa officinalis l. methods: this study was conducted in a research farm at the institute of medicinal plants on the base of randomized comple...

To obtain a better understanding of the mycorrhizas as an elicitor, and precursor feeding effects on the protein content and TIAs biosynthesis in Catharanthus roseus L., foliar application of four concentrations of tryptophan (0, 150, 250 and 350 mg/l) on some growth parameters and chemical compositions of mycorrhizal plants were investigated. The results revealed that the total protein content...

The most important characteristic of stevia is its high sweetness with zero calories which is due to the presence of Steviol glycosides (SVglys). This research aims to address the effect of salicylic acid (SA) and microelements viz. iron (Fe) and zinc (Zn) under different soil water potentials (-0.5, -3.5, -6.5 and -10 atm) on the production of SVglys and total sugar content in the leaves o...

Effective methods of supplying Zn to fruit trees are needed to combat widespread deficiency of this element all over the world. Soil applications are not very effective because the roots of fruit crops occupy deep soil layers and zinc does not easily move in the soil. Although foliar sprays are more effective, foliar-absorbed Zn is not easily translocated in plants, which necessitates repeated ...

Beneficial plant–microbe interaction for enhancing crop yield and quality is a sustainable way to achieve eco-friendly, desirable agricultural productions. The main objective of this experiment was evaluate the individual combined effects an arbuscular mycorrhizal fungus (AMF) strain (Funneliformis mosseae) seaweed extract (SWE) derived from Ascophyllum nodosum, on growth physiological response...

Little attention has been paid to the diagnosis of deficiencies of micronutrients such as zinc (Zn) and boron (B) and secondary nutrient such as sulphur (S) in rainfed systems. We evaluated Zn, B and S status of 1617 farmers’ fields in 14 districts of the semi-arid tropical India. Results showed that most of the soil samples were low to medium in organic carbon contents. Results also revealed t...
