Enhancing the Growth and Productivity of Chia (Salvia hispanica L.) Using Compost and Biostimulants

A two-year field study conducted during the ۲۰۲۲/۲۰۲۳ and ۲۰۲۳/۲۰۲۴ seasons evaluated the effects of organic manure and biostimulant foliar applications on chia (Salvia hispanica L.). The experimental design involved applying compost at rates of ۰, ۱۰, ۱۵, and ۲۰ m³/fed, and foliar sprays of two biostimulant substances: a blend of amino acids (at ۱۰۰ and ۲۰۰ ppm) and seaweed extract (at ۲ and ۴ ml/l). The results indicated that compost application significantly improved growth parameters, yield, fixed oil production, and chemical constituents, with the highest compost rate (۲۰ m³/fed) generally exhibiting the greatest positive effect. Foliar treatments with both amino acids and seaweed extract further enhanced these traits, particularly when seaweed extract was applied at ۴ ml/l. Moreover, significant interactive effects were observed between compost and biostimulant treatments; notably, the combination of ۲۰ m³/fed compost with seaweed extract at ۴ ml/l resulted in the most pronounced improvements in all measured parameters.
