Effect of Protein Gel Treatments on Biometric and Biochemical Attributes of Tomato Seedlings in Greenhouse Condition

Protein hydrolysates are widely used in agricultural crops for improving plant nutrient uptake, growth, yield, and fruit quality. Tomato (Lycopersicon esculentum Mill.) is one of the most important vegetables consumed around world both its good taste rich content vitamins, minerals, lycopene, β-carotene. The objective present study was to assess effect new stimulant products based on protein obtained from animal tissue by-products tomato seedlings. Given increased intake amino acids, it expected that this treatment will exert beneficial effects development certain vigorous seedlings, representing premise obtaining superior plants improvement production quality fruit. Two variants gels gelatin keratin were by processing bovine hide wool periodical root applications seedlings cultivated a greenhouse. During experiment, biometric characteristics measured weekly. photosynthetic pigments, dry weight, sugars, polyphenols analyzed, antioxidant activity assessed leaves. research performed showed applied biostimulant treatments pigments 10%, sugars 75%, 16% compared control untreated variant. Between tested, best results applying mixture keratin.
