Nowadays plant derived protein hydrolysates using as foliar application in crop production is an intention especially in the organic agriculture. Uptake mechanisms are not well described however presumably it is got into primarily through stomas. The main advantage of hydrolisated protein as organic nitrogen fertilizer is that it can provide readymade building blocks for protein synthesis. At the same time some protein-building amino acids are fundamental metabolites in the process of vegetable tissue formation and chlorophyll biosynthesis. Hence the increased chlorophyll concentration can contribute more intensive photosynthesis. In our case the objective was to investigate the effect of different plant (soybean, lupine and pea) derived protein hydrolisates in 2 mg L-1 concentration as foliar application for some quantitative, qualitative and physiological parameters of red pepper and tomato in field experiment. As expected on the basis previous experiment no significant difference was shown in the average weight of tomato nor green pepper. However the soy protein hydrolysates increased the photosynthetic pigment content both in tomato and green pepper leaves. The photosynthetic efficiency were higher applied lupin and lupin+pea hydrolysates in the same vegetables however all the treatments were in the normal concentration range (0.75-0.85 mg L-1). As concern the qualitative parameters significant increasing were measured in the ascorbic acid content of pepper samples using all treatment and the total carotene also was significantly higher in case of soy hydrolysate.
