The point of this investigation was to assess the effect of protected systems and organic treatments on leaf reenness, physiology and development parameters of three green verdant vegetables (Indian spinach, Fenugreek and Amaranthus). Split-split plot designed was utilized to review the results of protected system (S), organic treatment (OT), crop types (C) and their interaction on the expansion and yield of vegetables for three growth stages. Data analysis of SPAD (Soil Plant Analysis Development) meter, chlorophyll quantification, IRGA (Infrared Gas Analyzer) and growth measurements were performed in triplicates (n=3) using agricolae package in R. Two-way variance assessment with mean separation by Tukey"s Least Significant Difference (LSD) at a = 0.05 was used to compare variations between structures (S1-2), organic treatments (OT1-5) and relationships between them. Results showed values for SPAD, chl. content and photosynthesis rate in polyhouse (S1) were significantly higher (p<0.05) than in shadenet (S2) in all 3 crops. For all three crops, the net assimilation rate and dry weight in the polyhouse were considerably greater (p<0.05) at all 3 growth phases. Higher SPAD values and values variation not only stated the vegetables ’ better output, but also helped to predict the correct time for their harvest. The findings showed that the polyhouse is appropriate compared to the shadenet for increasing short-lived leafy vegetables. Pre-soil sampling, detailed assessment of soil nutrient and biochemical content of organic leafy vegetables, however, would be helpful in making any recommendations on the selection of protected system type and organic applications.
