Assessment of the effect of organic manure and biofertilizers on physiological attributes of cherry tomato genotypes

An experiment was undertaken to assess the effect of three levels of vermicompost doses and the biofertilizer on the physiological attributes of five genotypes of cherry tomato during the Rabi season in 2018-19 under open field condition. The physiological traits were observed significantly affected by organic manure and biofertilizer. The genotype 2018/TOC R-1 with leaf area index (2.29) and leaf area diameter 248103.9 cm² × days) was found slightly better than variety G4. 2018/TOC VAR-1 registered highest light transmission ratio (73.40%). As rega rds to physiological parameters, recorded the maximum, application of vermicompost 5 t ha⁻¹ and Azotobacter 4 kg ha⁻¹ chlorophyll content index (47.85), LTR value (69.04%), LAI (2.13) and lowest Ei (0.40 calcm⁻²min⁻¹). 2018/TOC VAR-1 under recommended dose of fertilizer gave the lowest magnitude of LTR (78.77%) and highest energy interception (0.61 calcm⁻²min⁻¹). Maximum LAI (2.41) and LAD (260603.7 cm²×day) was recorded in 2018/TOC VAR-6 grown with vermicompost (5 t ha⁻¹) and Azotobacter (T15).
