ABSTRACT
Different polyphenolics and biostimulants are used across the globe for enhancing productive and qualitative tarits of horticultural plants. A field trial was carried out in 2018-19 aiming at the evaluation of impacts of new commercial products “Quantis” and “Acevit-C” on growth, yield and antioxidative behaviour of bottle gourd cv. Aakash F1. Three level of Quantis (6 ml, 8 ml, 10 ml) and Acevit-C (100 ppm, 150 ppm and 200 ppm) were applied as foliar treatment following RCBD design. Results showed that impact of foliar application of both Quantis and Acevit-C on bottle gourd growth and reproductivity were significant. Moreover, application of 100 ppm Acevit-C and 10 ml/L-1 Quantis exhibited 6.5 and 11.5 fold increment in yield respectively as compared to control. The use of these plant products at variant concentrations showed an increase of antioxidant activity by upgrading superoxide dismutase activity (64.42 U mg-1 protein), peroxidase activity (1.90 µmol min-1 g-1 protein), catalase activity (37.81 nmol-1 g-1 protein) and protein (6.28 mg g-1 fresh weight) contents. These commercial plant products based on amino acids enriched macro and micronutrients as well as acetyl-salicylic acid combined with ascorbic acid can be used carefully for expecting efficient productivity with high quality produce.
