Abstract
Background and Objective: Plant growth promoters are important factors for higher yield of vegetables to meet the population demand and earn a considerable amount of foreign exchange through exporting it. The present research work was undertaken to study the effect of oligo-chitosan (O. chitosan) on growth, yield attributes and economic yield in tomato and egg-plant under Bangladesh conditions. Materials and Methods: Randomized complete block design (RCBD) with three replications was done during the period from 2015-2016 to investigate the effect of oligo-chitosan application on morphological characters, growth and yield in tomato and eggplant). Three levels of oligo-chitosan concentration viz. 0 (control), 60 and 100 ppm. O-chitosan was sprayed five times after sowing. Biochemical compositions of tomato and eggplant from chitosan treated plants were observed. The collected data were analyzed statistically using MSTAT-C v 3.2 and the mean difference were adjudged by Duncans Multiple Range test. Results: The present results revealed that plant height and number of flowers plant -1 increased with increasing concentration of chitosan till 100 ppm. Treatments with 60 and 100 ppm O-chitosan were effective in increasing total yield plotG 1 of tomato (41.67 and 38.30 kg, respectively) than control (22.79 kg). In tomato, the acidity and protein content has been significantly (p<0.05) decreased from plant treated with 60 ppm chitosan whereas 100 ppm chitosan treatment significantly (p<0.05) increased protein content in eggplant. There were no significant differences between 60 ppm chitosan treatment and control on ash and pH value of tomato and eggplants. Chitosan treatment (60 and 100 ppm) significantly (p<0.05) decreased total soluble solids (TSS) content in tomato but showed reverse phenomenon in eggplant. Higher dose of chitosan reduced vitamin C content in both tomato and eggplant although 60 ppm increases vitamin C compared to control in tomato. The powerful antioxidant (phenolic content) component has been found to be increased (p<0.05) significantly with chitosan treatment in eggplant but decreased only with lower dose in tomato. Conclusion: It was concluded that foliar application of oligo-chitosan at early growth stage enhances growth and functional components of tomato and eggplant.
