Abstract:
The present investigation carried out to check the Bio-efficacy study of Physio-activator (opteine) on eggplant cv. Pathakatta. The test product applied as foliar spray with seven different treatments i.e. 400ml, 500ml, 600ml, 7500ml, 1250ml/ha, control and Biozyme. The statistical analysis was done using Randomized Block Design (RBD) with three replications and seven treatments. It was noticed in the experiment that application of opteine enhanced the crop growth and promoted reproductive growth in later stages of crop compared to control plants. Amongst the different concentration of opteine it was observed that when the plant is sprayed with concentration of 600 ml/ha increased yield attributing characters such as number of fruits, fruit diameter and fruit weight ultimately fruit yield increased. The other parameters like plant height, number of branches, days to fruit set and days to first harvest shows positive effect with the application opteine @ 750 ml/ha. The fruit quality parameters like Anthocynin content was also influenced significantly with application of different concentration of opteine. It may be concluded from the present investigation that the application of Physio activator (opteine) as a foliar spray was found highly economical for brinjal production.
