Bio-Efficacy Study of Physio-Activator (Opteine) on Tomato (Solanum lycopersicum L.)

Abstract

The present investigation conducted in the year 2016 - 2017 to check Bio-efficacy study of physio-activator (opteine) on tomato cv. PAN 1286. 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. From the results it was concluded that application of opteine increased total and marketable yield. The application of opteine showed positive effect with respect to vegetative, reproductive yield and quality parameters compared to water and biozyme spray. Amongst different concentrations, opteine spray of 600 ml/ha produced highest fruit weight, fruit yield, fruit diameter, number of fruits per plant and minimum days to fruit set. The dose of 750 ml/ha of opteine found better for plant height, number of branches. The fruit quality parameters like lycopene, anthocynin, TSS, beta carotene and total sugar content were also influenced with application of opteine. It was concluded that sea weed extract application enhanced crop growth and ultimately increased fruit yield.
