Biological Components Efficiency on Safety and Productivity of Different Tomato Cultivars

Abstract

Biological agent plays an outstanding and also effective role in agricultural systems with the reducing chemical components applications. This three yr study investigated the bio-growth regulators (with anti stress activity and plant resistance against diseases) efficacy on productivity and safety of four tomato varieties with the goal of sustainable agriculture during 2013 – 2015. Biological active substances were epin extra, zirkon, tekamin max and immunotsitofit that were performed as following levels: Soaking in 0.2% solution for 6 hours, Soaking in a 0.2% solution for 6 hours and one time foliar treatment, Soaking in a 0.2% solution for 6 hours and two time foliar treatments, one time foliar treatment, two time foliar treatments and control as a water treatment respectively. Tomato (Lycopersicon esculentum) cultivars in this study were Sultan F1, Lodzheyn, Dar Zavolzhja and Beta. Results of this study revealed that epin extra caused the highest germination of Sultan f1 and Dar Zavoljia significantly; germination of Beta was improved when tekamin max (TM3) was used. Bio-agent tekamin max in all cases had favorable improvement on tomato morphology of all tomato cultivars. Three records of observation on blight spread on tomato cultivar Dar Zavoljia concluded that blight disease was significantly diminished when tekamin max (TM3) was performed. Overall, tekain max as a biological growth regulator was distinguished as the most efficient on growth and development of tomato, and also the lowest blight infection was observed when tekamin max was applied.
