Effect of pre-sowing treatments on growth of Karonda (Carissa carandas) seedlings

Abstract

The present investigation was conducted at Fruit Research Station, Imalia, Department of Horticulture, College of Agriculture, J.N.K.V.V., Jabalpur (M.P.). The experiment was laid out in Factorial Randomized Block Design with three replications and sixteen treatment combinations. It was carried out to investigate the effect of seed soaking duration (24 hours and 48 hours), growing media (with and without pseudomonas) and concentration of cow urine (0, 25%, 50% and 100%) and their combination on growth of Karonda. The result revealed that treatment T6 with seed soaking duration of 24 hours in 25% cow urine followed by sowing in growing media incorporated with pseudomonas @ 6 ml kg-1 soil was found superior with respect to various growth parameters such as seedling length (32.80 cm), length of roots (20.64 cm), seedling vigor index I and II (2764.62 cm & 136.93g), survival percentage (87.66%) over the other treatment combinations.
