Present study was designed to explore a suitable technique for early root development in tomato cuttings, minimizing the cost incurred on the purchase of hybrid seeds for each and every time. Production of new crop through hybrids seedlings/cuttings and to get one or two extra crops while perennials crop introduced through cuttings which can survive for 2-3 years if there is no insect, pest & disease attack. Bio-regulators affect fundamental processes of plant growth and development. Experiment was conducted at NTHRI Shinkiari Mansehra, to investigate the growth and survival rate of tomato hybrid "Sahil" to response of varying concentration of Indole 3-Butyric Acid. IBA was applied @ (0.2 ppm, 0.4 ppm, and 0.6 ppm) on seedlings of tomato (Solanum Lycopersicon L.) to observe the effect on survival rate and root formation. It observed that the stem thickness, number of leaves, number of roots, root length and fresh weight of root were maximum at T3 (0.6 ppm). It was also found that the increasing concentration of Indole 3-Butyric Acid up to 0.6 ppm enhanced the all agronomic traits /growth of tomato hybrids seedlings under high shade. Moreover study was initiated as offseason vegetables during winter seasons both shade in walk-in tunnel and IBA had affected significantly. Source
