A study was conducted at Horticultural Research Institute, NARC, Islamabad, Pakistan during 2009. The axillary/lateral shoots (3-4 inches long) were taken from tomato (cv. Kurihara). The cuttings were dipped for 30 seconds in 0.25, 0.50, and 1.00 percent solutions of Indole Butyric Acid (IBA), Chinese Hormones (ABT), Naphthalene Acetic Acid (NAA), 4-Chlorophenyl Acetic Acid (4-CPAD) and control, planted in multi-pot trays filled with a mixture of well decomposed farm yard manure (FYM) and soil (1:1). All the treatments were triplicated using complete randomized design. The data were recorded on survival percentage, seedling height (cm), stem diameter (cm), shoot and root fresh weight (g), shoot and root dry weight (g), root and shoot ratio, root length (cm) and number of roots per cutting. Maximum seedling height (32.22 cm), root length (17.40 cm), number of roots (27.20), root/shoot fresh weight (0.78 and 9.65 g) and dry weight (0.23 and 1.87 g), was noted in control. It proved that tomato axillary/lateral shoots can be grown successfully in a media prepared with soil and well decomposed FYM in 1:1 ratio. This technology can be successfully utilized to grow the second crop of the same variety/hybrid saving the seed cost.
