The study was conducted to evaluate the effect of planting geometry and training on growth and seed yield of tomato (Solanum lycopersicum L.) using cultivar Solan Lalima during Kharif 2013 at Experimental Farm of Department of Seed Science and Technology, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.). The treatments comprised of four training levels i.e. Y1 (single stem), Y2 (double stem), Y3 (unpruned with horizontal string) and Y4 (unpruned bush stakes (control)) and eight plant densities viz. S1 (60×15 cm), S2 (60+30×15 cm), S3 (60×30 cm), S4 (60+30×30 cm), S5 (90×15 cm), S6 (90+30×15 cm), S7 (90×30 cm) and S8 (90+30×30 cm). Analysis of variance showed that the treatment combination Y1S7 (single stem and plant spaced at 90×30 cm) resulted in maximum ripe fruit length and width (5.86 cm and 5.06 cm, respectively), maximum number of seeds/fruit (110.67), minimum days to ripe fruit harvest (71.00) and maximum harvest duration (59.84 days) but gave the low seed yield. The combination Y2S5 (double stem and 90×15 cm) resulted highest seed yield i.e. 519.71 kg per hectare. Therefore, planting density S5 (90x15 cm) in combination with training system Y2 (double stem) may be recommended for commercial seed production of tomato.
