| Abstract | ||
| Plant spacing and cultivar are the most effective parameters affecting growth and yield of the plants in greenhouse conditions. A field investigation was conducted with three levels of cultivar (Great Lakes, Dnor and Niner) and spacing (40 × 20 cm, 40 ×30 cm and 40×40 cm) to find out the effect of cultivar and plant spacing on yield and profitability for the two consecutive cultivation on year. Cultivar and Plant spacing, showed significant effect on yield and yield components of lettuce. The highest fresh yield of lettuce was obtained from the closest spacing (40× 20 cm) that was statistically similar to that recorded of medium spacing (40 × 30 cm) during two consecutive.Significantly higher fresh yield of lettuce was obtained from Great Lakes cultivar. The highest yield 25.48 ton/ha in one planting and 27.78 ton/ha in second planting was observed in the spacing of 40 ×20 cm with Great Lakes cultivar, which was statistically at par with the spacing of 40 ×30 cm with Dnor and Niner cultivar. The treatment combination of 40× 30 cm spacing gave the highest benefit cost ratio But the benefit cost ratio from the treatment combination of 40 ×20 cm spacing and Great Lakes cultivar was less due to the involvement of higher seedling cost. | ||
