Production of pumpkin cv" Kafr Saad"(C. moschata), Damietta landrace, was assessed for plants rose from chilled seeds and girdled plants comparing with untreated ones when grown 50, 75 and 100 cm apart. Sowing was done on May of summer 2010 and 2011. The greatest number of leaves per plant and the highest leaf total sugar content (35 and 40 d after planting) was detected when growing at 75 cm within-row space. Growing plants 75 cm apart gave the highest fruit yield. Fruit yield of plants from chilled seeds substantially surpassed the yield of girdled plants and untreated. The increase in the yield from plants rose from chilled seeds averaged 36.00–40.44% over that of the untreated plants. Girdling either did not change the fruit yield or slightly reduced it as compared to control treatment. Fruit harvested from plants grown 75 cm apart was larger in weight than those produced from plants grown 50 cm apart but smaller than others grown at 100 cm. However, growing at 75 in-row space produced fruits containing elevated carotene, TSS and dry matter comparing with the other spaces. These internal fruit traits were the highest in girdling followed by seed chilling treatments. This study recommends growing pumpkin 75 cm apart employing seed chilling as a simple treatment that adding no production costs while can significantly enhance fruit yield and quality.
