Abstract
The sustainability of seed production in Cuba has been affected, among other causes, for the low quality of seed. This work aimed to study various agrotechnical aspects in growing pumpkin to improve seed quality. The experience was developed at the Liliana Dimitrova Horticultural Research Institute during the months of January to November of 2002-2004 crop years. The behavior of six varieties was evaluated; four planting times were studied and a fruit post-harvest handling was realized taking into account the maturity degree of the fruits (green, half-ripe and mature) and time of seed extraction (10, 20 and 30 days post-harvest). Yield variables and seed quality were evaluated. All tested varieties achieved good yield with good germination. It was found that the best time to produce seed is November, since the values were significantly higher and found a significant effect on the performed post-harvest handling. The best results in yield and seed quality are obtained from half-ripe fruit whose seed is removed within 20 days of harvest.
