CASTAGNINO, A. M et al. Adaptation of a new vegetable (Curcurbita pepo var. vegetable spaghetti) to different growing conditions. Rev. Chapingo Ser.Hortic [online]. 2008, vol.14, n.3, pp.281-287. ISSN 2007-4034.

Spaghetti squash is an alternative crop with qualities that have aroused interest among Argentinean consumers. The objective of this experiment was to study the influence of sowing date and density in Cucurbita pepo var. vegetable spaghetti. The study was conducted in the experimental unit of the Facultad de Agronomia in Azul, Argentina, in a typical argiudol soil on a total area of 5,952 m². Each plot had an area of 88 m² and comprised four 11 m rows, 2 m apart. The two middle rows were evaluated. There were two sowing dates (November 10^th and 24^th) and four sowing densities (0.25, 0.5, 0.75, and 1 m between plants, that is, 20 000, 15 000, 10 000 and 5000 pl·ha^-1). Band fertilization as well as preventive chemical weed-control with Naptalan, on sowing line and Trifluralina between rows with a cultivator, took place at presowing. Data were analyzed under a model of divided plots, in which the main plot was biostimulants and the sub-plots density and sowing date. The interactions between main factors were also considered. No significant differences were detected for total crop weight among the effects of interaction between sowing density and date. With crop densities two and three, more medium (two and three caliber) fruits (1.05 and 1.44 kg) were obtained. These calibers are suitable for marketing.

Keywords : squash; density; sowing date; fruits.
