Valutazione di ecotipi siciliani di melone d'inverno coltivati in regime seccagno

The increasing cultivation of hybrid melon cultivars has caused the loss of several Sicilian landraces characterized by a high level of diversity, tolerance to environmental stress, disease resistance, and high quality fruits. Although the majority of hybrid melon fields in the Sicilian countryside are nowadays irrigated, many farmers are still growing melon landraces without irrigation. In this trial, eight Sicilian landraces of winter melon (Cucumis melo L. var. inodorus Naud.) with yellow skin and three with white skin were compared with the commercial cultivar Helios. Plants were grown at a density of 2080 plants ha-1. without irrigation. ‘Locale di Ustica’ and ‘Giallo di Recattivo’ gave the highest yields. ‘Giallo di Jopppolo’ was the least productive. Average fruit weight was highest in ‘Locale di Ustica’ and lowest in ‘Giallo di Sutera’. ‘Giallo di Castronovo’, ‘Giallo di Sutera’, Giallo di Valledolomo’, ‘Bianco di Raffadali’, and the commercial cultivar Helios had higher Total Soluble Solids (TSS) than the others

Epoche d'impianto e sistemi di allevamento per il fagiolo "Badda"

The bean landrace"Badda" has been cultivated since long ago in the Madonie mountains in the northern side of Sicily.It is characterized by a bush indeterminate habit and comprises two ecoty termed 'Badda bianca ' and 'Badda nera' according to the seed colour. This paper describes the results of a study on the effects of four sowing dates (June 15 and 30, July 15 and 30) and two vertical training sustems 8a frame of Arundo donax dry canes or a trellis consisting of several strands of wire) on productivity of the phaseolus landrace 'Badda bianca'. Marketable yields obtained from 15 june sowing were significantly higher than those from June 30 and July 15 sowing dates which in turn were significantly higher than those fron July 30. Sowing dates had no effects on number of seeds per pod and 1000-seed weight. the two training systems had no influence on yields. However, trellising with wire strands resulted in a more practical training approach

Valutazione di diversi sesti di impianto del fagiolo "Badda"

Two bean ecotypes, termed ‘Badda bianca’ and ‘Badda nera’ according to the seed colour, have been grown since a long time near two villages, Polizzi Generosa and Castellana Sicula in the Madonie mountains (Sicily). An experimental trial was carried out to compare the effects of four different row distances (90, 120, 150 or 180 cm) and three plant densities (2, 4 or 6 plants per hole) on yield, number of seeds per pod, seed weight. Total yields on plots with row spacing of 90, 120, or 150 cm were significantly higher than that on plots with plants spaced 180 cm apart. Yield per plant lowered as plant density increased. Number of seeds per pod and seed weight were not affected by the treatments tested. Vertical training of the plants with a plastic net resulted in a more practical growing approach as compared to trellising with the traditional frame of Arundo donax dry canes
