The Application of a Plant Biostimulant Based on Seaweed and Yeast Extract Improved Tomato Fruit Development and Quality
2020
Plant biostimulants are under investigation as innovative products to improve plant production and fruit quality, without resulting in environmental and food contaminations. Here, the effects of the application of Expando, a biostimulant based on seaweed and yeast extracts, on plant productivity, fruit ripening times, and fruit quality of Solanum lycopersicum var. Micro-Tom were evaluated. After biostimulant treatment, a two-week reduction of ripening times and a concomitant enhancement of the production percentage during the earliest ripening times, in terms of both fruit yield (+110%) and size (+85%), were observed. Concerning fruit quality, proximate analysis showed that tomatoes treated…
Evaluation of Small Vase and Y-trellis Orchard Systems for Peach and Nectarine Production in Mediterranean Regions
2015
Two peach planting systems, Small Vase (SV) and Y-trellis (Y), were evaluated and compared in the Mediterranean settings of Southern Italy. The two orchards were located next to each other on relatively uniform soil and terrain, and the observations included two peach (âRich Mayâ and âSummer Richâ) and two nectarine (âBig Bangâ and âNectarossâ) cultivars. In the SV system, trees were spaced at 4.5 A 2.5 m (888 trees/ha), whereas in the Y system, trees were spaced at 5.5 A 2 m (909 trees/ha) and no canopy gap was left between rows. Yield per tree; fruit size grade; unit price of sold peaches for each size grade; materials, labor and associated costs for cultural management;…
Yield and profitability of modified spanish bush and Y-trellis training systems for peach
2015
Peach trees trained to modified Spanish bush (MSB) and Y-trellis (Y) were evaluated and compared in the Mediterranean settings of Southern Italy. The observations included two peach (Rich May and Summer Rich) and two nectarine (Big Bang and Nectaross) cultivars. In the MSB system, trees were spaced at 4.5 x 2.5 m (888 trees/ha), whereas in the Y system, trees were spaced at 5.5 x 2 m (909 trees/ha). Costs at planting, yield per tree, fruit size grade, unit price of sold peaches for each size grade, amount and cost of materials and labor for cultural management, and grower's profit were quantified throughout all six years from planting and at full crop (year 4-6). Fixed costs of the MSB syst…

LOW VIGOR PEACH × ALMOND ROOTSTOCKS FOR INTENSIVE PEACH PLANTINGS IN MEDITERRANEAN ENVIRONMENTS
2014
A three-year trial was carried out to evaluate the vegetative and productive performance of five peach rootstocks of varied vigor. The study was conducted in south-western Sicily using 45 V-trained trees of 'Tropic Snow' peach planted in 2005 and grafted on GF677 and four low-vigor rootstocks selected at the Department of Agricultural, Food and Environmental Sciences, University of Pisa, namely IS5/8 (Polluce), IS5/19 (Castore), IS5/23, IS5/29. Trunk circumference, winter and summer pruning weight, number and mass of fruit were recorded from 2010 to 2012. All IS selections reduced trunk cross-sectional area (TCSA) and pruning weight compared to GF677 with IS5/23 inducing the highest reducti…
