Abstract
In order to be able to provide useful indications for the reintroduction of peanuts in the Italian territory, the aim of this work is to compare the production yields of the peanut variety grown in two areas, San Severo (FG) and Frignano (CE), evaluating the total losses experienced during the extraction and harvesting phase. The seed was positioned at a depth of 3-5 cm, with a planting layer of 0.08 m on the row and 0.75 m between the rows. Scrape Hull method was used, which consists of starting five representative plants in different part of area, get 100 developed pods is used. The peanut harvest is divided into two phases. For the first phase, the excavation phase was used the 2– row Digger-inverter COLOMBO C-200. The second phase of the harvest, in both areas, was carried out with the Colombo Double Master II Harvester, a machine specialized in the harvesting of peanuts and beans. The variables analyzed to evaluate the peanut mechanization process were: Estimated yield, Excavation losses, Harvest losses and net yield. The estimated yield was made before the excavation phase, 3 plots of 11.25 m2 (15.0 m x 0.75 m) were used in each area. The excavation losses were divided into visible losses (VDL), invisible losses (IDL) and total excavation losses given by the sum of the visible and invisible losses. For this purpose, to manually collect the visible leaks, metal frames (n.3/areal) of about 7.5 m2 (10.0 m x 0.75 m) were positioned through the swaths. The harvest losses were sampled after the harvest of the Colombo Double Master II Harvester machine. The net yield was calculated considering the estimated yield net of total excavation losses added to harvest losses. The estimated excavation losses in both territories were practically equal, 0.79 q/ha in Frignano, equal to 2.89% of the estimated production, and 0.76 q/ha in San Severo, equal to 2.41% of the estimated production. The losses in the subsequent phase of separation of the pod were 2.08 q/ha in Frignano, approximately 7.6% of the estimated production and 1.79 q ha in San Severo, equal to 5.7% of the estimated production. Overall, total crop losses were 10.49% (2.89 q/ha) in Caserta and 8.11% (2.55 q/h) in the Apulian fields. The results achieved in this first experimental cultivation test with the use of mechanization yards not known in the area, show that with greater accuracy of the cultivation techniques and an improvement of the harvesting phase it is possible to have a margin for improving the production level, obtaining yields greater than about 10%, which in relation to the commercial value of the product can represent a significant increase in the profitability of cultivation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
