Abstract:
An investigation was carried out at the Technical Centre of Potato situated in the low valley of Medjerda River at Saida to determine whether intercropping increased production for small-scale farming in a semi-arid region (Tunisia). Crop productivity of potato and sulla intercropping systems was evaluated in terms of Total Dry Matter production (TDM). The effect of radiation interception and Radiation Use Efficiency (RUE) by these systems was measured to determine their productivity. Field trials were carried out during two crop growing seasons (2006-2007) and (2008-2009). Intercropping had no significant effect on the total dry matter production of potato and sulla. However, it increased the dry biomass of the intercropping system. This increase occurred during the two campaigns (2006-2007) and (2008-2009), respectively from 12.5 to 14.8% compared to the potato in sole cropping. Intercropping potato with sulla reduced the radiation interception by both crops. This reduction was in the two experiments, respectively (from 12.6 to 16.2%) and (from 3.5 to 17.4%) for both crops. Radiation Use Efficiency of potato in sole intercropping was improved from 11.2 to 11.4%. For sulla in sole intercropping, RUE has been improved only during the first experiment by 19.4%. From these results, it has been concluded that potato-sulla intercropping can be recommended to small-scale farmers in this semi-arid region.
