Etude comparative de l'irrigation au goutte-à-goutte et à la raie sur une culture de pomme de terre de saison

Abstract

Comparative Study of the Drip and Furrow Irrigation on Seasonable Potato Crop. Under semi-arid climate conditions, use of furrow irrigation for potato is relatively low when compared to drip irrigation. An experimental trial was carried out at the Agricultural Research Station at Chott-Mariem located in the Center East of Tunisia. A drip irrigation system with three amounts (D, 0.75D and 0.5D) was compared to blocked furrows (D) on potato. The drip irrigation system (D = 210 mm) produced best results for dry and fresh matter production in leaves and stems, and in tubers, percentage cover of soil and plant height. Lower amounts of water applied (0.75D and 0.5D) with drip irrigation gives similar results to those obtained with furrow irrigation (D).
