evaluate the effects of tillage systems on soil bulk
density, yield and quality of potato crop (Solanum tuberosum
L.), three different tillage techniques were studied:
reduced tillage using discs harrow (RT), medium tillage
depth using discs plow (MT) and conventional deep tillage
using moldboard plowing (CT) with three working depths of
10, 20 and 30 cm respectively. Tillage was followed by a
first resumption after 10 days and a second one after 20
days. Soil structure was characterized by its bulk density
and potato quality by tubers size and yield. Samples were
collected from tilled plots at different dates spaced of 20
days. The obtained data were tabulated and analysed using
IBM SPSS 17.0 version and Tukey test. Compared to MT and RT,
CT decreased bulk density to 1.16 g cm-3 against 1.23 and
1.4 g cm-3 60 days after tillage respectively for the two
previous tillage systems and increased tubers size and
consequently the potato yield to an average of 11 Mg ha-1
compared to 9 and 7 Mg ha-1 respectively for MT and RT. The
statistical analyses of the data showed significant effects
of the treatments and the measurement date on soil bulk
Keywords: Tillage systems, soil structure, bulk density, tubers size, potato yield.
