“…Berihun et al [6] found that different land management practices (no crop cultivation on steep slopes >30%, Khat plantation, Forage production, Reforestation on communal and hilly croplands resulted in a reduction in the soil loss by 32-95%. Comparing our results with other studies, it can be verified that the NT cultivation in lands with slope can significantly reduce the soil loss [7,15,19,20]. Furthermore, the parallel to the contour cultivation is more affectively to the decrease of the sediment loss [29].…”

Soil erosion is one of the biggest problems in the agricultural sector that can affect ecosystems and human societies. A field of 50 slope was selected to study the runoff, soil and nutrients’ loss as well as crop productivity in different treatments (conventional tillage (CT) vs. no-tillage (NT), plant vs. no plant cover, contour cultivation (CC) vs. perpendicular to the contour cultivation, (PC) under natural rainfall. The experiment was conducted in central Greece in two cultivation periods. In autumn, the field was cultivated with intercropping Triticosecale and Pisum sativum and in spring with Sunflower. The total rainfall was 141.4 mm in the 1st year and 311 mm in the 2nd. We found that runoff in the treatment of no tillage with contour cultivation was 85% lower in both years compared to the no tillage-no plant control. Therefore, the contour cultivation-no tillage treatment had a positively effect in decreasing phosphorus and potassium concentrations lost from soil: indeed, there was a decrease by 55% and 62% in P and K, respectively, in the NT compared to the CC treatments. We conclude that the NT-CC treatment with plant cover was the most effective in reducing water runoff, soil nutrients’ loss and increasing yield.

“…In recent years, conservation tillage has been mentioned as an effective way to reduce soil erosion and therefore to minimize the soil and nutrients' losses [12,13]. Conservation agriculture has three main principles, no -tillage cultivation, crop rotation and use of permanent cover crops [14,15].…”

“…Faced with such a situation, conservation agricultural practices, particularly a no tillage (NT) system is a promising alternative for adapting production systems to the difficult conditions of the Mediterranean regions and thus ensuring sustainable production [19][20]. Indeed, research has shown that this system makes better use of water, conserves the soil against the different types of erosion by improving its organic matter content and structural stability, and increases agricultural production [21][22][23][24]. Because of the NT generated benefits in terms of yield, sustainability, incomes, timeliness of cropping practices, ease of farming and eco-system services the area is of NT systems is approaching 25 thousand hectares in Morocco but 205 million hectares worldwide [25].…”

In Morocco, the intensive use of agricultural land coupled with irregular precipitation is a serious threat to the country's food security. Conservation agriculture especially no-tillage (NT) system has shown an important result in the semi-arid regions of Morocco, but its dissemination to other, more humid, agro-ecological zones (precipitation > 350 mm) is still low. For this purpose, a field experiment under NT system has been installed since 2004 in the Zaer Plateau (Central Morocco) to study the adaptation of this system to the irregular rainfall compared to a conventional tillage (CT). Yields (grain and biomass) of crops (wheat and lentil) under NT and CT were analyzed and compared over the years of study. The ANOVA test showed that yields over the seven years were significantly different and that both crop yields under NT system were greater than or equal to those under CT system even though lentil is more vulnerable to extreme climate events under CT and NT systems. Unlike NT, yields under CT were significantly correlated with the rainfall amount received during the crop cycle. This indicates the dependence of CT precipitation, whereas NT is more adaptable to the irregularities of the climate in the study area.

“…In many countries all over the world the raise of the fertilizers' price in combination with the increasing of fossil fuels' cost had led the producers to turn their interest in conservation agriculture which including lower impact cultivation practices such as no tillage cultivation, permanent crop residues on the surface and crop rotation [6,7]. The conservation tillage is able to significantly improve soil properties (physical, biological, and chemical) and other biotic factors, reduce the soil erosion, improve the water infiltration and also helps in the reduction of the production's costs [8][9][10].…”

The objective of this work was to investigate the effect of different soil tillage practices in sunflower cultivation in a rotation system with intercropping Triticosecale x Pisum sativum. For this purpose a two year experimental field of 5% slope was established in central Greece. There were four treatments with three replications each. The treatments were: (a) no tillage - planting parallel to the contour (NTC-PAC), (b) conventional tillage - planting parallel to the contour (CTC-PAC), (c) no tillage - planting perpendicular to the contour (NTC-PEC), (d) conventional tillage - planting perpendicular to the contour (CTC-PEC). During the experiment plant height, leaf area index, specific leaf area, plants’ total nitrogen and plants’ proteins were measured. According to the results plant height ranged from 64.9 (CTC-PAC) to 85.2 cm (NTC-PEC) the 1st year and between 66.5 – 86.5 cm in CTC-PAC and NTC-PEC treatments in the 2nd year. Furthermore, LAI and SLA, plant’s total nitrogen and protein content and N-uptake were affected positively by the no tillage practice. To conclude, sunflower is a promising crop in a rotation system with intercropping Triticosecale x Pisum sativum, cultivating under rainfed sloping conditions.
