Introduction: Lentil (Lens culinaris Medik.) is a versatile and profitable pulse crop and is mainly cultivated in the Mediterranean Basin, Australia, West Asia and North America. In Greece is an important traditional crop mostly used for human consumption and is cultivated in ⁓ 5,200 ha with an average yield of 1.2 t ha-1. ‘LENSBREED’ is an operational research project under the National Action "RESEARCH- CREATE-INNOVATE" [2014-2020 (EPAnEK) - (project code: T1EDK-04633)] co-funded by Greece and the European Union (EU) (Total budget: 993,217.00 €). ‘LENSBREED’ will utilize and properly manage the available genetic material of local lentil populations in terms of its agronomic, physiological and quality properties with the ultimate goal of highlighting and improving the special characteristics of Greek primary products with varietal identity. Objective of the study: Determination of the most suitable locations/areas for high quality and profitable lentil yield according to their special pedo-climatic conditions.

Pedoclimatic conditions are critical in lentil production although, their interaction with the genotype has not yet been widely explored. Among the main goals Map of multi-location field experiments in Greece of the LENSBREED project is the determination of locations/areas suitable for high quality and lentil yield according to their special pedo-climatic conditions. Locations/areas suitable for lentil cultivation will be identified through the establishment of an extensive multi-location assessment network with field experiments. Ptolemaida Orestiada Methods: Seed yield (gr/2.5m2) of five genotypes under conventional farming within 8 out of 10 locations (preliminary results 2019) Petrana SOIL SAMPLING: (0-30 cm) at the beginning of the growing season from trials Komitini of 10 locations shown in the Map and analyzed for: Particle size distribution, Larissa pH (water 1:1), Electrical Conductivity (ΕC), % CaCO3, Organic Matter content Thessaloniki (OM), Available phosphorus (POlsen), Total soil N (%TSN), Exchangeable cations + + ++ ++ (K , Na , Ca , Mg ), Cation exchange capacity (CEC), Soil micronutrients A. Anargiroi (DTPA, Cu, Fe, Mn, Zn), and Boron (B), METEO: Monitoring of the microclimate in each area with a portable meteorological station (program Ypato Legumini.net). GENOTYPES: commercial cultivars ‘Samos’, ‘Thessalia’, ‘Elpida’, ‘Dimitra’ and a local population ‘03-24L’. FARMING SYSTEM - EXPERIMENTAL DESIGN: All treatments were applied under conventional and organic farming conditions in a RCB design. DURATION: 36 months (2019-2021). Preliminary results and Conclusions: -1 -1 -1 Most soils were clayey, slightly alkaline (pH=7.1-8.0), with low EC (<1000 μS cm ). OM content was mostly low (<1.5%) and soils were either deficient (<10.0 mg P kg soil) or moderately sufficient (10-20 mg kg soil) in POlsen. %TSN was either low (0.13%) or extremely low (0.06%) whereas, in most locations soils were sufficient in K+. In most locations CEC was high (> 25 cmolc kg-1 soil) and exchangeable cations were found in the following decreasing order Ca++> Mg++> K+ > Na+. Plant available soil Cu, Fe and Mn were found high or very high and Zn content was adequate. The content of soil available B was high (1.0-2.0 mg kg-1 soil) in most locations. -1 -1 Preliminary results of the first year confirmed that only in locations (e.g. A. Anargiroi) with sufficient initial soil POlsen contents lentil genotypes produced elevated seed yields (1.8 t ha ). Low seed yields (0.5 – 0.8 t ha ) in some locations (e.g. Larissa, Petrana) were attributed to unfavorable weather conditions during anthesis and in some cases to very high soil CaCO3 content (>25%, marl soils) which may resulted in micronutrient deficiencies, and to low initial POlsen, %TSN and CEC. Soil physicochemical properties at the beginning of crop growth is a crucial factor for obtaining profitable lentil yields under semiarid Mediterranean conditions.
