Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'The experiment was established in 1986 and continued until 2018 at the ICRISAT Sahelian Center (ISC), located at Sadore, 45 km south of Niamey, Niger, West Africa (lat 13' l5'N long 2' 18'E) and at an altitude of 240 m asl. The climate at Sadore is characterized by a short rainy season from June to September (about 90 d). The average rainfall is 560 mm, is irregular and normally comes in the form of thunderstorms. During the crop growing season, maximum temperatures varied in the range of 30-40oC. Potential evapotranspiration (PET) exceeds the total rainfall in all months except July-August which are the peak months of the rainy season (Sivakumar, l986). The site is located on a sandy plain with Aeolian sands 2-8 m in depth covering one of a series of stepped surfaces comprised of cemented laterite gravels (West et al., l984). The surfac' .
