Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'The data sets reveal grain Zn biofortfication performance of Zn-efficient and Zn-biofortified rice genotypes grown in different seasons in contrasting soils. Specifically, This study investigated grain yields and grain Zn concentrations of Zn-biofortified rice genotypes compared with Zn-efficient and -inefficient genotypes in field experiments in the Philippines in four contrasting paddy soils: one Zn-sufficient and three Zn-deficient with deficiency associated with (1) strongly reducing conditions and high soil organic C content; (2) high soil pH and presence of free calcium carbonate; and (3) strongly-weathered soil. In wet season 2012, results revealed that Zn-biofortified genotypes achieved both grain yield (4.0 t ha-1) and grain Zn  concentration (30 mg kg-1) targets compared with Zn-efficient, Check and Zn-inefficient genotypes whe' .
