DRIS Norms and Sufficiency Ranges for Pepper Grown under Greenhouses Conditions in the Southeast of Spain

The aim of this study was to compile DRIS (Diagnosis and Recommendation Integrated System) norms sufficiency ranges for pepper grown in greenhouses the determination variation during different phenological stages crop. were constituted by 367 leaf samples Capsicum annuum L. which collected crop (flowering (FL), fruiting (FT), fruit development (FD), harvesting (HV)). Two developed; one including all other considering ((FL) (44), (FT) (96), (FD) (100), (HV) (127)). Furthermore, 10 CV calculated from N, P, K, Ca, Mg. ratios them FL (N/P N/K), two FD Ca/N) HV (N/P) showing low CV, meaning, according norms, essential role these nutrients nutrition. Moreover, computed database were: N (34–56), P (1.9–4.3), K (30–51), Ca (12–33), Mg (4.0–15) (mg g?1 DW), respectively. data obtained experiment highlighted importance sensitivity (low CV) nutrient such as happened with N.
