Data from vegetable crops grown under high soil water availability in Mediterranean greenhouses

The hypothesis of these data (tables and figures) is: a higher irrigation frequency of soil-grown vegetable crops in Mediterranean greenhouses will improve crop yield and quality? The soil water availability of six vegetable crop cycles was modified by varying the irrigation frequency in typical Mediterranean greenhouses at SE Spain. The soil matric water potential (SMP) in the middle of the loamy soil layer where most roots usually grow was maintained between −10 and −20 kPa (H), −20 and −30 kPa (C), and −30 and −50 kPa (L) for the crops grown under high, conventional and low soil water availability, respectively, while the total irrigation water applied was similar for the three treatments. The high soil water availability (H) did not improve the fresh weight of total, marketable and first class fruits, or the shoot biomass and partitioning.
