Yield and Compositional Profile of Eggplant Fruits as Affected by Phosphorus Supply, Genotype and Grafting

The present experiment addressed the effects of two phosphorus regimes (30 and 90 kg ha?1, hereafter P30 P90) on yield composition eggplant fruits in ‘Birgah’ ‘Dalia’, whether or not these cultivars were grafted onto Solanum torvum ‘Espina’. regime did reduce yield, promoted fruits’ dry matter total phenols content, along with their concentrations macronutrients, mesonutrients (S Na) micronutrients (mostly Cu, B, Zn); however, Fe depressed. rootstock ‘Espina’ increased fruit epicarp chroma (in ‘Birgah’) Ca together B Zn (especially at P30), but reduced mostly under P30. Thus, P supply grafting proved to be effective tools enhance carpometric almost all nutritional traits eggplant, a framework more sustainable crop management. However, concentration suggests that affinity specific micro minerals should taken into account, option adopt complementary practices (e.g., targeted micronutrient fertilizations) manage mineral eggplants.
