Combined Effects of Drought and Soil Fertility on the Synthesis of Vitamins in Green Leafy Vegetables

Green leafy vegetables, such as Vigna unguiculata, Brassica oleraceae, and Solanum scabrum, are important sources of vitamins A, B1, C. Although vitamin deficiencies considerably affect human health, not much is known about the effects changing soil climate conditions on vegetable concentrations. The high or low fertility three drought intensities (75%, 50%, 25% pot capacity) plant species were analysed (n = 48 pots) in a greenhouse trial. fresh yield was reduced all vegetables result lower during severe drought. concentrations increased with increasing stress some species. Regardless, total yields showed net decrease due to significant biomass loss.
