Effects of salinity stress on growth, Water use efficiency and biomass partitioning of Vernonia hymenolepis in screenhouse potted soil amended with NPK 20:10:10
Abstract
Future crop production is predicted to face significant challenges from salinity stress due to secondary salinization. Therefore future-proofing crop production in these conditions is an essential path towards addressing food security. We evaluated the effect of irrigation with water of 0, 4 and 8 ppt salinity on growth, biomass partitioning, WUE and chlorophyll fluorescence of Vernonia hymenolepis A.Rich as ameliorated by fertilization with three levels of NPK20:10:10. Data were analysed for variance using the General Linear Model ANOVA procedure, after positive tests for normality and homogeneity of variance. Means were separated through the Dunnett test. Pearson Correlation was done to determine relationship between variables and these were spatially projected using the Factor Analysis procedure, without rotation. Under fertilization at 8 g NPK20:10:10 per plant, growth was stimulated by salinity increase to 4 ppt (35.43cm) compared to 30.43cm for control plants. Fertilizer application significantly improved all the biomass fractions of plants irrigated with water of 4 ppt relative to the control, while root:shoot ratios were highest for unfertilized plants indicating resource re-allocation to roots for better foraging. Chlorophyll fluorescence ranged between 0.716 and 0.727 and did not differ significantly across treatments. These values indicate that all treatments were under stress, including control plants. Values of WUE and RGR indicate that fertilization of plants irrigated with water of 4ppt salinity enhances growth and Harvest Index of V. hymenolepis, in spite of the registered stress. This is significant to future food security.
