Agronomic biofortification of calcium in cabbage (Brassica Oleracea var capitata) applied with different sources of liming in Ca deficient acidic soil of Coonoor, The Nilgiris (Typic Dystropept)

The human body needs calcium (Ca) to maintain strong bones and teeth build a structure, helping muscles contract playing crucial role in the structural signalling process. However, low consumption diet has related variety of disorders humans, which can have long-term health repercussions. Therefore, this study aimed evaluate Ca biofortification capacity cabbage (Brassica oleracea var capitata) supplied with different Ca-supplying inorganic fertilizer sources at various fixed levels based on soil liming potential grown open field conditions where four hybrids deficient acidic soil. applied as Limestone (CaCO3) (150% 175% potential) Dolomitic limestone [CaMg(CO3)2]150% yield high content head foliage (61.3 mg 100 g-1), glucosinolates (53.12 g-1) lower oxalate(0.31 that produced firmer compared untreated control also promoted market value for biofortified ones. On other hand, addition leads Fe Mg tissues due an antagonistic effect. All studied using agronomic method significantly(p≤0.05) improved enrichment (20% more control) without showing any toxicity symptoms making possibility obtain hilly ecosystem by application liming.
