Abstract
The Customized Fertilizer Formulation (CFF) applications on growth and yield of Brinjal (Solanum melongena L.) varieties Manaparai local and CO-2 under sodic soils were studied with eleven CFF combinations. No Significant observations in growth yield and yield parameter was recorded due to the combined application of CFF and organic amendments on sodic soils. The symptoms of salt injury were well pronounced in brinjal cv. Manaparai local when compared to brinjal cv. CO2 though the sodic soil reclamation was done with gypsum @1.1 t/Ha. The salt injury was further confirmed with electrolyte leakage study conducted at field level. However, the treatment T11 i.e. CFF2 100% macro nutrients as straight fertilizers, liquid micronutrient formulation and composted Press mud @ 5 t/ha was found to have the brinjal fruit yield of 1.39 t/ha in cv. CO2 which was not a desirable yield. This might be due to the yield reduction per unit increase in salt content.
