Mineral profile of tomato, cabbage and brinjal irrigated with canal water and sodic water treated with gypsum and farm yard manure

This study was aimed to find out the variation in total and HCl-extractable mineral composition of tomato, cabbage and brinjal irrigated with canal water and sodic water treated with gypswn and farm yard manure (FYM). Vegetables grown Wlder soil irrigated with canal water (control) and soil irrigated with sodic water treated with gypswn and FYM at two different levels i.e. 50% neutralization of sodicity (GF₂) and complete neutralization of sodicity (G₂F₂) were obtained from the Vegetable Research Farm, CCS Haryana Agricultural University, Hisar. Total and HCl-extractable minerals were analysed in acid digested samples. ANOVA was done to determine differences in mineral profile of vegetables grown under three different water treatments. Vegetables irrigated with G₂F₂ (100% neutralization of sodidty) treated water and canal water (control) had higher (P<0.05) amounts of total and HCI-extractable calcium, magnesium, phosphorus, potassium, iron, zinc and sulphate but lower amounts of sodiam and chloride than the vegetables irrigated with G₁F₂ (50% neutralization of sodicity) treated water.
