ITR filing : Clarification of 50 Lakh Income Clause

Dear All, 

Income tax filing clause mentions that if your income is above 50 Lakh then you will have to file ITR 2. But it is not clear which value within the ITR2 if goes above 50 Lakh then you will file ITR 2. These are tax paying individuals whose income is just on the boundry of 50 Lakhs and gets above or below 50 Lakh depending on the deductions u/s 10 , Interest Income and Deductions under VI-A. 

so , please inform which value in below fields in ITR if goes above 50 Lakh then we continue with filing ITR 2. Basically, which field we should refer for income above 50 lakh clause. Income is mainly from Salary and Savings bank interest.
