If you have limited capital and want to see growth in companies then the first thumb rule is to avoid govt controlled companies. You can only add these companies to your portfolio considering the dividend aspect as the slightest difficulty in economy and govt bleeds these govt controlled PSUs.
A case in point is CoalIndia which has a monopoly in business and during its heydays touched 400 mark but has been in a steady decline due to govt policies. The only respite is the dividend as they pay that way to govt from the sales/profit and in return, investors get rewarded.
