Benefits Of Subsistence Farming. Subsistence farming merely means only being able to grow and produce enough food to sustain yourself. There really is no benefit from it other than you secure enough food for your survival. It would be very labor intensive and time consuming and you would probably have little time for other activities.
The subsistence agriculture has given way to commercial agriculture to some extent. Dry land farming is practised in areas where the rainfall is low and irrigation facilities are inadequate. Here, emphasis is laid on conservation of moisture, and on crops like jowar, bajra and pulses, which need less water.
