Dear Sir
Vegetable such as cucubitaceius crops such as bottle gourd, ridge gourd, snake gourd, coccinea, chow chow, pumpkin, beans can be easily grown in half an acre.
Are these for ur use or for selling purpose.
generally leguminous crops such as beans, peas, have nitogen fixing ability in their root nodules and can regenuvate ur soil. U can also cultivate marigold at the corners or a boundary as these will restrict nematodes.
