In partnership with the Columbia Water Center, researchers from Punjab Agricultural University have initiated a multi-year project to implement and field-test diverse water-saving technologies, practices and policies aimed at reducing agricultural water use in the state of Punjab, particularly among rice farmers. In last year’s trial, the most successful project involved the installation of inexpensive tensiometers in the fields of over 500 farmers, yielding water savings of 30-35 percent.

Concurrently with the tensiometer trials, the team also recruited a smaller number of farmers to adopt a different way of cultivating rice altogether: Direct seeding of rice.

In traditional rice cultivation, rice is sprouted in a nursery; sprouted seedlings are then transplanted into standing water. With direct seeding, rice seed is sown and sprouted directly into the field, eliminating the laborious process of planting seedlings by hand and greatly reducing the crop’s water requirements.

Conventional rice production requires standing water
