  • Zero-till Wheat Raises Farmers’ Incomes in Eastern India, Research Shows

 

Farmer-with-wheat-harvestNEW DELHI, India (CIMMYT) — In a study published last month in Food Security, researchers from the International Maize and Wheat Improvement Center (CIMMYT) reported that wheat farmers’ total annual income increased by 6% on average with the introduction of no-till farming method in the eastern Indian state of Bihar.

While studies done in the past have shown the impacts of no-till farming in field trials or controlled environments across South Asia, this research is believed to be the first that studied actual impacts in farmers’ fields in eastern India.

“We found that the prevailing no-till practice, without full residue retention, used by farmers in Bihar has led to an average yield gain of 498 kilogram per hectare (19%) over wheat sown by conventional tillage method,” said Alwin Keil, Senior Agricultural Economist, CIMMYT and the lead author of this study.

The no-till practice allows farmers to plant wheat directly into residues of the previous crop without ploughing, thus helping save irrigation water, increase soil organic matter and suppress weeds.

According to the study, large-scale adoption of no-till wheat production could play a major role in making eastern India self-sufficient in wheat.
“It’s important to enhance the productivity of the rice-wheat cropping systems in the Indo-Gangetic Plains for ensuring food security for more than 20% of the global population,” highlighted Keil.

Prone to floods and drought, Bihar has the lowest wheat yields in the Indo-Gangetic Plains with an average of 2.14 tons per hectare. “To feed a growing wheat-consuming population, Bihar currently imports wheat largely from the northwestern state of Punjab, where yields have stagnated over the last five years due to an over-exploitation of resources, especially water,” said Keil.
