Summary for Project title: R7331: Minimising the economic and
sociological impact of Phalaris minor in rice/wheat ecosystems.
Thousands of farmers in rice-wheat areas of the Indo-Gangetic Plains now
practice reduced tillage to control the weed Phalaris minor. This pest
was a major bottleneck in raising yields. Previously, farmers didn't
understand how long the weed seeds survived in the soil and what caused
them to start growing. Now, they've stopped ploughing their fields
because they know that this encourages the weed seeds to germinate.
Farmers in Haryana State and Punjab, India, successfully used low
tillage to control Phalaris. The technique has already spread throughout
the Indo-Gangetic Plains in India, Pakistan, Nepal and Bangladesh.
Besides curbing the weed, low tillage also reduces erosion, improves
soil fertility and lowers input costs—fuel, farm machinery and labour.
