MUMBAI: India's soyabean production is set to jump by at least 15% in 2020 from a year earlier as farmers are increasing the oilseed's acreage due to timely arrival of monsoon rains and as New Delhi raised the minimum buying price.

Increased production of India's main summer-sown oilseed could help the world's biggest vegetable oil importer trim costly purchases of palm oil, soyaoil and sunflower oil from Indonesia, Malaysia, Argentina and Ukraine.

It could also revive Indian exports of animal feed ingredient soyameal to places such as Bangladesh, Japan, Vietnam and Iran.

"Farmers are expanding area. If monsoon remains good, I am expecting at least 15% rise in the output," said Angshu Mallick, deputy chief executive of Adani Wilmar, a leading edible oil refiner.

Farmers have planted soyabean on 10.15 million hectares as on July 10, compared with 5.17 million hectares a year earlier as the monsoon covered the entire country nearly two weeks earlier than usual, according to the farm ministry.

India produced 9.3 million tonnes of soyabean in 2019.

The central state of Madhya Pradesh and Maharashtra in the west account for more than 80% of India's total soyabean output. Both states received 15% above average rainfall since the start of monsoon season on June 1, weather department data showed.

India raised the minimum buying price for soyabean by 4.6% from a year earlier to 3,880 rupees per 100 kg, even as prices came under pressure in the last few months due to weak demand for soyameal from poultry industry.

The bumper crop would put additional pressure on local soyabean prices as the country is expected to start the new marketing year with carry forward stocks of 1.28 million tonnes, up from 170,000 tonnes a year ago, said Davish Jain, chairman of the Soyabean Processors Association of India.

"Local demand is weak and soyameal exports are not picking up. The government needs to restore 10% incentive for soyameal exports to support soyabean prices," Jain said.
