ICAR stubble burning solution shows promising results at trials in Delhi, Punjab

A proprietary microbial resolution developed by the Indian Council of Agricultural Research (ICAR) might be a breakthrough within the hunt for an answer to crop-residue burning, a significant explanation for winter air pollution in north India, outcomes from trials in Delhi and Punjab present.

“The ICAR’s invention, named Pusa, decomposes crop residue, including paddy straw, and turns it into manure in about 25 days, thus eliminating the need to burn paddy stubble. It could be a breakthrough if adopted with an integrated approach,” YV Singh, principal scientist of microbiology at Indian Agricultural Research Institute (IARI), advised HT.

Singh stated the know-how had an efficacy vary of 70%-80%, citing outcomes from its use in 24 villages in Delhi this October. This means it might probably efficiently decompose as much as 80% of the straw in a given space.

The Delhi authorities adopted the know-how from IARI to stop burning of paddy stubble in about 700 hectares of rice fields, a venture that value Rs20 lakh.

The institute has utilized for a patent for the know-how and is within the strategy of signing contracts with personal corporations to commercially market the product, Singh stated.

Assuming farmers in Punjab burn paddy straw in at the least two million hectares, it’s going to value the state Rs571 crore to fund the usage of Pusa decomposer to eradicate stubble burning, HT’s calculation primarily based on the Delhi authorities’s prices present.

Farmers throughout Punjab, Haryana and Uttar Pradesh sometimes harvest paddy in October after which set their fields on fireplace to clear rice stalks for the subsequent crop. It is the quickest and most cost-effective solution to clear the fields of undesirable stalks.

The burning of greater than seven million hectares of crop residues has emerged as one of many largest sources of winter air pollution, leading to weeks-long smog in New Delhi each October and November.

Burning paddy straw has emerged as a giant downside prior to now two to 3 a long time as farmers have shifted to mechanised mix harvesters, which lower the grainy a part of a rice plant, leaving the stalk intact.

While the straw from basmati rice, which is usually exported, is delicate sufficient for use as fodder, the residue of different rice varieties, which account for many paddy acreage, is just too stiff to be of any use. Farmers say they’ve few efficient, inexpensive options to burning.

Pusa decomposer comes within the type of capsules that include an activated package deal of eight strains of fungi, Singh stated. To put together an answer of 25 litres, farmers want so as to add 4 capsules of the decomposer, together with jaggery and checkpea flour, to water. Within every week, a superb layer of fungi admixture is shaped. To decompose paddy stubble in a single hectare, farmers must spray 25 litres of this resolution.

According to A. Amarender Reddy, the principal scientist on the Central Research Institute for Dryland Agriculture, microbial brokers within the resolution act on the straw to make it delicate, break down its elements and launch vitamins into the soil.

The IARI is making an attempt to popularise its resolution in Punjab and Haryana, the place farmers have used it in about 12000 hectares, which is only a fraction of the overall rice acreage. “Some form of subsidy may be needed to popularise its use,” stated Singh stated.

The farm ministry already runs a programme known as “Promotion of Agricultural Mechanization for In-Situ Management of Crop Residue in the State of Punjab, Haryana, Uttar Pradesh & NCT of Delhi” with funds value Rs1,151 crore from 2018-19 to 2019-20 to subsidise equipment wanted for administration of crop residue. According to information from the Punjab Remote Sensing Centre, the state witnessed 40,000 incidents of farm fires on November 5.

Five years in the past, the National Green Tribunal, an environmental court docket, banned stubble burning. Punjab authorities high-quality farmers in the event that they defy the ban however such coercive strategies have proved to be of little assist.
