Vishishta Composting: A Fastest Method and Ecofriendly Recipe for Preparing Compost from Parthenium hysterophorus Weed

Introduction: Parthenium hysterophorus has become a huge problem throughout the world and is menacingly threatening the agriculture and environment. The existing methods for controlling or eradicating P. hysterophorus weed have their own limitations, that is, physical methods are very laborious, costly and ineffective in long term; chemical methods are costly and less environmental friendly and biological methods are not appropriate on large scale. The compost from Parthenium weed can be prepared to recycle the nutrients that are sucked by undesired weed from the soil. Presently, the available methods take a long time in preparing Parthenium compost, while the shorter methods are mostly less ecofriendly. In the present work, a method and recipe have been developed for preparing compost of Parthenium weed in comparatively less time (60 days only) and that too, in an ecofriendly manner; and it has been named as Vishishta composting. The term ‘Vishishta’ is a Hindi word, which means ‘something special’. Materials and Methods: In the present experiment, Parthenium weed was composted using rock phosphate, Trichoderma viride fungi culture powder and different organic wastes such as cow dung, sawdust, cow dung ash, dried fallen leaves and wheat straw in a duration of 60 days using the method of Vishishta composting. Results: The P. hysterophorus compost contains more nitrogen, phosphorus and potassium and other nutrients than farmyard manure. Overall status of the nutrients as-prepared compost is appreciable. Conclusion: In the present experiment, a method and recipe have been developed for composting Parthenium weed in shortest duration as compared to earlier methods available till date.
