Farmers engaged in mushroom cultivation in Jammu and Kashmir are upbeat over the government announcement to introduce one of the costliest mushrooms 'Shiitake' for commercial farming in the Union Territory. The agriculture department will launch commercial farming Shiitake in September after successful field trials of the cultivation of this Japanese-origin variety. "We are happy. I have heard it (Shiitake mushroom) is being launched in September (for commercial farming). We will go for it," Mushroom farmer Rahul Sharma told PTI. Sharma, who owns a 4,000-bag unit in the border belt of Marh, said that it is grown in states like Haryana, but it is good news that it will be grown in Jammu for the first time.
