A white button mushroom producer since 1996, Jeetender Mallik (38) of Seenkh, Panipat, Haryana developed an electricity-operated compost making machine for mushroom cultivation in 2008. His machine with two motors (one for rotating the blades and the other to power the rear wheels) can turn and mix the compost, remove lumps and add moisture and prepare good quality compost in less time. With a single operator, it can complete a 200×4×4 ft heap in 25 min.
Apart from this, he has also made a sieve for casing soil for mushroom cultivation, a manual drill to make holes for putting bamboos for erecting bamboo shades, a mobile electric motor operated hole digger and a machine for turning dry compost on the ground. He won the NIF Award (National Second – Agricultural Engineering) in 2015.
