Correct Answer: B
Solution :
Chain pump, dhekli and pulley system are traditional methods of irrigation while drip system is the modern method of irrigation. Urea, potash, ammonium sulphate are fertilisers while oxychloride is not a fertiliser. Khurpi, weedicides and seed drill are used in weeding while silos are used in storing food grains. Sowing, irrigation and harvesting are agricultural practices while hybridisation is not. 2, 4 - D, MCPA and butachlor are herbicides while BHC is an insecticide.
