Take a metro line "A" to the "Dejvická" terminal, climb the stairs towards Sedlec (no escalator, just a staircase). Bus stop for bus 107 or 147. Both lines have a stop named "Zemědělská univerzita". Get off at this stop and walk across the nearest major intersection towards the University campus. Go straight up to the Faculty of Agrobiology, Food and Natural Resources (yellow building).
