Four barley varieties responded with increased grain yields to fertilizer application only when the water supply was adequate. When the supply was restricted throughout the period from tillering to harvest, grain yield was less with fertilizer than without. Changes in 1000-grain weight were similar to those in yield. Rod 205 was the most responsive in respect of grain yield and Diamant the most sensitive to drought.Four out of five wheats showed a similar pattern of response to that of the barley varieties, though more extreme; their yields were less with fertilizer than without even after a shorter period of drought (from tillering to earing). The hybrid Rokicka X Golden Ball was the most sensitive.
