Conteúdo: 	The growth response of S. humilis to six levels of phosphorus x five levels of nitrogen x three levels of potassium in association with Rhizobium.CB103 is described for plant gro-
wing in a nitrogen deficiet, light textured, solodic soil. Phosphorus greatly stimulated growth and nodulation at all levels of nitrogen addition. The effect of nitrogen interacted strongly with level of phosphorus application, with response in yield of tops to nitrogen in-
creasing with phosphorus level up to P500 (kg superphosphate/ha). The addition of ni-
trogen depressed nodulation at Po-P125 but was beneficial at P250 - P1000. Visual  ob-
servations suggested that high nitrogen checked growth initially but despite this the high nitrogen-high phosphorus combination produced the largest and best nodulated plants. 
There were only minor responses to potassium in this trial. Particular balanced combinati-
ons of nitrogen and phosphorus stimulated successful nodulation of S. humulis, enabling it 
to achieve higher yield and nitrogen content than from symbiotic nitrogen alone.
