AROMATIC PLANTS 



At the beginning of the experiment each plot received the dressing 

 of dnng that is usnally used in the district, and in addition the fohowing 

 manures were apphed per acre. 



riot I. Xo artificial manure. 



Plot II 115 lbs. sulphate of aninionia + 2(-)b U)s. superphosphate. 



Plot III 113 lbs. sulphate of ammonia -f 266 lbs. superjihosphate + 132 lbs. po- 

 tassium salts (40 per cent). 



Plot I\' 115 lbs sulphate of ammonia + 266 lbs. super])hosphate + 203 lbs. potassium 

 salts (40 per cent). 



With 1920 plants to the acre, each plant receives : 



Plot II 0.19 oz. nitrogen + 0.40 oz. phosphoric acid. 



Plot III 0.19 oz. nitrogen + 040 oz. phosphoric acid + 0.44 oz. potassium. 

 Plot IV 0.19 oz. nitrogen + 0.40 oz. phosphoric acid + 0.68 oz. potassiimi. 

 The farm j-ard manure was applied at the rate of 2 1/4 to 3 ^ ^ lbs per plant, and the artifi- 

 cials were spread from the end of March to mid-April. 



The following are the details of the cultivaticjn and the description 

 of the soils used.
