Manurial Experiments. 



3. The chief work of the station is the improvement of the 

 local cotton. Incidentally a few manurial experiments were made. 

 These consisted in the treatment of (1) cotton with ammonium 

 sulphate, farm-yard manure and lime in comparison with no 

 manure and of (2) wheat with ammonium sulphate and farm-yard 

 manure separately and with both combined. In the case of cotton 

 the quantity of farm-yard manure applied was adjusted in such 

 a way that its cost was kept nearly equal to that of the special 

 fertilizer. 



The results are as below : 



Ammonium sulphate prolongs the vegetative period and so 

 the late formed bolls remain imperfectly developed and do not 

 open freely in the succeeding cold season. In the above results 

 farm-yard manure has shown a decided advantage over ammonium 

 sulphate, which fact is corroborated in the following results of 

 wheat experiments :
