RESULTS OF WINTER CEREAL EXPERIMENTS AT 

 THE SCHOOL OF AGRICULTURE, ELSENBURG, 

 MULDER'S VLEI, CAPE PROVINCE. 



By T. G. W. Reinecke, Principal, and G. -J. Meynhardt, 

 Assistant Experimentalist. 



Cereal investigations have been carried on at tlie School of Agri- 

 culture, Elsenburg, for several years. Unfortunately, owing- to the 

 hilly nature of the farm, the soil is of varying composition and depth. 

 It was found extremely difficult to select a site for the Experimental 

 Division where the soil was sufficiently uniform to yield comparable 

 and reliable results. The present site is, according to the records, 

 the third one selected since the founding of the school. Work was 

 commenced on this site in 1915. Even here it soon became apparent, 

 in the case of the fertilizer trials, that the number of check plots 

 provided was totally inadequate to eliminate the effect of soil 

 differences. 



The investigations in progress embrace the following: — Rotation, 

 soil fertility, fodder, seeding experiments, and variety trials. 



ROTATIOX AXD SoiL FERTILITY EXPERIMENTS. 



Ca) Comparative Valves of Various Crops as Crreen Manures. 



These trials were commenced in 1915. The following has been 

 the rotation practised and the fertilizer treatment applied: — 



1918 ... Wheat ... ... 75 lb. Superphosphate. 



75 lb. Government Guano. 



1919 ... Oats ... ... 75 lb. Superphosphate. 



75 lb. Government Guano.
