This repeated experience with so free-growing a crop as Lucerne has 

 led us to make some experiments to see whether nitrogenous manure in 

 the form of nitrate of soda would have in ordinary market-garden practice 

 any appreciable value for some of the ordinary vegetable crops — Peas or 

 Beans — belonging to the same family. The results of our experiments 

 up to the present year are here given. 



Dwarf French Beans. 



We have now grown this crop for three seasons. In each season two 

 plots were devoted to the crop, both receiving London dung at the rate 

 of 25 loads (or 12^ tons) per acre, together with a dressing of 6 cwt. of 

 superphosphate per acre. One plot received no nitrate of soda ; the other 

 was dressed with nitrate at the rate of 2 cwt. per acre. 



The following table shows the results of the three years, together with 

 the average. 



The individual Bean pods were plucked green day by day as they 

 attained what was considered to be the best market size and condition.
