The report of work on vegetables under Mr, Arturo Riollano includes 
discussion of an experiment in tomato pruning and staking, pp. 156-157. 
It is recommended in conclusion "for the farmers of this region to 
grow tomatoes without staking and without pruning. These practices 
have been shown to be detrimental to production, besides increasing 
the expenses of labor operations." 
Results are given (p. 157) of a tomato (organic matter) test which 
was held "to determine the effect on production of applying organic 
matter in the form of filter press cake at the rate of 12 tons per 
acre."
