6 Experiments with Humogen. 



SERIES I continued. 

 TESTS WITH DWARF FRENCH BEANS. 



The seeds were sown on June 9, eight beans per pot, the plants being 

 eventually reduced to three in a pot. The weights of the produce obtained are 

 recorded in the following table.

OBSERVATIONS RECORDED DURING GROWTH. 



June 28. The seedlings had appeared in all cases except Humogen (30%). 

 All sections dressed with Farmyard Manure and the remainder of the Humogen 

 series were the most forward. Growth seemed retarded in the Complete 

 Fertiliser test. The Rito sections were very backward. 



July 24. Farmyard manure (20% and 10%), Farmyard Manure with 

 Complete Fertiliser, and Common Burning Peat were equal in merit, and 

 were decidedly superior to either of the Humogen trials, of which the 5% 

 dressing showed the best. Humogen with Complete Fertiliser was much 

 inferior to Farmyard Manure with Complete Fertiliser. Humogen (30%) 

 and Rito (20%) were quite the worst of the series. 



August 7. All plants in flower. In the Humogen series and in the 

 plain soil Control, the colour of the foliage was extremely poor as compared 

 with sections dressed with Farmyard Manure, Rito, and Complete Fertiliser, 

 the last two being particularly dark. 



August 19. The superiority of the Farmyard Manure series and Complete 

 Fertiliser series was still maintained. The only trial containing Humogen 

 to show promise was Humogen (5%) with Farmyard Manure (10%), but 

 this was not so good as Farmyard Manure with Complete Fertiliser. The 

 plants in pots containing the smallest percentage of Humogen were better 

 than those dressed with a larger quantity. 



August 24 to September u. During this period the beans were picked. 

 The pods gathered from the Humogen sections were strikingly stunted and 

 yellow in colour.
