The mixture of bone meal and castor cake was therefore 

 somewhat profitable on the first two years' yield, and further it left 

 the bushes much more healthy than it found them, but the castor cake 

 alone gave an immediately profitable return. 



A similar experiment was carried out in 1900 on the Bindukuri 

 garden of the Bengal United Tea Company, on the low flat 

 land between the Tezpur bank and the river. The soil by analysis 

 was shown (see page 109) to be more or less exhausted 



Plot I was again unmanured. 



Plot 2 received 15 mds. 9 seers of castor cake. 



Plot 3 received 15 mds. 20 seers castor cake and 5 maunds of 

 bone meal. 



Tabulating the results as before, we have : 



These figures only refer to one year's crop. It is probable that 

 the effect will be felt for at least two years further, and, if so, the 

 whole increase for those two years will be obtained at no out of 

 pocket cost whatever. The manager (Mr. C. B. Taylor) reported at 

 the end of 1900 that " the strong growth and healthy condition of 

 the manured section is remarkable, and there is very little doubt that 

 these sections will give increased yields next year, and probably the 

 year after." 



It may therefore be taken that oil cake, whether applied as 

 castor cake as in the above instance, or as mustard* cake or other 

 locally produced material increases the crop to an extent which, even 

 with castor cake costing nearly 3 rupees per maund on the garden, 



Very great benefit has resulted from an application of mustard cake, locally obtain- 

 ed, in an experiment which is being conducted for me by Mr. W, N. Edwards of 

 Majulighur. The complete figures for the season are not however to hand, but I under- 

 stand the increased yield for this season alone will pay more than for the cost of the cake.
