From the statements given it is probable that neither spraying 

 nor steeping has had any effect but that the differences in the 

 yields of the plots are due to differences in the soil. 



The yield on the average decreases from west to east and this 

 may be due to the fact that on the west was a heavily watered plot of 

 Guinea grass or that the soil to the east is more seriously infected. 



9. Wilt disease of Tur. All the nine varieties of Tur, which 

 had shown some resistance to the disease last year, were grown on 

 the same piece of land. Out of the nine varieties six have shown 

 a higher percentage of resistance this year than last year, and 

 one has remained the same. The variety Sambalpore No. 9, 

 which had shown above 78 per cent, of resistance last year, has 

 gone down to 48 this year, while the last year's second best 

 Bilaspur No, 1 has increased in its percentage to 70. These 

 results are probably due to variations in soil and season and not to 

 any quality inherent in the varieties. 



The statement below shows the counts taken, the percentage 

 of resistance arid yield per plant of the nine varieties :
