60 SCIENTIFIC REPORTS OF THE AGRICULTURAL RESEARCH 



1. Two plots (A and C) were sown with seed of green- 



stemmed jute about 5th March, the former with 

 treated and the latter with untreated seed. 

 The land had carried jute which was slightly 

 drained the previous season but had not been 

 under jute previously for 25 years. D. Corchori 

 was practically absent in both plots; only some 

 3 or 4 cases could be seen. 



2. In similar plots (B and D) a crop of C. olitorius 



and of red-stemmed C. oapsularis also remained 

 free from the disease. 



3. Two plots (E and F), each about \ acre, situated in 



a portion of the field in which jute had some 

 disease the previous year and was particularly 

 bad the vear before,- were sown with seed of 

 green-stemmed jute. The seed was steeped in 

 a solution of copper sulphate. Germination 

 was scanty and both plots were resown on 4th 

 July after the commencement of the rains, and 

 gave a crop of typical late sown jute, short in 

 height and thin in stem. In both plots the 

 number of stems infected with D. Corchori was 

 negligible, only about 12 cases could be found 

 when the crop was cut early in November. 

 4, Of two plots (H and K) about ^ of each plot was 

 sown on 5th March with a red-stemmed and 

 the remainder with a green-stemmed variety of 



C. capsularis. These plots were situated in the 

 land which had carried the diseased jute in 

 1918. Both the varieties of seed sown had 

 been steeped in 2 per cent, copper sulphate. 

 Plot H carried a very scanty crop and had 31 

 cases of D. Corchori among the green-stemmed 

 and only 6 cases in the red-stemmed variety. 

 In plot K the crop was much thicker, both ger- 

 mination and growth having been better than 

 in plot H. In plot K there were 190 cases of 



D. Corchori among the green-stemmed and 34 

 cases in. the red-stemmed variety.
