Summary

Numbers of eelworms in soil before and after fumigant treatments - Residual effects. This dataset consists of the plan, treatments, cultivations, yields and numbers of eelworm cysts relating to the fumigation Experiment conducted in Pastures at Rothamsted. then Experimental Station, in 1936, following on from 1935.

Methods

Two random samples of 50 grms soil were taken per half plot Dec 1 and 2 and third cysts count made.

Technical Information

Area of each plots: 1/80 acre (30lks. X 41.7 lks.). Treatments: No fumigant (O), single (1) and double (2) dressings of "cymag" (CM), carbon disulphide jelly (S), chlordinitrobenzene (N) and "seekay" (CK), at the following rates of application per acre for the single dressing: 1 CM, 7.5 cwt.; 1S, 24.3 cwt.; 1N, 2.0 cwt. and 1CK, 5.0 cwt., applied in 1935. Sulphate of ammonia (A) at the rate of 0.4 cwt. and 0.8 cwt. N per acre, applied in 1936. Basal Manuring: Nil. Cultivations, etc: Ploughed: Aug. 27-29 and Feb. 10-March 13. Spring-tine harrowed: March 19. Rolled, harrowed, sulphate of ammonia applied and drilled; March 20.. Harrowed: May 8. Rolled: May 9. Harvested: Aug. 7. Variety: Marvellous. Previous crop: Oats. (See 1935 Report, p. 176). Special Note: The entire produce was weighed, Oats plus weeds. Weight of oats was determined by sampling a strip 30 lks. X 1 yd. Third cysts count; Dec. 1 and 2. Two random samples of about 50 grms. of soil were taken per half plot. Standard Errors per plot: Weeds: 22.4 cwt. per acre or 19.8%. 3rd cyst count: sampling error 32.3 or 16.6%; experimental error 59.9 or 30.7%.
