LETTUCES AT WISLEY, 1919. 



About two hundred and eighty stocks of Lettuce were sown at Wisley 

 for trial in the spring of 1919. The ground on which the Cabbage 

 Lettuces were sown had carried a crop of peas in 1918 ; after they 

 were removed a dressing of pig manure was applied and the ground was 

 dug. One row of seed (36 feet long) of each stock was sown on April 4. 

 The drills were 2 feet 6 inches apart, and on May 12 sufficient seedlings 

 were removed from each to form another row, so that the rows were 

 finally 15 inches apart and the plants a foot apart in the rows, the 

 final thinning being done on May 16. The land used for the Cos 

 Lettuce had borne a crop of Climbing Beans in 1918, but was otherwise 

 similar to the Cabbage Lettuce land and was prepared in the same 

 way. The seed was sown on May 5 and seedlings were transplanted 

 on May 26, the treatment being exactly the same as for the Cabbage 

 Lettuce except that the transplanted rows were watered twice w r hereas 

 the Cabbage varieties received no water. The ground was hoed 

 frequently during the trial, and the plants almost without exception 

 grew well. The rainfall during the period covered by the trial was 

 very small, but the constant presence of a mulch of loose soil on the 

 surface prevented the soil from becoming too dry. The rainfall 

 measured was, for April 2-48 inches, May -24 inch, June 1-17 inch, 

 July 2-66 inches. 



It is to be noted that the transplanted plants were markedly 

 behind those allowed to remain where the seed was sown, being at 

 least a fortnight later in reaching maturity in most cases. The rate 

 with which they ran to seed was not noticeably greater than that 

 of the sown row. For other notes see under the different sections.

 occasions and made the following recommendations for Awards : —
