Long Ashton Research Station

    Abstract

    THE annual report of the Long Ashton Research Station for 1943 has now been published. Several important changes in senior staff appointments mark the period covered, for Prof. B. T. P. Barker, director of the Station during its first forty years, has retired, being succeeded by Prof. T. Wallace, while Mr. A. W. Ling, though still remaining chief agricultural advisory officer in the Bristol Province, has been appointed principal of the Seale Hayne Agricultural College, Devon. The research work undertaken during the year continued to be closely concerned with current problems of the food production programme of the Ministry of Agriculture, and many useful results were obtained, only a few of which can be mentioned here. Tests made with apples, swedes, carrots and potatoes showed that ½–1 per cent naphthalene – acetic acid exerts a delaying action on bud-growth, a fact which should prove of practical importance in preventing sprouting of stored potatoes, while an allied compound, naphthoxyacetic acid, sprayed at the rate of twenty parts per million, had a stimulating effect and increased the yield of Tardive de Leopold strawberries. Outstanding results have been obtained with diehlor-diphenyl-trichlorethane (D.D.T.) as an insecticide, and the compound seems to merit field trial as a substitute for lead arsenate. Records of mineral-deficiency responses in plants have been extended, and symptoms for twenty-three new crops added to the list. As regards advisory work, a total of 10,880 letters were dispatched and forty-three papers published in scientific journals by, members of the Long Ashton, Berkeley Square and Campden staffs.
