(h) Subterranean Clover for Soil Improvement. —An inspection was made of ail :area of subterranean clover growing as a cover-crop in a private orchard. Analysis of Soil samples at a time when nitrogen should be in optimum supply showed that the topsoil under clover contained 15-7 p.p.m. nitrate nitrogen and 24-1 p.p.m. ammoniacal nitrogen, as compared with 4-6 p.p.m. and 7-2 p.'pmi. respectively on the adjoining clean* -cultivated portion of the orchard. • (i) Rootstock Trials at Annesbrook Orchard. —The soil in this orchard is a clay loam of medium fertility. On this area Double Vigour stock (vegetatively propagated French Cxab seedling) has given better results than Northern Spy stock with the varieties Jonathan, Statesman, and Stunner. ■ (j) Raspberry Fertilizer Experiments. —ln view of the low potash status of many raspberry soils in Nelson, two fertilizer experiments have been laid down in commercial gardens in the Tadmor Valley. So far, a " complete " mixture used at 1\ cwt. per acre has given the best result, and extra potash has given no further improvement. (k) Raspberry Disease Survey. —This survey in the Tadmor-Tapawera district has been continued. The more important fungi found on unhealthy or dying plants are ;silver-leaf (Stereum purpureum), root-rot (Rosellinia sp.), Nectria, and cane-wilt (Leptosphaeria eoniothyrium). Inadequate soil drainage or damage to roots by grass-grub and -cultivation implements is in certain cases responsible for weakening the plants, thus favouring the development of disease. * (I) Raspberry Bud-moth. —A small plot of raspberries at the Cawthron Institute has been infected with bud-moth with a view to detailed studies on the behaviour of the insect audits control. , Miscellaneous Apple Dehydration.—The Fruit Section of Head Office has collaborated with the 'Chemical Engineering Section of the Dominion Laboratory in providing technical advice -and assistance to the Internal Marketing Division in connection with the commercial •dehydration of apples.
