Naranjilla, Solatium quitoense, was successfully cleft grafted on to S. macranthum. Cherimoya, Annona cherimola, was successfully grafted on to A. squamosa, A. reticulata and A. montana. In germination tests on macadamia nuts a 50-50 mixture of screened peat and sphagnum moss and a sterilized,...

Statements are made on fruit production in districts for both deciduous and citrus and other subtropical fruits, i.e. Chinese gooseberries, tree tomatoes, passion fruit and feijoa. The approximate areas under different vegetables are noted. The area under hops in 1948 [almost entirely Waimea...

Studies with Valencia orange indicate that N was the only element that could be directly related to fruit production. P, K and Mg in the amounts used did not appear to limit fruit production directly, but P and K may have had secondary effects. Fruit production in groves with inadequate moisture...

The following among investigations affecting horticultural crops may be noted briefly: Fruit and nut insects: Progress on oriental fruit fly research; the effect of parathion in controlling purple scale and advancing maturity in oranges; the vapour-heat sterilization of citrus fruits to kill...

The various copper fungicides applied to two varieties of orange and one of grapefruit were about equally effective in controlling melanose, Diaporthe citri. Late treatment with copper sprays was, however, found to be undesirable. It 'appears that copper, applied to fruit on which melanose lesions...

Research included breeding and selection of new male parents, taxonomy of edible bananas, bract pigmentation, physiology of fruit development and cytogenetical studies.

For the purpose of greater efficiency a complete separation of the horticultural, inspectorial and advisory services has taken place. Acreages under pome, stone, berry and citrus and other sub-tropical fruits are given with some production figures. Plant protection of all fruits is dealt with;...

In a 5-year trial water containing 1 ton of salt per acre-ft. was applied at 6, 10 or 14 ft. per year and N was applied at 0, 8 or 13 lb. per tree per year. Conductivities of the saturation extracts were 3 millimhos per cm. for the 14-ft. water supply and 4-7 for the 6-ft, the 10-ft. being...

"The primary object of the scheme was to combat panamá disease of the Gros Michel banana by the combination of pathological and plant breeding techniques. As time has gone on, it has become evident that control of leaf spot is, for Jamaica, at least as important as control of panamá disease in...

Nutgrass, Cyperus spp., often forms dense sods.in date palm gardens, but older deep-rooted palms do not appear to suffer from this competition. When old palms are grubbed, however, the nutgrass may have to be eradicated before the land can be used for other permanent crops. Several trials with...
