Thirty-one papers reporting progress of research on avocados during the 1991-92 season are presented in this issue. The papers are concerned with various aspects of economics, breeding and cultivars, propagation, management (including orchard groundcover species), nutrition, chemical and biological ...

This volume contains 38 papers reporting progress of research on avocados during 1993. They deal with aspects of economics, breeding and cultivars, rootstocks, management, nutrition, chemical and biological control of pests and diseases, physiology, fruit storage and marketing. Two of the papers...

This volume contains 37 papers on various aspects of avocado research including breeding programmes, rootstock trials, crop protection, cultural methods and postharvest systems.

This booklet contains about 150 abstracts of papers presented at the 10th entomological congress of the Entomological Society of Southern Africa, held at Grahamstown in July 1995. A wide range of entomological topics are dealt with including some on the biological control of weeds and arthropods;...

The effects of N, P and K on Pinus radiata were investigated by growing plants in pots filled with two typical forest soils from the Western Cape of South Africa. Significant interactions were found. On soil A, a coarse sand from Grabouw, no significant growth response was obtained without the...

Avocado cv. Fuerte trees on Duke rootstock, planted in 1978, were studied in 3 separate NPK manuring experiments [details not given]. Each year (1984-87) 6- to 8-month-old leaves were analysed for N, P, K, Ca, Mg, Zn, Cu, Mn, Fe and B and the relationships were determined between increasing foliar...

Describes the work of the D. R. de Wet Tree Breeding Station, founded at Sabie in 1958, which concentrates on Pinus patula, P. elliottii and P. taeda. A Pine station was established in 1961 at Dukuduku, Zululand, and a third is projected for Saasveld in the Cape. A Eucalyptus station has also been...
