A growth disorder of cotton has been observed in irrigated cracking clay soils in fields at Galathera Creek, north of the Australian Cotton Research Institute (ACRI) for several years.

This report arises from a scoping brief presented to the author on 19th May 1995.

Frontiers of Population Ecology Meeting program and abstracts

In March 1995 I attended two Keystone Symposia, "Frontiers of Plant Morphogenesis" and "Signal Transduction in Plants", held concurrently at Hilton Head Island, South Carolina, U.S.A.

Cotton fibres are differentiated from single ovule epidermal cells and grow synchronously, initiating at about the time of anthesis.

The cotton plant has two main sets of traits that contribute to its resistance to pests: (1) chemical (e.g. gossypol) and morphological defences (e.g. okra-leaf) and (2) compensatory mechanisms for regrowth (e.g.

Annual Report 1994-1995

This report summarises the findings from the CRDC funded project "Managing soils to avoid compaction problems in cotton growing". The project ran from 1989/90 to 1991192.

A growth disorder of cotton ( Gossypium hirsutum) occurs in irrigated cracking clay soils in cotton growing regions of northern New South Wales.

Vertosols are the main soil type on which cotton is grown in Australia. Eighty percent of irrigated cotton is grown in retained hill.

OBJECTIVES: 1. To study sampling and control practices for mirlds in irrigated and dryland cotton.

Project Objectives: Part A: (i) To study the effect of wet/dry cycles with drying by evaporation alone in ameliorating degraded furrows in retained hill cotton (at the Fressor site).

The conference was held on the 23 - 27th of August, 1994 in Silsoe, UK.

There are both anecdotal and well documented reports indicating that unsprayed cotton can be profitable.

The Total Catchment Management ("TCM'') philosophy was formalised in NSW in 1980 with the passing of the Catchment Management Act which provides a clear legislative base for the operation of TCM Committ

Watertable rises resulting from irrigation are evident in several areas in the Murray Darling Basin, with groundwater level rises of up to 70 cm per year being reported in the Riverina and 50 cm in the Lower Macquarie

In this article I will chiefly focus on the this problem on soils with adequate levels of soil potassium.

Raingrown cotton is becoming a very important component of the Australian industry: the relative proportion of the crop grown with rain has been increasing over the past ten years.

In 1994, the Australian cotton farmer must use a wide range of costly chemicals to harvest a profitable crop. These chemicals vary significantly in their degree of hazard. Some chemicals (e.g.

In recent years Cotton Seed Distributors (CSD) have made available a range of CSIRO varieties with different attributes, thus enabling farmers to choose varieties best suited to their particular situation.
