Experimental Summaries - Plant Research

CONCLUSIONS This trial has confirmed the field observation that 2,4,5-T whilst giving good initial control of Pennyroyal, fails after a number of years. Round up has a far longer term effect. This can only be attributed to a more complete initial kill as both herbicides are essentially non residual. Further work needs to be conducted on Round up in combination with soil residual chemicals or multiple applications to overcome the problem of reinfestation from seed reserves. 81A1 -01

Phosphorus Nutrition On Leaching Sands., D. M. Deeley, S. M. Mason, B. G. Barker

Experimental Summaries - Plant Research

The excessive amounts of nutrients entering the Peel-Harvey Estuarine system have resulted in a marked increase in the abundance of algal species .within the estuary and reduced production on the sandy coastal soils of the catchment from which the nutrients are being leached. Recent stream samplings by D.C.E have shown that the deep grey Bassendean sands may be contributing up to 40 per cent of the total P loading in the Harvey River. Agriculture Department trials around Albany on similar sands have shown that up to 80 per cent of the bicarb extractable P may be lost after only 150 …

Aerial Spraying Trial., G A. Pearce

Experimental Summaries - Plant Research

Conclusions 1. The volume of application with water affected the results obtained. The visual results of Treatment 1 suggested it was not an acceptable commercial result and the plant counts support this conclusion. Treatments 2 and 3 looked very similar and were very similar and were very acceptable results. 2. The height of spraying affected the results in that where the plane had to start climbing to pass over trees, the effectiveness dropped off. 3. Spray drift could be a problem because of the risk of causing damage to trees and native vegetation. Severe damage was seen on trees at …

The Effect Of Soil Acidity On Crop And Pasture Production., W Porter, R Klemm

Experimental Summaries - Plant Research

SUMMARY The effects of lime and molybdenum applications on wheat and subterranean Clover were studied further. Wheat. In relation to lime use, my aim is to develop soil tests to be used to predict when a soil requires lime to produce maximum yield, and to predict the optimum rate of lime. Using the results from field trials commenced in 1980 and 1981 the soil parameters which may be used to predict lime responses in wheat have been narrowed down. From the relationships between soil data and lime responses it appears that soil ph (measured in 1:5 H20 or 1:5 N …

Root rot resistance screening. One hundred and seven clovers selected as low in formononetin, tolerant of clover scorch, mid to late season maturity, and reasonable winter vigour were tested at two sites for root rot resistance.
