Time Of Planting And Rate Of Seeding On Lupin Yield, G Walton

Experimental Summaries - Plant Research

Of the four time of planting trials twodefinitely showed superiority of earlier seeding (73BA5, 73E6). The two trials in the Southwest (73BR14 and 73MT7) gave highest yields with June sowing compared to May. Three trials (73BR14, 73E6 and 73BA5) appear to have a Variety x Time interaction for plant density, but no definite trend for either Uniharvest or Unicrop although later sowing reduced plant density. Seeding rates in excess of 82 kg/ha gave the highest yields in all trials. The rate of seeding experiments (73BA5 and 73MT7) show that the best crop density for yield (graph) lies between 8 and …

1973 Legume Seed Inoculation, D L. Chatel

Experimental Summaries - Plant Research

Lupin Experiments - Eleven trials were sown during 1973 with the aim of further examining the response of lupins to inoculation on old clover land, new to lupins, and some on new land. The lime pellet and gum slurry methods were compared. The opportunity was also taken to compare a new rhizobia, WU8, with the current commercial inoculant WU425. 1. Inoculation of Uniharvest lupins - time of sowing, strain of rhizobia and method of inoculation. Sown as second crop on old clover land - WILLIAMS. 2. Inoculation of Uniharvest lupins sown as a first crop on old clover land - …

1973 Rates Of Phosphate On Lupin Yield, G Walton

Experimental Summaries - Plant Research

Comments on results New land sites (Graphs 1 & 2) The three sites were very responsive with the point of inflexion about 600 kg/ha super rate (similar to 1972 result). The seed x super rate interaction shows the quicker response to super with .higher seeding rates. Low super bank (800 kg/ha) (GRAPH 3) The two sites showed very little response to super applied. On the Eradu sandplain no response to super for either Unicrop or Wheat. On the Watheroo yellow sandplain ( 73M015) the two lupin cultivers and the wheat gave different responses. High super bank ( >1 OOOkg/ha) (GRAPH …

Objective Measurement And The Stud Breeder, B R. Beetson

Journal of the Department of Agriculture, Western Australia, Series 4

The movement towards sale of wool by certificate and sample highlights the significance of objective measurement in the Merino stud breeders' selection of his top rams.

This article suggests how stud breeders should use the Department of Agriculture's Flock Testing Service to gain genetic progress in wool producing ability without loss of visual buyer appeal.

Studs' use of the service will be evaluated in 1974.

A Geochemical Study Of A Marsh Environment, Thomas F. Lytle, Julia Sever Lytle, Patrick L. Parker

Gulf and Caribbean Research

The goal of this study was twofold: 1) chemically to characterize a specific salt marsh, the sediments and associated biota and 2) to establish clear relationships between the chemical substances residing in the sediments and similar or identical substances occurring in the biological specimens. In this particular study it was felt that the hydrocarbons would yield the most significant organic geochemical information. These compounds are ubiquitous but minor components of all organisms. Though their function is not entirely understood, it is known that they are concentrated in the waxy coatings of plants and most likely aid in the protective mechanisms …
