Effects Of Fallow Replacement Crops On Wheat And Grain Sorghum Yields, J. Holman, A. Obour, T. Roberts, S. Maxwell

Kansas Agricultural Experiment Station Research Reports

Interest in replacing fallow with a cash crop or cover crop has necessitated research on soil, water, and wheat yields following a shortened fallow period. Fallow stores moisture, which helps stabilize crop yields and reduces the risk of crop failure; however, only 25 to 30% of the precipitation received during the fallow period of a no-till wheat-fallow rotation is stored. The remaining 75 to 70% of precipitation is lost, primarily due to evaporation. Moisture storage in fallow is more efficient earlier in the fallow period, when the soil is dry, and during the winter months when the evaporation rate is …

Fallow Replacement Crop (Cover Crops, Annual Forages, And Short-Season Grain Crops) Effects On Wheat And Grain Sorghum Yields, J. D. Holman, T. Roberts, S. Maxwell

Kansas Agricultural Experiment Station Research Reports

Producers are interested in growing cover crops and reducing fallow. Growing a crop during the fallow period would increase profitability if crop benefits exceeded expenses. Benefits of growing a cover crop were shown in high rainfall areas, but limited information is available on growing cover crops in place of fallow in the semiarid Great Plains. A study was conducted from 2007–2017 that evaluated cover crops, annual forages, and short season grain crops grown in place of fallow. In the first experiment (2007-2012), the rotation was no-tillage wheat-fallow. The second experiment (2012-2017) rotation was no-tillage wheat-grain sorghum-fallow. This report presents results …

Using Precision Agriculture Field Data To Evaluate Combine Harvesting Efficiency, Justin H. Carroll, Don Johnson, Jeff Miller, Kristofor Brye

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Soybeans must be harvested during a limited time period using expensive combines and associated equipment. Maximizing combine field efficiency, the ratio of the actual harvesting capacity to theoretical harvesting capacity, is an important objective of machinery managers. Spatial and temporal yield data from a 2012 CaseIH 8120 Axial-Flow combine equipped with a 9 meter MacDon D-65 Draper header and the Case-IH Advanced Farming System (AFS) yield monitoring system were used to examine field efficiency when harvesting soybean in three Arkansas Delta irrigated soybean fields during the 2015 season. Time efficiencies (TE) in the three fields ranged from 72.9% to 85.8% …

Biotechnology And The Law: A Consideration Of Intellectual Property Rights And Related Social Issues, Michael D. Mehta

The University of New Hampshire Law Review

[Excerpt] “Recent advances in biotechnology are expected by many to improve crop yield, reduce reliance on agricultural inputs like pesticides and herbicides, alleviate world hunger, improve the safety and effectiveness of pharmaceuticals, assist in the discovery of genes that trigger diseases like cancer, and make more efficient our legal institutions through DNA testing. Clearly, innovations in biotechnology are a powerful force for social change, and they pose unique challenges and opportunities for legal scholars and institutions. This section of the Pierce Law Review focuses on the interface between law and technology by examining how innovations in biotechnology accelerate debates about …

Pulses : Profitable New Crops For The Wheatbelt, Kadambot Siddique, Stephen Loss, Ian Pritchard

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

Narrow-leafed lupins have beeb produced on sandy acid soils throughout the wheatbelt for more than two decades. However, the wheatbelt contains large areas ofsoilsnot suited to narrow-leafed lupins. For several years reasearchers have been examining alternatives to narrow-leafed lupins for these soils.

Kadambot Siddique, Stephen Loss and Ian Prichard look at production of these new grain legumes, known as pulses.

Results Of Stubble Research In Western Australia, Michael Perry, Ron Jarvis, Mel Mason, David Tennant

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

Few farmers would question the desirability of retaining stubbles, both for control of erosion by wind and water, and to return organic matter to the soil. While the present debate is focused on the short term management of stubbles, longer term effects also need to be considered.

The Department of Agriculture has several long-running trials intended to measure long term effects.

Opportunity Knocks : Sowing Wheat Early In The North-Eastern Wheatbelt, Nicole Kerr, Doug Abrecht

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

Farmers consider many factors in deciding whether to start sowing wheat, but the most important are the amount of rain and time of year. In this study we assessed the chances of farmers in the north-eastern wheatbelt (less than 325 mm rainfall) receiving enough rain to sow wheat early. In low rainfall areas such as this, where an early finish to the season is likely, it is especially important that farmers take advantage of all early sowing opportunities. The potential benefits of sowing wheat early generally outweigh the associated risks, particularly in lower rainfall areas. However, early sowing depends on …

Wider Spaced Rows For Lupins, Ron Jarvis

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

In this farm scale trial at Wongan Hills, a lined combine was used to seed lupins into rows spaced 380 mm apart in wheat stubble.

Narrow-Winged Seeder Points Reduce Water Erosion And Maintain Crop Yields, Kevin Bligh

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

Sowing crops without loosening the topsoil by tillage reduces water erosion. It can increase infiltration of rainfall into loamy soils, thereby reducing runoff and increasing potential crop yields. Crop yields were maintained after I1 seasons of seeding an Avon Valley loam near Beverley with minimum and no-tillage seeding operations. Infiltration increased significantly from 80 per cent of the 1983 growing-season rainfall under the traditional three tillage operations, to 87per cent under a single tillage operation using a combine seed drill. Infiltration increased further to 96 per cent under a no-tillage system using a triple^lisc drill. At Gnowangerup, 80 per cent …

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

IN four field experiments and two paddock strip trials since 1960, molybdenum applied to wheat and oats grown on scrubplain soils in the eastern wheatbelt increased yields by up to 3 i bushels of wheat and 5^ bushels of oats per acre.

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

A WELL-KNOWN South-West apple orchard with an impressive cropping record is owned by W. F. & E. M. Dilley and Sons, of Upper Capel, near Donnybrook.

Trees in this orchard have been producing consistently heavy crops for many years and, furthermore, yields have increased steadily over a 10-year period.

Delayed Foliation In Apple Trees, J E L Cripps

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

DELAYED foliation refers to the late leafing out and production of small leaves by fruit trees.

However, the weak and protracted blossoming which precedes the appearance of the leaves has more serious consequences for it may lead to a reduced set of fruit.

Farming Without Fallow, H M. Fisher

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

UNDER the more intensive cropping rotations common in the early development of the cereal areas of Western Australia bare fallowing was a basic technique in cereal production.

By ploughing the land in July or August and keeping it bare of vegetation for nine or ten months, either by grazing or cultivation, a substantial beneficial effect on the subsequent crop could be expected.

The Use Of Nitrogenous Fertilisers For Cereal Grain Production In Western Australia, William John Toms, G. H. Burvill

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

NITROGENOUS fertilisers have so far been little used in Western Australia for wheat, oats and barley grown for grain.

However, profitable results can follow their use under some conditions. Farmers who have seen field experiments are now interested in the use of nitrogenous fertilisers.Further interest will be stimulated by recent reductions in price.

This article answers common questions asked by farmers about nitrogenous fertilisers for cereals. It is based on over 100 experiments conducted by the Department of Agriculture during the past 30 years.
