A Novel Method For Detecting Morphologically Similar Crops And Weeds Based On The Combination Of Contour Masks And Filtered Local Binary Pattern Operators, Vi Nguyen Thanh Le, Selam Ahderom, Beniamin Apopei, Kamal Alameh
Research outputs 2014 to 2021
Background: Weeds are a major cause of low agricultural productivity. Some weeds have morphological features similar to crops, making them difficult to discriminate. Results: We propose a novel method using a combination of filtered features extracted by combined Local Binary Pattern operators and features extracted by plant-leaf contour masks to improve the discrimination rate between broadleaf plants. Opening and closing morphological operators were applied to filter noise in plant images. The images at 4 stages of growth were collected using a testbed system. Mask-based local binary pattern features were combined with filtered features and a coefficient k. The classification of …
Evaluation Of Crop Production And Water Use Efficiency Of Autumn-Sown Annual Forage Crops On The Rainfed Region Of Loess Plateau China, Qingping Zhang, Lihua Tian, Yuanbo Liu, Lindsay W. Bell, Jeremy P. M. Whish, Yuying Shen
Evaluation Of Crop Production And Water Use Efficiency Of Autumn-Sown Annual Forage Crops On The Rainfed Region Of Loess Plateau China, Qingping Zhang, Lihua Tian, Yuanbo Liu, Lindsay W. Bell, Jeremy P. M. Whish, Yuying Shen
IGC Proceedings (1997-2023)
The Loess Plateau is one of the most important rainfed regions in China, but rainfall is the most significant factor limiting crop production. In this region rainfall from July to September accounts for 56% of the annual total, providing enough water resources for the growth of autumn-sown crops. Although increasing forage production with autumn sown crops is considered an important means of balancing crop forage and livestock management, suitable species with high yields and good water use efficiency (WUE) are not well defined.
The relationship between yield and water use efficiency has been shown to vary with plant species and …

Changes In Soil Microbiology Under Conventional And No-Till Production During Crop Rotation, C. J. Hsiao, G. F. Sassenrath, L. Zeglin, G. Hettiarachchi, C. Rice
Kansas Agricultural Experiment Station Research Reports
Soil microbial activity is important for crop production. Soil microbes are involved in nutrient and water cycling within the soil, and interact with crop plants to provide the basic nutrient and water resources needed for crop production. Claypan soils have unique physical characteristics that impact soil biology. This study explored the temporal changes in soil microbiology in a claypan soil under conventional and no-till production during a crop rotation of corn/winter wheat/soybean/fallow commonly planted in southeast Kansas. We found soil microbial activity changed more in the top two inches of soil than in the lower soil layers. Wheat resulted in …

Key Components Of Healthy Soils And Their Role In Crop Production, C. J. Hsiao, Gretchen Sassenrath, Charles Rice, L. Zeglin, G. Hettiarachchi
Kansas Agricultural Experiment Station Research Reports
Soil health is a confusing term that means different things to different people. To a crop producer, healthy soils are critical for good crop growth and yield. Some soil properties include soil texture, such as the relative percentage of sand, silt and clay; the water content; nutrient levels; organic carbon content; the microbial community; and microbial activity. These properties are determinants of soil health. Our research confirmed that changes in soil management affect the composition and activity of soil microorganisms in surface soils. Greater concentrations of microbial biomass and arbuscular mycorrhizal fungus (AMF) in the no-till agricultural system indicated healthier …

Profitable Canola Production In The Great Southern And Lakes District, Paul Carmody, Ashley Herbert
Profitable Canola Production In The Great Southern And Lakes District, Paul Carmody, Ashley Herbert
Bulletins 4000 -
The Canola industry has rapidly grown with a 10 fold increase in area sown in Western Australia over the four years from 1996-99.
The driving force behind this increase in area can be attributed to the successful adoption of weed control technology in Triazine Tolerant Canola.
By knowing the model of the limiting factors, which are usually; weed control, fertiliser practices, blackleg management, variety selection, seeding dates, seeding depths, insect control and swathing, we can make the right decisions and achieve the targeted profit.
To produce yield to potential, all factors need to be optimised, otherwise yields will be decreased …

Bulletins 4000 -
Why grow canola in the South Coast Region? Canola is a member of the Brassicaceae family, which also includes mustard, turnip, wild radish, cauliflower, cabbage and broccoli. It is a winter growing oilseed that can be produced in most arable areas of Australia where winter crops are currently grown. Originally known as rapeseed using the species B. campestris, the species of B. napus have almost completely replaced this earlier species in all the areas where the crop is grown.

Merging Conservation With Production In Remnant Bush, Anne Morgan, Alison Fuss
Merging Conservation With Production In Remnant Bush, Anne Morgan, Alison Fuss
Journal of the Department of Agriculture, Western Australia, Series 4
Exports of cutflowers and foliage from Western Australia are now worth about $17 million a year. A third of this is picked from the bush, either on Crown Land or areas of remnant bush on private property. While the industry's future lies in cultivation, bush picking is likely to remain important for some years. This can provide both extra income for farmers and benefit the environment - as long as care is taken

Over the past 1O years, Western Australia's ornamental plant industry has experienced significant growth in value. The industry has expanded and adopted new technologies, but some enterprises have closed There have also been major changes reflecting the economic climate and conservation pressures.
The ornamental plant industry in this State is valued at more than $70 million annually. It encompasses three areas: nursery production, exotic cutflower production, and native cutllower production. The native cutflower industry is by far the largest growth sector.
