Characterization of corn Nitrogen status with a greenness index under different availability of Sulfur
Several methodologies measure leaf greenness intensity and relate it to crop N status. There is no evidence, however, of the utility of this variable to detect N deficiencies in corn (Zea mays L.) under S deficiency. The objective of this work was to evaluate the potential of two indexes based on leaf greenness intensity to detect N deficiencies in corn under different levels of S. Two ...

Toxic metals status in human blood and breast milk samples in an integrated steel plant environment in Central India
Owing to its unique nutritional and immunological characteristics, human milk is the most important food source for infants. Breast milk can, however, also be a pathway of maternal excretion of toxic elements. Selected toxic elements (As, Pb, Mn,a Hg and Cd) were determined in human breast milk and blood samples obtained from 120 subjects related to an integrated steel plant environment located ...

Summer–fall seeding dates for six cool-season grasses in the midwest united states
The effect of late summer (fall) planting date for cool-season grasses in the upper Midwest is not well understood. Objectives of this research were to determine optimum planting dates of late-summer/fall seedings in different environments for several cool-season grass species and to gain information on tiller density and tillers plant–1 relative to dry matter yield. Late-summer/fall seedings of ...

Retail survey of brazilian milk and minas frescal cheese and a contaminated dairy plant to establish prevalence, relatedness, and sources of listeria monocytogenes isolates
A study was designed to recover Listeria monocytogenes from pasteurized milk and Minas frescal cheese (MFC) sampled at retail establishments (REs) and to identify the contamination source(s) of these products in the corresponding dairy processing plant. Fifty milk samples (9 brands) and 55 MFC samples (10 brands) were tested from REs located in Juiz de Fora, Minas Gerais, Brazil. All milk samples ...

Sand abrasion injury and biomass partitioning in cotton seedlings
Wind blown soil particle abrasion negatively impacts millions of hectares of crops annually. The goal of this study was to examine the effects of wind and wind blown sand abrasion damage on cotton (Gossypium hirsutum L.) seedling biomass partitioning to leaves, stems, and roots. Seedlings of three cotton cultivars were exposed to no wind (untreated controls) or sand abrasive flux densities of 0, ...

Growth and phosphorus uptake of three riparian grass species
Riparian buffers can significantly reduce sediment-bound P entering surface water, but control of dissolved P inputs is more challenging. Because plant roots remove P from soil solution, it follows that plant uptake can reduce dissolved P losses. We evaluated P uptake of smooth bromegrass (Bromus inermis Leyss.), reed canarygrass (Phalaris arundinacea L.), and switchgrass (Panicum virgatum L.) ...

Study on veterinary and human antibiotics in raw and treated water from a French basin
The aims of this work are to evaluate the presence of antibiotics in surface waters in a French water basin, where the presence of livestock is relatively important, and to understand the behaviour of antibiotics in drinking water treatment plants (DWTPs). Two sampling sites were chosen because of their livestock density and the presence of DWTPs in areas where urban activities are different. ...

Capabilities of four novel warm-season legumes in the southern great plains: Grain production and quality
Grain legumes could serve as a low cost nitrogen (N) and energy source for animal production in the southern Great Plains (SGP). This study evaluated the yield and nutritive value of grains of tropical annual legumes novel to the SGP. Included were cultivars of pigeon pea [Cajanus cajan (L.) Millsp.] (cv. GA-2), guar [Cyamopsis tetragonoloba (L.) Taub.] (cv. Kinman), cowpea [Vigna unguiculata ...

How crop registration boosts quality, quantity & consistency
Crop registration - an essential piece of the puzzle No matter how well controlled a growing environment is, environmental conditions are bound to vary from time to time. This can be due to the weather conditions in your natural climate, interactions between different plant species or even changes in your operational practices. It’s essential to gain knowledge and understanding of all of ...

Development of Waste Sawdust as a plant protection material for horticulture and agriculture
Untitled Document Lignin is one of the major wastes of modern society, in the form of wood waste such as sawdust. In nature, lignin is slowly digested to soil humus. This project is to ascertain whether sawdust could be digested into a plant protection material. The value of this would be that it would control some pests and diseases without being a pesticide nor fertilizer. ...

How to Use Labels in Your Growing Cannabis Business
With medicinal as well as recreational cannabis being legalized across North America in recent years, the industry has seen tremendous growth. However, while this has led to impressive profits for a growing cannabis business, including producers and distributors, it has also brought with it a host of new regulations and standards. This includes strict regulations on the identification of all ...

Study of agglomeration in 3.5 MW AFBC using rice husk particles
The combustion of rice husk in fluidised bed combustors seems to be an attractive possibility for power generation in the future, keeping in view the waste disposal problems and the reduction of greenhouse gases. In commercial installations, the occurrence of agglomeration is still one of the main reasons for unscheduled outrages. In this paper, a review of agglomeration mechanism and its ...

Behavioural and chemical ecology underlying the success of turnip rape (Brassica rapa) trap crops in protecting oilseed rape (Brassica napus) from the pollen beetle (Meligethes aeneus)
There is increasing interest in the use of trap crops as components of integrated pest management (IPM) strategies. Understanding the mechanisms underlying host plant preferences of herbivorous pests can lead to improved effectiveness and reliability of the trap crop. We investigated the behavioural and chemical ecology underlying the success of turnip rape, Brassica rapa, trap crops in ...

Distribution of arsenic and other minerals in rice plants affected by natural straighthead
Because of the inconsistency and unpredictability of naturally occurring straighthead, arsenical herbicides are sometimes used to induce straighthead-like symptoms to study this sterility disorder. In 2005, an outbreak of naturally occurring (nonchemically induced) straighthead in rice (Oryza sativa L.) study fields in Stuttgart, AR provided an opportunity to examine the role of minerals in this ...

Spectral Reflectance Properties of Winter Cover Crops in the Southeastern Coastal Plain
Conservation tillage is a commonly adopted best management practice for reducing runoff and erosion, and increasing infiltration. Yet current methodologies in place to monitor conservation tillage adoption are largely inappropriate for regional or national assessments. A major goal of this study was to evaluate the spectral response properties of four alternative winter cover crops using remotely ...

Improved wheat grains storage
Improved wheat grains storage management SmartScan25 was installed at the Israeli large flour mill to improve wheat grains storage management, save costs and reduce material losses. Israeli Mills Ltd, located in the city of Tel Aviv, is one of the leading local flour providers. The mill produces various types of wheat products such as: bran, white flour, semolina and more, for local use. The ...

Improving alfalfa irrigation in The west
Alfalfa grown for forage is a major crop in many areas of the western United States. In the arid and semi–arid west, irrigation is required to obtain economic alfalfa yields. Because alfalfa is a perennial crop with a potentially long growing season, it can use a substantial amount of water. Alfalfa production in Imperial County, CA, has been valued at more than $170 million dollars for ...

Impact of Agri-environment measures
The application of agri-environment contracts concerning 1 farmer in every 7 and delivering environmental services over 20% of European farmland, marks a very significant step towards sustainability. The target set in the 5th Environmental Action Programme of 15% coverage by 2000 has thus already been exceeded. The requirement on Member States to apply the regulation throughout their territories ...
