Effect of pepper and onion as additives on groundnut oil expression
The effect of pepper and onion on the yield of oil expressed from groundnut paste was investigated. The results showed that oil expressed from groundnut with pepper as additive has the highest average yield in comparison with oil obtained using onion as the additive or without additives. Oil yields obtained when pepper was added at low and high levels were 31 ml and 35 ml per 100 g of groundnut, ...

Bio-stimulants Effect on Pepper Plant Performance Case Study
Two bio-stimulants were tested, along with a normal nutrition control treatment, in order to determine the effect on sweet pepper (Capsicum annuum) plant growth, water use efficiency, drought tolerance and resilience. All plants, excluding control plants, were exposed to drought and recovery period, and their physiological response was ...

Biosorption of textile dye reactive blue 221 by capia pepper (Capsicum annuum L.) seeds
Peppers are very important foodstuffs in the world for direct and indirect consumption, so they are extensively used. The seeds of these peppers are waste materials that are disposed of from houses and factories. To evaluate the performance of this biomass in the treatment of wastewaters, a study was conducted to remove a textile dye, reactive blue 221, which is commercially used in textile ...

Water use efficiency and productivity of habanero pepper (
Capsicum chinense Jacq.) based on two transplanting datesHabanero pepper production was assessed with drip irrigation and plastic mulch, based on two transplanting dates. The objectives of the study were: (i) to evaluate the effect of two transplanting dates and the use of plastic mulch on water productivity and habanero pepper fruit yield under drip irrigation conditions; and (ii) to determine the profitability and economic viability of the product ...

Pesticide residue evaluation in major staple food items of Ethiopia using the QuECHERS method: A case study from the Jimma zone
Samples of maize, teff, red pepper and coffee (green bean and coffee bean with pulp) were collected from a local market in Jimma zone, Ethiopia. Samples were analyzed for the occurrence of cypermethrin, permethrin, deltamethrin, chlorpyrifos ethyl, DTT and its metabolites, and endosulfan (α, β). In the analytical procedure, the QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) ...

Studies on the efficacy of physical, chemical and biological aflatoxin B1 detoxification approaches in red chilli powder
Aflatoxin free powdered red pepper (100 g) was spiked with 100 ppb of aflatoxin B1 (AFB1) in methanol and was subjected to various physical (UV irradiation, heating, microwave); chemical (oxidation, bleaching, ammoniation, sulphitation) and biological (enzymatic) treatments. The residual AFB1 was quantified by standard methods to find the efficiency of different treatments in degrading AFB1. ...

Root-knot nematode-resistant alfalfa suppresses subsequent crop damage from the nutsedge-nematode pest complex
Southern root-knot nematode [RKN, Meloidogyne incognita (Kofoid & White) Chitwood], yellow nutsedge (YNS, Cyperus esculentus L.), and purple nutsedge (PNS, C. rotundus L.) occur together as a mutually beneficial pest complex in sandy soils. All crops grown in infested soils are affected due to the wide host range of the nematode, the perennial life cycle of the nutsedges, their interactions, ...

Contamination of the organophosphorus insecticide ethion residues in commercial samples of red-hot chilli spice in Kuwait
This study aims to determine the contamination residue levels of ethion in different forms of red-hot chilli samples using gas chromatography analysis with tandem mass spectrometry detection mode. The results of this study clearly demonstrated that the percentage of ethion residue levels decreased remarkably from 81 to 19% of 156 and 384 red chilli samples analysed during 2004 and 2005, ...

Gingerol: The Chemistry Behind Ginger
Ginger is a popular spice now a major part of Christmas tradition in the form of gingerbread. But what makes ginger flavour so pungent? Chemistry explains. The chemistry of the compounds that make up the ginger we find at supermarkets – also known as garden ginger - are responsible for the strong flavour we associate with the spice. What’s more, the compounds are altered when ginger ...

Birds Check Out of University Library Thanks to StealthNet
The University of Texas at Austin’s Perry-Castañeda Library building is a marvel of mid-century institutional design. The monolithic limestone structure is peppered with ordered rows of recessed windows that allow sweeping views of the campus while blocking direct sunlight, reducing summer cooling costs in the massive building. These window recesses, however, provided perfect little ...

Measurement and modelling of the water requirement of some greenhouse crops with artificial neural networks and genetic algorithm
Crop evapotranspiration is the most important parameter for management of irrigation systems in greenhouses. This study was conducted to determine the evapotranspiration of cucumber, tomato and peppers, using micro–lysimeter during seven months in a greenhouse located in central region of Iran. Reference evapotranspiration estimated using drainage lysimeters and the water balance of soil ...

Irrigation and Nitrogen Best Management Practices Under Drip Irrigated Vegetable Production
Abstract Plastic mulch and drip irrigation are commonly used in high intensity vegetable production regions such as Florida. Drip irrigation can be much more efficient than sprinkler irrigation since only the root zone of the cropped area is irrigated. However, improper irrigation management can lead to wasted water and leaching of soluble chemicals such as nitrate. In this project, several ...

Monitoring of Nitrate Leaching in Sandy Soils: Comparison of Three Methods
Abstract Proper N fertilizer and irrigation management can reduce nitrate leaching while maintaining crop yield, which is critical to enhance the sustainability of vegetable production on soils with poor water and nutrient-holding capacities. This study evaluated different methods to measure nitrate leaching in mulched drip-irrigated zucchini, pepper, and tomato production systems. Fertigation ...

Fertilization and blending alternatives for irrigation with desalinated water
Received for publication April 29, 2008. In arid-zone agriculture where available irrigation water is saline, desalination is becoming an attractive method for increasing yields and reducing negative environmental consequences. However, irrigation with desalinated water can be problematic if essential nutrients, including Ca, Mg, and S, removed during reverse osmosis, are not reintroduced. We ...

AFLATOXINS Toxins in Peanuts, Vegetable Matter and Milk
Aflatoxins occur naturally in peanuts, peanut meal, cottonseed meal, corn, dried chili pepper, etc. However the growth of mold does not always indicate the presence of toxin since the yield of Aflatoxins is dependent on growth conditions such as moisture, temperature, and aeration. The Aflatoxins are characterized as B for blue fluorescence and G for green fluorescence. The numerical subscripts ...

Lighting Strategies for Vine Crop Production
Pepper, tomato and cucumber crops require consistent levels of light for year round production. There are many things to consider before investing in a lighting solution and understanding your growing environment – and the goals you want to achieve – will help in choosing a system that best suits your needs. Having a reliable and efficient lighting system is important not only for ...

Commercial greenhouse water demand sensitivity analysis: single crop case study
Today water distribution utilities are trying to improve operational efficiency through increased demand intelligence from their largest customers. Moving to prognostic operations allows utilities to optimally schedule and scale resources to meet demand more reliably and economically. Commercial greenhouses are large water consumers. In order to produce effective forecasting models for ...

CO2 Foliar Spray Affects on Pepper Plant Growth Case Study
Indoor use of C02 gassing has enhanced plant yields for over 60 years. However, over 50% of the C02 gas is typically lost through ventilation. Current greenhouse C02 gassing levels of up to 1500 PPM are also not ideal for worker health and safety. GRO's safer dissolved C02 foliar spray can be used by indoor and outdoor plant growers with minimal C02 gas lost and greater plant bioavailability ...
