Cotton Planting date: yield, seedling survival, and plant growth
New cultivars, changes in technology and production practices, and climate change may have altered the optimal planting time for cotton (Gossypium hirsutum L.) in the midsouthern United States. A field experiment was conducted from 2002 through 2005 on Gigger silt loam to define planting date (PD) effects on selected cotton cultivars. Six cultivars in 2002 (Deltapine DP555BR and Delta Pearl, ...

Treatment of urea manufacturing facility effluent by Hopea odorata and Khaya ivorensis
Phytoremediation is an environmentally friendly and sustainable alternative for treatment of nitrogen-enriched wastewaters. In this study, Ta-khian (Hopea odorata) and Lagos mahogany (Khaya ivorensis), two tropical timber plants, were investigated for their performances in treatment of urea manufacturing factory effluent with high nitrogen (N) content. Plant seedlings received four ...

Anthocyanin production by over-expression of grape transcription factor gene VlmybA2 in transgenic tobacco and Arabidopsis
An myb-related transcription factor gene of the anthocyanin biosynthetic pathway, VlmybA2, from the Kyoho grape (Vitis labruscana) was introduced into tobacco and Arabidopsis under the control of the cauliflower mosaic virus 35S promoter. The 35S:VlmybA2-induced anthocyanin production was prominent in transformed tobacco calli, and the regenerated tobacco plants were completely purple. Except for ...

Mixture toxicity of copper, cadmium and zinc to barley seedlings is not explained by antioxidant and oxidative stress biomarkers
Metal mixture toxicity analysis to plants is complicated by mutual interactions. Here, mixture effects of zinc (Zn), cadmium (Cd) and copper (Cu) on barley (Hordeum vulgare L.) root elongation were analysed using oxidative stress parameters. The hypothesis was that toxic mixture effects on plant growth are better explained by biochemical parameters than by exposure information, because the ...

Urban Crop Solutions makes indoor farming technology for Mars biosphere
Will the first people to bake and eat bread on Mars do it due to a Belgian breakthrough? This is the challenge facing the SpaceBakery project, a unique consortium composed of seven Belgian organisations using technology provided by Urban Crop Solutions. However, before they use their research to help feed the first people on the red planet later this century, the project aims to have a clear ...

Evaluation of air pollution phytotoxicity downwind of a phosphate fertilizer factory in India
The effects of air pollution on plants downwind of a fertilizer factory at Udaipur, India, were studied using three woody perennials. Seedlings of these species including a shrub (Carissa carandas L.), a leguminous avenue tree (Cassia fistula L.) and a fruit tree (Psidium guajava L.) were grown in earthen pots at different study sites receiving varying levels of air pollution input. Changes in ...

Germination and early plant development of ten plant species exposed to TiO2 and CeO2 nanoparticles
Ten agronomic plant species were exposed to different concentrations of nano titanium dioxide (nTiO2) or nano cerium oxide (nCeO2) (0, 250 µg/mL, 500 µg/mL and 1000 µg/mL) to examine potential effects on germination and early seedling development. We modified a standard test protocol developed for soluble chemicals (OPPTS 850.4200) to determine if such an approach might be useful for screening ...

Inhibition of seed germination and seedling growth of Triticum aestivum L. by industrial wastewaters
The present study was undertaken to determine the effect of different concentrations of wastewaters treated with Pseudomonas putida on various growth indices of durum wheat (Triticum aestivum L.) seeds. Significant decreases in terms of root and leaf growth were observed. The phytotoxicity of textile wastewater was more pronounced on initiation times, germination percentages, root and leaf ...

Compost maturity as expressed by phytotoxicity and Volatile organic acids
VOA in Composts Maturity is a qualitative trait of compost that may be expressed in a number of ways and is generally held to be relevant to plant performance. Volatile organic acids (VOA) have been cited to be responsible for phytotoxicity (plant growth suppression) when immature compost is used for growing plants (Manios et al., 1989). However, the production of VOA in compost has not been ...

Field trial carried out in the ebro valley, Spain case study
Rice farmers in Spain experience two major problems with their rice crops: After the flooding and fertilisation of the rice fields algal growth rapidly develops and covers the surface of the water in the paddy. This greatly reduces the availability of sunlight received by the seedlings until they have grown above the water level. This results in early stage plant loss which can be severe. The ...

What raw materials can be used to produce organic fertilizer
Organic fertilizer is a kind of organic material fermented by microorganisms, such as plant residues, animal manure, organic by-products of processing industry, which can be applied to the soil to provide plant nutrition. Organic fertilizer can provide comprehensive, stable and long-term nutrient elements for plant growth, improve soil structure, improve soil buffering performance, water and ...

Detecting salinity stress in crops
Salinity inhibits growth and development in crops. Due to the extent of damage salinity causes to agriculture, it is identified as a major threat to food production. Therefore, practices to deal with the effects of salinity on crops are receiving a lot of attention. To be able to provide proper recommendations that are also sustainable, it is first necessary to find out how salinity affects ...

Types and maintenance of soil salinity sensors
Background: When people think of salt in relation to crops, the impression is that salt is bad for plant growth. However, it must be remembered that whenever we apply fertilizer, we are adding salt to the soil. So, when measuring soil salt, it can be a case of too much or too little. If the salinity is too high, the roots cannot absorb water. If the salinity is too low, the plants may lack ...

Managing fertilizer’s salt effect in drought
During drought or dry conditions, salinity and pH levels can change quickly in the soil. While the forecast shouldn’t entirely dictate how you manage your farm, understanding and performing the best farming practices when adding seed-placed nutrients can help save your yields when the rain fails to ...

Overexpression of Glutathione reductase in cotton does not alter emergence rates under temperature stress
Cotton (Gossypium hirsutum L.) seedlings are considered to be sensitive to temperature stress. The exposure of plants to high and low temperatures can result in the production of reactive oxygen species that contribute to diminished plant performance. Plants have mechanisms that metabolize oxidants into less harmful chemicals, and enhancement of antioxidant metabolism has been shown to be ...

Putative Seedling Ferulate Ester (sfe) maize mutant: morphology, biomass yield, and stover cell wall composition and rumen degradability
Ferulate cross-linking of lignin to arabinoxylan contributes to poor cell wall degradability of grass forages. We hypothesized that reduced ferulate ester deposition will result in formation of fewer ferulate cross links and improved degradability. Objectives were to determine if the putative seedling ferulate ester (sfe) maize (Zea mays L.) mutant, selected for reduced ferulate esters in ...

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, ...

cheap 50 72 128cell trays wholesale supplier
Due to the need for higher temperature, it is necessary to sprinkle some warm water on the leaves regularly. Plants placed in a dry environment can put a layer of wet small gravel in the flower pot to promote the growth of plants. Seedlings are planted from March to April in spring, or preferably from September to October in winter. Sowing before the frost season. In winter, please manage ...
