Salinity effects on seed germination and plant growth of guar
The potential of guar [Cyamopsis tetragonoloba (L.) Taub.] as a feasible crop for saline soils was tested in this study by evaluating seed germination of 42 accessions of guar in sodium chloride (NaCl) solution. The seeds were germinated in 200 mM NaCl or double-distilled water (control). There were significant differences in salt tolerance among the accessions tested. Percentages of seeds ...

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 ...

Evaluation of anaerobic digestate as a substrate for vermicomposting
Vermicomposting is an established process to convert organic wastes into vermicastings suitable for plant growth. This research investigated the vermicomposting of anaerobic digestate with four different ratios of sawdust as a bulking material, for 75 days. The optimum proportion of anaerobic digestate to sawdust was identified as 70:30 based on worm growth and reproduction. Vermicomposting ...

Application of soil sensor for agriculture
Background: A moisture sensor that measures the current moisture content of the soil. Sensors into irrigation sensors help to help to facilitate more efficient distribution of water supplies. According to technical classification, soil sensors are divided into the following categories: Ground – installed below the ground to monitor the root zone; Aerial – Using drones to detect data, ...

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 ...

How seed-placed fertilizer may hurt your crops if not applied carefully and attentively
Placing fertilizer within the seed row has been long-standing practice for many farmers across the prairies. Having those nutrients close to the seed makes it easily accessible by the plant, and can help the crop out of the ground and into the sun. Potash fertilizers and other nutrients, such as phosphate, are immobile fertilizers, meaning they don’t travel more than a half-inch through ...

Priming of prosopis cineraria (L.) druce and acacia tortilis (forssk) seeds with fulvic acid extracted from compost to improve germination and seedlin
Composting of waste plant materials and its use in agriculture and landscape sites is an environmental friendly way of reducing waste material and conserving the environment. In this perspectives a survey has been performed at the Dubai based International Center for Biosaline Agriculture to compost the plants based waste material (lawn cuttings-grass) to compost. The material was inoculated with ...

Revolutionizing Agriculture with Intelligent Soil Sensors
Unlocking Data-Driven Insights for Sustainable and Efficient Farming For centuries, agriculture has relied on tradition and intuition, with farmers often relying on their experience and gut feeling to make decisions about their land. However, the 21st century has ushered in a new era in agriculture, one driven by data and innovation. At the forefront of this revolution are intelligent soil ...

What is the right light intensity and illumination length?
Photoperiodism The photoperiod, this is used as a signal for the plant to flower. Many flowering plants (angiosperms) use a photoreceptor protein, such as phytochromeor cryptochrome, to sense seasonal changes in night length, The Phytochrome conversion (Pfr to Pr) allows the plant to sense when it is night or day. Phytochrome Conversion The biologically-inactive form of ...

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 ...

Can chemical treatments to displace radioisotopes influence soil fertility? A laboratory trial
Soils contaminated with radionuclide pose a long–term radiation hazard to human health through exposure via the food chain and other pathways. Remediation of contaminated soils has become increasingly important. The feasibility to move radionuclides from superficial soil layers to a deeper level using an acid leaching solution was already illustrated previously. As this chemical treatment may ...

RMDF Case Study - Compost Mulch a Plum Choice
ReMaDe Kent and Medway is managing a series of WRAP (the Waste & Resources Action Programme) funded trials on top fruit and other horticultural crops in Kent, the ‘Garden of England’, in order to develop the market for compost as a soil improver, and in this trial, as a mulch for young fruit trees. Twelve farms are taking part in the trials growing a wide range of crops, including ...

Nano silicon dioxide mitigates the adverse effects of salt stress on Cucurbita pepo L
Nanotechnology, an emerging science, has advanced research in almost all fields of technology. The aim of the present study was to evaluate the role of nano silicon dioxide (nSiO) in plant resistance to salt stress through improving the antioxidant system of squash (Cucurbita pepo L. cv. White Bush Marrow). We found that seeds treated with NaCl showed reduced germination percentage, vigor ...

PROPAGATION OF CUTTINGS USING EH-POWERGROUND ELECTRIC HEATING MATS
PROPAGATION OF CUTTINGS USING EH-POWERGROUND ELECTRIC HEATING MATS Electric heating mats are used to increase the rooting and germination rate of cuttings. They are manufactured specifically for this purpose and made in sizes to suit new or existing growing beds. The purpose of using heat specifically in the root zone of cuttings is to induce dormancy in the upper vegetative part and to ...

How LED and HPS Lighting affects air and leaf temperature
How LED and HPS Lighting can affect air and leaf temperature: The Effects of Convective Heat vs. Radiant Heat As growers are educating themselves more on different lighting technologies, we have been faced with questions many times over about what effects different light sources have on temperature and crop production; what is the difference between Convection Heat and Radiant Heat? Anyone ...

A Saline Duper Wheat that Tolerates Higher Salt Concentrations!
In the past few decades, agricultural land has been largely lost, and increased salinity in soils around the world has received much attention. Nowadays, nearly 8% of the world's arable land can no longer be used for crop cultivation due to salt pollution, and more than half of the world's countries are affected. Wheat is the second largest grain grown after corn and grows more on Earth than any ...

Controlling Barnyardgrass with Corn Hybrid Selection
Barnyardgrass is a summer annual grass weed with a global impact on corn production. Yield losses due to barnyardgrass competition have been estimated up to 45% or more for crops such as cotton and corn. Besides corn, it can also be a serious weed pest in rice, soybean, sugarbeet, cotton, and corn. Integrated weed management techniques can be used for control of barnyardgrass in corn. High ...

Coated seeds may enable agriculture on marginal lands
A specialized silk covering could protect seeds from salinity while also providing fertilizer-generating microbes Providing seeds with a protective coating that also supplies essential nutrients to the germinating plant could make it possible to grow crops in otherwise unproductive soils, according to new research at MIT. A team of engineers has coated seeds with silk that has been treated ...
