Availability of iodide and iodate to spinach (Spinacia oleracea L.) in relation to total iodine in soil solution
Abstract A greenhouse pot experiment was carried out to investigate the availability of iodide and iodate to soil-grown spinach (Spinacia oleracea L.) in relation to total iodine concentration in soil solution. Four iodine concentrations (0, 0.5, 1, 2 mg kg−1) for iodide (I−) and iodate (IO3−) were used. Results showed that the biomass productions of spinach were not ...

Evolution of quality indices of fresh bunched spinach stored using low density polyethylene and polypropylene bags
Packaging technology constitutes an available method for reducing postharvest deteriorative processes on fresh products. The purpose of this work was to evaluate leaf water status, weight loss and colour retention of bunched spinach leaves packaged in low density polyethylene (LDPE) and polypropylene (OPP) bags, stored at 2°C for 25 days. Water status was determined through relative water content ...

Biochar impact on physiological and biochemical attributes of Spinach (Spinacia oleracea L.) in nickel contaminated soil
Disastrous effect of nickel on spinach was discussed by number of authors but the effect of amendments like biochar with nickel on Spinacea oleraceaL. is not still discussed by any author of the world because biochar was used as soil amendments which play a vital role in reducing mobilization and uptake of nickel by spinach plants. As nickel contaminated plants are very harmful for the ...

Modelling water requirements of greenhouse spinach for irrigation management purposes
Estimating water requirements of plants cultivated in greenhouse environments is crucial, both for the design of greenhouse irrigation systems and the improvement of irrigation scheduling. Spinach is one of the main vegetables sold as ‘ready-to-eat’ bagged produce; it is very sensitive to water stress and thus requires accurate irrigation. In this work, a water balance model simulating the ...

Comparing pesticide residues in Amish and commercially grown strawberries and spinach using QuEChERS, Various dSPE Sorbents, and GC-TOFMS
Abstract QuEChERS extraction, dSPE cleanup, and GC-TOFMS analysis were used to assess pesticide levels in strawberries and spinach from both commercial and Amish growers. Various dSPE cleanup products were compared to determine which were most effective. Good recoveries were obtained for most pesticides; however, low recoveries were observed for some base-sensitive or planar compounds. Incurred ...

Conversion of solid organic waste into compost using Trichoderma spp. and its application on some selected vegetables
This study was conducted to evaluate the potentiality of Trichoderma species as a bio-conversion agent for composting of solid organic waste and examine the effects of produced composts on the growth of two types of vegetables. The experiments were conducted both in vitro and in vivo processes. In vitro conversion of solid organic waste, the highest height and weight losses were found 42.64 ...

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 ...

Aiming to optimize irrigation levels
With irrigation being used in many spheres of life and food production methods getting diversified, it is not surprising that research on this topic is getting more specialized. Procedures for analysis, which were restricted earlier to big institutions, need to be widely available so that their reach is extended and science will benefit from more in-depth studies. An increasing number of ...

The Importance of Leaf Area Index (LAI) in Environmental and Crop Research
Leaf Area Index (LAI), which is used as a measure in hundreds of studies on forests, crops, climate and the environment, is calculated as half the area of all leaves per unit area of ground. It is measured as the leaf area (m2 ) per ground area (m–2) and is unit-less. So, a plant with a LAI of 2 has an amount of leaves that can cover a given area two times. LAI is calculated for a plant or ...
