The interactions between earthworms and microorganisms can produce significant quantities of plant growth hormones and humic acids which act as plant regulators. Experiments were designed to evaluate the effects of humic acids extracted from vermicompost and compare them with the action of commercial humic acid in combination with a commercial plant growth hormone, indole acetic acid (IAA) whic...

An experiment was conducted to manage the eggplant (brinjal) shoot and fruit borer Leucinodes orbonalis Guenée (Lepidoptera: Crambidae), the leafhopper Amrasca biguttula biguttula (Ishida) (Hemiptera: Cicadellidae), and the whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) during kharif, the southwest monsoon season (Jul-Oct), in 2010 and 2011 at an experimental farm at the Division ...

The study was conducted to evaluate 23 genotypes of marigold (Tagetes spp.) collected from different and diverse sources correlation studies were performed for various growth yield characters. results shows that the maximum plant height (92.60 cm) is recorded in genotype AMS-15, whereas spread (52.80 cm), flower weight (8.93 g) largest size (7.63 ‘AMS-16’. highest number branches (11.13), flowe...

Ap Applicati tions ons in in Pl Plant t Scien Sciences ces Calendula L. (marigold) is the type genus of the small tribe Calenduleae (Asteraceae). While all other genera of the Calen-duleae are native to southern Africa, Calendula is distributed in the Northern Hemisphere. Calendula species occur mainly in the Mediterranean area, from Morocco and Spain to Iran, southward to the Hoggar Mountains ...

Marigold oil is a product of great industrial interest thanks to its wide range medicinal and wound-healing properties. In this work, supercritical carbon dioxide was used recover marigold essential from the hexane solvent extract flowers, floral “concrete”. This starting material mixed with synthetic paraffinic waxes heighten melting point viscosity, thus, improving processability. Supercritic...

Batch cultures of mouse LS cells were grown in suspension at controlled dissolved oxygen partial pressures (pOt). At low pOt (i-6 mmHg) the growth and respiration rates and the final cell population were all limited. At high pOt (320 mmHg), cell division was inhibited after an initial doubling of the cell number. At intermediate values of pOt, the growth rate was constant but the final cell pop...

Effect of cooking, fermentation, dehulling and the use of utensils on flavonoids (quercitin and pelargonidin) - antioxidants present in pearl millet (Pennisetum typhoideum) rabadi, along with proximate composition and sensory acceptability of the product were studied. Study revealed an increased ash and flavonoids and reduced crude fibre after cooking in all samples, while fermentation enhanced...

Varying proportions of binary mixtures of aqueous extracts of jackfruit wood (JFW) with other natural dyes like manjistha (MJ), red sandalwood (RSW), marigold (MG), sappan wood (SW) and babool (BL) were used by the scientists at Institute of Jute Technology, Kolkata and Department of Chemical Engineering, Jadavpur University, Kolkata, India to dye bleached cotton fabric premordanted with 20% my...
