The aim of the present study was to evaluate the influence of roasted soybean and sunflower meal on the consumption and growth performance of lambs from the Blackhead Pleven Breed. The results indicated that the addition of roasted soybean caused the lambs to grow significantly faster than those fed sunflower meal (P

Following domestication, crop lineages typically undergo diversification either to adapt to disparate habitats or to fill novel agricultural roles. This process has produced the numerous varieties found in modern-day crop germplasm collections. Here, we mapped quantitative trait loci (QTLs) underlying unique traits in the Hopi sunflower, a primitive, Native American domesticate. These traits in...

abstract recently weed scientist are more interested in weed management by allelopathy . the main objective of the study was to evaluate allelopathic potential of sunflower on redroot pigweed and common lambsquarter. this study was conducted in two series of laboratory and greenhouse experiments. under laboratory conditions, leaf, stem and root aqueous extracts of sunflower at 0%, 2.5%, 5%, 7.5...

Four recently duplicated flowering genes in sunflower have met diverse fates, including acquisition of a new regulatory function, providing intriguing insights into duplicate gene evolution as well as sunflower domestication.

this research was conducted to determine the best temperature for storing different melon cultivars (ghasry, khaghany, tashkandy) and the best concentration and treatment length for immersion in an emulsion of sunflower oil and sodium bicarbonate. after harvest, precooling and sorting, the melons were treated with an emulsion of sunflower oil (3%, 5%) and sodium 2% sodium bicarbonate for 5 or 1...

Two experiments were conducted to determine the effects of sunflower seed supplements with varying fatty acid profiles on performance, reproduction, intake, and digestion in beef cattle. In Exp. 1, 127 multiparous spring-calving beef cows with free-choice access to bermudagrass hay were individually fed 1 of 3 supplements for an average of 83 d during mid to late gestation. Supplements (DM basi...

Esters of plant oils are preferred to parent oils if used as fuels in diesel engines because esterification reduces the viscosity of plant oils and makes it comparable to that of diesel. The present work mainly deals with the effect of storage time on the quality of plant oils and their esters with respect to mainly FFA content, viscosity and change in weight. The study was carried out for a pe...

Sunflower stalks were analysed for chemical compositions: pentosan 15.84%, holocellulose 70.69%, alphacellulose 45.74%, glucose 27.10% and xylose 7.69% based on dry weight of 100-g raw material. The most optimum condition for steam explosion pretreatment was as follows. Sunflower stalks were cut into small pieces and soaked in 0.02 M H2SO4 for overnight. After that, they were steam exploded at ...

There exist some fuzziness and uncertainty in the process of ecological construction. The aim of this paper is to develop a direct and an effective simplified method for obtaining the cost-sharing scheme when some interested parties form a cooperative coalition to improve the ecological environment of Min River together. Firstly, we propose the solution concept of the least square prenucleolus ...

biofuels are the main substitute to fossil fuels. these fuels are less polluting in compari-son to fossil fuels and can be produced from agricultural material residues for use in die-sel engines. in this research work bioethanol was produced from potato waste. it was de-hydrated in a vapor phase using 3a zeolite and was used in combination with sunflower methyl ester oil and diesel fuel blendin...
