چکیده
salinity of soil and irrigation water creates major problems for forage production. this study was aimed to evaluate the quality and quantity of forage production in intercropping of kochia (kochia scoparia l.) with blue panic grass (panicum antidotale retz.) under irrigation with saline water (4.9 ds.m-1). the study was performed based on randomized complete block design with three replications during growing season 2010-2011 at salinity research field, of ferdowsi university of mashhad. treatments were five different levels including 100, 75, 50, 25 and 0 percentage of relative composition of the two species. treatment of 50% blue panic grass and 50% kochia with an average of 1408 g.m-2 produced the highest dry matter yield followed by 25% blue panic grass + 75% kochia and 75% blue panic grass + 25% kochia produced 1317 and 993 g.m-2, respectively. due to lower growth rate of blue panic grass in the first year, a large proportion of dry matter in the mixture was associated with kochia and land equivalent ratio was less than one in all intercropping treatments. in the first and the second clippings, there was no significant difference between intercropping treatments in terms of crude protein, ash, ndf and adf.

This study underscored an underexploited crop, blue panic grass as a potential crop for hot and saline regions. It investigated feed value of the crop at two growth stages, before flowering (BF) and after flowering (AF), and under different levels of humic acid application (HA, at 0, 15, 30, 45, 60, 75, and 90 kg ha). Significant (P < 0.05) effects of different growth stages, HA while non-signi...
متن کاملNutritional and toxicological evaluations of kochia hay (Kochia scoparia) fed to lambs.
Kochia foliage that had tested positive to Dragendorff's reagent (presumptive alkaloids) and had elicited chronic toxicosis when fed to rats was fed to sheep to characterize early stages of kochia toxicosis and evaluate treatments that might improve tolerance. Twelve fine-wool lambs (46 +/- 9 kg BW) were fed chopped kochia hay (35%) mixed with chopped alfalfa hay (65%) for 4 wk. The kochia diet...
متن کاملFitness Outcomes Related to Glyphosate Resistance in Kochia (Kochia scoparia): What Life History Stage to Examine?
A fast-spreading weed, kochia (Kochia scoparia), has developed resistance to the widely-used herbicide, glyphosate. Understanding the relationship between the occurrence of glyphosate resistance caused by multiple EPSPS gene copies and kochia fitness may suggest a more effective way of controlling kochia. A study was conducted to assess fitness cost of glyphosate resistance compared to suscepti...

Kochia hay that had elicited mild toxicosis in sheep and cattle when fed for 21 d was fed to young, growing steers to evaluate the efficacy of metoclopramide for preventing kochia toxicosis. Twelve steers (271 +/- 39 kg) were given ad libitum access to Kochia hay for 38 d. Six steers were dosed orally with 15 mg of metoclopramide/kg of BW three times each week in gelatin capsules, and six steer...
