the percentage of fat in liver wet and dry matter, liver moist and dry matter and their relationship were investigated based on species, sex and age of 384 slaughtered animals including 114 cows, 100 buffaloes, 147 sheep and 23 goats from 2008 to 2010 in urmia, iran. mean percentage of fat in liver wet and dry matter, and liver dry matter in cows were 3.6%, 1.1%, 29.7%, buffaloes were 5.3%, 1.5...
To investigate a model to simulate wheat dry matter accumulation, three wheat cultivars with different tillering abilities were grown at three densities each in a field experiment. Five simulation models with high correlation coefficients for relative dry matter accumulation were established by the method of normalized. Among these models, the Richards equation was the best in fitting and forec...
a field study was conducted to evaluate the agronomic response of eight isolines of cv. clark on a clay loam soil (at karaj-iran, 35048´) to four plant population densities of 11.3, 18.5, 68.5, and 103.4 plants per square metre. significant yield increase was obtained as a result of higher plant density. differences among the cv. clark isolines were significant (p
The rise in atmospheric CO(2) concentration coupled with its direct, often positive, effect on the growth of plants raises the question of the response of invasive plants to elevated atmospheric CO(2) levels. Response of two invasive weeds [purple nutsedge (Cyperus rotundus L.) and yellow nutsedge (Cyperus esculentus L.)] to CO(2) enrichment was tested. Plants were exposed to ambient (375 micro...
An, L.V., 2004. Sweet potato leaves for growing pigs: Biomass yield, digestion and nutritive value. Doctor’s dissertation. ISSN 1401-6249, ISBN 91-576-6750-0 The aim of the present studies was to evaluate the potential of using sweet potato leaves (Ipomoea batatas (L.) Lam) as a protein source in diets for growing pigs. A number of sweet potato varieties were evaluated with respect to the bioma...
kochia is a halophyte plant and is a good source of forage for livestock under saline irrigation. in order to investigate the salinity effect on morphological and forage characteristics of kochia, an experiment was conducted. three saline waters (5.2, 10.5 and 23.1 ds m-1) and three kochia ecotypes (birjand, borujerd and sabzevar) were allocated as main and sub plots, respectively, in a split p...

the critical period of weed competition in lentil (lens culinaris medik.) under kermanshah condition
introduction lentil (lens culinaris medik.) is an important legume in the mediterranean area. high protein content in lentil seed (about 22-28%) makes it as a good food source for developing countries and low-income people. in the west of iran such as kermanhah province, it is the most important pulse in rainfed systems cultivated traditionally in rotation with wheat and barley. lentil is grown...
drought is the main constraint limiting chickpea productivity which makes a considerable difference between the potential and actual yield. in order to evaluate the effect of drought stress on different morpho-physiological characteristics of chickpea, four distinct genotypes were studied in three sampling times (pre-stress, stress and recovery) with three replications. as the results implicate...
this study was conducted to evaluate the effects of inoculation of homo-fermentative lactic acid bacteria(lab) on ensiling characteristics and nutritive value of low dry matter corn silage (ldmcs). corn foragewas harvested at milk stage (22.8 ± 0.9% dm), chopped at theoretical length of cut (tlc) 2.5 cm, and stored in eighteen 3.8 l mini silos for each treatment. the following treatments were u...
