weed's behaviors differ in a multiweed-crop competition system compare to a mono weed-crop competition system. the present investigation was carried out in mashhad, iran, to study the effect of weeds, which emerged naturally in a multi species community along side with melon, on quantitative and qualitative characteristics of the crop during 2007. thirty five plots were selected randomly in a g...
In the area with terminal heat and drought stress such as Gonbad, allocation of produced dry matter to reproductive organs is of great importance. In order to evaluate the effect of different temperature and moisture regimes on dry matter distribution and harvest index ofcanola an experiment wasconducted at Agricultural Research Station of Gonbad during 2005-2007. The experiment was a RCBD arra...
In a pot experiment, the growth (Dry matter) responses of 18 rapeseed varieties to three levels of NaCl salinity induced by 1.2, 6, and 12 dS.m-1 were investigated using a factorial experiment with a randomized complete block design in 3 replications. The results indicated that salinity reduced total dry matter, Na concentration, K/Na ratio, ion selectivity of K versus Na, and leaf water potent...
one very decisive factor in students’ academic destiny is the result they get at final term examinations. because of its importance, both students and teachers are curiously anxious about them. as normally it is the case, these final term tests are prepared hurriedly in short time by teachers which result in students’ dissatisfaction, complaining on how the test was different from their expecta...
AKDAG, F., O. CADIRCI and B. SIRIKEN, 2010. Effect of estrus on milk yield and composition in Jersey cows. Bulg. J. Agric. Sci., 16: 783-787 This study was performed to demonstrate the effect of estrus on milk yield and composition in Jersey. In this study, 15 jersey cows which were at the same estrus period, in the third lactation period and breeding under uniform housing and feeding condition...
crop productivity, water use efficiency (wue), and microbial biomass c and n in rainfed dry area are influenced by tillage, rotation, and crop residue management. field experiments were conducted during 2005-08 to study the effect of tillage, crop rotation, and crop residue retention on oat fodder yield, water use efficiency, and microbial biomass c (mbc) and n (mbn) under semi-arid conditions ...
Nowadays, the root characteristics as one of secondary traits along with grain yield are used to response evaluation of rice genotypes under deficit irrigation. Thus, to evaluate the root traits of 40 irrigated rice genotypes to water limited condition a pot experiment was performed in 2014 at Rice Research Institute (Rasht), Iran. Irrigation treatment was applied in two levels include con...
abstract the current study examined the role of emotional intelligence and motivation on language learning of efl learners in iranian context. the participants of this study were 162 female and 100 male junior high school students. these participants were selected by convenient sampling method. to carry out the study two questionnaires were administered to the participants. first, the adap...
this study was carried out to determine nutritive value and the effect of amaranthus grain on performance and carcass characteristics of broiler chicks. chemical composition of amaranthus grain including dry matter, crude protein, crude fiber, crude ash, and gross energy were 91.04, 17.50, 8.40, 2.70, 5.41, percent and 4515 kcal/kg respectively. metabolizable energy content of amaranthus grain ...
