this research aimed at investigating the effect of different levels of nitrogen and planting patterns on dry matter production and growth physiological indices in intercropping maize and sunflower. to do this a split plot experiment carried out based randomized complete block design with three replications in research field of shushtar islamic azad university. the main plot included three level...

background: over recent decades a possible decrease in sperm quality and an increase in the incidence of testicular cancer have been reported in many populations. some recent findings, as cohort studies, showed an increased risk of testicular cancer in men with abnormal semen analysis. case: a 30 years old man referred to our clinic with chief compliant of infertility for 3 years. spermogram re...

Maize oil is high in polyunsaturated fat, which is a heart-healthy fat, and low in saturated fat. Extraction of oils from oilseeds is a key step for their commercialization. The extraction process has a direct effect on the quality and quantity of protein and oils obtained. Various methods like cold pressing, solvent, super-critical fluid and aqueous extractions are in practice for oilseed extr...

on the basis of acreage, production and import amounts, maize is one of the strategic products in iran, regarding defects of marketing system of maize, in this analysis using yearly observations between 1368 to 1385 (18 years) and eviews software, the marketing and econometric model of maize marketing margin was studied. the results show that the most important factor in the maize marketing mar...

Integrated crop–livestock systems that intercrop forage crops with grain are effective for increasing production and improving nutrient cycling soil health. However, the potential root competition when maize (Zea mays L.) sorghum [Sorghum bicolor (L.) Moench] intercropped forages in sandy soils is unknown. The objectives of this study were (a) to evaluate growth characteristics grasses (b) quan...

Orobanche cumama wallr. is the sunflower root parasitic weed with special life stage in which seed germination and parasitism take place soil. In practice, applying microbial agents trapping crop rotation are utilized separately, or just one of them selected to control O. cumana. The development industry severely constrained on farmland, where there high density cumana’s banks. this study, two ...

We prove that a hyperbolic Dulac germ with complex coefficients in its expansion is linearizable on standard quadratic domain and the linearizing coordinate again germ. The proof uses results about normal forms of transseries [19].

Abstract To find out how maize and potato can grow and develop in an intercropping system rather than each grown alone in a sole cropping system the following factorial experiment was performend in the frame-work of a randomized complete block three replications in the experimental farm of the faculty of agriculture, Zanjan University in year 2004. Different potato to maize ratios of (1:0), i...

to compare the quantity and quality of forge production in intercropping systems with maize, pinto bean and pumpkin, an experiment based on randomized complete block design with three replications was conducted at faculty of agricultural science, university of guilan, during 2012 growing season. the treatments consisted of maize, pinto bean and naked pumpkin sole cropping, maize – pinto bean an...
