Cumin (Cuminum cyminum L.) is one of the most important cultivable medicinal plants in Iran and today, it is the second most popular spice in the world after black pepper. It is essential to know the relationships between yield and its components in cumin breeding programs. Therefore, different multivariate statistical analysis was performed on plant characters in cumin to determine th...
in order to study the effects of irrigation levels on growth criteria, yield components and seed yield of four ecotypes of sesame (sesamum indicum l.), a field experiment was conducted as factorial based on a randomized complete block design with three replications at the agricultural research station, ferdowsi university of mashhad, during growing season 2010-2011. three irrigation levels (200...
In order to evaluate the effects of different levels of phosphorus (P) and boron (B) on yield, yield components, seed quality (protein and oil content) and P and B content of rapeseed (Brassica napus L.), a greenhouse experiment (aimed at removal of other environmental factors affecting growth parameters, which are not manageable in the field) was conducted. Treatments consisted of two cultivar...
This research was made during the 2011 and 2012 growing periods in the trial filed of "Research Station for Management of Soil Water and Desertification" according to “Randomized Blocks Design” with 3 replications. Research material was the following chickpea genotype; CA119, CA128, CA149, CA150, CA222, CA250, CA254 and other 2 commercial varieties named as Gökçe and Yaşa. Some agronomical char...
A linear equation of regression was used for establishment of the influence of quantitative characteristics on the grain productivity in forage pea and for development of a model for breeding work. The model for pea plant with high productivity was characterized by average height of 60–70 cm, 8–10 formed pods, 30–40 seeds per plant and 160–260 g in regard to 1000-seed weight. The obtained resul...
In addition to seed quantity, study of seed quality of crop in conditions of competition could be profitable for seed procurement from field. For this purpose, produced seeds of four wheat cultivars (Sayson, Alvand, Chamran and Sepahan) in interference with deferent densities of feral rye (0, 20, 40, 60 and 80 plants m-2) were harvested. In laboratory, of each field unit, 50 number of wheat see...
the higher levels of essential elements in soil may be caused in optimum yields and crop quality. so it seems to be necessary to examine different levels of nutrients like fe and zn on plants and their productivity. to evaluate effects of iron and zinc application on yield and yield components of pimpinella anisum an experiment was conducted at the research farm of urmia university in 2009. tre...
An experiment was conducted to study the effects of plant density and cultivars on seed yield and yield components of corn (Zea mays L.) under the climatic conditions of Khorramabad at the Agriculture Research Station of Sarab Changaei. This experiment was a factorial on the basis of a randomized complete block design (RCBD) with four plant densities (6.5, 7.5, 8.5 and 9.5 plant/m2), three cor...
in order to study of hydropriming, planting depth and nitrogen split application effect on yield and yield components of double cross hybrid of corn, an experiment was carried out as factorial based on randomized complete block design (rcbd) with four replications. nitrogen split application included (400 kg/ha at sowing date, 100 kg/ha at sowing date and 300 kg/ha 25 to 50 days after sowing da...
