Chamomile (Matricaria chamomilla L.) is one of the most important medicinal plants in Iran. The main objective of this study was to determine the effects of organic nutrients on the yield and oil content of chamomile. The experiment was conducted in the spring of 2010. The treatment groups consisted of vermicompost (0, 5, 10, 15 and 20 tons/ha) and the Aminol Forte sprays (no spraying or contro...

To investigate the effects of silicon on the growth characteristics and the reduction of the powdery mildew damage to Zinnia (Zinnia elegans Jacq. ʻMagellanʼ), an experiment was carried out as a factorial experiment in the form of a randomized complete block design with two factors including eight treatments and three replications. The first factor included silicon concentrations at four levels...

in order to investigate the effects of single irrigation amounts at different stages of rapeseed growth on yield and the improvement of water use efficiency and water productivity indices, this experiment was conducted as split plot arranged in a randomized complete block design (rcbd) with three replications during 2002-2003 for rainfed spring rapeseed variety (pf.7015.91= sarigol) at maragheh...

quantitative and qualitative characteristics and storability of behbahan landrace, selected population from behbahan landrace and primavera cultivar were compared for two years (2009-2010) at behbahan agriculture research station. field experiment was performed based on randomized complete block design containing four replications. seedlings were transplanted in mid-december. a split plot in ti...

To address the effect of organic fertilizers on rice insect pests and diseases, an experiment was carried out in Cuulong Delta Rice Research Institute (CLRRI) based on the randomized complete block design with three replications. The treatments were including a combination of four animal manure compost levels (2.5, 5.0, 7.5, 10.0 tons/ha) and four organic fertilizer levels (2.5, 5.0, 7.5, 10.0 ...

determination of cardinal temperatures during seed germination and emergence as well as the thermal time requirement for each stage is essential in crop management and modeling of plant growth and development. two experiments were conducted to predict cardinal temperatures and thermal time requirement for germination and emergence of chickpea genotypes. in the first experiment, seed germination...

drought stress is the most important factor that reduces yield in crops including chickpea and causes some changes in seed composition. this study was performed in order to evaluate the effects of drought stress and starter nitrogen fertilizer on four cultivars of chickpea. experiment was performed in a split-factorial using randomized complete block design with three replications. drought stre...

Since there is limited information on the simultaneous effect of drought stress and salicylic acid on yield and mucilagecontent of the medicinal herb, Plantago ovata Forssk is available, a pot experiment was conducted in factorial form basedon a randomized complete block design with three replications in Jiroft, Kerman Province, south of Iran. As the firstfactor, drought stress included four le...
