in order to study the morphological characteristics affecting yield of echium amoenum under different nutritional treatments and different plant densities, a factorial experiment based on rcbd design with three replications was conducted at agricultural research station, ferdowsi university of mashhad, iran in 2011-2013 growing seasons. the experimental treatments were all combination of three ...

In order to evaluate the response of major nutrients concentration, uptake and their efficiencies of isabgol (Plantago ovata) to N fertilizer combinations and irrigation regimes, a field experiment was conducted at the agricultural research farm of Shahrekord University, 2009. The experiment was arranged as split-plot, in randomized complete block design with three replications. The irrigation ...

Soil and water salinity substantially constrain crop and biomass production. To investigate the changes in morphological parameters of lisianthus (Eustoma grandiflorum) cultivars under CaCl2 salinity conditions a greenhouse experiment was conducted. Cultivars namely, ‘Champagne’ (C1), ‘Lime Green’ (C2), ‘Blue Picotee’ (C3) and ‘Pure White’ (C4), were subjected to salt stress (0–30 mM CaCl2) in ...

Considering the increasing trend of saline land enhancement and lack of appropriate agricultural lands, identifying salt resistant plants such as fenugreek, which is an important medicinal plant, is important. To do so, a factorial experiment was conducted in the form of randomized complete blocks design with three replications on three fenugreek landraces (Yazd, Shiraz and Hendi) and five sali...

Estimation of genetic variation is very important in breeding programs and existing of high genetic variation lead to increase the response to selection. The objective of this study was to investigate genetic variation for agronomic traits and yield components in 12 alfalfa half-sib families. Thirty five individuals of each half-sib family were grown and analyzed basis of completely randomized ...
