The objective of this study was to investigate the effect of exogenous application of salicylic acid concentrations on the physiological and biochemical traits and essential oil content of chamomile under normal and heat stress conditions as induced by delayed sowing. The experiments were conducted during 2011–2012 as a factorial using a randomized complete block design with three replications,...

to investigate the effects of sowing date on yield and quality of six forage maize cultivars in rasht region, a field study was conducted in 2010. the experimental design was a randomized complete block using a factorial arrangement with three replications. treatments consisted of four levels of sowing date (22 may, 3, 15 and 25 june), and six maize cultivars (sc 260, dc 370, sc 500, sc 647, sc...

In arid and semi-arid regions of the world bread wheat (Triticum aestivum L.) yield is highlylimited due to late season heat stress, mostly occurring during the reproductive phase. Hence thecurrent study was conducted to evaluate the effect of late season heat stress on grain yield andyield components of 20 spring bread wheat cultivars. For this purpose, a stripe block experimentincluding four ...

Different responses of plant genotypes to the change of environmental conditions have been the most important and challenging issue for plant breeders and agronomists for the selection of superior genotypes. Cumin is one of the most important medicinal and aromatic plants in Iran that are strongly affected by varying environmental conditions. This study was aimed to investigate E×SD interaction...

Coriander is an annual and herbaceous plant, belong to the apiaceae family. This plant is cultivated world widely. It is well known for having medicinal properties.

The experiment was carried out in research farm, Campus of Agriculture and Natural Resources, Razi University, Kermanshah, Iran. Coriand...

Germinant sowing is operational for tree nurseries in South Africa. The technique reduces seed costs for eucalypts and pines. Filled cell percentage is usually near 98%. Seed efficiency at many North American container nurseries can be improved by adopting either germinant sowing or single sowing technology. Tree Planters' Notes xx(x):xx; 199x. INTRODUCTION Managers at most container nurseries ...

To assess potential effects of seed limitation, characteristics of invader species and characteristics of established plant communities on recruitment success, we conducted a split-plot experiment factorially combining three weeding treatments corresponding to increasing successional age (regular weeding < cessation of weeding after three years < never weeded since sowing) with two seed limitat...

in order to study the effect of sowing methods and seeding rates on fodder yield and some agronomic characters of nikshahri alfalfa ecotype, an experiment was conducted in a split plot arrangement in randomized complete block design with four replications in the field of agricultural and natural resources center of baluchistan in iranshahr region. in this study, sowing methods: hand spread, 12 ...
