in order to investigating the effects of planting date and harvest time on the quality performance of pear millet, an experiment was conducted in agriculture research station of gorgan in a randomized complete block design with four replications and factorial arrangement. this experiment included five planting dates (may 5th, may 25th, june 14th ,july 4th, july 24th) and three harvest times (90...

Yield and relationships among head traits were recorded in order to better understand the effects of planting date and cultivar selection on crop quality characteristics and to help increase the efficiency of cultivar development, evaluation, and selection. A total of seven cultivars of fresh market-type cabbage (Brassica oleracea L., Capitata Group) were planted in May and June of 1999 and 200...

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,...

An improved process for slip casting ceramic articles that does not employ parting agents and affords the casting of complete, detailed, precision articles that do not possess parting lines. A wax pattern for a shell mold is provided, and an aqueous mixture of a calcium sulfate-bonded investment material is applied as a coating to the wax pattern. The coated wax pattern is then dried, followed ...

[Background] Wheat is the most important food crop, with largest planting area in world. However, production process, due to species degradation and occurrence of new diseases, antigens old varieties are lost, resulting reduced yield even no harvest. In order ensure stable increase wheat, need be updated time. By using different seasons places carry out additional generation breeding two...
