background & aim: german chamomile is one of the most important medicinal plants. so, assessment of genetic diversity and relationship among the traits are very essential in chamomile breeding programs. determination of the best indirect selection criteria for genetic improvement of essence percent and dry flower yield of german chamomile (matricaria chamomilla l.) populations was investiga...

this experiment was carried out in factorial arrangement based on randomized complete block design with three replications in agricultural and natural resources research center of markazi province, arak (iran) during 2008-2009 growing season. three application rates of sulphur (s1=0, s2= 40 and s3=80 kg/ha) and three rapeseed varieties (okapi, modena and licord) comprised the experimental facto...

An experiment was carried out in the field laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh, to investigate the flowering pattern, floral and pod abscission under untreated and GABA (mixture of GA3 and Abscissic acid) treated soybean and their trends concern to yield. The variety of soybean PB-1 (Shohag) was used in the investigation. GABA at 0.5, 1.0 ...

introduction: more plains of iran are located in arid and semi-arid regions and so agricultural production systems depend heavily on water. recently, the reduction of water resources has become a serious threat for crop production such as cotton planting. therefore, application of low irrigation methods can be an appropriate method to cope with mentioned condition. in addition, it is vital to i...
