plant spacing and nitrogen are the most important factors for increasing tuberose quality and quantity. in this study, field experiment carried out as factorial randomized completely block design (rcbd) in 3 replications. different levels of nitrogen (0, 50, 100, 150, 200, 250 kg/ha) of ammonium nitrate was used. second factor was different plant spaces (10, 15, 20 and 25 cm). results showed th...

In order to evaluate the effects of sowing date and intra rows spacing on yield, yield components and some phytochemical characteristics in Roselle, a field experiment was conducted as a split plot layout based on randomized complete block design with three replications in 2013 and 2014 growing seasons. Five sowing dates were considered as the main plots (11th and 30th of March, 14th of April, ...

spreading faba bean (vicia faba) cultivation can enhance the sustainability of cropping systems and have other important benefits. however, there is little information on the various aspects of production management for this crop. then, this experiment was carried out to study the response of some agronomic characteristics of faba bean cv barakat to inter- (15, 30, 45 and 60 cm) and intra-row (...
