Under irrigation and in double-cropping system, a large amount of plant residue remains after harvest that along with the limited time for residue decomposition and complete seedbed preparation, necessitates reduced tillage and special residue management. In the present study, the effects of various seedbed preparation methods on vegetative growth, yield components and seed and oil yields of su...
To determine the effects of different intensities of leaf removal at different reproduction stages of sunflower on seed yield and oil percentage, and the most sensitive stages to defoliation, an experiment was carried out by split-spilt plot design in randomized complete block with 3 replications at research farm, College of Agric. Urmia University, in 2004. The main factor, sub factor and sub-...
A greenhouse experiment was conducted in order to evaluate the influence of different nitrogen (N) and zinc (Zn) levels on yield, yield components, seed quality and N and Zn contents of two cultivars of rapeseed (Brassica napus L.). In this study, two cultivars of rapeseed (Talayeh and Opera), three N levels (100, 200 and 300 mg/kg) and three Zn levels (0, 5 and 10 mg/kg) with three replication...
Fertilizer management plays an important role in obtaining satisfactory yields from maize. In addition, fertilizer management is essential for achieving sustainable agriculture and protecting the environment. This research was conducted by split plot experiment based on randomized complete block design with four replications. Main factor was integrated with chemical and biological fertilizers i...
safflower oil seed has high adaptability to different kinds of abiotic stresses such as drought and salinity. the aim of this study was to evaluate the effects of drought stress at different phenological stages on relative water content (rwc), leaf canopy temperature, seed yield and its components in spring types of safflower. the study was carried out in east azarbaijan research center for agr...
Irrigated rapeseed (Brassica napus L.) cultivation is currently expanding in rotation with winter cereals in Iran where its reproductive growth is often exposed to water deficit in many parts, particularly in the south. A two growing seasons (2006-2008) field experiment was conducted at the Experimental Research Center, Shiraz University to study the effects of water stress at different growth ...

Development of oil seed crops is the most important aim in our country to achieve self sufficiency. This study was conducted to assess the suitability of oil brassicas species in rain-fed warm areas of Iran. This research was performed for three years in Agricultural Research stations of Gonbad (Golestan). Twenty varieties and hybrids (B. napus, B. rapa, B. juncea ) were compared in RCBD with t...
in order to analyze general and specific combining abilities and gene effects in sunflower for some agronomic traits, five cms lines and four restorer lines (tester) were crossed in a line × tester scheme. hybrids were evaluated in a randomized complete block design with three replications in the agriculture research station, university of tabriz, in 2009 and 2010 growing seasons. plant height,...
