Since the conventional esterification method requires longer processing time and obtain low yield, the intensification of this process is still interesting subject to be investigated. To reduce the oil extraction cost from seeds which almost 70% of total processing cost, in situ esterification has been recently introduced. The objective of study was to produce biodiesel from rubber seeds oil th...

The experiment was investigated to survey of yield and yield components of sunflower cultivars under drought stress in 2012 in Kabootatabad of Esfahan farm. An experiment was conducted in split plot and was designed in randomized complete block with three replications. Irrigation was as main plots in 3 levels (control (normal irrigation), irrigation of 130 mm evaporation from pan evaporation, i...

for investigation quantitative and qualitative properties of different lines and cultivars of rapeseed, 19 selected lines from advanced inbreeding progenies, and zarfam variety (as check), totally 20 lines and varieties, were evaluated in a randomized complete block design with three replications at the experimental field of seed and plant improvement institute in karaj, during 2005-6. morpholo...

In In order to investigating changes range of oil yield and percentage attention to plant density on three varieties of black seed, an experiment was conducted in the form of factorial based on completely randomized block designs (RCBD) with 4 replications in Saat-Loui agricultural station of West Azerbaijan province. In this research, the first factor (A) contained two levels 20 and 40 cm inte...

background and objectives: drought stress is one of the most important environmental factors reducing growth and yield of crops, especially in arid and semiarid regions of the world. during drought stress, nutrient uptake diminishes due to rising of solute concentrations and so increasing of osmotic potential in the root zone. with increasing soil ph, micronutrient uptake decreases more than ot...
