عنوان Study of changes in wheat biomass in two conventional and raised bed cropping systems under different irrigation regimes

نویسندگان Nadia Dorostkar - Alireza Pirzad

چکیده To evaluate effect of sowing systems and fertilizers on the growth of wheat (Triticum aestivum L.) an experiment was done based on Randomized Complete Block Design (RCBD) in three replications at Urmia University. Treatments were Conventional cultivation with full irrigation (CF), Conventional cultivation with deficit irrigation (CD), Raised Bed cultivation with full irrigation (RF), Raised Bed cultivation with deficit irrigation (RD) and Raised Bed cultivation Mycorrhized deficit irrigation (RMD). Leaf weight, stem weight and spike weight changes for all treatments had a cubic relationship with time. Initially, leaf weight showed an increase and then a slow decrease until stage 7. At the end of the growth period, it was accompanied by a rapid increase. For the raised bed planting systems, a rapid increase of stem weight was observed first until stages 2 and 3 and then a decrease until the end of the growing period. However, the stem weight at the end of the growing period was close for all treatments. In raised beds, for all three groups of Raised Bed cultivation, spike weight increase was obtained and then these values remained constant, but it also showed a decrease in the last two stages for Conventional cultivation.
