Abstract

In order to decreasing the chemical fertilizer application in low-input and sustainable agricultural systems, a field experiment was carried out to evaluate the effects of different irrigation intervals along with separately and integrative application of chemical and biofertilizer on the quantity and quality of camelina (Camelina sativa L.).
Material and methods
The study was carried out as a split plot based on a randomized complete block design (RCBD) with 18 treatments and three replications at the Saqez city, Iran in 2022 growing season. The main factor was three irrigation intervals including without irrigation (rainfed conditions), irrigation after 10 and 20 days. Also, the sub-factor was different fertilizer sources including non-application (control), 100%chemical fertilizer, biofertilizer, biofertilizer+ 25% chmical fertilizer, biofertilizer+ 50% chemical fertilizer and biofertilizer+75% chemical fertilizer.
Results
The results demonstrated that the highest (457.81 kg ha-1) and lowest (186.29 kg ha-1) seed yield of camelina was obtained in 10 days’ interval irrigation following integrative application of biofertilizer+ 75% chemical fertilizer and rianfed conditions without fertilization. The highest oil content (37.88%) and oil yield (173.65 kg ha-1) was observed in 10 days’ interval irrigation following integrative application of biofertilizer+ 75% chemical fertilizer. The chemical analysis showed that linolenic (30.59-34.58%), linoleic (16.92-19.29%), oleic (14.16-17.36%) and eicosenoic acid (8.93-11.76%) were the main fatty acids compounds of camelina oil. The maximum content of oleic, linoleic and linolenic acids obtained in in 10 days’ interval irrigation following integrative application of biofertilizer+ 75% chemical fertilizer.
