Opis:
Chilling stress is of major limiting factors influencing the growth and development of warm-season crops like cucumber. In this research, the possibility of chilling tolerance of cucumber seedlings was investigated through employing the drought and low-temperature pretreatments. The factorial experiment consisted of two factors including cucumber cultivars (i.e. ‘Super Dominos’ and ‘Super Star’) and hardening treatments (control, low temperatures at 10°C, and 15°C and drought simulated by 10% and 20% PEG) based on completely randomized design (CRD) in 3 replications. After applying treatments and providing them 48 h opportunity to be recovered, the seedlings were subjected to 3°C for a six-day period and 6 h for each day. All hardening treatments improved seedlings’ growth, chlorophyll content, total phenol (TP) and antioxidant enzyme activities, while reducing chilling injury index and malondialdehyde (MDA) content. Comparing to temperature hardening, the drought pretreatment showed to have a better effect on inducing the chilling tolerance into cultivars. Overall, the results of this experiment showed that employing drought and low-temperature pretreatments enabled cucumber seedlings to mitigate the harmful effects of chilling.

Opis:
In order to evaluate the yield, yield components and some physiological and qualitative traits of corn treated with nitrogen fertilizers (biological, chemical and integrated), a field experiment was conducted at the Agricultural Research Station of Khorramabad during 2016 growing season. Treatments were arranged in a complete randomized block design with four replications. Experimental treatments consisted of 100% chemical fertilizer (urea), bio-fertilizer (nitroxin), integration of bio-fertilizer + 25% chemical fertilizer, integration of bio-fertilizer + 50% chemical fertilizer, integration of bio-fertilizer + 75% chemical fertilizer and the control. Results showed that the effect of different treatments of fertilizers on all measured traits, except for number of rows in each ear and carotenoids, was significant. The results indicated that integration of bio-fertilizer + 75% chemical fertilizer affected the highest grain yield (9.31 t ha–1), dry biological yield (20.96 t ha–1), number of kernels in each row (41.67), plant height (201.02 cm), hectoliter weight (0.82 g cm–3), chlorophyll b (0.43 mg g–1 FW), total chlorophyll (1.1 mg g–1 FW) and leaf area index (LAI) (4) and there was no significant difference among this treatment and 100% chemical fertilizer (N) and integration of bio-fertilizer + 50% chemical fertilizer treatments in all measured traits. The greatest harvest index (45.8) and grain protein-content (9.1%) resulted from the integration of biofertilizer + 50% chemical fertilizer treatment. Also the highest 1000-grains weight (281.13 g) and chlorophyll a (0.66 mg g–1 FW) were caused by 100% chemical fertilizer (urea) treatments. Results showed that integration of bio-fertilizer + chemical fertilizer could be considered as a means to reduce the consumption of chemical fertilizers for sustainable agriculture.
