The impact of foliar spray fertilizers (Aton Az) on the resistance of spring barley (Hordeum vulgare L.) against to individual and combined UV-B radiation and drought effects were investigated. Barley seeds were sown in pots prepared with neutral pH peat substrate. When the 2nd true leaf unfolded, i.e. 7 days after germination, the first spray with microelement and free amino acid fertilizers was carried out; two days after this application, the different irradiation (1 and 3 kJm–2 d–1) UV-B doses and drought effects were started. Exposure lasted for 6 days. The main characteristics of all investigated indicators were assessed at the end of exposure. The largest positive effects of fertilizers on the photosynthetic rate and water use efficiency of barley were found solely under the impact of drought. Foliar spray fertilizers decreased oxidative stress injury in the leaves by decreasing the malondialdehyde content under solely effects of drought and UV-B radiation, while under the combined effect of the mentioned stress factors, the changes were statistically insignificant. A stronger positive impact of foliar fertilization was detected on the content of photosynthetic pigments (a and b) at solely UV-B radiation effect than at combined effect of investigated factors, when significant changes were detected only in individual cases.

Nutrient management practices that concurrently improve soil properties and yield are essential for sustaining barley production. This study was conducted to evaluate the impact of balanced nitrogen fertilizer application involving farmyard manure (FYM) and residue management. The experiment had a factorial arrangement of five levels of mineral N and two organic fertilizer sources. The five levels of N fertilizer were applied in three replicates in combination with each of the two organic sources and a control (without organic source). Average plant height (PH), grain yield (GY), and straw yield (SY) were significantly (P <0.05) influenced by the main effect of N application and organic source; however their interaction was insignificant. The highest grain yield (103%) was obtained with 120 kg N compared to the control. The grain yield increased by 23.4% and 44% with FYM and residue, respectively, against the untreated control.
