Abstract

The objective of the present study was to identify the most salt-tolerant species among common vetch (Vicia sativa cv. Uludag), forage pea (Pisum sativum cv. Kirazli) and canola (Brassica napus cv. Bristol). To this end, the effects of salinity on the seedlings were determined, and four salt concentrations (0, 50, 100 and 150 mM NaCl) were evaluated. Seedlings were exposed to salinity stress for 45 days, and the seedling height, root length, shoot and root dry weight, leaf number per seedling, leaf area per seedling and Na, K and Ca content of the shoots and roots were determined. In addition, the K/Na and Ca/Na ratios were calculated. For all of the species, salt treatments significantly altered several characteristics of the shoots and roots. For instance, the Na content of the roots and shoots increased with an increase in the salt concentration, and the K and Ca content of the roots and shoots decreased. Furthermore, the results indicated that Pisum sativum cv. Kirazli was more resistant to salt stress than the other cultivars and can be cultivated on salty soils containing less than 100 mM NaCl.

Abstract

A field experiment was conducted in the Wielkopolska region at the Gorzyń Research Station, Poland (52.34°N, 15.54°E) in Central Europe. The study was conducted over a 3-year period (2017, 2018, 2019) as a two-factorial design with four replications in the RCBD. The aim of the research was to determine the effect of the cultivar (‘Bolero’, ‘Tytan’) and the inoculation (Nitragina–seeds inoculation, Nitroflora I–seeds inoculation, Nitroflora II–soil inoculation, HiStick® Lupin–seeds inoculation) on plant development, seeds chemical composition and yielding of narrow-leaved lupin. The weather conditions and experimental factors significantly influenced on productivity of narrow-leaved lupin ‘Tytan’. Drought during the growing season reduced seeds and protein yields. After inoculation of HiStck the seeds yield was significantly greater by 12.4% (p < 0.01) and the protein yield after application of Nitroflora I or HiStick by 13.9% (p < 0.01) and 19.2% (p < 0.01), respectively. Correlation coefficients showed strong relations between number of pods and seeds per plant in both cultivars regardless of the inoculation variant, however the strongest relations in both cultivar were proved on HiStick treatment.
