Lupine seeds are promising soy replacement in food products and feeds. Eighteen cultivars of blue lupine seeds were examined to indicate the one most favourable in protein content and quality. Two parameters were studied, i.e. total protein content (with the Kjeldahl method) and amino acids composition (with the ultra performance liquid chromatography technique). Both parameters studied were variable and depended both on the cultivar and on the place of cultivation. Protein content was in the range of 28-41% and the worst cultivar, regardless of cultivation place, was cv. Kalif (average total protein content 29.37 ± 1.14%), while the best cultivar...

Excessive nitrogen (N) and water input, which are threatening the sustainability of conventional agriculture in the North China Plain (NCP), can lead to serious leaching of nitrate-N (NO3--N). This study evaluates grain yield, N and water consumption, NO3--N accumulation and leaching in conventional and two optimized winter wheat-summer maize double-cropping systems and an organic alfalfa-winter wheat cropping system. The results showed that compared to the conventional cropping system, the optimized systems could reduce N, water...

Field experiments were conducted at three sites: Yangling (YL); Zhouzhi-1 (ZH-1) and Zhouzhi-2 (ZH-2) of the Loess Plateau during summer maize crop, to investigate the effectiveness of N-(n-butyl) thiophosphoric triamide (NBPT) and NBPT + dicyandiamide (DCD) with urea on reducing NH3 volatilization from different soils under different environmental conditions. Four treatments including control (no N), N-220 kg/ha, N-220 + NBPT and N-220 + NBPT + DCD were applied in two splits through the band placement method. Total NH3-N loss observed were 65.8, 40.5...

Potassium (K) in sugar beet can be partly replaced by magnesium (Mg) and sodium (Na). This hypothesis was verified based on 12 field experiments conducted on four farms in Poland during the seasons 2010-2012. The effect of different K, Na and Mg ratios in fertilizers applied in the total rate of 3205 mol/ha on beet yield (BY), storage root quality and white sugar yield (WSY) was determined. The tested K:Mg:Na cation ratios were as follows: 1:0:0; 1:0.11:0.09; 1:0.16:0.54 and 1:0.33:2.19. BY and WSY were affected by the total rate of the applied cations. The optimum ratio of K:Mg:Na was different with respect to the site and the growing season. The...

In a two-year pot experiment, the effect of five growing media on the growth, flowering, decorative value of Pelargonium peltatum cv. Maxime as well as on their uptake of the nutrients and heavy metals were studied. The media were prepared from four composts (made from: sewage sludge 70% or 35%, potato pulp 35%, straw 30% or sawdust 30%) and peat in 1:1, V:V ratio. In the 1st year of research 7-month-old composts and in the 2nd year 18-month-old composts were used. Plants cultivated in 7-month-old composts showed better growth-related parameters,...
Effect of genotype, flesh colour and environment on the glycoalkaloid content in potato tubers from integrated agricultureOriginal Paper

The main aim of the study was evaluation of the content of -solanine, -chaconine and total glycoalkaloids (TGA) in fourteen new potato cultivars with purple and red flesh in comparison with yellow- and white-fleshed control potatoes cultivated in a friendly way in integrated agriculture. The results were obtained from three-year trials on two locations. TGA levels in tubers'...
Correlation of extractable soil phosphorus (P) with plant P uptake: 14 extraction methods applied to 50 agricultural soils from Central EuropeOriginal Paper

The aim of this study was to test different soil phosphorus (P) extraction methods in relation to plant P uptake. A greenhouse pot experiment was conducted with spring wheat. The soils were extracted with the following methods/extractants: H2O, CaCl2, LiCl, iron oxide impregnated filter papers (Fe-oxide Pi), Olsen, calcium-acetate-lactate (CAL), cation and anion exchange membranes (CAEM), Mehlich 3, Bray and Kurtz II (Bray II), citrate-bicarbonate-dithionite, organic P, HCl, acid ammonium oxalate, total...
