This paper presents the results of a 3-year field experiment conducted in north-eastern (NE) Poland to determine the influence of the autumn application of foliar macronutrient and micronutrient fertilizers (control, one application in BBCH (Biologische Bundesanstalt, Bundessortenamt and Chemische Industrie) stage 16 (six leaves unfolded)), two applications in BBCH stages 14 (four leaves unfolded), and 16 (six leaves unfolded) on the growth and development of winter oilseed rape plants, nutrient accumulation, overwintering success, yield components, yield, nutritional value (crude fat content, fatty acid concentrations), and feed value (total protein content, concentrations of acid detergent fiber and neutral detergent fiber, quantitative and qualitative composition of glucosinolates) of seeds. When applied in BBCH stages 14 and 16, foliar fertilizers stimulated the development of leaf rosettes, increased the accumulation of minerals in aerial rosette parts (N, K, and Mg) and roots (K, Cu, Mn, and Fe), and contributed to the overwintering success of winter oilseed rape plants (by 8–11%). The application of foliar macronutrient and micronutrient fertilizers in autumn increased seed yield (by 0.25 Mg ha−1), contributed to a significant increase in the crude fat content of seeds (by 1.3–7.4 g kg−1 dry matter (DM), increased the content of oleic acid, decreased the concentration of linoleic acid, and increased the content of glucosinolates, mostly the alkenyl fraction with antinutritional properties.

This paper presents the results of a 3-year field experiment conducted on soil with moderate levels of boron (B) in north-eastern Poland to determine the influence of foliar application of B (0, 150 and 300 g ha-1) on the yield components, yield, mineral composition, nutritional value and feed value of winter oilseed rape seeds. Foliar application of B at the beginning of bud formation in winter oilseed rape increased seed yield by 0.19 (3%) at the lower B fertilization level to 0.26 Mg ha-1 (4%) at the higher B fertilization level. The observed increase in the yield of winter oilseed rape seeds in response to foliar application of B can be attributed to this micronutrient’s positive influence on seed production in siliques. Foliar fertilization with B increased B content and decreased Zn and Fe levels in the seeds of winter oilseed rape. When B fertilizer was applied at the rate of 150–300 g ha-1, the N and Ca content of the evaluated seeds increased. The fertilizer improved the nutritional value (crude fat content, fatty acid concentrations) of seeds, but deteriorated their feed value (total protein content, acid detergent fiber concentrations, neutral detergent fiber concentrations, quantitative and qualitative composition of glucosinolates).

Medicago Sativa L

This research was conducted to determine performances of seven alfalfa cultivars with different fall dormancy rates in terms of dry matter yield and some quality parameters under Mediterranean conditions throughout the years of 2007-2009. In the study, cultivars were evaluated for dry matter yield (DMY), leaf/stem ratio (LSR), crude protein (CP) content, crude protein yield (CPY), acid detergent fiber (ADF), neutral detergent fiber (NDF), digestible dry matter (DDM) content and relative feed value (RFV). According to average of two year results, there were significant differences among alfalfa cultivars in terms of all characters studied. Mean DMY, LSR, contents of CP, ADF, NDF, DDM and RFV were determined as 18.147 t ha-1, 0.82, 17.4 %, 41.0 %, 49.0 %, 56.9 % and 114. The highest DMY averaged over two years was obtained from cultivar Nimet while lowest one was obtained from Magnum 5. As a dormant cultivar, Magnum 5 was superior in terms of LSR and CP content to the other alfalfa cultivars and it was lower in ADF and NDF content than the others. It was concluded that cultivar Nimet with the highest DMY and CPY yields can be recommended as a non-dormant cultivar for farmers in regions of Turkey with the Mediterranean climate.

The aim of the research was to determine the forage yield and quality of thirty alfalfa (Medicago sativa L.) genotypes. Plots were established in 2014 in Isparta, Turkey, in a randomized complete block design with 3 replicates. Five cuttings were done during the 2015, 2016 and 2017. The dry matter yield (DMY), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL) and relative feed value (RFV) were determined. According to the three years average results, significant differences were determined for all parameters. Alfalfa genotypes viz., Cay-1, Cay-2, Keciborlu-1 and Keciborlu-3 were selected for alfalfa breeding program due to their superior yield and quality features.

In this study, the agricultural inputs, energy requirements and costs associated with the production of semi-dwarf (PR45 D03 and Avenir) and long-stem (Visby) cultivars of winter oilseed rape were optimized in an experiment with 35-1 fractional factorial design. A field experiment was carried out in the Agricultural Experiment Station in Bałcyny (north-eastern Poland) in 2008–2011. The study investigated the responses of two morphotypes of hybrid cultivars of winter oilseed rape to key yield-forming factors (seeding date, seeding rate, nitrogen fertilization) and yield protection factors (fungal disease control). Agronomic inputs were tested at three levels. Our findings indicate that production technologies (characterized by a different intensity of agricultural inputs) should target the specific requirements of winter oilseed rape cultivars. Semi-dwarf cultivars of winter oilseed rape (PR45 D03 and Avenir) were characterized by higher yield potential at different input levels than the long-stem cultivar (Visby). Semi-dwarf cultivars required higher levels of agricultural inputs than the long-stem cultivar. Semi-dwarf cultivars grown in high-input technologies were characterized by the highest energy efficiency ratio. In contrast, the long-stem cultivar was characterized by the optimal energy input-energy output ratio in the low-input technology. Regardless of cultivar, high-input production technologies were more profitable because the resulting increase in seed yield significantly outweighed the rise in production costs.
