Opis:
The article analyses the condition of organic farming in Poland on the basis of the data published by the Agricultural and Food Quality Inspection, the Central Statistical Office and available literature sources. The aim of the study was to assess the condition and prospects for the development of organic produc-tion in Poland. The results of the analysis indicate that there is a growing demand for organic products among consumers, which may contribute to the development of organic farming and an in-crease in the processing of organic products. However, in recent years, a decline in the number of organic farms and the total area of organic farming has been observed. Fodder plants, cereals as well as meadows and pastures are predominant in the structure of crops. Orchards, berries and vegetable cultivation as well as industrial crops are of lesser importance. Poultry, sheep and dairy cattle are predominant in organic livestock farming, whereas goats and cattle intended for meat account for a lower percentage. Among the organic agricultural products milk and dairy products are produced in the greatest quantities.

Opis:
Appropriate agrotechnical measures make it possible to optimise plant cultivation and obtain yields of the highest quality with an appropriate economic production index. The aim of the study was to evaluate different sowing density and row spacing on the morphological and mechanical properties of white lupine (Lupinus albus L.) seeds. The field experiment was conducted at the Experimental Station for Variety Evaluation in Przecław (50°11'25.2" N, 21°28'55.0" E). The experiment was established at two row spacings (15 cm and 30 cm) and three sowing densities (60, 75, 90 plants per m2). Mechanical parameters evaluated included destructive force FD (N), relative deformation DR (%) and destructive energy ED (mJ). Seed morphological properties such as weight, length and width were also assessed. Sphericity was also calculated. In the present study, improvements in the mechanical properties of the seeds were obtained by increasing the plant density per unit area of the experiment. In the case of morphological characteristics, only the weight of the analysed lupine seeds changed significantly as a result of row spacing. On the other hand, sowing density did not significantly affect morphological traits. of white lupine seeds. Apart from the spacing and sowing density of plants, the weather conditions in particular years of research were an important factor determining the properties of seeds. Determining the optimum sowing density and row spacing in the field contributes to the optimisation of the production process. Quasi-static mechanical tests are often used to obtain reasonable data on the physical properties of plant materials.

Opis:
Pea is one of the most important legumes grown in the world. The seeds are used for food production and animal feed. The problem with its cultivation is the low yield and sensitivity to the course of the weather. The important factor is to determine the optimal sowing rate and row spacing, especially for new cultivars of pea. Therefore, research was undertaken to assess the effect of row spacing and sowing density on selected physiological parameters, yielding, and structural elements of peas cv. ‘Batuta’ in Poland. The results of the research showed that the row spacing and sowing density determine the values of plant physiological parameters, yield of pea seeds and protein content. The increase in plant density in the canopy caused a decrease in the measured parameters of chlorophyll fluorescence, such as maximum quantum yield of photosystem II (Fv/Fm) and maximum quantum yield of primary photochemistry (Fv/F0) and performance index (PI). The leaf area index (LAI) was lower with a wider row spacing. Row spacing and plant density determined yield of pea seeds, number of pods and seeds per plant and weight of seeds per plant. Wider row spacing resulted in a decrease in the protein content in seeds, while an increase in sowing density from 70 to 110 m2 caused its increase. The course of the weather during the vegetation period of plants significantly influenced the obtained results.
