AB  - Parameters of light interception have an important role in plant growth and dry matter production. Those parameters are: leaf area index (LAI), cumulative interception (CI), light interception (I) and light use efficiency (LUE). The aim of the presented research was to investigate the effect of nitrogen nutrition on light interception parameters and dry matter production and their relationships. A field experiment with leek was set up under nitrogen fertilization on a cambic soil. Nitrogen was incorporated in soil either as one-off or split dose and during experimental period light interception parameters were measured and calculated as well as dry matter production. The obtained results showed that light interception parameters and dry matter production increased over the vegetation period. Comparison of applied fertilizers methods showed that the split application technique had a better effect on light interception parameters, dry matter production and growth than the one-off dose. The split dose method also achieved better nitrogen utilisation over the vegetation period than the one-off dose.

AB  - Partial root drying (PRD) is a new irrigation and growing plants technique which improves the water use efficiency without significant yield reduction. The aim of the presented paper was to investigate the effect of PRD on tomato plant growth, water-use efficiency (WUE) and ions content and distribution in tomato organs. Obtained results showed that as a consequence of PRD treatment the growth of the whole plants was reduced, but not fruit, although WUE was increased. Water potential values of PRD plants did not differ significantly from those of well-watered plants. These results support the hypothesis that a root-sourced signal and not a leaf-sourced signal may be responsible for triggering growth reduction in these PRD plants. Data for ions content (N, P, Ca, Mn, Zn and Cu) and their distribution between roots, shoots and fruits showed that PRD treatment only significantly changed N content in the shoots.

AB  - The objective of this research work was to determine correlative relationship between interception of photosythetically active radiation (IPAR or light interception, I) and nitrogen uptake(Nu) in order to determine nitrogen (N) status and monitoring N supply, during leek's crop vegetation period. The outset parameters were IPAR and leaf area index (LAI). Based on daily sum of global solar radiation (GS), dry matter production (W) was determined. Nu was defined according to relationship between Nu and LAI. Crop nitrogen demand (ND) and total N, as indicators of crop N-status, were determined. Nitrogen was applied in dose of 250 kg N ha(-1) (at once and half-spit dose). Relationships between mentioned parameters and on obtained equations could be used in hypothetical model of leek productivity created. Such model could allow monitoring leek productivity, crop N status and ND during ontogeny using simple and nondestructive measurements.

AB  - The aim of this project was to investigate the effect of nitrogen supply and light interception on productivity and growth,of leek (Allium porrum L.). A field experiment, with leek hybrid Alita (Royal Sluis, The Netherlands), was carried out with different levels of nitrogen fertilization. Nitrogen was applied as urea at a rate of 250 kg N/ha at different times: a) the whole amount applied just before transplanting (250+0), or twenty days after transplanting plants (0+250). and b) in split application (125+125), where half of the total amount was applied just before transplanting and the other half twenty days after transplanting plants. Plant analysis was based on the determination of the following crop growth, productivity and light interception parameters: dry matter production (W), leaf area index (LAI), light interception (1), cumulative light interception (CI), light use efficiency (LUE) and relative growth rate (RGR). Crop nitrogen crop status was determined as total nitrogen and critical nitrogen concentration in dry matter (Nt; Ne), nitrogen demand (ND) and nitrogen uptake (Nu). Results showed that N fertilizer increasing effect on all investigated parameters, but the effect was dependent on the applied dose of fertilizer. The biggest effect was measured with 125+125 kg N/ha splitted dose. Based on the obtained results and the relationships between light interception, dry weight and LAI, a model of growth and productivity of leek in field conditions was constructed. The main advantage of this model is that it allows monitoring of leek growth and productivity, N status and nitrogen demand during ontogeny using simple and nondestructive measurements.
