Opis:: 11Abstract. Maize, one of the most important cereals species grown in Poland, use large quantities of nitrogen, but water defi-cit through the vegetation period might lead to yield reduction and diminish nitrogen uptake. The aim of the study was to char-acterize the productivity of the crop, depending on its nitrogen and water use efficiency. In two locations, in Western and Eastern Poland, eleven-year field experiments with maize grown for grain were conducted. Maize was fertilized with increasing rates of ni-trogen: 50, 100, 150, 200 i 250 kg N ha-1. It was found, that grain yields of maize raised statistically significant up to 8.03 tha-1 under 150 kg Nha-1. Such a dose guaranteed: nitrogen uptake 182 kg Nha-1, nitrogen use efficiency 121%, nitrogen surplus -32 kg Nha-1, water use efficiency 14.5 kgha-1 mm-1, and nitro-gen utilization efficiency 43 kgkg-1. Increasing nitrogen doses over the years was not justified because maize productivity was limited by water availability under higher nitrogen rates.

Opis:: Based on FAO data, the paper presents trends in nitrogen (N) input and output in Poland. As N input (Ninp), nitrogen from mineral fertilisers, manure application, biological fixation, and deposition was included. The N outputs (Nout) include the N contained in crop harvest (main products and by-products). The trend analyses were carried out for the period before (1961-1989) and after (1990-2018) the changes in the political and economic systems. Additionally, trends in the nitrogen use efficiency (NUE) and nitrogen surpluses (NS) are presented for these periods. In both compared periods, the mean values of N budget indicators in Poland were (kg N∙ha-1 UAA): Ninp 120 and 125, Nout 61 and 84, NS 60 and 41 and NUE 53 and 67%, respectively. The estimated Ymax, which represents the Nout value reached at saturating N fertilisation, reached the values of 127 and 263 kg N∙ha-1 UAA in these periods. The difference in these values suggests a significant impact of agronomy improvement on Nout in the recent period. The trends of nitrogen within 16 regions in period 2002-2019, based on national data, resulted in a significant variation in N indicators. The values found were in the following ranges (kg N∙ha-1 UAA): Ninp 78-167; Nout 62-99; NS 15-83 and Ymax 139-317. The NUE ranged from 50-81%. The obtained results indicate that in Poland and its regions there is still a need to improve of the nitrogen efficiency.

Opis:: This paper presents the results of 11 years of field experimentconcerning winter oilseed rape in Eastern Poland. Theaim of the study was to characterise rape production dependingon the nitrogen and water use efficiency. Oilseed rape was fertilisedwith increasing doses of nitrogen, i.e. 50, 100, 150, 200and 250 kg N ha-1. It was found that rapeseed yields increasedstatistically significantly to 3.33 t ha-1 at a rate of 200 kg N ha-1.This dose guaranteed: nitrogen uptake of 155 kg N ha-1, nitrogenuse efficiency of 78%, nitrogen surplus of 45 kg N ha-1, wateruse efficiency of 8.4 kg ha-1 mm-1 and nitrogen utilisation efficiencyof 22 kg kg-1. Increasing the nitrogen rate in the long termto 250 kg N ha-1 proved to be unjustified because it did not causea significant increase in the yield or water use efficiency, while itsignificantly increased the nitrogen uptake, its surplus in the soiland reduced the efficiency of nitrogen from fertilisers utilisation.

Opis:: The article reviews one of the important problems of water usage – operational management of irrigation. The article discusses a methodological approach to the estimation of economic efficiency of water usage in the conditions of climate change in the territory concerned. So far, there has not been a simple method to determine this indicator. When assessing climatic conditions, taking into account their influence on the productivity of agricultural crops, it is necessary to take into account meteorological factors that have a decisive influence on the development of agricultural crops and, accordingly, determine their yield. These include primarily heat and moisture. Moreover, it is necessary to take into account their possible negative influence on the development of plants, considering that for each crop a certain optimum regime of temperature and soil moisture is required in different phases of its growth. To assess climatic conditions taking into account the potential crop productivity, we can use the CPA formula. Calculations have shown a close relationship between the CPA and the yield of agricultural crops. Correlation coefficients of the obtained bonds vary from 0.85 to 0.98 depending on the culture and the territory.

Opis:: Nitrogen (N) is an essential macronutrient for the growth and development of plants, but excessive use of nitrogen fertiliser in agriculture can result in environmental pollution. As a preferred nitrogen form, ammonium (NH4+) is absorbed from the soil by the plants through ammonium transporters (AMTs). Therefore, it is important to explore AMTs to improve the efficiency of plant N utilisation. Here, we performed a comprehensive genome-wide analysis to identify and characterise the AMT genes in barley (HvAMTs), which is a very important cereal crop. A total of seven AMT genes were identified in barley and further divided into two subfamilies (AMT1 and AMT2) based on phylogenetic analysis. All HvAMT genes were distributed on five chromosomes with only one tandem duplication. HvAMTs might play an important role in plant growth, development, and various stress responses, as indicated by cis-regulatory elements, miRNAs, and protein interaction analysis. Further, we analysed the expression pattern of HvAMTs in various developmental plant tissues, which indicated that AMT1 subfamily members might play a major role in the uptake of NH4+ from the soil through the roots in barley. Altogether, these findings might be helpful to improve the barley crop with improved nitrogen use efficiency, which is not only of great significance to the crop but also for land and water as it will reduce N fertiliser pollution in the surrounding ecosystem.

The article presents the cases of determining the adjacency levy based on the example of selected province. The work illustrates how to enter these charges and their impact on the development of local real estate markets. Selected cases relate to the development of technical infrastructure, emerging on both needs of the development companies as well as individual people. In Poland there is a lack of a clear policy on such regulations, although there are paramount rules, which, however, only apply of when the fee was determined. These rules are the basis of the appeal processes and compensation, that is why part of the municipalities of resigns gaining measures. Paper shows the cases of private infrastructure development financing and co-financing from the European Union. Also were analyzed, local approach to the problem, both in the case of the establishment of a sewage system and processes merge and split, or the creation of new roads. The last part of the paper is focused on land use efficiency in presented area and its effect for further regional politics. The last part of the article shows the real growth in property prices is not only due to its division but above all, changes in local land development plan of the area and is here that municipalities should look for your income

Opis:: Six experiments were conducted for the enhancement in seed cotton yield by increasing water use efficiency and water savings in case of different planting methods of cotton (Gossypium hirsutum L.) crop during the years 2014 & 2015, at three different locations in cotton zone of Punjab (Pakistan) province. The planting methods were, flat planting and no earthing up, flat planting and earthing up after 1st irrigation, flat planting and alternate row earthing after 1st irrigation, flat planting in 112.5/37.5 cm apart paired rows and earthing up after 1st irrigation, ridge planting and bed planting. Cotton crop obtained a maximum benefit from the available water at all three locations in case of flat planting with alternate row earthing up (P3) by predicting a maximum water use efficiency up to 6.79 kg ha-1 mm-1and maximum seed cotton yield of 3432.50 kg ha-1. Maximum water savings of 25.60% was recorded in the same method (P3) during the year 2014, while minimum (-0.17%) was observed in ridge planting (P5) at location number 1 in the same year.

Opis:: In furrow irrigation, the maximum lateral movement of water in ridges is more desirable than the vertical downward movement. This can be achieved by compacting the furrows. Thus, the study examines the impact on furrow soil compaction by tractor wheel trafficking during mechanical operations in the different soil types. In this experiment, the three-wheel tractor compaction includes: 1) control (no soil compaction), 2) compaction through 3-wheel tractor passes, and 3) compaction through 6-wheel passes under three different soil textural classes such as: clay loam, silty clay loam and silty loam soils. The impact of various treatments on clay loam, silty clay loam, and silty loam under 3- and 6-wheel passes showed increased bulk density (7–12%), field capacity (9–19%), ridge storage efficiency (35–38%), water use efficiency (16–20.5%) and decreased soil porosity (7–16%), infiltration (8–20%), and furrow storage efficiency (28–41%) over the control. This study shows comparable results of 6-passes with other studies in which more than 6-passes were used to compact the soil. This study suggested that farmers can maximise water use efficiency by compacting their furrows using 6-passes tractor trafficking.
