Opis:
The study took place between 2012 and 2014 in Falenty near Warsaw, Poland, as part of a long-term scientific experiment (first began in 1987) using the randomized block method. All blocks were irrigated until 2008. In 2009 each block was divided into two areas: irrigated and non-irrigated. The study involved four levels of inorganic nitrogen fertilizer and two levels of mixed inorganic and organic fertilizer in the form of fermented cattle urine. The soil in all experimental plots was characterized by low levels of zinc, ranging from 7.6 to 16.7 mg Zn∙kg–1 dry matter. Much lower Zn content in both soil layers of all irrigated plots was associated with increased yields on these plots, regardless of the level and form of fertilizer. The content of Zn in soil and sward in 2014 year was significantly lower compared in 2012. Inadequate levels of zinc for ruminant nutrition were observed in the sward from all plots (15.4–28.8 mg∙kg–1 dry matter). The higher content of zinc was found in sward harvested from the plot, which was not fertilized with phosphorus. The long-term inorganic and fermented urine fertilization resulted in very low zinc content in the soil and meadow sward.

Opis:
The aim of this study was to determine the effect of 20-year-long irrigation of permanent grasslands with potato starch and brewery wastewater on the botanical composition of sward, yield and nutritional value of hay. The experiment was conducted in the center for wastewater treatment and use in Mątwica-Kupiski (668 ha), which has been equipped with facilities for flood irrigation with wastewater since 1965. Potato starch and brewery effluents were mixed in a storage reservoir at a ratio of 1:0.4. Meadow sward was irrigated with wastewater in autumn and after the first harvest, at an annual dose of 200 – 300 mm. On average, wastewater contained (mg dm-3): N – 223, P – 48, K – 285, Ca – 80, Mg – 46, Na – 68. Before the first harvest in 1998, 2003, 2008, 2013 and 2018, the floristic composition of meadow sward was determined on an 11-degree scale by the Klapp method. Yield was determined in trial plots. Based on the percentage of dominant species (above 20% share of the sward), several floristic types of grassland communities were identified. Herbage samples were collected for detailed botanical and chemical analyses according to the floristic composition of the identified grassland communities. Chemical analyses of plant material were performed by standard methods. Longterm irrigation of meadow sward with wastewater contributed to the development of agronomically important plant communities, except for the Agropyron repens community in the western part of the research site. The yield of grassland irrigated with wastewater, regardless of a floristic type, was 2- to 3-fold higher than the yield of non-irrigated grassland. Hay harveste in wastewater-irrigated meadows met the crude fiber, ash and fat requirements of animals. The total protein content of hay remained within the recommended limits for high-quality fodder, except for the Alopecurus pratensis + Agropyron repens community.

This paper presents the process and results of the implementation of the irrigation system on meadows in Tanzania. The irrigation system was im- plemented in 2010 and 2012 as an element of two development projects co-financed by Ministry of Foreign Affairs of the Republic of Poland un- der the Polish Development Programme. During the first phase ( 2010) the earth water reservoir and the canal carrying water on a meadow were built and the irrigation system based on Amirite sprinklers was installed . In 2012, the concrete water tanks were built , and two hose reel irrigators were bought and put in action . The i mplementation of the irrigation system allowed for a significant increase in the production of hay. In the analyzed time period (from 2008 to 2012) the increase in yields of hay from 34.7 tons to 237.3 tons was noticed. The resulting implementation of the irrigation project increase hay production should be considered valuable, especially under the conditions of advancing climate change and its potential impact on the reduction of agricultural production in Tanzania.

Opis:
Badania prowadzono latach 2008-2010 na łące trwałej położonej na glebie mineralnej, zaliczanej do czarnej ziemi zdegradowanej. Prowadzono trzykośny system użytkowania. Celem pracy było rozpoznanie wpływu nawożenia oraz uwilgotnienia gleby na plonowanie runi łąkowej oraz masę korzeni zlokalizowanych w górnych warstwach gleby łąki. Wilgotność na obiektach deszczowanych utrzymywano na poziomie 60-100% PPW, stosując deszczowanie. W każdym pokosie określano plony runi, a jesienią w 2008 i 2010 r. biomasę korzeni. Próbki gleby o objętości 0,5 dm³ do oznaczania masy korzeniowej pobierano z górnych warstw profilu glebowego 0-10 i 10-20 cm, i po wypłukaniu oraz wysuszeniu ważono. Masę korzeniową oraz plony runi łąkowej poddano ocenie statystycznej. Zwiększenie dawki azotu powyżej 60 kg·ha-¹ powodowało istotny wzrost plonowania runi łąkowej. Nawodnienie nie zawsze dawało wyraźny efekt w postaci wzrostu plonowania, co było związane z wysoką sumą opadów atmosferycznych, które w 2010 r. spowodowały wyższe plony na niektórych obiektach bez nawodnień w stosunku do obiektów nawadnianych. Nie stwierdzono wyraźnego wpływu nawożenia na masę korzeni. Ilość masy korzeniowej w warstwie gleby 0-10 cm z obiektów nienawadnianych była większa w porównaniu z obiektami nawadnianymi, a w warstwie 10-20 cm obserwowano tendencję odwrotną.
The study was carried out in the years 2008-2010 on permanent grassland situated on mineral soil classified as degraded black soil. The vegetation was cut three times a year (season). The aim of the study was to recognise the impact of fertilisation and soil moisture on the yield of meadow sward plants and root mass in the upper soil layer. Soil moisture was maintained at a level of 60-100 of field water capacity by sprinkler irrigation. Yields of the sward were measured in each swath and root mass was determined in autumn 2008 and 2010. Soil samples of 0.5 dm³ volume were collected from the top layer of soil profiles (0-10 and 10-20 cm) to examine the root mass. Samples were rinsed, dried and weighed. Root mass and yields of meadow sward were subjected to statistical analysis. Increase of N dose above 60 kg·ha-¹ significantly increased sward yield. Irrigation had no clear effect on yield. This was a result of unusually high precipitation in 2010 that increased the yields in some not irrigated experimental fields. The influence of fertilisation on root mass was not found. Root mass in the 0-10 cm layer from not irrigated fields was larger than that in irrigated fields. In the 10-20 cm soil layer the opposite trend was observed.
