Opis:
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:
This study examined the effect of fertilisation with compost prepared from hygienised sludge with an addition of pine-tree bark and mulching with fresh forest ectohumus on selected growth parameters in two – and three-year seedlings of common beech and the occurrence of mites (Acari) in soil. The experiment was carried out in 2009-2010 in the Białe Błota forest nursery (Bydgoszcz Forest District) on proper rusty soil. The entire area of the experiment was irrigated with a stationary sprinkler. The beech seedlings on the plots where compost had been used as fertiliser were significantly taller than those growing on the plots where mineral fertilisers had been applied. Mulching increased the height of the seedlings significantly only in the last, third year of the study. The tallest three-year-old seedlings were found on the plots in which both of the tested procedures had been carried out. Neither of the factors under study had a significant effect on the diameter of the root neck in the second year of the nursery cultivation, but they increased it significantly in the third year. Fertilisation with compost with an addition of pine-tree bark increased the number of leaves per plant and the leaf area in two – and three-year-old seedlings. A beneficial and significant effect of mulching on these parameters was found in the third year of cultivation. A significantly positive effect of mulching on the mite gathering density was recorded in the second year of the nursery cultivation. However, both of the experimental factors had a positive effect on the occurrence of those arthropods in the third year of the study. Oribatid mites were the most numerous mite order and they were found in the greatest density on plots where mulching had been applied. Fertilisation and mulching increased the Oribatida/Actinedida ratio, which may indicate an improvement of the biological balance in the soil environment.

Opis:
The study of drip fertigation of winter squash ‘Gomez’ was conducted on the very light soil on the experimental field in Kruszyn Krajeński near Bydgoszcz in the years 2007 and 2008. The research was established as one-factorial, using the method of drawn blocks, in four replications. Drip fertigation (DF) as the liquid fertilization supplied nitrogen, potassium and phosphorus to the plants three times during growing season. As the control (DP), the drip irrigation combined with broadcast application was used. The potassium and phosphorus fertilization of control plots was applied before seed sawing. The nitrogen fertilization of control plots was provided in three single doses during vegetation. The liquid and powder fertilizations were performed at the same time. The complex fertilizer ‚Universol Blue’ (N:P:K = 18:11:18) was used. The dose of fertilizer was 3:2:3 (187.5:125:187.5 kg of NPK per ha). The irrigation was conducted using the drip line ‚T-Tape’. The liquid fertilizer was mixed by the ‚Dosatron’ dispenser. The irrigation started when the soil water pressure, measured with the tensiometers, was near - 0.04 MPa. In comparison to the control (powder fertilization), the drip fertigation (liquid fertilization) significantly increased marketable fruit yield, single fruit weight and fruit number. Most of the tested chemical components of ‘Gomez’ fruits (vitamin C, total sugar, monosaccharides, saccharose, total carotenoids and ß-carotin) were not significantly influenced by drip fertigation. However, the level of dry weight of winter squash ‘Gomez’ fruits was reduced by drip fertigation.

Opis:
The aim of the study was to determine the influence of drip irrigation on the nutritive value of winter squash ‘Rouge vif d’Etampes’ fruits analyzed directly after the harvest and after the storage. The plants were grown on the very light soil in the region of decreased rainfall amounts during the vegetation period. The field experiment was conducted in 2007-2008 at Kruszyn Krajeński near Bydgoszcz on the soil of quality class V-VI (very weak and weak-rye-soil-complex). The field water capacity in the soil layer 0-50 cm was 57.5 mm, while the effective useful retention amounted 29.3 mm. The experiment was designed as one-factorial trial in four replications; drip irrigation as the experiment factor was applied. As the control the plots without irrigation were considered. The single plot area was 11.2 m2. The drip irrigation was conducted according to the soil tensiometer indications (-0.04 MPa). The research material was the eatable parts of fresh fruits that were analyzed directly after the harvest and after the storage for six months at the temperature 10°C and the relative air humidity 75%. The drip irrigation performed during the cultivation of winter squash increased the content of vitamin C, total carotenoids including ß-carotene, as well sugars in the fruits, both after the harvest and after the storage. After six months of the storage the rise of the content of dry matter, total carotenoids including ß-carotene, as well monosaccharides was noted, while the level of vitamin C, total sugar, and saccharose have been reduced.

Opis:
W ścisłych doświadczeniach polowych, przeprowadzonych w roku 2011 na glebie bardzo lekkiej w Kruszynie Krajeńskim koło Bydgoszczy, porównywano reakcję trzech odmian sałaty rzymskiej w uprawie wiosennej i jesiennej na fertygację kroplową azotem. Doświadczenia założono jako dwuczynnikowe w czterech powtórzeniach. Badanymi czynnikami były: dawka azotu podawana w formie płynnej (25 kg N·ha-1, 50 kg N·ha- 1), odmiana uprawna (‘Barracuda’, ‘Chiquina’, ‘Romora’). Fertygację przeprowadzono przy użyciu proporcjonalnego dozownika do nawozów. Wyższy plon handlowy badanych odmian sałaty rzymskiej stwierdzono w uprawie wiosennej. Zwiększenie dawki nawożenia azotowego z 25 kg N·ha-1 do 50 kg N·ha-1 istotnie zwiększyło plon handlowy sałaty. Spośród badanych odmian ‘Romora’ wydała wyższy plon w uprawie wiosennej, natomiast w uprawie jesiennej najwyżej plonowała odmiana ‘Barracuda’. Najniżej plonowała odmiana ‘Chiquina’. W uprawie wiosennej uzyskano większą masę główki sałaty. Wyższa dawka azotu wpłynęła na istotne zwiększenie masy główki. Największą masę pojedynczej główki sałaty zanotowano u odmiany ‘Barracuda’. Wyższa dawka azotu spowodowała – przeciętnie dla trzech badanych odmian – zmniejszenie zawartości suchej masy w liściach sałaty w uprawie wiosennej, zaś w jesiennej – zwiększenie. Liście sałaty w uprawie wiosennej cechowały się wyższym poziomem azotanów od uprawianej jesienią. Wyższa dawka azotu wpływała na wzrost poziomu azotanów w liściach sałaty. Odmiana ‘Romora’ wykazała najmniejszą skłonność do kumulacji azotanów w liściach.
Field experiments were conducted in 2011 on the very light soil in Kruszyn Krajeński near Bydgoszcz. Responses of the three romaine lettuce cultivars grown in spring and autumn to nitrogen fertigation by drip system were compared. Experiments were established as two-factorial trials, four times replicated. The experimental factors were: nitrogen dose of fertigation (25 kg N·ha-1, 50 kg N·ha-1), cultivars (‘Barracuda’, ‘Chiquina’, ‘Romora’). Fertigation was conducted with the usage of proportional mixing dispenser. Higher marketable yield of romaine lettuce cultivars was noted in spring cultivation. Increased nitrogen dose (from 25 kg N·ha-1 to 50 kg N·ha-1) significantly increased marketable yield of lettuce. From among the tested cultivars, ‘Romora’ was characterized by the higher yield in spring cultivation whereas ‘Barracuda’ – in autumn. ‘Chiquina’ was characterized by the lowest yield. The higher weight of a single lettuce head was noted in spring cultivation. The higher nitrogen dose significantly increased the single lettuce head. The highest single lettuce head was noted in case of ‘Barracuda’. On average for cultivars tested, the higher nitrogen dose caused the decrease of dry matter content in leaves of lettuce grown in spring time, and in case of autumn cultivation this tendency was opposite – the higher nitrogen dose increased the DM content. Lettuce leaves in spring cultivation were characterized by the higher nitrate content as compared to those from the autumn cultivation. The higher nitrogen dose increased the nitrate content in leaves of lettuce. ‘Romora’ was characterized by the lowest tendency to accumulation of nitrates in leaves.

Opis:
This study examined the effect of fertilisation with compost prepared from hygienised sludge with an addition of pine-tree bark and mulching with fresh forest ectohumus on selected growth parameters for two - and three-year-old Scots pine trees and on the incidence of mites (Acari) in the soil. The experiment was carried out in 2009-2010 in the Białe Błota forest nursery (Bydgoszcz Forest District) on proper rusty soil. The entire area of the experiment was irrigated with a stationary sprinkler. Organic fertilisation with compost prepared from hygienised sludge with an addition of pine-tree bark resulted in a significant increase in the plant height and the diameter of the root neck in two-year-old pine trees. The effect of mulching on these parameters was not significant. The synergistic effect of the factors on the plant height and the diameter of the root neck was not significant. Organic fertilisation significantly increased the height of 3-year-old pine trees, whereas it did not have a significant effect on the root neck diameter. Mulching increased the plant height significantly, but no statistical effect on the diameter of the root neck was demonstrated. Although no significant interaction of either experimental factors in their effect on the plant height and the diameter in the root neck was observed, the parameters tended to increase in the experimental option, which included organic fertilisation and mulching. Mulching had a significant effect on the presence of soil mites, especially oribatid mites (Oribatida). Their density increased greatly after the procedure. This growth, as well as an increase in the ratio of Oribatida to Actinedida could be a sign of improvement of the biological balance of the soils under study and their biological activity.

Opis:
In the climatic conditions of Poland the temporary lack of rainfall during the vegetation season, influenced on the water deficits in the top soil level. This situation can effect on the height and quality of yields in particular years. There is estimated that in the – so called – Large Valleys Region the water deficiency ranged 200-300 mm. Production of cucurbit’s vegetables in open field is strictly connected with thermal-rainfall conditions during the vegetation season. The optimal soil moisture is the very important factor for high and good quality yield. So, the production of the cucurbit plants should be connected with the irrigation installations. The aim of the study was to determine the influence of drip irrigation in cultivation of summer squash ‘Danka’ under light soil conditions. The trials were conducted in the years 2004 – 2006 at the experimental field in Kruszyn Krajeński near Bydgoszcz – on a soil of rye weak complex. The plot area for harvest was 9,1 m2. The irrigation rates were done on the base of soil water potential according to tensiometer indications. The irrigation was started when the soil water tension was – 0,04 MPa. The fruits of the summer squash were harvested in the technological maturity in the second decade of September in each year of the study. The single weight and number of the fruits as well as marketable yield from the unit area were estimated. In the pulp the dry matter, vitamin C, sugars and carotenoids content were determineted. It was found that drip irrigation significantly increased the marketable yield of fruits. The higher yield increases were detected in the years with lower rainfalls. The significant influence of drip irrigation on the content of vitamin C and sugars was stated. The dry matter and carotenoids content were higher in the fruits from the irrigated plots, but the difference was insignificant.

The aim of the study was to determine the effect of drip irrigation on yielding of summer squash ‘White Bush’ grown under conditions of two localities: Lipnik near Stargard Szczeciński (soil of quality class IVb, and of good-rye-soil-complex) and Kruszyn Krajeński near Bydgoszcz (soil of quality class V, and of weak-rye-soil-complex). The study was designed as one-factorial trial: drip irrigation as the experimental factor was considered. Drip irrigation was conducted according to soil tensiometer indications (-0.04 MPa). Both, in Lipnik as well as in Kruszyn Krajeński, drip irrigation significantly increased marketable yield of summer squash ‘White Bush’. A higher rise in yields due to irrigation was obtained in Kruszyn Krajeński than in Lipnik. Mean marketable yield of summer squash fruits in Lipnik was higher than that obtained in Kruszyn Krajeński. Drip irrigation significantly increased the single fruit weight in relation to the control, in both crop localities. The system of drip irrigation significantly affected the number of fruits per plant. Summer squash plants grown in Lipnik produced higher number of fruits, than in Kruszyn Krajeński. In addition, essential influence of drip irrigation was affirmed on chemical composition of fruits, i.e. dry matter, vitamin C, monosaccharides, saccharose, content of total sugars and sum of carotenoids and ß-carotin.
