Opis:
In the years 2005–2007, research work on the influence of surface and subsurface drip irrigation on the yield and quality of roots of parsley grown on ridges and on flat ground was carried out. Irrigation water was supplied via drip lines, which in subsurface irrigation were placed at a depth of 50 mm below the surface of the ridges, along the centreline between two rows of plants. In the case of surface irrigation, the drip lines were placed on the surface of the ridges between two rows of plants. Irrigation started when soil water potential was between -30 and -40 kPa. Nitrogen fertilizers (100 kg⋅ha-1) were applied in two doses. The first dose was applied pre-plant, while the second one was delivered by fertigation. In the control treatment without irrigation, the second dose of nitrogen was applied by broadcasting. Both surface and subsurface irrigation used in the cultivation on ridges and on flat ground had a significant effect on the marketable yield of parsley roots. However, no significant differences in the yield between surface and subsurface drip irrigation were found. The yield of non-marketable parsley roots in flat cultivation was twice as high as that in ridge cultivation. Parsley plants cultivated on ridges produced significantly longer, better-shaped storage roots compared to those cultivated on flat ground. Surface and subsurface drip irrigation significantly decreased the total N and K content in parsley roots.
W latach 2005–2007 badano wpływ nawadniania kroplowego powierzchniowego i podpowierzchniowego na plonowanie korzeni pietruszki uprawianej na płaskim gruncie i na redlinach. Nawadnianie prowadzono z użyciem przewodów nawadniających, z wewnętrznie wtopionymi co 35 cm emiterami z kompensacją ciśnienia, które przy nawadnianiu podpowierzchniowym umieszczono na głębokości 50 mm, pośrodku dwóch rzędów roślin. Nawadnianie rozpoczynano, gdy potencjał wodny gleby wynosił od -30 kPa do -40 kPa. Nawozy azotowe (100 kg N⋅ha-1) wprowadzano w dwóch dawkach: pierwszą zastosowano przedwegetacyjnie, drugą podano przez fertygację. W kontroli drugą dawkę wniesiono w nawożeniu posypowym. Nawadnianie kroplowe powierzchniowe i podpowierzchniowe zastosowane zarówno na redlinach, jak i na płaskim gruncie powodowało istotny wzrost plonu handlowego korzeni pietruszki. Natomiast nie stwierdzono różnic w plonie pietruszki po zastosowaniu powierzchniowego i podpowierzchniowego sposobu nawadniania kroplowego. W uprawie pietruszki na redlinach udział korzeni niekształtnych w plonie był o 100% mniejszy w porównaniu z uprawą na płaskim gruncie. Pietruszka uprawiana na redlinach wytwarzała dłuższe korzenie spichrzowe, o lepszym kształcie w porównaniu z uprawą na płaskim gruncie. Nawadnianie powierzchniowe i wgłębne powodowało istotny spadek zawartości azotu ogólnego i potasu w korzeniach pietruszki.

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.

Opis:
High yields with low costs require that sugar beets be kept free of weeds, during critical periods, using labor or chemical treatments. Since the critical periods for this crop in Castilla – La Mancha (Spain) are unknown, the first goal of this study was to determine the effect of early and late competition on yield. The second goal was to determine the critical periods, while taking into consideration the semiarid climatic conditions of this region. Two irrigation farms located in the province of Albacete are dedicated to sugar beet cultivation. These two farms were chosen to carry out the tests March (140,000–150,000 seeds ∙ ha–1) and harvested in October. Two simultaneous and complementary experiments were carried out in each year and farm. Two scenarios were considered with eight different treatments each. In the first one (With Weeds Until – WWU), plots were infested by weeds up to a certain date. In the second one (Free of Weeds Until – FWU), plots were kept free of weeds up to a certain date. For each test, a randomised experimental blocked field was designed and there were four repetitions, each of them containing eight elemental plots (12 m2). Each plot was weeded by hand or weeds were left to grow till a definite date.The results indicated that a 1% loss of yield was reached in the early competition after 14 days, while a loss of 5% was reached after a period of 41 days after it was infested. The results also indicated that in late competition, if a crop is kept clean for 124 days and it is infested afterwards, a 1% loss is reached. However, the loss increases to 5% if the plot is kept clean for 111 days. For a 1% loss the critical period is 110 days and 70 days for a 5% loss.

Opis:
One of the ways to reduce the water consumption by plants while maintaining their proper quality is to use substances that limit excessive transpiration. Three preparations at following concentrations: Moisturin (10%), Root-Zone (4.5%) and Vapor Gard (1%), were used in the experiment. Moisturin and Vapor Gard were applied in the form of a single spray, and Root-Zone as a single irrigation in mid July.The aim of the research was to assess the effect of several anti-transpirants on some biometric features of the ‘Tardiva’ panicled hydrangea depending on the frequency of irrigation. The following parameters were measured: area, perimeter, width and length of leaf blade, length and width of inflorescences, and the diameter of shoots. Treatment of H. paniculata cv. ‘Tardiva’ with Root-Zone and Moisturin anti-transpirants with a single irrigation every other day allows to reduce the water consumption and obtain shrubs of a quality comparable with plants irrigated twice a day. The use of Moisturin with a twice daily irrigation positively affected the length and width of inflorescences.

The study was carried out in order to determine the frequency of droughts in the period of increased water needs in potato, and to assess the needs and expected productive effects of the plants grown under irrigation on the basis of temporal variation of the standardized precipitation index SPI in the Kujawsko- Pomorskie district. Rainfall data were derived from standard measurements of atmospheric precipitation in between 1 July and 31 August in the multi-annual period 1981-2010.These data were obtained from the branches of COBORU in Chrząstowo, Głębokie and Głodowo, and the University of Technology and Life Sciences Research Centre in Mochełek. The results of carried research showed that the frequency of occurrence of dry spell during the period of increased needs for water of potato amounted to 26.7-40.0% in the region, depending on the locality. Strong droughts occurred in the year 1983, 1989, 1992 and 1994, moderate drought in 2005 and weak droughts in 1982, 1984 and 1999. Great irrigation needs of potato which corresponded to periods of strong and moderate droughts (SPI ≤ - 1.0) have been identified in 5 years of the 30 years examined. The expected increase in the yield of potato tubers grown on light soils under irrigation during those years exceeded 15.7t.ha-1. In the 9 years of the 30 have occurred mediumlevel irrigation needs, which in the period of July-August, corresponded to SPI values between 0 and -1.0.

Opis:
W badaniach podjęto próbę porównania wybranych właściwości fizycznych bulw ziemniaków. Badania przeprowadzono na bulwach dwóch odmian ziemniaków tj. Lady Claire i Saturna uprawianych na plantacji nawadnianej i nienawadnianej. W badaniach laboratoryjnych wykorzystano metodę video-komputerową pozwalającą określić parametry geometryczne i wyliczyć współczynniki sferyczności. Zaobserwowano statystycznie istotne różnice pomiędzy wartościami średnimi współczynników sferyczności bulw ziemniaków uprawianych na plantacji nawadnianej i nienawadnianej. Stwierdzono że deszczowanie plantacji wpłynęło na zmniejszenie wartości współczynnika wydłużenia bulw i zwiększenie wartości współczynnika spłaszczenia bulw. Bulwy z plantacji deszczowanej były zbliżone do kształtu kulisto-owalnego.
In the research an attempt of comparing physical parameters of potatoe tubers diversified in terms of the technology, cultivation and variety was made. Research were carried out on two variants of potatoes tubers i.e. of Lady Claire and the Saturna planted on the irrigated and not-irrigated field. In laboratory testing a video-computer method was used – letting determine geometrical parameters and enumerate rates of form factor. Statistically significant differences were observed between medium value of friction coefficient of potatoe tubers planted on the irrigated and not-irrigated field. Sprinkling of the plantation had an effect on reducing the elongation rates and increasing flattening rates of the tubers. Tubers from the sprinkled field are in the greater degree similar to the spherical-oval shape, hence the joint surface with the rubbing base is smaller, and the pressure of tubers to this surface is bigger.

Water is the most important environmental factor in growth and fruit yield of trees. To study the effect of deficit irrigation on reproductive characteristics and yield of seven superior olive genotypes of D1, Dd1, Gw, Ps1, Bn3, Bn6, and Ds17. The present research was accomplished in Dallaho Olive Research Station of Sarpol-e zahab, Kermanshah, Iran, in 2014 and 2015. Seven superior olive genotypes were studied in a randomized complete block design with three replicates and three irrigation regimes. The irrigation treatments included: 100% full irrigation (control), 75% deficit irrigation, and 50% deficit irrigation applied during the growth season. The results indicated that the genotypes had different reactions to the deficit irrigation regimes. Dd1 had the highest fruit weight, while the lowest fruit weight was observed in Ps1 and Gw. The highest fruit yield was found in Bn3, Bn6, and Dd1, while the lowest was observed in Ps1. As a result, Bn6 and Dd1 are introduced as the genotypes that are resistant to drought in the field.

Opis:
Testing the globally popular grapevine rootstocks for affinity with new grape cultivars or tolerance potential to stress factors like drought is essential for districts where supplemental irrigation is more frequently needed due to the pressures of a global climate change. In this study, a seasonal evaluation of leaf gas exchange, leaf temperature, leaf greenness (chlorophyll content prediction) and vegetative development of Vitis vinifera L. cv. ‘Prima’ grafted to different rootstock genotypes having great variability in drought tolerance, were investigated. The experiment was conducted in a controlled experimental glasshouse on two-year-old soilless grown ‘Prima’ vines grafted on nine rootstocks [44-53 M, 5 BB, 140 Ru, Ramsey (Syn. Salt Creek), 99 R, Saint George (Syn. Rupestris du Lot), 41 B, 1613 C and 420 A]. A long-term deficit irrigation (DI) was imposed before bud break by reducing water supply to 40% of field capacity derived from concurrent measurements of water content of growth medium and maintained until the end of vegetation period. The rootstocks significantly modulated the physiology and vegetative growth of the scion cultivar in varying degrees according to their genetic features. Among them, 140 Ru rootstock found to be more prominent in terms of mitigating the adverse effect of water deficit on physiology and growth of the scion genotype ‘Prima’ as there were no significant difference between deficit and full irrigation treatments for most of parameters investigated. In general, the ‘Prima’ scion performed better when the rootstocks coming from V. berlandieri × V. rupestris pedigree rather than the others including V. berlendieri × V. riparia.

Opis:
Cucumber is one of the most popular vegetables in Poland. This vegetable species is characterised by high requirements in terms of soil temperature and moisture. The utilization of polyethylene mulch in combination with drip irrigation has played a major role in the increases in production of cucumber. The benefits associated with the use of this cultivation method include earlier and higher yields, reduced soil evaporation, reduced weed populations, reduced fertilizer leaching, greater water use efficiency, reduced soil compaction, control of certain pests, and cleaner harvested product. In years 2002, 2003 and 2005 experiments were conducted to study the impact of soil mulching with black polyethylene on Akord F1 cucumber yields. Plants were cultivated on sandy loam soil using irrigation and fertigation applied with the assistance of drip lines. No significant differences were observed in levels of total and marketable yields of fruits as well as in dry matter and total carbohydrate contents in fruits obtained from plants cultivated in mulched and unmulched soils. Irrigation efficiency, on the soil mulched with black polyethylene was higher than on the soil without mulching.
Ogórek jest jednym z najbardziej popularnych warzyw w Polsce. Gatunek ten charakteryzuje się między innymi wysokimi wymaganiami w stosunku do temperatury i wilgotności gleby. Ściółkowanie gleby w połączeniu z nawadnianiem kroplowym może być dobrym rozwiązaniem dla spełnienia tych wymagań. Korzyści wynikające z takiego sposobu uprawy to: wcześniejszy i większy plon, zmniejszone parowanie gleby i wymywanie składników pokarmowych, a co za tym idzie – większa efektywność nawadniania i nawożenia, mniej chwastów na plantacji, mniejsze zbicie gleby, możliwość zmniejszenia stosowania pestycydów i czystsze produkty. W latach 2002, 2003 i 2005 przeprowadzono badania dotyczące wpływu ściółkowania gleby czarną folią polietylenową na plonowanie ogórka gruntowego odmiany Akord F1. Rośliny były uprawiane na glebie piaszczysto-gliniastej, z zastosowaniem nawadniania i fertygacji, prowadzonych przy użyciu linii kroplujących. Nie stwierdzono istotnych różnic w wielkości plonu ogólnego i handlowego owoców oraz zawartości suchej masy i cukrów w owocach z roślin uprawianych na glebie ściółkowanej i bez ściółki. Efektywność nawadniania na glebie ściółkowanej czarną folią była większa niż na glebie nieściółkowanej.

Opis:
Sweet basil (Ocimum basilicum L.) is an annual plant belonging to the plant family Lamiaceae. There are many varieties of basil, with leaves of colour from green to purple and with small white or pink flower. In field experiment conducted in the years 2007–2008 there was investigated the effect of nitrogen fertilization in the doses of 50, 150 and 250 kg N·ha-1and irrigation on yielding and nutritional status of basil of ‘Red Rubin’ cultivar grown from transplants. Basil positively responded to irrigation and the increase in its yield under the influence of irrigation amounted from 97.37% to 25.36% in subsequent years of cultivation. Also the dose of nitrogen did advantageously affect basil herb yield. The highest yields were recorded at the dose of 150–250 kg N·ha-1. The highest amount of nitrates ranged from 697.00 to 938.00 mg·kg-1 f.m. was determined in plants fertilized with nitrogen dose of 250 kg N·ha-1. The level of macroelements depended both on irrigation and on nitrogen doses. Irrigation caused decreased amounts of phosphorus, potassium and calcium, while content of magnesium increased. The highest quantities of phosphorus and magnesium were obtained at nitrogen dose of 150 kg N·ha-1, while for the highest values of potassium and calcium nitrogen dose was 250 kg N·ha-1.
Bazylia pospolita jest rośliną jednoroczną należącą do rodziny jasnotowatych (Lamiaceae). Istnieje wiele odmian bazylii, które charakteryzują się różnym zabarwieniem liści (zielone, fioletowe) i kwiatów (białe, różowe) W doświadczeniu przeprowadzonym w latach 2007–2008 badano wpływ nawożenia azotem, w dawkach 50, 150 i 250 kg N·ha-1 oraz nawadniania na plonowanie i stan odżywienia bazylii o czerwonych liściach uprawianej z rozsady. Bazylia dodatnio reagowała na nawadnianie, zwyżka plonu pod wpływem nawadniania wynosiła od 97.37% do 25.36% w kolejnych latach uprawy. Również dawka azotu wpływała korzystnie na plon ziela bazylii. Największy plon odnotowano przy dawce 150–250 kg N·ha-1. Największą ilość azotanów odnotowano u roślin nawożonych dawką 250 kg N·ha-1. Ich zawartość wahała się od 697do 938 mg·kg-1 ś.m. Poziom makroelementów zależał zarówno od nawadniania, jak i dawek azotu. Nawadnianie powodowało zmniejszenie ilości fosforu, potasu i wapnia, natomiast zwiększenie zawartości magnezu. Największe wartości fosforu i magnezu uzyskano przy dawce 150 kg N·ha-1, natomiast potasu i wapnia przy dawce 250 kg N·ha-1.

Opis:
Landscape plantations are significantly water demanding in many parts of the world, particularly in dry regions. Adequate water supply is the main limiting factor behind landscape development, maintenance and beauty in such environments. On the other hand, monitoring the growth response of ornamental and landscape plants to irrigation water containing heavy metals can be useful in management and application of municipal wastewaters to these plantations instead of application in edible vegetable crops production, which is common in many urban areas. In the present study, one year old seedlings of Judas tree (Cercis siliquastrum) were irrigated for two years with water containing 0, 15 or 30 mg L–1 of lead (Pb) in absence or presence of cadmium (0 or 5 mg L–1) in a factorial design, and under greenhouse conditions. Heavy metal treatments had no significant effect on leaf SPAD value; however, plants treated with Pb15Cd0 combination had significantly higher SPAD value than Pb30Cd5 combination that showed the lowest leaf SPAD value. Increasing the lead and cadmium levels of irrigation water increased the number of chlorotic and necrotic leaves of plant than control, whereas it reduced the average leaf area and new shoot growth. The control plants or plants treated with lower level of heavy metals showed the highest leaf area and new shoot growth. Leaf photosynthesis rate was significantly reduced in all heavy metal treated plants than control plants, as the lowest amount was in Pb30Cd5 combination treatment. All heavy metal treatments showed higher leaf soluble carbohydrates and proline content than in control plants. Leaf soluble carbohydrates were highest in Pb30Cd0 and Pb30Cd5 treatments, and leaf proline was highest in Pb30Cd5 and Pb15Cd5 treatments. The results indicate that Judas tree is a relatively tolerant species to high concentrations of Pb and Cd in root medium added through the irrigation water, and long term dual application of these heavy metals can have additive harmful effects on plant growth.

Opis:
Fruit production should be adapted to future scenarios that are frequently associated with scarce resources, especially freshwater and fertilizers. New biologically-based fruit production strategies, i.e. taking into account tree growth and water status, are required to optimize irrigation and fertilization under abiotic stress conditions. It was hypothesized that a moderate abiotic stress, here deficit irrigation with or without nitrogen deficit, in the preharvest period, could decrease postharvest losses due to diseases and pruning weights due to reduced vegetative growth, without sacrificing the yield and fruit quality. This study was conducted over two years using the same trees of ‘Moncante’ nectarine cultivar grown in a commercial orchard. Trees were assigned to three treatments: (1) full irrigation at 80% estimated crop evapotranspiration (ETc), (2) deficit irrigation, i.e. at 75% of full irrigation, and (3) deficit irrigation and deficit nitrogen, i.e. at 75% of full irrigation and 75% of usual N-fertilization adopted by the grower in this commercial orchard. Deficit irrigation alone and in combination with deficit nitrogen reduced postharvest diseases and pruning weights without significant yield losses. Our results suggest that ETc-based approaches of reduced water irrigation may be a sustainable way to decrease phytosanitary inputs and workload in the orchard while maintaining the orchard performance.
