Opis:: The impact of regulated drip-irrigation on productivity and fruit quality of tomato ‘Tofane’ has been studied under a warm dry desert climate in southern Algeria. Yield, fruit weight and size, water content and parameters of fruit quality – total soluble solids, phenolic compounds, carotenoids, vitamin C, pH and titratable acidity were determined. Two irrigation treatments were applied in 2012 and 2013: T1, optimal irrigation (100% evapotranspiration – ETc) during the whole growth period (growth stages I, II and III); T2, optimal irrigation during I and II stages, and regulated deficit irrigation (67% ETc) during stage III (from fruit set to full fruit maturity of first and second bunch). T1 treatment during the whole season showed the highest values of soil water potential (Ψsoil), between −0.02 MPa and −0.06 MPa, on depths of 0.3 and 0.6 m, respectively. During stage III, regulated deficit irrigation caused the lowest Ψsoil values, which were between −0.1 MPa and −0.12 MPa on a soil depth of 0.3 and 0.6 m, respectively. Deficit irrigation caused significant decrease of water content in fruits and not significant decrease of fruit weight and size, as well as fruit yield while water saving for irrigation amounted to 10%. Comfort-irrigated tomato plants produced fruits containing significantly higher titratable acidity, total soluble solids and vit. C content. There was a tendency to decrease carotenoid content and increase phenolic content in both years of the study. Due to the possibility of water saving with not significant yield decrease, it seems that the reduction of water use in growth stage III would be an adequate strategy for tomato cultivation in hot, dry climate.

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:: 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.
