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:
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:
The nutritive compounds of the onion are influenced by genetic as well environmental factors. Due to its shallow poorly-developed root system, onion has a low potential of using nutrients from soil. Usually mineral fertilisation increasing the yield and change the chemical composition in vegetables, and it is the chemical composition which determines the nutritive value of onion. Over 2003–2006 at Korytowo, about 30 km away from Bydgoszcz, northwards, 2-factor field experiments were set up in ‘split-plot’, in three reps. The aim of the study has been to determine the effect of the nitrogen rate (0, 60, 120, 180 kg N·ha–1) on the content of dry matter, vitamin C and monosaccharides and total sugar in onion of two cultivars: Kutnowska and Efekt. Increasing nitrogen fertilisation has resulted in a decrease in the content of dry matter in the bulbs of the onions under study. The ‘Kutnowska’ showed a higher content of total sugar and, at the same time, a lower content of monosaccharides than ‘Efekt’. ‘Efekt’ reacted with an increase in the content of vitamin C and monosaccharides as affected by higher fertilisation rates. A different reaction was noted in ‘Kutnowska’. The lower the dry matter content in onion bulbs – the greater content of total sugars and less content of monosaccharides.

Opis:
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.
