In the years of 2003–2005 two-factors field experiment was set up in ES Lipnik near Stargard Szczeciński on the sandy soil (good rye complex) and a small retencion of usefulness water. The aim of the study was to determine the ef-fect of irrigation and mineral fertilization on the photosynthetic activity the leaves of some species of stone fruit trees. All experiments were done on the trees 4 years after planting. The experiments were designer by split-plot method in 7 replications with cherry, 5 replications with peach, and 4 replications with plum. Among the trees was the lawn but in the rows the selective herbicide fallow was kept. Two factors were considered: irrigation (O – control, W –under – crown ir-rigation) and mineral fertilization for cherry and plum 0 NPK – control (without fertilization), 1 NPK – 130 kg NPK•ha-1, 2 NPK – 260 kg NPK•ha-1; and for peach 0 NPK – control (without fertilization), 1 NPK – 150 kg NPK•ha-1, 2 NPK – 300 kg NPK•ha-1. Measurements of cherry, peach and plum leaves photosynthesis were done on well developer leaves on one year old branches. On basic of obtained results was found that photosynthetic activity of cherry peach and ...
Field experiment was carried out in the years 2003–2006 in ES in Lipnik near stargard (Szczecin region) on sandy soil belong to god-rye-complex. The experiment was set up by split-plot method in seven repetitions. Between the trees there was sward and in the rows the herbicidal farrows there kept. The aim of the studies was to determine the effect of under crown irrigation and mineral fer-tilization on the yield of plums cv. ‘Amersis’ and ‘Cacańska Rana’. The first fac-tor of the study was supplemental irrigation (0-control without irrigation: W- under crown irrigation). The second factor was different level of mineral fertiliz-ing: 0NPK, 1NPK – 130kg . NPK. ha-1 (40+30+60), 2NPK - 260kg . NPK. ha-1 (80+60+120). Supplemental irrigation was used when the tensiometer have shown that water potential of soil dropped lower than 0,01 MPa. For irrigation the ‘Hadar’ sprinkler were used (r=2m). Depending on rainfall the amount of ir-rigation from 21,0 to 37,9 mm there used. As effect of irrigation the yields in-creased by 19,2%. The highest increased (36,1%) was obtained in 2006 and the lowest (8,2%) in 2005. To evaluation the effects of mineral fertilizers the highest crops obtained from the plots fertilized with 2NPK ...
Field studies conducted in the years 2003 - 2005 in the Agricultural Experimental Station in Lipnik near Stargard, on sandy soil. The aim of this study was to determine the effect of irrigation and fertilization crown on the content of total chlorophyll and carotenoids in leaves of cherry, peach and plum trees. Irri-gation was applied in the form of crown, in which water was distributed by type sprinkler Hadar, where the soil water potential fell below -0.01 MPa. Nitrogen fertilizers applied in early spring, before moving the vegetation, while phosphorus and potassium in the autumn according to the agricultural. All experiments were randomized block design established in the system dependent (called a split-plot), in seven replications in the experiment with cherry, peach and five with four repli-cations in the experiment with the plums. All experiments were carried out on trees in the fourth year after planting, fall within the third year of fruiting. Trees were planted at spacing: cherry - 4 x 2 m, peach - 3.5 x 3 m, plum - 4.5 x 4 m. per hec-tare were 1,250 pieces of cherry trees, peach trees 952.4 pc and 555, 5 pieces of plum trees. Maintained grass between the trees, ...
A field experiment was conducted in 2003 and 2005 at the Experimental Station Lipnik near Stargard, on acid brown soil. The soil is classified as quality class IVb, good rye complex, and for cultivation of light soils with low water re-tention useful. We evaluated the use of water for cherry grown under different water and fertilizer. The experiment was randomized block design in the system dependent (called a split-plot), in seven replications in the experiment. The research was conducted on trees in the fourth year after planting, fall within the third year of fruiting. Maintained grass between the trees, and rows of trees - herbicide fallow. The factor I was watering under-crown: O-control (without irrigation), W-irrigated sites, where soil water potential fell below 0.01 MPa. Irrigation system was used under-crown in which water was distributed by type of Hadar sprinkler scale spraying for cherry-1m. Second factor was the mineral fertilization NPK 0 - control (without fertilization), 2 NPK - 260 kg NPK. ha-1 (80 +60 +120). Nitrogen fertilizers applied in early spring, before moving the vegetation, while phosphorus and potassium in the autumn according to the agrotechnical. Based on water intensity ratio of photosynthesis to transpiration and photosynthetic rate were ...
A field experiment was conducted in 2003-2005 at the Experimental Station Lipnik near Stargard, where they were founded three two-factor experiment. The research was conducted on an acid brown soil. The soil is classified as quality class IVb, good rye complex, and for cultivation of light soils with low water retention useful. In each of the experiments were evaluated: the impact of different irrigation and fertilization on bulk density and soil water stocks. All experiments were randomized block design established in the system dependent (called a split-plot), in seven replications in the experiment with cherry, five replications with peach and four replications in the experiment with the plums. Were carried out on trees in the fourth year after planting, fall within the third year of fruiting. Maintained grass between the trees, and rows of trees - herbicide fallow. Order factor was irrigation under-crown: O-control (without irrigation), W-objects irrigated when soil water potential fell below 0.01 MPa. Irrigation system was used in which water was distributed by type of Hadar scale spraying for cherry r-1m , peach r-1,5m, and plum r-2m. The dosages of water under the tree stone in different growing seasons ranged from 21.7 to 61.3 mm depending on ...
The second part of paper presents effects of supplemental irrigation and mineral fertilization on pH soil and content of selected macroelements. Both used agrotechnical diversified mineral content in the soil, contributing to changes in soil fertility. Applied irrigation allowed the movement of minerals in the soil profile, high mineral fertilization increased their concentration in the investigated soil layers. Both irrigation and fertilization effect on pH changes in the KCL and the content of mineral forms of nitrogen.

The paper presents the results obtained from field experiments conducted in 2002-2003. They evaluated the effect of irrigation and fertilizationof cherry on the yield and mineral content of some macro-and micronutrients in the soil.Years in which the study was conducted were varied in terms of rainfall-thermal conditions. The growing season in 2002 was characterized by a moderate amount of precipitation and air temperature,while the year2003 was clearly dry and warm. In the study of fruit crops increased under the influence of irrigation, an average of 2.5 kg in terms of a single tree. Similarly, applied fertilizer increased yields of cherries, but the biggest influence was spreading at 1NPK. Under the influence of a higher dose 2NPK fertilization, fruit yield has not increased. Agrotechnical used modified the soil chemcal properties. The most affected was N in the layer of topsoil and under. ...
