In the field experiment, 5-year-old 'Morden 604' and 'Miodowa' apricot trees grafted on the seedling rootstocks Wangenheim Prune and Erunosid (both P. domestica L.), as well as Polish selection apricot (P. armeniaca L.) genotypes A4 and M46 were compared with trees of the same cultivars on the standard P. divaricata rootstock. Vigour in apricot trees was affected by rootstock type. Trees of both...
The subjects of this study were 8-year-old sweet cherry trees of the cultivar 'Kordia' grafted on the 'Colt' rootstock. The trees had been trained as spindles for four years after planting. In the fifth year, four systems of pruning were introduced: 1) the spindle form - i.e. the pruning system remained unchanged, 2) Zahn's method of pruning, 3) one-year-old shoots were cut back leaving approximately...
The paper is based on the chosen results of two one-year field experiments which were conducted in the vicinity of Bydgoszcz (Poland) and in the vicinity of Cukurova (Turkey). The aim of the study is to present the comparison of yields of chosen watermelon cultivars grown in the different climatic-soil conditions under drip irrigation with N fertigation. The experiment in Turkey was carried out under...
Intensified production of apples makes a fruit grower establish an orchard immediately after grubbing up an old one. Then, if replanting does not occur, stands for new trees can be significantly affected by soil properties conditioned by a long- term way of its management. Another problem in horticulture is water deficit. Due to diminishing water reserves there is a need to improve sorption capacity...
In the paper the influence of daily milk yield in peak lactation, milk yield during 305 days after calving and number of cows’ calving on frequency of lactations longer than 305-day standard were analyzed. It was also estimated the influence of extended lactation on milk yield and milk composition. The research were carried out in a herd including 220 Polish Holstein-Friesian cows of Black-And-White...
A field experiment was conducted in the period 2006- 2008 in the Uhrusk Experimental Farm belonging to the University of Life Sciences in Lublin. The experimental factor was the type of stubble crop ploughed in each year after harvest of spring barley: white mustard, lacy phacelia, winter rape, and a mixture of narrow-leaf lupin with field pea. In the experiment, successive spring barley crops were...
The aim of this study was to determine the effect of mixed multi-component fertilizers on spring wheat yield, the content and uptake of macronutrients. A three-year field experiment (2005–2007) was carried out in a randomized block design at the Research and Experimental Station in Tomaszkowo, at the University of Warmia and Mazury in Olsztyn. The experiment comprised three fertilization treatments...
The aim of our research was to determine the potential of waste generated during the production of chlorine for the synthesis of polyvinyl chloride as plant fertilizer in agriculture. For the production of fertilizer sludge produced when cleaning the saline solution, 78 vol % waste sulphuric acid from the dehydration of chlorine and calcinated magnesite were used. The product contains minimum: MgO...
The present study, carried out in the period 2007-2009 in the Sandomierz Upland, did not show a significant effect of foliar fertilization on trunk thickness and canopy volume in the cultivar Łutówka. However, under the influence of urea applied three times in combination with Florovit at a concentration of 0.5%, a clear increasing trend was observed in the above mentioned parameters used to assess...
