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 the strength of growth. In years of abundant fruiting, this study showed a significant increase, or on the verge of significance, in yield after threefold application of urea and Florovit in combination. A small insignificant effect of fertilization on fruit weight shows that the growth in yield after the application of fertilization was produced as a consequential effect of a significant increase in the length of one-year shoots and thereby in flowering intensity of the 'Łutówka' cherry trees. In the case of the sour cherry cultivar Łutówka bearing fruit on one-year shoots, foliar feeding after flowering using multi-nutrient fertilizers and urea can be recommended as a technological treatment, in particular in years of abundant fruiting.

In no examined years of the studies were found no significant differences of flowering intensity between the ownoroots trees of the cultivar Łutówka and trees budded on <i>Prunus mahaleb</i>. The kind of trees clearly, but not significantly, affected fruit mass. The growth of the ownroot "in vitro" trees were significantly less than the trees budded on <i>Prunus mahaleb</i> seedling. Fruit set and yielding of the own root trees were higher, but only in one year of study significantly higher.

The effect of rootstock on the flowering and fruiting response of sweet cherries (Prunus avium L.) was investigated using 4-year-old branch units. The cherry rootstock Edabriz (Prunus cerasus L.) affected the flowering and fruiting response of `Burlat' sweet cherry compared to Maxma 14 and F12/1. Branches of trees on Edabriz had more flowers, more flowers per spur, more spurs, more fruit, higher yields, smaller fruit, and a reduced fruit set compared to the standard rootstock, F12/1. One-year-old branch sections had more flowers and fruit, higher fruit weight, and heavier fruit size compared to older branch portions.

Sludge Application

This study describes the long-term effects of different sewage sludge application rates on vegetative parameters, morphological characteristics, yield, and chemical properties of fruit and leaves of sour cherry (Prunus cerasusL.) cv. “Kütahya.” A three-year field experiment was set up in a completely randomized block design with six sewage sludge application rates (0.0, 2.5, 5.0, 7.5, 10.0 and 12.5 kg of dry matter per tree) and three replications. One-year-old Kütahya sour cherry trees grafted onPrunus mahalebrootstock were evaluated. In all application rates, sewage sludge altered vegetative growth parameters, morphological characteristics, and yield. The most effective application rate was 7.5 kg per tree, it increased cumulative yield more than twofold. The results obtained in this study demonstrate that application of sewage sludge to light-textured soil is an effective means for improvement of vegetative growth and yield, and that a single application of sewage sludge sustains its effects for at least 7 years.

The effects of municipal solid waste (MSW) materials on growth, yield, and mineral element concentrations in tomato (Lycopersicon esculentum Mill.) (1991 and 1992) and squash (Cucurbita maxima Duch. Ex Lam.) (1992 and 1993) were evaluated. Agrisoil compost (composted trash), Eweson compost (co-composted trash and sewage sludge), or Daorganite sludge (chemically and heat-treated sewage sludge) were incorporated into calcareous limestone soil of southern Florida. The control had no MSW material added to the soil. The effect of MSW on crop growth, yield, and mineral element concentrations varied considerably between years for tomato and squash. In 1991, tomato plants grown in soil amended with Eweson or Daorganite had a greater canopy volume than plants in the control treatment. Tomato plants grown in Daorganite had greater total fruit weight (1991) than plants in Agrisoil and more marketable fruit (1992) than control plants. In both years, tomato plants in Agrisoil had higher root Zn concentrations than plants in the other treatments. In 1992, tomato plants in Eweson had lower root Mn concentrations than plants in the other treatments, whereas Mg concentrations in the roots were higher in the Daorganite treatment than in Eweson. Tomato plants in Agrisoil had higher Pb concentrations in the roots than plants in all other treatments. In 1991, leaves of tomato plants in Agrisoil had lower Ca concentrations than leaves of plants in the control treatment. In 1992, leaf Zn concentrations were greater for tomato and squash in Agrisoil than in the control or Daorganite. In 1992, canopy volume and yield of squash were greater for plants in Daorganite than for plants in the control and other MSW treatments. Although canopy volume and total squash fruit weight did not differ among treatments in 1993, plant height was greater for squash plants in the MSW treatments than for those in the control. In 1993, leaf Mg concentrations were greater for squash grown in Daorganite than for plants in the control or Agrisoil. In 1993, fruit Cd concentration was higher for plants with Eweson than for plants in the control or Agrisoil. However, the fruit Cd concentration in squash grown in Eweson compost (1.0 mg/kg dry weight) was far below a hazardous level for human consumption. Our results indicate that amending calcareous soils with MSW materials can increase growth and yield of tomato and squash with negligible increases in heavy metal concentrations in fruit.

At Fruit Research Institute in Cacak, major objectives of the work on breeding new sour cherry (Prunus cerasus L.) cultivars are high cropping, large, high-quality fruits and resistance to causal agents of diseases and pests. As a result of the planned hybridization, more than 10,000 hybrid seedlings have been developed from about 40 cultivars within more than 110 parental combinations, among which are 'Cacanski rubin' ('Shasse Morello' x 'K?r?ser Weichsel') and 'Sumadinka' ('K?r?ser Weichsel' x 'Heimanns Konserven Weichsel') which have been named and released. Ten-year study of 11 hybrids, selected from the population of about 3,000 hybrid seedlings, gave four hybrids which have been singled out as elite (III/23, III/31, II/40 i XII/57). These hybrids are currently under procedure of being released as new cultivars. The paper presents two-year results of the study of ripening time, pomological properties, biochemical composition of fruits, and field resistance to causal agents of diseases and pests attacking the above named genotypes which were compared to standard cultivar 'Heimanns Konserven Weichsel'. In the studied hybrids, fruit weight, soluble solids content and sugars content were higher than in standard cultivar. In addition, they exhibit substantial field resistance to causal agents of brown rot (Monilinia laxa /Ader et Ruhl./ Honey ex Whetz.), cherry leaf spot (Blumeriella jaapii (Rehm.) v. Arx.), shot-hole (Clasterosporium carpophilum (L?v.) Aderh.) and cherry fruit fly (Rhagoletis cerasi L.) attack.

AbstractThe study was conducted in 2001–2012 next to Wrocław (southwestern Poland). The purpose of this research was to assess the influence of type of nursery trees of pear cvs ‘Carola’ and ‘Dicolor’ budded on quince S1rootstock on growth and cropping, as well as fruit quality of two pear cultivars. The trees were planted in the spring of 2001 in 4 replications with 5 trees per plot. Trees were planted in rows with spacing 1.2 × 3.5 m (2381 trees per hectare). Three types of nursery trees, all without feathers, were planted: two-year-old (3 years in a nursery), one-year-old maidens (2 years in a nursery) and annual grafts (only 1 year in a nursery). Tree canopies were formed as a spindle and were trained in the Güttingen-V system. Until the twelfth year after planting, growth and yield were significantly affected by the type of nursery trees. One-year-old maidens were characterized by the strongest vigor in orchard, while pears planted as two-year-old trees grew rather weak (especially with ‘Dicolor’ cv.). Planting two-year-old trees didn’t have any clear positive influence on tree cropping in the orchard. The final results of the study proved that trees planted as annual grafts, irrespective of cultivar, yielded significantly worse. The type of nursery trees had no clear influence on mean fruit weight.

Avocado (Persea americana Mill. cv. Simmonds) is an important fruit among consumers in Puerto Rico and in the Hispanic community in the United States. During the last years, orchard establishment has increased considerably in Puerto Rico, where production of this fruit is third behind mango and oranges. Currently growers need to deal with lack of information on proper irrigation management in orchards under conditions observed in Puerto Rico. Typically, growers are encouraged to adopt an irrigation scheduling method to ensure tree establishment and adequate productivity, and thus to reduce problems associated with improper irrigation management. The Universities of Puerto Rico and Florida recommend the use of tensiometers to schedule irrigation for fruit trees. An avocado orchard was established during 2001 for evaluating the effect of soil water tension measured by tensiometers on growth and productivity of avocado trees under microirrigation. The predominant soil series at the experimental site is Coto clay, classified as Typic Eutrustox. Planting distance was 9.1 m x 9.1 m. Trees were submitted to two microirrigation treatments scheduled by using tensiometers installed at 30-cm and 45-cm depths. Trees were irrigated when tensiometer readings reached a low depletion level (10 to 15 kPa) or a high depletion level (40 to 45 kPa). A rainfed treatment was included as check. Variables measured were canopy volume, fruit weight and number, and irrigation applied. Canopy volume of trees growing under rainfed conditions was significantly lower than that of trees submitted to either 10 to 15 kPa or 40 to 45 kPa microirrigation treatment. Trees submitted to 40 to 45 kPa showed the maximum canopy volume, 148 m3/tree, which was not significantly different from that of trees submitted to 10 to 15 kPa. Only in 2005, trees irrigated at low depletion levels produced 68 fruits per tree, an amount which was significantly greater than that of the other two irrigation treatments. In general, avocado trees submitted to high depletion level significantly increased their growth and yield.

Abstract The aim of the study was to estimate the effect of' tree pruning intensity on the content of nutrients in leaves of the ‘Łutówka’ sour cherry cultivar (Prunus cerasus L.). Between 2006 and 2010 an experiment with different tree pruning intensity was carried out. The study material consisted of first- class one-year old budded plants of the ‘Łutówka’ cultivar IR2 type, on Prunus mahaleb rootstock. The plants were planted in the spring of 2001 (orchard 1) and 2002 (orchard 2) and spaced at 4.0 × 1.3 m2, giving a total of 1.920 trees ha−1. Three pruning regimes were applied in the plantation: 1) no pruning; (only sanitation felling was applied), 2) moderate traditional pruning - branches were shortened, 3) intensive pruning by removing branches older than three years. The cherry tree pruning intensity significantly influenced the content of mineral components in leaves. The content of N increased, whereas the content of Ca and Mg decreased. The maximum temperatures at the beginning of the growth period had particularly beneficial effect on the P and K content. Chilly and dry spring limited the P and K content in the plants. The content of minerals in sour cherry leaves depended on the age of trees.
