Received 18 June 2018   Accepted 6 October 2018 Acta Agriculturae Serbica, Vol. XXIII, 46(2018); 157-165  158 Introduction  Establishing a pear plantation using modern production technology is a major investment which requires a detailed organisational and economic analysis of factors such as choice of location, land preparation, choice of cultivar and training system, high-quality planting material, modern machinery, use of cultural practices and organisation of harvest, sale and placement on the market. The analysis also involves the evaluation of economic and market conditions which will affect the volume of production and choice of cultivars. Market conditions and pear marketing possibilities largely govern the economic performance of a pear orchard. Sales possibilities are based on the product demand by large consumer centres in the country and abroad, with due consideration given to the local market. The choice of cultivars is dependent on market demand and market capacity, with respect to both fresh consumption and processing, and is generally oriented to cultivars produced for export as fresh produce and for industrial processing. This study focused on the economic analysis of pear orchard establishment costs, and on the related calculation of economic parameters i.e. investment expenses and expected revenue.   Material and Methods  Research was conducted in a commercial pear orchard located in the Trbušani suburban area of Čačak (Latitude 43° 55’ 17” N; Longitude 20° 19’ 08” E; Altitude 256 m), characterised by flat terrain with no pronounced exposure. The orchard was established in autumn i.e. November 2009, using the producer's own financial resources. The nursery trees used to establish the orchard were bench-grafted in March of the same year and grown in the producer's own nursery until they were transferred to their permanent location. The BA 29 clone of Provence (Angers) quince was used as the rootstock. Plant spacing was 4 m between rows and 1.5 m within rows, which gave a plant density of 1,667 plants ha-1To perform an economic analysis, the analytical calculations method was used to calculate production expenses, planned revenue and profitability of the investment. Total revenue was calculated on a cumulative basis, starting from the years of low fruit yield, as were total expenses for the orchard establishment period until full productivity, which ensured a return on investment and profitability. . Pear trees were grown in a high-density system, and trained to spindle bush. In this high-intensity orchard, modern growing technology, also including drip irrigation, was used. Two pear cultivars were planted i.e. ‘Williams’ and ‘Santa Maria’, which exhibit fruit maturity in the second half of August.   Acta Agriculturae Serbica, Vol. XXIII, 46(2018); 157-165  159 Results and Discussion  When establishing the high-intensity pear orchard on 1 ha of land, all production parameters were recorded, costs were calculated, and calculations were provided. Costs of primary tillage and soil agromelioration treatment were based on total costs of labour, machinery, and materials used for fertilization and soil amendment (manure, mineral fertilisers, green manure and CaCO3Labour throughout the growing season is an important factor which affects the cost-effectiveness of pear production. The potential to meet labour requirements is a major determinant of both orchard size and choice of cultivars. Labour costs at a daywork rate of €20 were €670.00, and machinery costs totalled €480.00.  used for liming), and amounted to €2,685.00. Labour costs were calculated based on the rate of daywork, and machinery costs were based on the hourly rate (Table1).  Table 1. Costs of primary tillage and agromelioration treatment for a 1 ha pear orchard  Costs of primary tillage and land preparation for planting (in €) A. Labour 126.00 B. Machinery  1,760.00 C. Material 799.00 TOTAL: 2,685.00  As reported by Glišić et al. (2014), machinery costs for apricot orchard establishment were €740.00. Machinery costs include costs of land preparation for planting and material transport costs.   Drip irrigation provides the supply of water and nutrients at appropriate amounts, while minimising water losses through evapotranspiration (over 50% reduction) (Trajković and Milanović, 2012). This type of irrigation is highly cost-effective as it reduces the amount of water needed for irrigation and makes savings in labour used for irrigation, fertilisation, and system maintenance and operation. The cost of the drip irrigation system installed in the orchard and accessories was €4,000.00 ha-1 . The cost of the material used for planting the 1 ha pear orchard (nursery trees, mineral fertilisers and irrigation system) totalled €7,825.75 (Table2). Milić et al. (2013) provided establishment cost calculations for an apple orchard. Costs were €37,673.94, but they also included hail netting, fencing and frost protection costs. As calculated by Glišić et al. (2014), establishment costs for an apricot orchard, excluding irrigation and hail netting, under similar agroenvironmental conditions were €2,980.00. Also, establishment costs for a 1 ha plum orchard were €7,729.00 (Milosevic et al., 2008). Therefore, establishment costs for a pear orchard are significantly higher than those for apricot and plum orchards.  Acta Agriculturae Serbica, Vol. XXIII, 46(2018); 157-165  160 Table 2.

Well-tended trees will come to fruit early, have a longer life span, and produce high yields of good-quality fruit (Mratinić, 2012). Acta Agriculturae Serbica, Vol. XXIII, 46(2018); 157-165  161 In the spring of the first year after planting, soil tillage was performed to improve the structure of the soil compacted during planting. For normal growth, development and fruiting, pear trees should have sufficient amounts of nitrogen, potassium and phosphorus during the growing season. The rate and type of fertilisers are generally determined based on soil chemical analysis. In the first year after planting, the orchard was irrigated with 10 l water per tree. When performing irrigation, attention should be paid to critical periods: after petal fall, after the June fruit drop, during fruit development and during the differentiation of buds for the following year (Milošević, 1997). In the first year, young pear trees were protected from pests (leaf aphids, pear psylla) and disease agents (pear scab, fire blight). During the autumn, the nursery trees that did not take root for a variety of reasons were replaced with new ones.     Table 3.

Total investment per 1 ha 18,510.25  In the years after planting, 3 to 4 cultivation or tillage operations were performed to prevent weed development, crush soil crust and prevent soil moisture loss. In the autumn, the soil was treated with NPK containing increased levels of phosphorus and potassium; in the spring, CAN was incorporated. Depending on agroenvironmental conditions, disease and pest control was used. Management costs for the young pear orchard during the first three years (Table 3) totalled €6,849.5. Along with total establishment costs, total investment costs in the third year amounted to €18,510.25 (Table 3). At full productivity, all agricultural practices necessary for pear production were used. Production parameters and related costs are given in Table 4. The amount of work and number of seasonal workers were highest during pruning and harvest. A total of 55 work days were required for the harvesting operation, the cost of which amounted to €1,100 (Table 4).      Acta Agriculturae Serbica, Vol. XXIII, 46(2018); 157-165  162 Table 4.

Therefore, it is necessary to determine the optimum harvest date (mean date around which the crop must be harvested), depending on the intended use of the fruit. Fruits for fresh consumption must be harvested at technological maturity. Late harvest significantly reduces the transportability and cold storage capacity of fruit. Pear yield in the second year after planting was about 2 kg per tree. The yield of the orchard consisting of 1,667 trees/ ha was 3,334 kg. In the third year, yield was about 7 kg per tree or 11,669 per hectare. Fruit yield was low until the third year, and full productivity started in the fourth year, with 17 kg per tree. Yield at full productivity was 28,339 kg per hectare. It is noteworthy that, in years favourable for pear trees, fruit yields in high-density orchards exceeded 20 kg per tree or 30 t ha-1Pear fruits were placed on wholesale and local markets, and were also sold for export in an organised manner. The average farmgate price for first-class pears was 0.5 €/kg. Fruits that did not meet quality standards for fresh consumption were sold to processing companies to be processed mostly into brandy. Swisslion-Takovo, based in Gornji Milanovac, is a large processing company in this region, which processes 'William' pears into a brandy of the same name, and purchases pear fruit at a price of 0.25-0.30€/kg.  .  Table 5. Recapitulation of revenue and expenses in pear production   Expenses, Costs (€/ha) Revenue (€/ha) Balances (€/ha) B-A In the particular year Cumulative (A) In the particular year Cumulative (B) Orchard establishment 2,685.00 11,660.75 - - -11,660.75 Year 1 2,020.25 13,681.00 - - -13,681.00 Year 2 1,803.25 15,484.25 1,466.96 1,466.96 -14,017.29 Year 3 3,026.00 18,510.25 5,134.36 6,601.32 -11,908.93 Full productivity 4,657.00 23,167.25 12,468.80 19,070.12 -4,097.13  The yield ratio of first-class to second-class pear fruit was 70:30% on average, and was accordingly used for revenue calculations across years. Given Acta Agriculturae Serbica, Vol. XXIII, 46(2018); 157-165  164 the average farmgate price of 0.5 €/kg for first-class pears and 0.3 €/kg for second-class fruit, the revenue achieved is presented in Table 5.  Table 5 shows that the return on investment in the commercial pear orchard was achieved in the fifth year, along with profit. If the intensive orchard produced a yield higher by 35% than the average yield projections, as typical of high-density systems, the return on investment would be achieved in the fourth year. At full productivity, the difference between revenue and expenses was €7,811.8 on an annual basis. Pear production should be based on obtaining first-class good-quality fruit to generate a higher farmgate price and, hence, a higher value of production. Good-quality pears are mostly exported to foreign markets, particularly to Russia.  Conclusions  The results of the agroeconomic analysis of establishing a 1 ha pear orchard suggest the following: - Total orchard establishment and management costs during the first three years are €18,510.25. - Orchard management costs at full productivity are €4,657.00. - The return on investment in a commercial pear orchard, along with profit, is achieved in the fifth year.

Poslednjih decenija postojale su velike oscilacije u količini i kvalitetu plodova kruške iz više razloga (zastarela tehnologija gajenja, šarenilo sortimenta, pojačan napad prouzrokovača bakterijalne plamenjače, nestabilno tržište, itd.). Kako u Srbiji postoje povoljni prirodni uslovi, a na domaćem i inostranom tržištu kruška je deficitarna, poslednjih godina raste interes proizvođača za gajenjem kruške. Od uslova tržišta i mogućnosti plasmana kruške zavise u velikoj meri ekonomski rezultati. Pre zasnivanja zasada neophodno je izvršiti sveobuhvatnu analizu agroekonomskih uslova, od kojih zavisi i izbor sortimenta i veličina zasada, pa je cilj rada bio analizirati troškove ulaganja u podizanje zasada kruške. Za ispitivanje su uzete dve sorte Vilijamovka i Santa Maria. Rezultati agroekonomske analize pokazali su da investiciona vrednost podizanja 1 ha zasada iznosi 8975,75€. Troškovi nege zasada u prvoj godini iznose 2020,25€, u drugoj 1803,25€, a u trećoj 3026,00€. Ukupno ulaganje u podizanje i negu zasada u prve tri godine iznosi 18510,25€. Troškovi nege zasada kruške u punoj rodnosti su 4657,00€. Investiranje u proizvodni zasad kruške otplaćuje se u petoj godini i ostvaruje zarada. Ukoliko bi intenzivni zasad ostvario veći prinos za 35% od prosečno planiranog, što je odlika proizvodnje u gustoj sadnji investicija bi se otplatila u četvrtoj godini.
