TAILIEUCHUNG - The effect of crop losses during pre harvest and harvest periods on production costs in tomato production in the ayafl and Nallihan districts of Ankara province

The aim of this research was to analyze the impact on unit crop cost of crop losses that occur during the pre-harvest and harvest periods. It is understood today that crop losses occurring during these periods have an impact on crop cost and a negative effect on profit. | Turk J Agric For 29 (2005) 499-509 © TÜB‹TAK The Effect of Crop Losses during Pre-Harvest and Harvest Periods on Production Costs in Tomato Production in the Ayafl and Nall›han Districts of Ankara Province* F.

Çanakkale - TURKEY Received: Abstract: The aim of this research was to analyze the impact on unit crop cost of crop losses that occur during the pre-harvest and harvest periods. It is understood today that crop losses occurring during these periods have an impact on crop cost and a negative effect on profit. The Ayafl and Nall›han districts of Ankara province, where tomato production is carried out intensively, were selected as the research areas. Dwarf tomatoes are grown in the Ayafl district and indeterminate tomatoes in the Nall›han district. A sample size of 74 for Ayafl and 34 for Nall›han was calculated using a simple random sampling method. The production cost per kilo was $ and $, respectively, for these research areas. The gross margin and net profit per unit area were higher in Ayafl than in Nall›han. A higher crop loss was seen in Ayafl () compared to Nall›han() with respect to the seedling production period, as a fraction of all crop losses that include the pre-harvest and harvest periods. The crop losses during the production period in the field were in Ayafl and in Nall›han. For the harvest period, crop losses were in Ayafl and in Nall›han. Accounting for crop losses, per kilogram cost to produce tomatoes was $ for Ayafl and $ for Nall›han. Key Words: Tomato production, crop losses, production cost, gross margin and net profit.
