Economical Evaluation of Sahara Lettuce cultivar production of different planting systems

The purposes of this study were to, estimation of profitability indexes of Lettuce production and selecting of the best treatment in different systems.This study was conducted on a farm with land area of 5000 m2 in a randomized complete block design with four replications and three treatments in 2013 including: transplanting, seed planting (seeding) and delayed transplanting in Nazarabad, Karaj province. Economical analysis of this study done with Partial budgeting technique and Marginal rate of return (MRR ) by Excel. Results of this study showed that indirect planting (transplanting) to seeding and delayed transplanting increased 11.6% and 85.9%, respectively. Means of cost and gross income for lettuce production in transplanting method to seeding method increased 15% and 48.8%, respectively, while, increasing of income is more than increasing of cost production. Means of cost and gross income for lettuce production in transplanting method to delayed transplanting method decreased 2.1% in cost and increased 178.8% in income, respectively. Net income in transplanting, seeding and delayed transplanting methods was estimated 170.2, 86.5 and -32.6 million rials/ha, respectively. Marginal rate of return (MRR) for replacement of transplanting treatment instead of other treatments was estimated more than interest rate.Thus, investment in transplanting method is economic and selecting as a the best treatment.
