The study aims to shed light on the cost of palm production in terms of the relative importance of cost items and statistical measurement of cost functions in both short and long term. Estimation of the productive and economic efficiency of the palm crop inside the sample. The estimates obtained for the function of the costs of the first category (less than 2 fad.) and the study of the different images of the date palm production costs in the short term according to the nature of the data obtained, shows that the cubic picture of the sample farms was better economically and statistically in contrast to other images Some do not agree with economic reasoning, others do not agree with statistical reasoning. Equal to the marginal cost of selling a ton of about L.E 2,000, it turns out that the maximum volume of profits was about 6.2 tons/acre. By deriving the average cost function, the optimal volume of production (civil cost) of about 4.4 tonnes/fad. was obtained, which is less than the actual production volume of about 4.21 tonnes. The cost category II (2-4 fad.) function showed that the maximum volume of profits was about 5.9 tonnes/fad. The actual volume of production is about 4.24 tons. Results for the category 3 cost (4 fad. more) indicated that the maximum profit was about 6.2 tonnes/fad. By deriving the average cost function, the optimal volume of production (civilian cost) of about 4.4 tonnes/fad. was obtained, which is less than the actual production volume of about 4.6 tonnes. A sample costing function showed that the maximum volume of profits was about 5.8 ton/fad. By deriving the average cost function, the optimal volume of production (civil cost) of about 4.0 tonnes/fad. was obtained, which is less than the actual production volume of about 4.31 tonnes, confirming that the study sample works in the economic phase of the law of diminishing returns Less than the one. As for profitability indicators, the results indicate that the return on variable costs has reached a minimum of about L.E 6.34 thousand/fad. (equivalent to L.E 1.51/kg) for the first tenure category, while the maximum amount was about L.E 7.43 thousand/fad. (equivalent to L.E 1.62/ for the third tenure category, with a general average of about L.E 6.73 thousand/fad. (equivalent to L.E 1.56/kg) at the level of the total farms sample. The minimum return to cost ratio was 2.16 for the first tenure category, while the maximum ratio was 2.66 for the third tenure, with an overall average of about 1.36 for the total farms. The results showed that the yield of the L.E invested reached a minimum of 115.9% for the first holding category, while its maximum reached about 166.09% for the third holding category, with an overall average of 136.16% for the total farms. The results indicated that the profit margin ratio of the product reached a minimum of about 53.68% for the first holding category, while its maximum limit was about 62.42%. For the third holding category, with an average of about 57.66% of the total farms of the sample. From the above, it shows that the net yield/fad. is increasing with the increase in the size of fad. holdings, which indicates the need to expand the area of ​​palm crop to achieve the maximum possible return for the producers of this crop.
