The objective was to determine the productivity and profitability of the pecan (Carya illinoensis) through water pumping
in the Pequeña Propiedad sector in La Region Lagunera, Mexico. We used methodology consisting of the economic relationship Benefit-Cost, as well as various indicators of productivity per hectare and per hour of work invested. We used the following economic approaches: mathematician, structural and comparative-static as it always compared 2003-2006 versus 1990-1992. Also, we used the method of valuation at constant prices, considering the year 2002 as a basis for deflating. The results show us that the area planted, production and the value generated by the cultivation increased respectively from 1,527 to 2,652 hectares (73.7%), from 2.0 to 2.9 million ton per annum (49.7%) and from $53.2 to $77.7 million pesos (46%). The Pecan increased its percentage contribution in the totals throughout La Laguna: from 0.9 rose to 1.8% of the total harvested area and its contribution to the Gross Value of Production
(GVP) grew from 3.2 to 3.9%, while decreased from 0.07 to 0.05% of the physical volume of production of the regional agricultural GVP. The productivity per hectare diminished 13.7% in physical terms (from 1.275 to 1.101 ton / he), while the gain per hectare decreased 18% to go from $22,040 to $18,139. The diminished in profit was the result of the income per hectare decreased at an annual rate of 1.05% while the cost per hectare was 0.69%, meanwhile, the income per hectare rose due to increased yields physical per hectares (at 1.01% per annum) and the price (at 0.15% per annum). The relationship Benefit-Cost was decreased 5 percentage points to the diminished of 2.733 to 2.590. The main cost is irrigation, but the cost decrease in relative terms, therefore represent 28.9% of the total cost decreased to 26.8%, the soil preparation was urged, from 14.4% rose to 32.7% of the total cost. The hour of work became minus productive, because from 401.2 rose to 502.3 the number of kilos of nut produced per hour of work, also fell from 315 to 487 total working hours spent per ton of nut, finally, while within one hour of work it had produced $86.7 in 1990-1992, in 2003-2005 were produced $58.3 as income. The number of permanent jobs increasing from 294.8 to 640.5 persons per year, due to increasing in the surface (keeping constant the productivity) raising 73.6% the employment, as well as decrement productivity (keeping constant
the harvest surface) increasing 25.2% the employment.
