The objetive was to quantify the trend in the Productive Gross Value (PGV) and the productivity per ha in the state of Baja
California Sur, Mexico from 1990-2006. The goal was to determine the impact over that productivity of change in the crops pattern, the physical yield of crops and the real prices per unit of product in the Production Gross Value (PGV) and the real monetary aggregated yield (RMAY) per ha. The methods of analytic- synthetic-quantitative-qualitative and the Descriptive Economies were used by applying macroeconomic methodology structural and comparative-static focuses. A secondary macroeconomic data source analyzed was used in a sample of 127 crops. When a variable was moved (crop composition, physical yields or prices), the other ones were kept constants. Results showed that harvested area decreased 45% (from 59,875 to 32, 953 he), and the composition of crops change your percent contribution at the PGV, while in the base period, forage 8.5%, crops 42.5%, industrial crops 10.4%, hortofruticolas 36.5%, organic 0%, aromatic weeds 0.9%, ornamental plants 1.1%, in the period 2004-2006 was 4.7%, 0.4%, 73.7%, 16.5%, 0% y 0.3% respectively, which increased the PGV in 96% (from $1,030 to $2,022) and increased the RMAY in 257% (from $17,216 to $61,379). The physical yield was increased in 170%, which increased the PGV in 154% (from $796 to $2,022) and elevated the RMAY in 154% (from $54,161 to $61,379). The real prices were high in 18 from 127 crops (corn forage, sorghum forage, sorghum escobero, berenjena, brocoli, citric, datíl, been, asparagus, higo, napa, orange, repollo, cherry tomato, red tomato, taco palm, Bermuda grass and
buffel grass, which brought and increasing effect of 53% in the PGV (from 1,318 to $2,022 millions of pesos) and 53% in the RMAY (from $40,024 to $61,379 millions of pesos).
