Costos de produccion de cultivos temporeros 1980

This report describes this methodology and presents the actual production cost data for 1980 in both record book and summary form. As envisioned by this methodology, production cost data is collected through direct farmer interviews and recorded on single page entries in a record book. Farmers are asked to specify the individual production tasks for particular crops, such as preparing land, applying inputs, seeding, weeding, and harvesting. For each task, data are collected on the month of activity, amount of task completed (i.e., how many seeds were planted), unit of input (gallons, laborers per day), value per unit, and total task cost. In addition, crop varieties are specified, yields are determined, and costs per unit are calculated. For classification purposes, an 8-item code is assigned to each record to identify the SEA region in which the farm is located, the type of crop cultivated, the seeding and watering (irrigation) techniques used, the level of input use (none, low, medium, and high), the system for preparing the land (manually, with animals, or mechanically), the productive capacity of the land, and whether a crop requires any special technology package, e.g., mechanical collection for a given grain. To create a viable and representative picture of farm production data, the farmers interviewed should cultivate those crops deemed most important to the regional or national economy; use technology packages most common in the area; cultivate a medium-sized plot of land; and be able to record solicited information reliably and accurately. In addition to actual production data for 1980, included are interviewing directions and guidelines and instructions on how to tabulate collected data and make required calculations.
