Natural and productive characterization of bean in agricultural ecosystems.

Abstract

In El Salvador, yields of bean crops are very low and productions do not satisfy the demands of the population. This research was designed with the objective of solving this problem, this investigation is framed in studying the characterization of the natural and productive situation of the bean crop in the edaphoclimatic conditions, for which were used participatory tools. Several farms were randomly selected, with samples dominated by sialitic soft brown soils without carbonate. The results allowed to determine the problems related to the poor soil management, the areas dedicated to the cultivation, the varieties used by the peasants, highlighting the black ones, underlining the cuarentano negro, BAT- 304 y Cubana-24 genotypes respectively in Limonar's soil and climatic conditions. It concludes with the statement that the zones of greater frequency of appearance of the black varieties are San Juan and Limonar.
