Water consumption use of cotton (Gossypium Sp.) at different soil types

Abstract

This study was conducted to determine the water consumptive use (ET) of cotton growth in three soil types and to estimate the potential evapotranspiration (PET) in a cotton field with the use of Penman's empirical formula and correlate the same with the actual measurements. Nine concrete lysimeter tanks (drainage type), each holding a cubit meter of soil was used in this study. Results of the study showed no significant differences in mean daily ET among the three types of soil tested. There was high positive linear correlation between PET and ET. Likewise, PET was found closely related with open pan evaporation (Epan). The crop coefficient (Kc) of cotton was dependent upon the stage of growth and development of the crop. The generally large values of Kc during the midseason (boiling) stage was indicative of high evapotranspiration rates of the crop during this period. Plants grown in sandy clay loam soil generally performed better than those raised in sandy loam and clay soils. Plants raised in sandy clay loam soil grew taller and performed better in terms of the number of squares, flowers, bolls, and ultimately in seedcotton yield than those in sandy loam and clay soils.
