摘要

Subsequent to the development of O-R model, there was a need to assess its utility under different climatic conditions. This included collection of data on soil moisture within the root zone for different plants under different climatic conditions. The field experiments were carried out under controlled conditions at IIT Roorkee, India. The efficacy of O-R model over other non-linear and logarithmic root uptake models was established using field data [3]. Since reference crop evapotranspiration is one of the important parameters involved in development, validation and detailed investigations of the root uptake research, various models to compute irrigated reference evapotranspiration have been compared in a study by Kumar et al. [4]. Further to substantiate the non-linearity in root water uptake an empirical model for non-linear root uptake parameter B of O-R model was developed and validated using field crop and moisture uptake data [5]. O-R model was further validated by Kumar et al. [6] for stratified soils. In addition to the efficacy of non-linear root uptake parameter 6 of O-R model, another parameter a was investigated in their study by Shankar et al. [7], which suggests further work on this parameter. The work on prediction of root water uptake also involves several close collaborations with international institutes, namely McGill University,.
