Evaluation of SORGF Subroutines - A Consultancy Report

In the seasonally dry rainfed semi-arid tropics (SAT) crop yields are generally low and variable from year to year. The task of improving and stabilizing agricultural production in the SAT is complicated by the presence of several constraints in these areas. However, lack of water is the key limiting factor for crop production in the SAT (Virmant et al., 1980). Attempts are made through interdisciplinary research to increase and stabilize agricultural production through improved soil, water and crop management practices..
