| dc.description.abstract | An investigation was undertaken to develop the predictive relationship for water advance and recession in field borders with cow pea as the test crop. The experiment was conducted at the KCAET, Tavanur during February-April 1992. Border strips of 2 m width and 40m length were used for the study. The strips were laid out on three different slopes, 0.4 %, 0.3%, and 0.2%. Stream sizes of 4 Ips, 3 Ips, and 2 Ips per meter widths were used to irrigate the strips. There was nine treatments each replicated twice. Advance and recession times were noted at every 5 m distance from the upstream end of border. Advance and recession curves were plotted to draw conclusions on the effect of the three parameters viz stream size, slop and distance on advance and recession times. Uniformity of irrigation was also analysed for the different treatments and the treatment with 0.2% slope and 4 Ips/m width stream size showed the best uniformity. Multiple linear regression was done considering stream size, slope and distance from upstream end as independent variables. Advance and recession times were taken as dependent variables. Rational formulae to predict the advance and recession times were developed from the results of the multiple regression analysis. | en_US |
