Extract

An experiment on irrigated wheat was laid out in a split-plot design in which six levels of N, three dates of sowing and two times and methods of application were tried. The data were subjected to pooled analysis and it was noticed that years, dates of sowing, manures and the interaction of manures and dates of sowing were highly significant, while the time and method of application of the fertilizer and all other interactions were non-significant. Graphs have been presented depicting the law of diminishing returns. Optimum levels of N have also been given. Application of the fertilizer by placement to normal and late sown crops is much better than its application by broadcasting.
