Abstract
Changes in grain yield as affected by applied nutrients and levels of available N, P and K in soil in 'IR 8' rice (O. sativa Linn.), 'Ganga 5' maize (Z. mays Linn.), 'PHB 10' pearl millet [P. typhoides (Burm. f.) Stapf and C. E. Hubb.], 'DL 70' barley (H. vulgare Linn. emend. Bowden) and 'Kalyan Sona' and 'Sonalika' wheat (T. aestivum Linn. emend. Thell.) were studied. All the test crops except maize and 'Sonalika' wheat showed a curvilinear type of response to applied N, maize and 'Kalyan Sona' wheat to applied P, and rice and 'Kalyan Sona' and 'Sonalika' wheat to applied K. With an increase in the soil test values, the response to applied nutrients declined. In follow-up trials on wheat, the expected and actual yields corresponded closely.
