A field experiment was conducted during the ralny (kharif) and winter (rabr) seasons of 1994-95 and 1995-96 at New Delhi, to study the effect of nitrogen, chlormequat chloride and FYM applied to cotton (Gossypium hirsutum L.) and their residual effect on succeeding wheat (Triticum aestivum L. emend. Fiori & Paol.) crop. The treatment comprised 2 levels of FYM (0 and 10 tonneslha), 3 of nltrogen (0, 50 and 100 kg Nlha) and 3 of chlormequat chloride (0, 50 and 100 ppm). Results showed that FYM @ 10 tonneslha gave signlflcantly more bolls1 plant, higher boll weight and seed-cotton yield than that of no FYM. Nitrogen application significantly increased bollslplant, boll weight, seed-cotton yield and N uptake over the control. Spraying 50 pprn chlormequat chloride gave significanly more bollslplant, boll weight and seed-cotton yield than those of 0 and 100 ppm. The FYM left the highest residual effect on succeeding wheat crop. The highest net returns in cotton-wheat system was registered with FYM Q 10 tonnesfha, followed by 100 kg Nlha and chlormequat chloride Q 50 ppm.References
