The treatment consisted of four moisture regimes in main plots viz., irrigation at crown root initiation (CRI) + 100 mm cumulative pan evaporation (CPE), CRI + 150 mm CPE, CRI + 200 mm CPE and CRI only, and six moisture stress management practices in sub plot viz., No moisture stress management, seed hardening (SH) by CaCl2 , SH + KCl spray at 90 days after sowing (DAS), SH + mycorrhizae application at sowing + KCL spray, SH + mycorrhizae + KCl spray + kaolin spray at 115 DAS and pusa hydrogel application at sowing. The experiment was laid out in split plot design with three replications in sandy loam soil. Days to achieve various phenological stages viz., heading, anthesis, milking and physiological maturity during both the season were found to be highest with irrigation at CRI + 100 mm CPE and lowest with irrigation at CRI only. Integrated moisture stress management practices involving SH + mycorrhizae + KCl spray + kaolin spray had favorable impact on various phenological stages. Among the different moisture regimes the treatment CRI + 100 mm CPE and among the moisture stress management the treatment SH + mycorrhizae + KCl spray + kaolin spray had produced higher grain, straw and biological yield.Not Availabl

Research articleA field experiment on FAO CROPWAT model simulated water requirement and yield reduction estimation under different moisture regimes in wheat was conducted during rabi seasons of 2010- 11 and 2011-12. Crop water requirement of wheat as estimated by CROPWAT model was 286.7 mm during 2010-11 and 304.9 mm during 2011-12. The reduction in cumulative yield under various moisture regimes predicted by CROPWAT model was 3.9, 9.1, 14.6 and 19.3% during crop season 2010-11 and 2.8, 8.6, 11.2 and 20.1% during crop season 2011-12 respectively. The yield reduction as simulated by CROPWAT model under different moisture regimes was closely collaborated with the actual yield reduction. The treatment CRI + 100 mm CPE in main plot and SH + Mycorrhizae + KCl spray + Kaolin spray in sub plot produced higher grain, straw and biological yield.Not Availabl
