A field experiment was conducted at CCS Haryana Agriculture University, Hisar during 2005-06 and 2006-07 to study the effect of organic sources of nutrition and irrigation levels on growth and yield of wheat. The plant height, dry matter accumulation, leaf area, CGR, LAI and LAD increased with increase in irrigation frequency. The results showed that the grain yield increased by 19.4 and 22.6% in I2 over I1 and 12.5 and 14.2% in I2 over I3 (3868 and 4060 kg/ha) during 2005- 06 and 2006-07,respectively. All the growth parameters were found correlated with each other. The growth parameters namely plant height, leaf area, dry matter accumulation,CGR,LAI and LAD have significant positive relationship with grain yield during both the year. Plant height, leaf area, dry matter accumulation, CGR, LAI and LAD were significantly higher with poultry manure applied @ 225 kg N/ha over lower levels of all other organic sources of nutrition. Similarly increase in dose of organic manure from 75 to 150 and 225 kg N/ha by any sources increased the grain yield significantly during both the year. However, the grain yield of wheat was statistically at par with highest dose of 225 kg N/ha with three organic sources and with 150 kg N/ha applied through chemical fertilizer.
