Analysis of growth and productivity of wheat (Triticum aestivum L.) in relation to levels of fym and nitrogen

The dry matter accumulation, LAI, LAD, CGR, RGR and NAR were recorded significantly higher at 20 tonnes ha⁻¹ FYM over 0 and 10 tonnes ha⁻¹ FYM at all the stages except dry matter accumulation at 45 DAS in both the years. Number of effective tillers, number of grains spike⁻¹ and grain yield enhanced significantly with the graded levels of FYM up to 20 tonnes ha⁻¹. Application of recommended dose of NPZn fertilizer significantly improved the dry matter accumulation, LAI, LAD and CGR at all the stages, except dry matter accumulation at 45 DAS; effective tillers, number of grains spike⁻¹ and grain yield at harvest over nitrogen levels. The RGR and NAR also improved significantly with recommended dose of NPZn compared with 120 kg N ha⁻¹ during both years.
