Effect of organic nitrogen management practices on growth attributes of wheat (Triticum aestivum L.)

A field experiment was conducted to evaluate the effect of different organic nitrogen management practices on growth parameters of wheat (Triticum aestivum L.). The experiment comprised eight treatments involving different combinations of Farm Yard Manure (FYM), split nitrogen application through irrigation, Jeevamrit, and Panchagavya under organic nutrient management practices. The experiment was laid out in a Randomized Block Design with appropriate replications during the rabi season. Observations on emergence count, plant height, dry matter accumulation, and number of tillers were recorded at different growth stages. The results revealed that the application of 50% Recommended Dose of Nitrogen (RDN) through FYM as basal along with split nitrogen application through irrigation supplemented with Jeevamrit @ 500 L ha-1 and Panchagavya @ 3% spray (N8) significantly enhanced all growth parameters of wheat. The treatment N8 recorded the highest emergence count (136.00), plant height at harvest (112.07 cm), dry matter accumulation at harvest (46.57 g plant-1), and number of tillers at harvest (107.00). This treatment was found statistically superior over other treatments and closely followed by N7 comprising 75% RDN through FYM as basal + 25% RDN through irrigation along with Jeevamrit and Panchagavya spray. The lowest values for growth parameters were observed under N1, where 100% RDN was applied through FYM as basal application alone.
