Impact of integrated nutrient management on growth, yield and nutrient uptake by wheat (Triticum aestivum)

The present investigation was carried out in the on-going long-term fertilizer experiment initiated during 1972. The long-term use of optimal dose of chemical fertilizers and FYM increased the plant height (88 cm), yield attributes [effective tillers m⁻¹ row length (98), number of grains ear⁻¹ (32) and test weight (49 g) and yield (grain (30.34 q ha⁻¹), straw (53.22q ha⁻¹), biological (83.56 q ha⁻¹) and nutrient uptake (N, P, K, Fe, Mn, Cu and Zn). The enrichment of soil with 100 per cent RDF significantly increased the plant height (66 cm), yield attributes [effective tillers m⁻¹ row length (71), number of grains ear⁻¹ (25) and test weight (41 g) and (grain (20.22 q ha⁻¹), straw (36.4 q ha⁻¹), biological (56.67 q ha⁻¹) yield and nutrient uptake (N, P, K, Fe, Mn, Cu and Zn) over 100 per cent NP and 100 per cent N.
