Abstract: The present investigation entitled “Effects of different nutrient management on growth attributes and yield of high yielding rice (Oryza sativa L.) varieties of Chhattisgarh” was conducted in northern hilly zone of Chhattisgarh at Rajmohini Devi College of Agriculture and Research Station, Ambikapur C.G. during kharif 2016-17. The study was comprised four treatments of nutrient management practices viz. M1-RDF (100: 60: 40 kg NPK ha-1), M2-150% RDF, M3-RDF (N– LCC) (Basal application of 30% N and full P+K and top dressing of Nitrogen as per LCC) and M4-Soil test based recommended dose for 7.0 t ha-1 grain yield (214: 42: 111 kg NPK ha-1) as main plots and five rice varieties viz. Rajeshwari, Durgeshwari, Maheshwari, Karma masuri and Indira Aerobic-1 as sub plots. The present study revealed that the maximum value of plant population (m-2), plant height (cm), number of leaves hill-1, number of tillers hill-1, dry matter accumulation (g hill-1) and crop growth rate (g day-1 hill-1) were recorded under treatment M4-Soil test based recommended dose for 7.0 t ha-1 grain yield (214: 42: 111 kg NPK ha-1) which was superior over other rest of the nutrient management practices. The application of treatment M4-Soil test based recommended dose for 7.0 t ha-1 grain yield (214: 42: 111 kg NPK ha-1) with variety Maheshwari produced maximum growth attributes and grain yield (60.83 q ha-1).
