Abstract: The present experiment was conducted at the Agricultural Research Farm, Institute of Agricultural Sciences, B.H.U., Varanasi, India during rainy (Kharif) season, 2012 to evaluate the effect of inorganic fertilizers and integrated nutrient management practices on the growth and yield of rice variety HUR-105 (P9). The experimental plants were grown under a randomized block design replicated thrice with 7 treatments. Combined application of 100% RDF+ S40 Zn5 B1.5 kg ha-1 significantly increased the growth parameters such as plant height, number of tiller hill-1, number of green leaf hill-1 and shoot dry weight hill-1. The next best treatments with respect to growth parameters were 100% RDF and 312 kg customized fertilizer + 85.7 kg N through urea. Leaf chlorophyll content (SPAD) value was found to be highest with the application of 312 kg customized fertilizer + 85.7 kg N through urea closely followed by 100% RDF + S40 Zn5 B1.5 kg ha-1. The yield and yield attributing characters were also higher under the combined application of 100% RDF + S40 Zn5 B1.5 kg ha-1. Application of 100% RDF + S40 Zn5 B1.5 kg ha-1markedly enhanced the gross return (Rs 84003 ha-1), net return (Rs 54448 ha-1) and being at par with other treatments recorded significantly higher gross as well as net return than control and 75% RDF + 25% N through vermicompost.
