A field experiment was conducted at College Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand (Gujarat) to study real time nitrogen management through organic and inorganic sources during rabi season of the years 2013-14 and 2014-15 on loamy sand soil, low in organic carbon and available nitrogen, medium in available phosphorus and high in available potassium. Significantly higher growth parameters viz; periodical plant height, periodical dry matter accumulation and periodical number of tillers per metre row length were found with application of 60 kg N/ha in two equal splits at 52 and 66 DAS when LCC=4. Results further revealed that yield attribute viz; number of effective tillers per meter row length, length of spike, number of spikelets per spike, number of grains per spike and test weight was found significantly higher under the same treatment. Though appreciably higher grain (4111 kg/ha) and straw yield (5343 kg/ha) of wheat were observed under treatment with 60 kg N/ha application in two splits when LCC=4, it was found alike for 60 kg N/ha application in two splits at 25 and 45 DAS when LCC=5 and 40 kg N/ha application in two splits at 50 and 62 DAS when LCC=4.
