STUDIES ON THE NITROGEN MANAGEMENT THROUGH ORGANIC AND INORGANIC SOURCE OF NUTRIENT ON GROWTH AND PRODUCTIVITY OF LATE SOWN WHEAT (TRITICUM AESTIVUM L.)

The field experiment was conducted during rabi season of 2022-23 at Student's Instructional Farm (S.I.F) of C.S. Azad University of Agriculture & Technology, with objective to find out the effect of nitrogen management through organic and inorganic source of nutrient on growth, yield and economics of late sown wheat.The 9 treatments were tested in Randomized Block Design with three replication T 1 RDN alone though urea, T 2 RDN alone through FYM, T 3 RDN alone through vermicompost, T 4 75% RDN though urea + 25% through FYM, T 5 75% RDN though urea + 25% through vermicompost, T 6 50% RDN through urea + 50% through FYM, T 7 50% RDN through urea + 50% through vermicompost, T 8 25% RDN though urea + 75% through FYM, T 9 25% RDN through urea +75% through vermicompost.The soil of field was sandy loam, low in organic carbon (0.45%) and low in available nitrogen (170.00 kg/ha), available phosphorus (16 kg/ha) and available potash (160.00 kg/ha).The pH of soil was 7.40.The wheat variety unnat halna (k-9423) was sown on 19 of Dec.2022 at row spacing of 20 cm with seed rate of 125 kg/ha.The FYM, Vermicompost and Urea were applied as per treatments.Result showed that the T 5 gave the significantly better growth, yield contributing characters with highest grain yield (52.30 q/ha) and net return (63235.70) in comparison to all other treatments.The minimum grain yield (38.16 q/ha) and net return (30722.40q/ha) was recorded under the T 2 .
