Abstract: A field experiment was carried out during rabi season of 2017-18 at the Instructional Farm, Department of Agronomy, College of Agriculture, Junagadh Agricultural University, Junagadh. The experiment was laid out in a Split Plot Design with four replication. The results revealed that sowing of the fodder sorghum crop at 40 cm wider row spacing recorded significantly higher values of almost all the growth characters viz., Plant height, number of leaves plant-1, number of internodes plant-1, stem thickness and drymatter accumulation while, plant population at initial and final, green fodder yield and dry fodder yield of fodder sorghum were significantly higher under closer row spacing of 20 cm. The parameters such as length of internodes, leaf: stem ratio, days to 50% flowering, remained unaffected due to different spacings. The growth characters, yield attributes, quality parameters, green and dry fodder yields were found significantly higher when crop was fertilized with 120 kg N ha-1 followed by 100 kg N ha-1, except plant population at initial and final; which was not significantly affected by the different nitrogen levels. Available nitrogen in soil after harvest of crop was significantly higher under wider row spacing of 40 cm. Higher gross and net realization of 40,556 and 21,785 ha-1, respectively with B: C ratio of 2.16 was obtained when fodder sorghum crop sown at 20 cm row spacing. Maximum gross (41,544 ha-1) and net realization ( 22,912 ha-1) along with higher B: C ratio of 2.23 were observed under nitrogen level 120 kg N ha-1 followed by nitrogen level 100 kg N ha-1.
