Fodder quality of rabi fodder sorghum (Sorghum bicolor L. moench) as influenced by spacing and nitrogen levels

Abstract

A field experiment was conducted during rabi season of the year 2017-18 at Instructional Farm, College of Agriculture, Junagadh Agricultural University, Junagadh (Gujarat). The experiment was laid out in a Split Plot Design with four replications. The results obtained from the study revealed that the crude protein content, crude protein yield and crude fiber content of fodder sorghum were remained unaffected due to different row spacing while, crude fiber yield was significantly higher under closer row spacing of 20 cm (S1). Nitrogen content and uptake by fodder were not significantly affected by variation in row spacing. Available nitrogen in soil after harvest of crop was significantly higher under wider row spacing of 40 cm and with application of 120 kg N ha-1.
