SUMMARY
A field experiment was conducted during summer season of 2023 at Hisar, Haryana to assess the effect of fodder sorghum varieties under different fertility levels. Four varieties (CSV 53F, HJ 541, HJ 513 and HC 308) were tested at four fertility levels (control, 75, 100 and 125% recommended dose of fertiliser) in factorial RBD with three replications. Among varieties, CSV 53F performed best in terms of growth parameters as well as in yield. The highest plant height, LAI, chlorophyll content, green fodder and dry fodder yield (52.44 t/ha and 13.46 t/ha, respectively) was recorded in CSV 53F which was statistically at par with HJ 541. The highest crude protein yield and digestible dry matter yield (DDMY) was also recorded in variety CSV 53F. Among fertility levels, application of 125% RDF gave significantly higher green fodder and dry fodder yield (56.41 t/ha and 14.69 t/ha, respectively) among lower fertiliser levels but was found statistically at par with 100% RDF (75 kg N + 30 kg P2O5 + 30 kg K2O per ha). In nutshell, use of CSV 53F or HJ 541 performed better and application of 100% RDF was the most suitable fertilization practice to achieve maximum yield under semi-arid conditions of Haryana.
