SUMMARY
Present investigation was conducted during Rabi season 2018-19 at Research Area of CCS Haryana Agricultural University, Hisar. The experiment was comprised of three cutting schedules viz. 45, 55 and 65 days after sowing (DAS) as main plot treatments and six nitrogen schedules i.e. N1– 1/3 basal +1/3 at first irrigation and 1/3 after cut, N2– ½ basal + ½ at first irrigation, N3-½ basal and ½ after cut, N4– ¼ basal +½ at first irrigation and ¼ after cut, N5 – ½ basal +¼ at first irrigation and ¼ after cut, N6 – ¼ basal +¼ at first irrigation and ½ after cut as sub plot treatments. Experiment was laid out in split plot design with four replications. Among different cutting schedules, maximum plant height (65.6cm), dry matter accumulation (76.9g) and green fodder yield (247.98 q/ha) were recorded when crop was cut at 65 DAS for green fodder as compared to rest of the cutting schedules. Whereas, crop cut at 45 DAS for green fodder then left for grain produced maximum grain yield (61.36 q/ha), which was significantly higher than cut at 55 DAS and 65 DAS. Among different nitrogen schedule, at the time of cut, N2 resulted in significantly taller plants (53.3 cm) and maximum dry matter (63.1 g). Maximum green fodder yield (177.85 q/ha) was recorded when full nitrogen dose was applied before cutting (N2). Whereas, maximum grain yield (56.88 q/ha) was recorded in N3, which was significantly higher than treatment N2 and N5 but it was at par with in N1, N4 and N6.
