The experiment was comprised of three cutting schedules (45 DAS, 55 DAS and 65 DAS) as main plot treatments and six nitrogen schedules (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. Based on the research investigation, it was found that different cutting schedules significantly influenced the growth parameter, yield , yield attributes and economics of dual purpose wheat crop. Among different cutting schedule at maturity maximum plant height, dry matter accumulation (415.0g) and number of tillers per mrl (112.2) were recorded when crop was cut at 45 DAS for green fodder as compared to rest of the cutting schedules. Crop cut at 65 DAS took significantly higher days to 50% heading and maturity as compared to cut at 55 and 45 DAS. Crop cut at 45 DAS for green fodder and left for grain resulted in maximum number of effective tillers per mrl (102.87), grains per ear head (47.61) and 1000 grain weight (42.57g), which were significantly higher than crop cut at 55 DAS and 65 DAS for green fodder. Whereas, crop cut at 65 DAS for green fodder resulted in significantly higher green fodder yield (247.98 qha-1) as compared to crop cut at 45 and 55 DAS. Crop cut at 45 DAS for green fodder produced maximum grain yield (61.36 qha-1), straw yield (98.12 qha-1) and biological yield (159.49 qha-1), which was significantly higher than cut at 55 DAS and 65 DAS. Whereas, minimum grain yield (47.42 kg ha-1) and biological yield (114.04 q ha-1) were recorded when crop cut at 65 DAS for green fodder. When crop was cut for green fodder at 65 DAS resulted in significantly higher gross (`181644 ha-1) and net returns (`79820 ha-1) and B C ratio (1.78). Nitrogen schedules significantly increased growth parameter, yield performance and economics of wheat crop. Among different nitrogen schedule, at maturity N3 resulted in significantly taller plants (65.6 cm), maximum dry matter (364.3 g) and number of tillers (109.0 mrl) as compared N2. Nitrogen schedules did not affect phenology of the crop significantly. Maximum number of effective tillers, grain per ear head and 1000 grain weight were recorded when half nitrogen applied as basal and rest of nitrogen was applied after cut. Maximum green fodder yield (266.25 qha-1) was recorded when full nitrogen dose was applied before cutting i.e. half nitrogen dose was applied as basal and remaining half dose of nitrogen was applied at first irrigation (N2). Whereas, maximum grain yield (56.88 q ha-1) and biological yield were recorded when half nitrogen dose was applied as basal and half dose of nitrogen was applied after cut which was significantly higher than treatment in N2 and N5 but at par with in N1, N4 and N6. Whereas, minimum grain yield (54.09 qha-1) was recorded with N2. Maximum gross return (`179168 ha-1), net return (`77344 ha-1) and B C ratio (1.76) were recorded when nitrogen were applied as ¼ basal + ½ at first irrigation and ¼ after cut. For dual purpose wheat one cut at 65 DAS for green fodder along nitrogen (150kg ha-1) applied in split doses i.e. ¼ as basal + ½ at first irrigation and ¼ after cut or 1/3 basal + 1/3 at first irrigation and 1/3 after cut was found economically better.EnglishThesis
