Abstract
An experiment conducted at Agricultural Research Station Ummedganj, Kota, Rajasthan during Rabi (2018-19 and 2019-20). The experiment was laid-out in split plot design with four replications having sixteen treatment combinations of four sowing windows (25th October, 05th November, 15th November and 25th November) allocated in main plot and four nitrogen levels (100, 125, 150 and 200 % RDN) in sub plot. Significantly higher leaf weight/10 plants (g) and 10 plant’s stem weight (g) of ryegrass were noted when the sowing occurred on November 05th during first cutting at 45, second cutting at 75, third cutting at 105 and fourth cutting at 135 DAS over sowing of ryegrass on 15th and 25th November, respectively. Ryegrass sown on 05th November had a significantly higher green and dry fodder yield (1184 and 224 q/ha) than sown on 15th and 25th November. However, it was found at par with sown on 25th October sowing (1145 and 220 q/ha).Under 150 % RDN application at 45, 75, 105, and 135 DAS sowing on 5th November, the maximum leaf weight (g) and stem weight (g) of ryegrass were measured over application of 100% RDN and 125% RDN. Application of 150% RDN gave significantly higher green and dry fodder yield (1112 and 202 q/ha) over application of 100 and 125% RDN, but it was found at par with application of 200% RDN (1121 and 205 q/ha) green and dry fodder yield in the pooled analysis.
