The field experiment was conducted at the East farm of Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal District in the Rabi season during January to March 2016. Results revealed that the time of harvesting the recommended fertilizer dose applied plot registered significant plant height (121.9 cm) followed by 3% at 10 days interval registered (113.5cm). The recommended dose of fertilizer applied plot and 3% at 10 days interval registered higher green forage and dry matter yield (28.8 and 26.9 t/ha) 6.44 and 5.18 t/ha respectively and while, the control plot without fertilizer and panchagavya spray registered significantly lower green forage and dry matter yield (14.5 and 14.5 t/ha). B:C ratio is highest in 2 % at 20 days interval treatment plot produce benefit of 2.71 for every 1.00 rupee of invested while, lower cost of cultivation in control plot was 1.64.
