SUMMARY
A field experiment was carried out at Post Graduate Instructional Farm, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist. Ahmednagar (Maharashtra) during summer, 2018-19.The experiment was laid out in Factorial Randomized Block Design with eight treatments and four replications. The application of 125% RDN (75% RDN- through urea + 25% RDN –through Vermicompost) and second cutting management treatment (1st cut at 80 DAS and 2nd cut 60 days after 1st cut) recorded significantly maximum growth and yield attributes viz., plant height, number of leaves/plant, leaf : stem ratio, green forage yield (703.21,663.67 q/ha), dry matter yield(140,130.83 q/ha), crude protein yield (11.61,10.32 q/ha) and crude fiber yield (41.51, 39.24 q/ha), respectively. The extent of expression of a quality parameter IVDMD (62.13%) was recorded significantly highest with application of 125% RDN (75% RDN- through urea + 25% RDN -through Vermicompost) and first cutting management cut treatment (1st cut at 80 DAS and 2nd cut at 50 days after 1st cut) was recorded significantly highest IVDMD (61.84%). On the basis of economic studies application of 125% RDN (75% RDN- through urea + 25% RDN -through Vermicompost) INM fertilizer level with second cutting management treatment (1st cut at 80 DAS and 2nd cut at 60 days after 1st cut) was found most remunerative to obtain significantly the highest net monetary returns (Rs. 77691/ha and Rs. 72794/ha) and B : C ratio (2.85 and 2.81), respectively.
