Abstract An experiment was conducted at Post Graduate Institute Instructional Farm, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist. Ahmednagar (Maharashtra) during summer season of 2017-18 to examine the effect of integrated nitrogen (GRDF, 150 % RDN, 125 % RDN, 100 % RDN and 75 % RDN) and cutting management (single cut and double cut) on nutrient uptake and economics of forage pearl millet. The experiment was laid out in Factorial Randomized Block Design with three replications and ten treatment combinations, comprised of five fertilizer levels and two cutting managements. The application of 150% RDN (75% RDN-Fertilizer+25% RDN through FYM) recorded maximum growth and significantly higher yield attributes, quality parameters and green forage yield of forage pearl millet (767.54 q/ha). However, 125% RDN (75% RDN-Fertilizer+25% RDN through FYM) and GRDF (90:40:30 NPK kg/ha-1+3 t FYM/ha) were found to be at par to each other. Application of 150% RDN (75% RDN through Fertilizer + 25% RDN-FYM) and double cut (1st cut 65 DAS and 2nd cut at 54 days after 1st cut) recorded significantly maximum growth and yield attributes viz., plant height, number of tillers per plant, leaf: stem ratio, and the yields of green forage (932.48 q/ha) and dry matter (230.69 q/ha). The values of dry matter and crude protein content as well as in vitro dry matter digestibility (IVDMD) were significantly highest due to the application of 150% RDN (75% RDN-Fertilizer + 25% RDN through FYM). However, double cut (1st cut at 65 DAS and 2nd cut at 54 days after 1st cut) recorded significantly higher dry matter and crude fibre contents, while lower crude protein content and IVDMD. Significantly higher uptake of nutrients viz., nitrogen, phosphorus and potassium were recorded with application of 150% RDN (75% RDN-Fertilizer + 25% RDN through FYM) and double cut (1st cut at 65 DAS and 2nd cut at 54 days after 1st cut) by forage pearl millet.
