Green manuring crops and nutrient management practices need to be improvedfor sustained and increased productivity. A field experiment was conducted for twoconsecutive years at Post Graduate Institute Research Farm of Mahatma Phule Krishi Vidyapeeth Rahuri during 2013- 2014 and 2014- 2015. To study the performance of nutrient management in potato preceding by green manuring crops. The results revealed that,incorporation ofdhaincha at 50 % flowering stage as a green manuring crop in kharif season followed by growing of potato in rabi season with 100% general recommended dose of fertilizers (GRDF-120:60:120N, P205, K20 kg ha~(-1) + 20 tons of farm yard manure ha~(-1)) found superior for recording higher nutrient uptake, grade wise potato yield and economics of potato.
