Performance of nutrient management in potato preceding by green manuring crops

The present investigation was conducted at Department of Agronomy, Mahatma Phule Krishi Vidyapeeth, Rahuri, Ahmednagar, Maharashtra to study the performance of nutrient management in potato preceding by green manuring crops for two consecutive years during 2013–14 and 2014–15.The soil of experimental field was sandy clay loam in texture with low in available nitrogen (168.33 kg/ha), medium in available phosphorus (22.43 kg/ha) and high (361.30 kg/ha) in available potash. The experiment was carried out in split-plot design with three replications. The incorporation of dhaincha 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: 120 N, P₂O_s and K₂O kg/ha+20 t of farm yard manure/ha) found superior for recording maximum potato tuber yield (35.03, 38.61 and 35.81 t/ha) in 2013–14, 2014–15 and pooled data.
