Effect of Different Nutrient and Stress Management on Accumulation of Proline in Pigeon Pea Based Multi-Tier Cropping System Under Rainfed Condition

A field experiment was conducted during the rabi season of 2014–2015 at Dry land Agricultural Research Station, TNAU, Chettinad, Tamil Nadu. There were 45 combinations comprising of different cropping system, nutrient management and stress management practices with 2 replications. Results indicatedthat Pigeon pea + foxtailmillet+ Groundnut (1: 2: 1) + 100% RDF for base crop + foliar spray of 2% DAP +1% KCl + foliar spray of PPFM @500 ml ha⁻¹ registered higher proline content in pigeon pea (42.06 and 43.76 mg g⁻¹ FW), groundnut (2.40, 3.15 mg g⁻¹ FW) and minor millets (42.06 and 43.76 mg g¹ FW) for both pre flowering and flowering stage of the crops.
