STRESS INDUCED BIOCHEMICAL ALTERATION OF PROLINE IN PIGEONPEA - SMALL MILLETS - PEANUT BASED RAINFED CROPPING SYSTEM

A field experiment was conducted during the rabi season of 2015 - 2016 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 indicated that Pigeon pea + foxtail millet + Groundnut (1:2:1) + 100% RDF for base crop + foliar spray of 2% DAP +1% KCl + foliar spray of PPFM @500 ml ha-1 were significantly higher proline content in pigeon pea (52.85 and 64.85 mg g-1 FW), small millets (12.05 and 12.65 mg g-1 FW) and peanut (3.15, 3.45 mg g-1 FW) for both pre flowering and flowering stage of the crops.
