TECHNOLOGY RAGI + PIGEON PEA (6:2)INTERCROPPING FOR HIGHER PRODUCTIVITY IN TRIBAL AREA OF ORISSA & EASTERN GHATS REGION

WHY INTERCROPPING PIGEON PEA WITH RAGI? Legume nitrogen fixing Rainfed crop Drought tolerance Perennial nature Pulse for nutritional security

CONSTRAINT IN PREVALENT CULTIVATION • Improper seed sate- poor germination • Weed control very difficult • Competition is very high due to poor seed distribution • Low input management- legume source of nitrogen

SOWING Sl no.
