A field experiment was conducted on vertisols during khalif seasons of 1992–93 and 1993–94 to study the influence of cropping system, row proportions and greengram population levels in pigeonpea based intercropping systemg on dry maller production and its accumulation in different plant parts of greengram viz., stem, leaves, petioles and pods. lntercropping with pigeonpea significantly influenced the dry matter production of greengram at 50 days after sowing (DAS) and at harvest. The sole crop of greengram at 50 DAS produced significantly higher dry matter (12.54 9 plant−1) when compared,to the intercropped greengram (9.97 9 plant−1) and similar trend was observed at harvest. The accumulation of dry matter in different plant parts of greengram is also significantly influenced by intercropping with pigeonpea. The greengram intercropped under different row proportions with pigeonpea influenced the dry matter production and its accumulation in greegram significantly. The intercropped greengram under 2:2 row proportion of pigeonpea and greengram produced significantly higher dry matter (12.52 9 plant−1) at harvest when compared to 2:1 row proportion (9.73 9 plant−1). Greengram population levels significantly influenced the dry matter production and its accumulation in different plant parts. Significantly higher dry matter is produced and accumulated under 50 per cent population level than that of 100 per cent.
