Zingiber officinale was cultivated at three plant spacing viz; S-1 (30 x 20cm), S-2 (30 x 25cm) and S-3 (30 x 30cm) under Dendrocalamus strictus AFS (8 x 6m) and in open, at research farm of IGAU, Raipur (C.G.) in 2018-19. The population of bamboo have 33.38±16.23 culm per clump to 45.00±19.06 after 8 month with 5.66±0.99 diameter of clumps. The average height of bamboo was record 8.35±0.54 m with 3.56±0.77 cm diameter at 3rd internodes. The soil physical structure viz., 20-30 % sand, 20-30% silt, >45% clay with wilting point of 20.20cm, where its EC is 0.30 (ds/m) with pH of 7.5. The soil was found very rich in organic matter and other nutrients i.e., 0.67% organic carbon, 166.2 kg N ha-1, 9.7 kg P ha-1 and 544.8 kg K ha-1. The PAR was measure higher for open field crop (187.6-1003.6 µmol s-1 m-2) than crop of AFS (89.5-606.86 µmol s-1 m-2). The average temperature is more or less in similar pattern for open and AFS during growing period of crop and it was in range of 23.6-32.6 oC and 22.2-32.6 oC respectively. The average relative humidity is little higher in AFS than open field due to shading of bamboo canopy and it was over all in range of 36.0-96.0 % and 37.7-96.5 % respectively. The yield of fresh weight of rhizome was received 22.12 q ha-1 from open (CS-2) as compare to AFS (CS-1) (18.46 q ha-1). The spacing S-2 gave highest yield of 24.70 q ha-1 followed by S1 (22.37 q ha-1) and S3 (13.80 q ha-1) respectively with significant variation. In case of interaction of cropping system x spacing, the highest yield was received 26.97 q ha-1 in CS-2 x S-2 followed by 24.58 and 22.44 q ha-1 in CS-2 x S-1 and CS-1 x S-2 respectively.
