Description A field investigation entitled ?Optimizing the spacing and row arrangements for turmeric (Curcuma longa L.)-okra (Abelmoschus esculentus L.) intercropping system? was carried out at Students? Research Farm, Department of Agronomy, Punjab Agricultural University, Ludhiana during 2015-16 on loamy sand soil having low available N and organic carbon and medium available P and K using randomized complete block design with four replications. The treatments were, T1: sole turmeric at row to row and plant to plant spacing of 30x20 cm (recommended), T2: sole okra at 45x20 cm (recommended), T3: turmeric at 30x20 cm+one row of okra in the centre (1:1), T4: after each two rows of turmeric at 30x20 cm+one row of okra in the centre (2:1), T5: turmeric at 45x13.5 cm+one row of okra in the centre (1:1), T6: after each two rows of turmeric at 45x13.5 cm+one row of okra in the centre (2:1), T7: turmeric at 60x10 cm+one row of okra in the centre (1:1) and T8: turmeric at 60x10 cm+two rows of okra in the centre (1:2). The emergence count, plant height, dry matter accumulation, tiller count, photosynthetic active radiation, leaf area index, fresh weight and number of rhizomes were significantly higher in sole turmeric over intercropping systems. Significantly higher weed suppression was observed in intercropping systems over sole turmeric and okra. The fresh, dry and turmeric processed yield and oil and curcumin yield were significantly higher under T1 than the intercropping systems. In contrast to ascendency of sole crop in growth, the combined use of resources by turmeric and okra as intercrop in T4 was significantly higher over T1 in turmeric rhizome equivalent yield, gross and net returns, LER and total uptake of N, P and K by 8.8, 8.8, 12.9, 62.0 and 18.9, 16.8, 7.8 per cent, respectively. The Aggressivity and CR indicated that okra as intercrop dominated the turmeric.
