Abstract: Green gram or Mungdal (Vigna radiata L.) is an important pulse crop and Melia composita (Malabar Neem or Nimabaro) is an emerging industrial agroforestry plantation in southern Gujarat. To maximize the land utilization an agroforestry trial was laid to investigate the performance of okra varieties under different spatial arrangements of 2 year old Melia composita plantation with three spacing of S₁ (2 x 2m), S₂ (2x 3 m) and S₃ (2x 4 m) while S₀ as open field at College of Forestry (ACHF), Navsari Agricultural University, Navsari, Gujarat, India, during winter season of 2015-16 and 2016-17. Green gram crop (GV_1- Meha and GV₂- GM-4) were intercropped with M. composita reported lower growth parameters as well lower yield as compared to open condition. The results of pooled analysis of two years shown that treatment T₂-S₀ GV₂ recorded maximum plant height -48.23cm, number of branches per plants- 3.62, number of leaves- 247.42 number of flower per plant -34.04, average number of pod per plant- 21.31, seed yield per plant- 4.94g and per hectare- 0.81 tonnes in open condition. Similarly in intercropping the growth and yield attributes of Okra were minimum height -36.12 cm, number of branches per plants- 2.59, number of leaves- 110.57 number of flower per plant -19.13, average number of pod per plant- 15.08, seed yield per plant- 3.55g and per hectare- 0.58 tonnes were reported in T₄ (S₁ GV₂) i.e. in 2x 2 closer spacing while under wider spacing of S₂ and S₃ Green gram responded significantly better respectively. Hence wider spacing of S3 (2 x 4 m) can be suggested for intercropping under M. composita plantations in initial 2-4 years.
