A field experiment was carried out at Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand, Gujarat during the summer season of the year 2015 to study the effect of time of sowing, row spacing and variety on summer cluster bean under middle Gujarat conditions, in loamy sand soil. Eighteen treatment combinations comprised of three dates of sowing viz., D₁: (21^st January); D₂: (1^st February) and D₃: (11^th February) as main plot treatments and combination of three different row spacing viz., S₁: 30 cm; S₂: 45 cm; and S₃: 60 cm along with two varieties V₁ (GG 1) and V₂ (GG 2) as sub plot treatments, were laid out in Split Plot Design with three replications. Results revealed that treatment combination D₃S₁V₂ (sowing on 11^th February with 30 cm row spacing with variety GG 2) recorded significantly higher seed yield (1476 kg ha^-1) which was found at par with treatment combination D₂S₃V₂ (sowing on 1^st February with 60 cm row spacing with variety GG 2). However, maximum net realization (Rs.50667 ha^-1) and BCR (4.53) were obtained under treatment combination D₂S₃V₂, followed by D₃S₁V₂ with net realization of Rs.48511 ha^-1 and BCR of 4.24.
