A field study was carried on drumstick (Moringa oleifera Lam) cv. PKM 1, to evaluate the effect of different planting density on vegetative morphomatrix, yield and economics under semi-arid rainfed conditions of western India. This experiment was laid out at the Krishi Vigyan Kendra-Panchmahal (ICAR-CIAH), Godhra, Gujarat. The objective of the study was to determine the best plant spacing for increased revenue. Among the evaluated different planting distance, the highest plant height was recorded in T-5 (2mx2m), having the maximum number of plant per unit area. However, the highest stem girth, plant spread (East-West) and (North-South), was recorded in T-1 However, the highest yield per plant recorded with 6mx4m distance, but on per unit area basis, T-5 (2mx2m) exhibited almost triple the yield over planting distance (6mx4m). The plant densities had considerable influence on flower emergence, flowering period, number of panicles/plant, number of flowers/panicle, % flower, number of fruits/panicle at harvest, number of fruits/plant at harvest, fruit weight, fruit length (cm), fruit girth (cm). The highest net returns ((sic) 247 081.45) and cost benefit ratio (3.67) was computed in T-5 followed by T-4 (7 191 950.40 and 3.52), T-2 ((sic) 147 359.30 and 3.33), T-3 (Rs. 99 677.40 and 3.05) and T-1 ((sic) 72 169.10 and 2.87). Based on the observations, it can be concluded that the closer planting (2mx2m) had better productivity and income than the under spacing (6mx4m) per unit area under the rainfed condition of semi-arid ecosystem.
