Abstract
Sarpagandha (Rauvolfia serpentinaBenth. Ex Kurz.), a natural source of the alkaloid reserpine, is generally found growing under partial shade of deciduous forests in the tropics and subtropics. To promote its commercial cultivation under subtropical environment of the north Indian plains, a field trial was conducted during 2006–2009 to optimize the plant populations (row ratios) of pigeon pea and sarpagandha for higher productivity, land utilization efficiency and economic return in an intercropping system. Intercropping of two rows of sarpagandha with pigeon pea sown at a row distance of 90 cm proved highly beneficial in terms of total production (5.15 t ha−1 grain and 10.27 t ha−1 straw + stalk of pigeon pea and an additional dry root yield of 2.56 t ha−1 of sarpagandha) from a unit area and time. The highest land equivalent ratio, LER (2.21), area time equivalent ratio, ATER (1.76), monetary equivalent ratio, MER (2.0), land-use efficiency, LUE (198%) and net return (Rs. 273,810 ha−1) were obtained for the combination of pigeon pea and sarpagandha in 1:2 row ratio. Integration of two rows of sarpagandha as an intercrop with pigeon pea sown at 90 cm row distance is recommended for sustainable crop production.
