In Sri Potti Sriramulu Nellore district of Andhra Pradesh sorghum is a main rabi crop grown under rainfed conditions. Late or advancement of north east monsoon and prolonged breaks may have devastating effects on sorghum yield in rainfed areas of Sri Potti Sriramulu Nellore district, Andhra Pradesh even if the mean annual rainfall is normal. In this context, there is a need for intercropping systems with sorghum which are ideal even under changing climatic situations, so that farmers can meet out their basic needs of food and fodder.
A field experiment was conducted during rabi, 2018-19 and 2019-20 at Agricultural Research Station, Podalakur, Sri Potti Sriramulu Nellore, Andhra Pradesh, to find out the profitable sorghum based intercropping system for rainfed vertisols. The experiment was laid out in randomized block design with ten treatments each replicated thrice.
Sorghum intercropped with blackgram in 2:2 ratio recorded highest sorghum equivalent yield (3539 kg ha-1) and net return (Rs. 45645 ha-1).
