Abstract

Field experiments were carried out during the winter seasons of 1989-91 at the Unviersity research farm, Mohanpur (W.B.) to find out the suitable cropping system of potato and groundnut in the Gangetic plains of upland alluvial soil. It revealed that the sole crop yields of potato and gorundnut were superior to the respective intercrop yield of the systems. Intercrops of potato and groundnut having 3: 3 row arrangements maintained row to row 40 cm apart recorded moderate potato tuber equivalence (24.09 t/ha), highest land equivalent ratio (1.49) and maximum monetary advantage (Rs. 4,971/-) preseumably due to the highest potato yield (12 t/ha) in the system. However, potato + groundnut intercrops having 2: 2 row arrangements maintained 30 cm apart exhibited less advantage.
