EVALUATION OF WHEAT - POTATO RELAY INTERCROPPING SYSTEM IN THE MID HILLS OF SHIMLA

ABSTRACT
Wheat (Triticum aestivum L. emend. Fiori and Paol.) - potato (Solanum tuberosum L.) relay intercropping system was evaluated at Shimla during 1999-2000 and 2001-2002 for suitable cropping geometry and planting density. Potato was planted in standing wheat crop at about 45 days before the harvesting of wheat. The yield of potato was not affected due to relay intercropping over the sole crop (ranging from 282.1 to 299.2 q/ha). The highest wheat grain yield (21.73 q/ha) was obtained in pure wheat crop which was at par with that obtained in the wheat (100% population) - potato relay intercropping system (19.51 q/ha). On the basis of land equivalent ratio (LER) and area time equivalency ratio (ATER), the maximum advantage from the relay intercropping of potato in wheat was obtained when 100% of sole wheat population was maintained in relay intercropping through modification of crop geometry and adjusting intra-row spacing.
