Planting pattern in wheat (Triticum aestivum) and Indian mustard (Brassicajuncea) crop mixture under irrigated conditions in mid-hills of North-Western Himalayas

A field experiment was conducted during the winter season of 1990-91 to 199 2-93 to study the effect of planting pattern of wheat (Triticum aestivum L. emend. Fiori & Paol.) and Indian mustard [Brassica juncea (L.) Czernj. & C osson] under 2 wheat row spacings (22.5 and 15 cm) and as seed mixture unde r broadcast sowing. Wheat + Indian mustard intercropped in an 8 : 1 row com bination under both wheat row spacings and mixed cropping of wheat and Indi an mustard under broadcast sowing system did not show significant differenc e in wheat yield compared to yield of respective,sole crop of wheat. All th e inter- and mixed cropping treatments showed higher wheat-equivalent yield s, land-equivalent ratio (LER) and benefit :cost ratio over sole crops, and the highest values of these parameters were obtained under planting patter n of wheat and Indian mustard in row ratio of 8 : 1 in both wheat row spaci ngs, but 22.5 cm wheat row spacing proved more remunerative.
