Abstract
The feasibility of intercropping chickpea, lentil and rapeseed in wheat under rainfed condition was investigated at
Arid Zone Research Farm, D.I.Khan during 2002-03. The experiment was laid out in a randomized complete
block design with three replications. Wheat (Inqilab-91) was sown as sole crop and intercropped with chickpea
(NIFA-88), lentil (Masoor-93), and rapeseed (Dunkled) in different proportions viz; 1:1, 2: 1 and 3:1. The
experiment was sown on 2
n
November 2002. The results showed that plant height, spike length, number of
grains per spike and grain yield of wheat varied significantly among intercropping systems, while the effect on
1000-grain weight was non-significant in all cases. Plant height, spike length, number of grains per spike and
grain yield of wheat was higher with chickpea intercropping. The mean values of different proportions showed that
the highest grain yield of wheat (1687 kg ha'1) was obtained with chickpea intercropping, against the minimum
with rapeseed intercropping. Among different ratios of intercropping, the chickpea intercropping in 1:1 ratio gave
the highest grain yield (1721 kg ha') of wheat while the lowest yield of 1213 kg ha' was obtained from wheatrapeseed intercropping in 1:1 ratio.
