Abstract

In a trial conducted at Rajendra Agricultural University Farm with three irrigation levels(0.4, 0.6 and 0.8 IW: CPE ratios), two crop geometries (single and paired rows) and three intercrops (mustard radish, and coriander) along with a sole crop of maize, the inter-cropping of mustard or radish with winter maize resulted in higher yield equivalence as compared to coriander or pure crop of maize. Among irrigation levels 4 or 5 irrigations either through IW: CPE ratio of 0.6 or 0.8 gave higher yield in comparison to irrigations scheduled through 0.4 ratio. Paired row sowing out yielded the conventional single row sowing. Plant height, effective length of cob and grain harvest index were significantly higher in case of IW: CPE ratio of 0.8 as compared to 0.6 or 0.4 Mustard (ral) relatively depressed the growth of maize as compared to other intercrops.
