Performance of Wheat (Triticum aestivum L.) and Mustard (Brassica juncea L.) Intercropping in Relation to Row Ratio and Fertility Levels
2014
Singh, Jay Kumar | Dawson, Joy
A field experiment was conducted during rabi seasons of 2009–10 and 2010–2011 at Allahabad to assess the effect of row ratio, and fertility levels on various competitive functions in wheat (Triticum aestivum L.) alongwith mustard (Brassica juncea) intercropping. Mustard was found dominant and aggressive as compared to wheat. Wheat and mustard under 8:2 and 12:3 row ratios proved more remunerative and recorded higher yield advantage than 4:1 row ratioas judged by land equivalent ratio and relative crowding coefficient. Significantly higher aggressively (1.034) and competitive ratio (2.245) of mustard was noticed under wheat + mustard intercropping which caused drastic reduction in wheat yield. Consequently, the total land equivalent ratio and relative crowding coefficient of the system was markedly higher with row ratio of 8:2 with fertility levels of 100%=100% that gave maximum monetary advantage. Increasing fertility up to highest level correspondingly enhanced competitive ratio and aggressively of mustard. However, the reverse trend was observed on wheat for these indices. The maximum total land equivalent ratio of 1.72 and net return was observed with the application of 100%+50% recommended fertilizer to both the component crops.
