Rooting Behavior Of Intercropped Pigeonpea (Cajanus Cajan (L.) Millspaugh) And Sorghum (Sorghum Bicolor (L.) Moench) uri icon


  • The motlng pmnk of lndhrldual plgeonpea and sorghum plants were comparedIn monocmpplng and Intercmpplng, under different planting densltles, by use of a slmpledmulatlon appmach. Plgeonpea dld not show any characteristic advantages of rootdevelopment over sorghum, pmbably due to the presence of a hard stony layer below 30 cmwhlch consequently conflned roo1 pmllferatlon wlthln the sutfam layer of 8011. The rootlngdepth was unaffected by the cropplng pattern. The root pmllfetatlon near the plant baseIncreased wlth plant age and was severely reduced by lntercmpplng In case of plgeonpeaThe lntercmpped sorghum had less mots lnltlally but attained a slmllar denslty asmonocmpped sorghum at later stages. It Is demonstrated that root development Isconslderably affected by the planting denslty
