Abstract

Weed free treatment resulted in maximum plant height, yield attributes and grain and straw yields of maize and blackgram. Amongst the herbicides, maximum values of above observation were recorded when metolachlor @ 1.0 kg ha −1 was applied. Planting in 2:2 rows of maizeblackgram intercropping proved superior in all observations recorded, over 1: 1 row planting system.
