“The best results obtained in this regard were for the treatment (E-W crop row direction + 20 cm row spacing + hand weeding twice). Compared to control, the data recorded 43.9 % increase in crop growth (on the basis of dry matter weight) and 21.3 % in crop yield. Remarkable inhibition was also obtained on associated weeds (48.5 %) under this treatment”
