The research was conducted at the Teaching and Research Farm of the Institute for Agricultural Research, Ahmadu Bello University, Zaria located on latitude11011’N, longitude7038’E and 686m above sea level in the Northern Guinea Savanna Ecological Zone of Nigeria during 2010 and 2011 cropping seasons. The trial was established to study Growth and yield of okra as influenced by weeding regimes in Samaru, Zaria. The experiment was made of four treatments, replicated three times and laid out in a Randomized Complete Block Design (RCBD). From the results of this trial, 4 Weeding regimes significantly produced the highest mean values of growth and yield parameters such as plant height, number of leaves/plant, number of branches/plant, leaf area/plant, number of pods/plant, pod yield per plot and pod yield/ha throughout the period of this study, while the Control treatment significantly gave the lowest mean values of both growth and yield parameters at the same period of measurement. This results showed that the more the weeding regimes, the more the increase in growth and yield parameters. However, the less the weeding regimes, the lower the increase in growth and yield parameters of okra during 2010 and 2011 cropping seasons.
