Grapevine (Vitis vinifera L.) is one of the major fruit in Pakistan and its 70% of area lies in Baluchistan, Khyber Pakhtunkhwa and Pothwar region of Punjab while Baluchistan is the major contributor in country total production. Annual country production of grapevine is 122 thousand tons with average yield of 19 tons/ha against the potential yield of 25 tons/ha. Main cause of low productivity is due to heavy weed infestation. Effective weed control is vital, as weeds use most of space, sunlight, water and nutrients due to their fast growth habits. A mall-scale intercultural implement by means of three shapes of blades with treatment T1 L-shape, treatment T2 C-shape and treatment T3 J-shape blade, suitable for small farmers under existing field conditions was developed during 2018-19. Implement performance was evaluated at Arid University Research Farm Koont, Chakwal, North Punjab, Pakistan in grapevine yard. Field performance of implement was tested for weeding efficiency, plant damage, speed, depth, theoretical field capacity, effective field capacity, field efficiency, fuel consumption and operational cost. Data recorded was statistical analyzed using Randomized Complete Block Design. Software statistic 8.1 was used for ANOVA and treatment means were compared at 5% level of probability. Treatment T1 with L-shaped blade had the better performance as compared to other shape of blades in grapevine yard.
