An experiment was laid out in factorial Randomised Block Design with two cultivars viz., Alankar and Abhinav, three planting geometry patterns i.e. 120 cm x 40 cm (2.08 plants per m2), 60 cm x 60 cm (2.78 plants per m2) and 75 cm x 40 cm (3.33 plants per m2) and three levels of nutrition levels i.e. 120: 60: 60 NPK kg/ha, 150: 75: 75 NPK kg/ha and 180: 90: 90 NPK kg/ha, thus making a total of 18 treatment combinations to find out the influence of plant geometry and nutrition in Processing cultivars of tomato under Chittoor district conditions of Andhra Pradesh. Abhinav cultivar showed superiority in mean fruit weight, no of fruits per plant, pulp weight, yield/plant and yield/ha.. Planting geometry of 60 cm x 60 cm recorded significantly the highest mean fruit weight, number of fruits per plant, pulp weight, and yiels /plant. Application of 180: 90: 90 NPK kg/ha through fertigation recorded the highest mean fruit weight as well as other yield parameters. Days from a thesis to harvesting were at the earliest in case of the cultivar Alankar, planted at 120 cm x 40 cm spacing with application of 120: 60: 60 NPK kg/ha.
