Effect of biofertilizers on growth and yield parameters of tomato

Variety West Verginia recorded maximum plant height and number of primary branches per plant, whereas maximum number of fruits per plant and weight of fruits per plant was observed in variety DT-10. Pusa Sheetal showed good fruit size. Among biofertilizers, Azotobacter performed good for plant height, number of primary branches per plant, number of fruits per plant, weight of fruits per plant and fruit size. As far as chemical fertilizer effects are concerned, recommended dose of NPK (150 kg N + 60 kg P + 60 kg K/ha) obtained highest value of plant height, number of primary branches per plant, number of fruits per plant, weight of fruits per plant and fruit size. Biofertilizers in combination with chemical fertilizers B1N2 (Azotobacter with 150 kg N + 60 kg P + 60 kg K/ha) was found to be the best treatment and significantly influenced plant height, number of primary branches per plant, number of fruits per plant, weight of fruits per plant and fruit size.
