Response of Trichoderma viride and plant growth promoting Rhizobacteria (PGPR) on growth and yield of chilli cv. Arka Lohit

Abstract

A field experiment was conducted to evaluate the Response of Trichoderma and PGPR on Growth and Yield of chilli cv. Arka Lohit. An experiment was carried out at Horticulture Complex, JNKVV Jabalpur (M.P.) during the year 2017-18. Among the various treatments of Trichoderma and PGPR, the combination of all Trichoderma viride (TV) + Pseudomonas fluorescence (PF) + Azotobacter chroococcum (AC) (2.5 kg/ha +2.5 kg/ha +5.0kg/ha) showed better response. The observation was recorded on different growth and yield attributes. The growth and yield of chilli plants were influenced by combined application of Trichoderma and PGPR (Pseudomonas fluorescence + Azotobacter chroococcum). The maximum plant height 30 DAT (Day after transplanting) was observed in treatment B3 (Trichoderma viride (TV) + Pseudomonas fluorescence (PF) + Azotobacter chroococcum (AC) 2.5 kg/ha +2.5 kg/ha +5.0kg/ha) (34.94cm), 60 DAT (43 cm), 90 DAT (52.04 cm) and 120 DAT (56.73 cm). The maximum number of branches per plant at last harvest was recorded in treatment B3 (27). The yield parameter like Average fruit weight (8.43 g), Fruit yield per plant (153.47 g) recorded highest in treatment B3 (Trichoderma viride (TV) + Pseudomonas fluorescence (PF) + Azotobacter chroococcum (AC)). Thus combine the use of Trichoderma and PGPR proved better in improving growth and yield in chilli.
