Abstract

A study was conducted with the aim to study the effect of liquid biofertilizers on the fruit yield and quality of Guava with the growing demand for safe and high-quality fruits, as well as the growing emphasis on organic farming, the current study is beneficial for long-term production of guava. A Randomized Block Design with eight treatments and three replications was used to carry out the investigation. The experiment was carried out at the hamlet of Madhavapuram, Kuravi Mandal, Mahabubabad district, Telangana State as a on farm trial from 2019-20 to 2020-21 on 5 years old plants spaced 5.0 × 5.0 m apart. There were significant differences were observed among all the treatments under study. From the present investigation, it is found that the treatment T8 (50% RDF + Liquid Azotobacter @ 10 ml/lit + Liquid PSB @ 10 ml/lit + Liquid KSB @ 10 ml/lit) was found to be best in terms of maximum number of fruits per plant (256), fruit weight (165.50 g) and fruit yield per plant (18.42 kg). Among all treatments, T4 (100% N + Zero P2O5 + 100% K2O + Liquid PSB @ 10 ml/lit) recorded the highest TSS (15.62 %), followed by T7 (100% N + 100% P2O5 + 50% K2O + Liquid KSB @ 10 ml/lit) (11.60 %). The use of these liquid biofertilizers in conjunction with inorganic fertilizers increases biological activity, minimize fertilizer input, improves the supply of nutritional content to the plant in appropriate proportions and boost the fruit yield and quality of guava.

Conclusion

It is concluded that the treatment T8 (50% RDF + Liquid Azotobacter @ 10 ml/lit + Liquid PSB @ 10 ml/lit + Liquid KSB @ 10 ml/lit) per tree was found to be best in terms of maximum Number of Fruits per plant (256), Fruit Weight (165.50 g) and Fruit Yield per plant (18.42 kg) while the treatment T4 (100% N + Zero P2O5 + 100% K2O + Liquid PSB @ 10 ml/lit) recorded the highest TSS (15.62 %).
