Effect of different organic sources and biofertilizers on guava (Psidium guajava L.) cv. Allahabad safeda

Abstract

An investigation was conducted at Regional Fruit Research Station, Vengurla of Maharashtra, India to standardize the organic nutrient with biofertilizers management protocol for guava. In this experiment, various organic sources along with various biofertilizers combinations were tested on seven year old guava cultivar Allahabad Safeda to study the effect on fruiting and yield. The result obtained showed higher flowering (92.33%) and TSS (10.370B) by application of Vermicompost (30 kg/plant) + Azospirillum culture (250 g/tree) + PSB @ 250 g/tree. Maximum average weight of fruits (400.00 g), yield of fruits (29.60 kg/tree and 11.84 t/ha) and minimum acidity (0.19%) was recorded with Vermicompost (30 kg/plant) + Azospirillum culture (250 g/tree) + PSB @ 250 g/tree + Vermi wash foliar spray (dilution with water @ 1:1). Maximum number of fruits produced per plant (85.00 fruit/ plant) was found from plant fertilized with FYM (30 kg/plant). From the present study, it can be concluded that addition of biofertilizers along with organic manures was more effective than use of organic manure alone in enhancing fruit growth and qualitative parameters in guava.
