Organics and bio- fertilizers effect on germination process of papaya at nursery lavel (Carica papaya L.)

Abstract

Papaya (Carica papaya L.) is an important fruit crop of tropical world. An experiment was conducted during the year 2017-2018 at College of Horticulture, Anantharajupeta, to study the influence of organics and bio-agents on process of germination in papaya (Carica papaya L.)” cv. Red lady. The present investigation was envisaged to produce robust, healthy seedlings by decreasing the duration of seedlings to be kept at nursery, before transplanting in the main field. Required growth of the seedlings was achieved through combined application of organics and bio-agents along with the potting medium. The experiment was laid out in a Randomized Block Design with three replications. The results shows that different combinations of potting media mixed with organics (neem cake and castor cake) and bio-fertilizers (VAM and Trichoderma harzianum), recorded earlier germination (7.00days), highest germination index (1.88), days taken for 50% germination (10.67), germination% (99.33%) and number of days taken for appearance of plumule (7.33), days taken for appearance of first true leaves (9.67) was recorded in potting mixture enriched with castor cake, T. harzianum and A.M fungi (T9).
