Effect of organic manure and bio-fertilizer on growth and yield of papaya (Carica papaya L.) Cv. red lady

Abstract

The present investigation was carried out at Krishi Vigyan Kendra, Balod, Indira gandhi Agricultural University, Raipur, Chhattisgarh during the year 2018 -19 and 2019-20, respectively and was laid out in Randomized Block Design (RBD), the experiment comprising ten treatments and three replications. 200:200:200 gm NPK /plant were applied as per recommendation in all ten treatments combinations involving different organic manures and biofertilizers. The results revealed that the growth parameters viz., plant height (184 cm), were significantly maximum in papaya plant receiving with treatments( RDF+ FYM@ 10 kg /plant +Azospirillum@ 10 gm / plant + PSB @10 gm / plant ) Whereas stem girth (48.47cm), number of leaves(48.13), total leaf area (9.77m2) and length of petiole (70.57cm) were highest with the treatment RDF+ FYM@ 10 kg /plant +Azospirillum@ 10 gm / plant + PSB @10 gm / plant(T8) and treatment ( RDF +Azospirillum@ 10 gm / plant + PSB @ 10 gm / plant) found at par for all the growth parameters results. Number of fruits per plant(34.17), average fruit weight (1.15kg), fruit yield per plant (38.95 kg) and per ha(116.86), fruit length (22.58cm) and pulp weight per fruit (845.47gm) were found significant in papaya plants supplied with RDF +Azospirillum@ 10 gm / plant + PSB @ 10 gm / plant and fruit girth (23.15cm), fruit volume 894.17(cc) and seed weight per fruit(84.96) were found significant with treatment RDF+ FYM@ 10 kg /plant +Azospirillum@ 10 gm / plant + PSB @10 gm / plant. Likewise poor performance was observed in control for all parameters.
