Effect of organic manure and bio-fertilizer on quality and benefit: Cost ratio 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 fruit yield per plant (38.95 kg) and per ha(116.86), were found significant in papaya plants supplied with RDF +Azospirillum@ 10 gm / plant + PSB @ 10 gm / plant. Regarding quality parameters, lowest titratable acidity (0.015%) and higher content of total soluble solids(8.00Brix), total sugars (9.73%), were also noted in treatment RDF +Azospirillum@ 10 gm / plant + PSB @ 10 gm / plant and Maximum reducing sugars (8.79%) and minimum non- Reducing sugar (0.94%) found with the treatment RDF+ FYM@ 10 kg /plant +Azospirillum @ 10 gm / plant + PSB @10 gm / plant. The highest net realization of Rs. 711911.00 per hac and greater benefit cost ratio (6.7) was obtained with RDF +Azospirillum@ 10 gm / plant + PSB @ 10 gm / plant. Likewise poor performance was observed in control for all parameters.
