Effect of organic manures and bio-fertilizers on growth and yield of papaya (Carica papaya L.) cv. Red Lady

Abstract

An experiment was conducted at Experimental unit (Pilikothi) Department of Horticulture, Tilak Dhari Post Graduate College, Jaunpur during 2019-20 to assess the effect of organic manures and bio-fertilizers on growth and yield of papaya (Carica papaya L.) cv. Red Lady. The saplings of papaya were transplanted on 15th October with a spacing of 1.8 m×1.8 m. The experiment was laid out in Randomized Block Design with eleven treatments replicated thrice. Result indicated that the maximum plant height (260.48 cm), stem girth (46.52 cm), petiole length (80.38 cm), leaf area (1406.15 cm2) and plant spread (193.32 cm) was recorded with T9 (Neem cake + Azotobacter + PSB) application followed by plant height (255.28 cm), stem girth (42.24 cm), petiole length (76.15 cm), leaf area (1388.22 cm2), plant spread (189.49 cm) with T7 (Vermicompost + Azotobacter + PSB) and minimum in control. Observations recorded on yield and yield contributing characters revealed that the fruit length (35.48 cm), fruit diameter (16.22 cm), fruit volume (1272.45 cc), fruit weight (1274.82 gm), fruit yield per plant (58.4 kg), fruit yield per plot (467.2 kg), fruit yield per hectare (72.6 q) was recorded maximum with T10 (Farm yard manure + Vermicompost +Poultry manure + Neem Cake + Azotobacter + PSB) and the minimum values of these characters were recorded T11 under control.
