Abstract

An experiment was carried out to study the effect of denavelling and bunch feeding of nutrients on banana cv. Champa (AAB) at the AICRP on fruits, Horticulture Research Station, Odisha University of Agriculture and Technology, Bhubaneswar during the year 2020. The results revealed that denavelling of bunch with supplementation of bunch feeding significantly influence the yield and quality of banana. The Maximum value in respect of T.S.S. (22.140B), reducing sugar (16.11 %), total sugar (20.72 %), non-reducing sugar (4.61%), ascorbic acid (5.35 mg / 100 g) and minimum acidity (0.25) were observed with T5 (Denavelling + bunch feeding of cow dung slurry with K2SO4 @15g/plant). Whereas, pulp characters of finger like pulp weight (75.25 g), peel weight (15.36g), pulp to peel ratio (4.97) and yield (34.53t/ha) were noticed maximum in T5 which is followed by T4 (Denavelling + bunch feeding of cow dung slurry with K2SO4 @7.5g/plant). The economic analysis of the study indicated that the maximum gross return (Rs. 6,90,600/-, net return (Rs. 4,54,650/-) and B:C (2.920 was realised in the treatment T5 (Denavelling + bunch feeding of cow dung slurry with K2SO4 @15g/plant) as compared to T1: control. Hence, the results clearly indicated that denavelling along with bunch feeding is a viable proposition for enhancing the productivity, quality and profitability of banana cultivation.

Conclusion

The direct application of nutrients to plants through distal stalk end feeding is important post-shoot bunch management practices to increase the yield. The results showed that a robust relationship exists between the quantity of SOP used and the expected increase in yield. The present study clearly indicates that the practice of denavelling along with combined application of cow dung slurry and K2SO4 @15g/plant to the banana bunch proved to be the best in pulp characters as maximum recorded in weight (75.25 g), peel weight T5 (15.36g), pulp to peel ratio (4.97), yield (34.53t/ha) and quality as recorded maximum T.S.S. (22.140B), reducing sugar (16.11 %), total sugar (20.72 %), non-reducing sugar (4.61%), ascorbic acid (5.35 mg / 100 g) and minimum acidity (0.25) T.S.S. (22.140B), reducing sugar (16.11 %), total sugar (20.72 %), non-reducing sugar (4.61%), ascorbic acid (5.35 mg /100 g) and acidity (0.25) T.S.S.(22.140B), reducing sugar (16.11 %), total sugar (20.72 %), non-reducing sugar (4.61%), ascorbic acid (5.35 mg / 100 g) and acidity (0.25) for improving the uniformity in bunch and fruit nutrient status which in turn helps to increase the total yield and higher net return and B:C ratio (2.92).
