Abstract

Of late growing awareness on health makes consumer more concerned for food quality and safety. In banana
Total soluble solids, acidity and sugar content mostly determine the degree of acceptability of fruit. An experiment
was conducted during 2010-11 with 12 different treatment combinations of Farmyard manure, Vermicompost, Neem
cake, Wood ash and green manures (organic sources) along with and without microbial inoculants (Arbuscular
mycorrhizae, Azospirllium, Phosphate solubilising bacteria and Trichoderma harzianum) comparison with inorganic
sources alone on quality attributes and shelf life of banana cv. Grand Naine (AAA). Results revealed that the
treatment T10 (Farmyard manure @ 10 kg + Neem cake @ 1.25 kg + Vermicompost @ 5 kg and Wood ash @ 1.75
kg /plant + Triple green manuring with sunhemp + Double intercropping of Cow pea + biofertilizers viz., Vesicular
Arbuscular Mycorrhizae @ 25 g, Azospirillum @ 50 g, Phosphate solubilizing bacteria @ 50 g and Trichoderma
harzianum @ 50 g/plant) registered the maximum quality attributes (TSS – 23.23%, Acidity – 0.82%, Ascorbic acid –
12.92 mg. 100 g -1, Non-reducing and Total sugars - 6.06 and 14.92%) besides enhancing the shelf life of banana
(14.03 days) and reduced physiological loss in weight (7.44%).

Introduction

Banana (Musa sps.) is the most important fruit crops of the world. It has nutritional, medicinal, industrial as well as aesthetic value in Hindu religion. Out of the large number of varieties grown in India, Grand Naine is the popular variety grown mostly in all export oriented countries of Asia, South America and Africa. It is a superior selection of Giant Cavendish which was introduced to India in 1990’s. Due to many desirable traits like excellent fruit quality, immunity to fusarium wilt etc, it has proved as a better variety [1]. The quality attributes of ripe fruit are mainly influenced by the genotype, the nutritional status of the soil also plays a significant role [2]. Continuous use of inorganic fertilizers as source of nutrient in imbalanced proportion is also a problem, causing inefficiency, damage to the environment and in certain situations, harms the plants themselves and also to human being who consumes them. Some studies have suggested that organic manures gave better quality and post-harvest life of fruits when comparing to inorganic sources of nutrients in banana [3]. Many investigators studied the combined application of organic manures and amendments can enhance the yield, quality and post-harvest attributes of fruit crops Patel et al. [4] in banana and Akash Sharma et al., [5] in Guava. Organic manures contain macro and micronutrients, plant growth promoting substances like auxins, gibberellins, and cytokinins [6]. However, information regarding the type of organic manure, their optimum dose, and their interaction with bio fertilizers on different quality attributes and shelf life of banana is sketchy. With this background the present study was conducted to determine the impact of different doses of organic manures, amendments and their combinations on important quality attributes and post-harvest life of banana.
 
Materials and Methods

The present investigation was carried out at Horticultural College and Research Institute, TNAU, Coimbatore, during the year 2010-11 with banana (Musa spp.) cv. Grand Naine (AAA). The experiment was laid out in a Randomized Block Design with twelve treatments and four replications. The treatments comprised of organic manures, amendments and green manures viz., FYM @ 10 kg/plant + Neem Cake @ 1.25 kg/plant + Vermicompost @ 5 kg/plant and Wood ash @ 1.75 kg/plant (T1), FYM @ 10 kg/plant + Neem Cake @ 1.25 kg/plant + Vermicompost @ 5 kg/plant and Wood ash @ 3.75 kg/plant (T2 ), FYM @ 15 kg/plant + Neem Cake @ 1.875 kg/plant + Vermicompost @ 7.5 kg/plant and Wood ash @ 625 g/plant (T3), FYM @ 15 kg/plant + Neem Cake @ 1.875 kg/plant + Vermicompost @ 7.5 kg/plant and Wood ash @ 2.625 kg/plant (T4), Control - absence of organic and inorganic sources (T5), Triple green manuring with sunhemp + Cow pea + Cow pea as inter - crop (T6), Arbuscular Mycorrhizae @ 25 g/plant + Azospirillum @ 50 g/plant + PSB @ 50 g and Trichoderma harzianum @ 50 g/plant (T7), T1 + T6 (T8), T1 + T7 (T9), T1 + T6 + T7 (T10) and the absolute control treatments (inorganic) 300 : 100 : 300 g NPK /plant (T11), 110 : 35 : 330 g NPK /plant (T12).

The recommended spacing of 1.8 m×1.8 m was adopted for planting of banana cv. Grand Naine obtained from organic field. Among the twelve treatments, ten treatments were organic treatments (Nutrients equal to the recommended dose of inorganic fertilizers) supplied through organic manures and amendments (FYM and Neem Cake were applied as basal dose, Vermicompost, Vesicular arbuscular mycorrhizae, Azospirllium, Phosphate solubilizing bacteria and Trichoderma harzianum were applied after three month of planting and Wood ash was applied after five month of planting) and rest of them were inorganic treatments with three levels of inorganic fertilizers were applied at 3rd , 5th and 7th month after planting of suckers. Drip irrigation was provided to the experimental plots depending on soil moisture availability. Recommended cultural practices (except nutrient management) and plant protection measures were carried out regularly.
 
Estimation of important quality traits

Fully matured representative fingers were allowed for natural and uniform ripening. These fruits were subjected for determining the quality biochemical parameters. The total soluble solids were determined by using Carl-Zeiss hand refractrometer and expressed in per cent. Titrable acidity was estimated by adopting the method of A.O.A.C [7]. (1960) by titrating against N/10 KOH using phenolphthalein indicator and expressed in terms of percentage of citric acid. Ascorbic acid content was estimated using 2,6-dichlorophenol indophenol dye and expressed as milligrams of ascorbic acid 100 g-1 [8]. Total, reducing and non-reducing sugars were estimated as per the method suggested by Somogyi [9].
 
Estimation of post-harvest characteristics

Shelf life of the fruit was estimated by days taken for the fruits to loose their edible quality as evident by over softening and onset of decay was taken and expressed in number of days. Physiological Loss in Weight (PLW) was assessed by taken Initial weight of the fruits in different treatments were recorded and the final weight was taken as and when the fruits reached the stage of yellow flecked with brown, in each treatment. Physiological loss in weight of fruits was computed at the end of full ripening stage by weight/weight basis by adopting the following formula and the value expressed in percentage.


 
Results and Discussion

Effect of different organic manures and amendments on quality of banana

The fruit quality parameters like TSS (23.23%), total sugars and non-reducing sugars (14.92% and 6.06) and ascorbic acid (12.92 mg. 100 g-1) contents were registered highest values in plants treated with organic amendments as compared to the inorganic treatments (Table 1), due to the better role of nutrients which is involved in the carbohydrate synthesis, breakdown and translocation of starch, synthesis of protein and neutralization of physiologically important organic acids. These findings are in concordance with the results of Anon [10] in Sapota, Anon [11] in custard apple; Pereira and Mitra [12] in guava and Athani and Hulamni [13] in banana and reported that the increased fruit quality parameters are due to the addition of different organic manures and amendments to the soil and in turn to plants, which might had enhanced the biosynthesis and translocation of carbohydrates in to fruits. Further, the availability of nitrogen from different sources might have increased leaf area with higher synthesis of assimilates which is due to enhanced rate of photosynthesis. Such effects have been attributed to increase rate of translocation of photosynthetic products from leaves to developing fruits and thereby increasing total sugars [14-17].
 
Effect different organic manures and amendments on post-harvest characters of banana

Shelf life of banana is an important parameter and influenced directly by the pre harvest nutritional status of the fruits. The influence of nutrients derived from organic sources had a positive effect on the post-harvest characters of banana (Table 1), the highest shelf life (14.03 days) of fruits and least physiological loss in weight (7.44 per cent) were observed in the treatment T10. On the other hand, the shelf life of the fruits was minimum (9.73 days) and physiological loss in weight was maximum in T5 (12.05 per cent) next to T6 (13.23 per cent). The extended shelf life observed in the present study might be due to the consequence of reduced weight loss and other physiological process like reduced respiration and transpiration. This result lends support to the findings of Athani and Hulamni [13] in banana.
 
Conclusion

Substitution of organic manures and amendments (biofertilizers and biocontrol agents) and green manures combination significantly enhanced the important quality attributes and post-harvest life of banana compared to either organic manure alone or inorganic sources alone.
