Guava (Psidium guajava L.) is a perishable and climacteric fruit. The peel surface of guava is soft. During transportation, guava surface is rupture lack of proper packaging. Two types of corrugated fibre board (CFB) cartons of 7 and 5 ply and one type of wooden box were designed and fabricated for transportation of guava in Farm Machinery and Postharvest Process Engineering (FMPE) Division, Bangladesh Agricultural Research Institute, Gazipur in 2013. The dimensions of the cartons were 513 x 300 x 240 mm and 400 x 300 x 300 mm. The 7 ply cartons of both the size were found better than those of 5 ply cartons in terms of static load bearing capacity. The carton of 513 x 300 x 240 mm was better than that of second one. The holding capacities of these cartons were about 18-20 kg of guava. The static load bearing capacities of both the cartons of 7 and 5 ply cartons were 90 and 70 kg, respectively. Green matured guava was harvested, sorted and packed in different packages, such as bamboo basket, wooden box, plastic crate, and CFB cartons. They were transported from Sharupkhati of Barisal to Gazipur by a track. Then the guava packages were opened in FMPE Division, BARI, Gazipur and stored at ambient temperature (28.8 ± 2°C) and humidity (87± 2%) for 8 days. The highest shelf-life of guava was found in wooden box without wrapping and the lowest shelf-life was in CFB cartons with polyethylene (0.05 mm) having 2% perforation. Wooden box was found suitable as packaging material for transportation of guava in terms of freshness, shelf-life, and packaging cost. Packaging cost of CFB cartons was higher followed by that of plastic crate, wooden box, and bamboo basket. Packaging costs of plastic crate and wooden box were cheaper than those of CFB cartons and bamboo basket. Plastic crate and wooden box should be used for local market to transport the fruits. CFB carton may be used for export market or supper market. DOI: http://dx.doi.org/10.3329/bjar.v39i2.20437 Bangladesh J. Agril. Res. 39(2): 337-350, June 2014

<p>Among fruits, guava (<em>Psidium guajava </em>L.), belonging to the Myrtaceae family, grows well in tropical and subtropical regions. It is an important export fruit but it is perishable, so it must be processed into some kind of products like jam, jellies and concentrates. Nutritional and shelf life of fruit based product depend upon number of storage factors as well as pre-harvest factors like soil type, nutrient availability, rainfall, neighbor plants, climate and season. Season is an important pre-harvest factor, affecting the quality attributes of guava products. In present study guava juice concentrate was prepared from fruit harvested in spring as well as in autumn seasons. The results showed that guava concentrate made from autumn fruit had 1.13 times brix content, have higher pH and 3.9 % more vitamin C as compared to concentrate made from spring season guava. The results indicated that the concentrate prepared from guava harvested in autumn season was nutritionally better than the concentrate prepared from guava harvested in spring season.</p>

Subtropical Fruit

Guava (Psidium guajava L.) is a lovely tropical and subtropical fruit that originates in Mexico, Central America, and then taken to other distant and near parts around the world. In Sudan this popular fruit is produced in orchards and household and is so profitable but yet attacked by a lot of fruit fly species of the Genera Ceratitis and Bactrocera and the result is a loss of more than 70%. This research aimed at evaluating the effect of Gum Arabic coating (GAC) in extending the shelf life of guava fruit and disinfesting it from these notorious pests. Guava fruits from Kadaro orchards, Khartoum North, were tested using seven concentrations of Gum Arabic solutions. The results reflect that 1: 4 (25%) and 1: 8 (12.5%) (GA: water) concentrations attained 56 and 40% disinfestation, respectively whereas the other lower concentrations effected corresponding results in a range from 20 – 08%. The reduction in maggots per test fruit reached upto 188% as compared to the control.  The highest concentrations (1: 4 & 1: 8) effected a sustainability of 52% in fruit firmness (FF) with an average of medium (3) FF compared to soft FF (4) in the control. The corresponding results in other lower concentrations (1: 16; 1: 32; 1: 64; 1: 72 & 1: 96) were 36, 24, 24, 20 and 16%, respectively. In addition to an average FF of 4 (soft) for all these concentrations and 5 (very soft) for all the corresponding controls. Nevertheless, the sustainability of fruit color (FC) effected by the test concentrations was 52, 44, 24, 22, 24, 20, and 24%, respectively. Regarding these results, the two highest test concentrations effected a sizeable disinfestation and control of fruit flies and a good extension of shelf life of guava in Khartoum State. These findings support using this treatment as an effective IPM tool to extend guava fruit shelf life and upgrading its postharvest quality.

Background: Bio-fortification, the process of integrating nutrients into food crops, provides a sustainable and economic way of increasing the density of micronutrients in important staple crops. Agronomic bio-fortification is the easiest, practicable and fastest way for bio-fortification of pulse grains with Fe, Zn, or other desirable micronutrients. Increasing micronutrient rich foods and improving dietary diversity will substantially reduce micronutrient disorders.Methods: A field experiment was conducted during the post rainy seasons of 2015, 2016 and 2017 at Zonal Agricultural Research Station, Kalaburagi, University of Agricultural Sciences, Raichur (Karnataka) to know the effect of soil and foliar fertilization of Zn and Fe on chickpea genotypes. Two genotypes (Annigeri 1 and JG 11) and six fertilization treatments (Control, 0.5% Zn, 0.1% Fe, Zn + Fe, seed treatment with 2 g Zn kg-1 seeds and soil application of Zn) were tested in medium black soils in split plot design with three replications.Result: The pooled data of three seasons indicated that the genotype JG 11, performed better than Annigeri 1 in terms of seed yield (1309 kgha-1), net returns (₹ 31634ha-1) and B: C ratio (2.52). On biofortification of Zn and Fe, foliar fertilization of Zn @ 0.5% + Fe @ 0.1% at flowering stage recorded significantly higher grain yield (1321 kgha-1), net returns (₹ 31179ha-1) and B: C ratio (2.44) over rest of the treatments. Further, foliar fertilization of Zn + Fe had significant influence on nutrient concentration (Zn and Fe) in chickpea grains. Thus, it could be concluded that combined biofortification of Zn + Fe to chickpea crop could be the viable agronomic intervention for getting higher productivity and nutritional security.

Ber, a climacteric fruit crop, is liable to spoilage during storage. This study aims to evaluate the effect of coatings on shelf life and quality retention in ber under ambient storage conditions. Coated and uncoated ber fruits were stored at ambient storage temperatures (±25ºC) for 10 days and accessed every 2 days for analysis. Ber fruits reported minimum weight loss (2.68g), PLW (14.35%) and TSS (9.52%) with the application of petroleum jelly coating. Minimum total sugars (8.98%), minimum reducing sugar content (3.96%), maximum non-reducing sugars (5.69%) and maximum antioxidant activity (63.83%) was recorded in fruits with petroleum jelly coating. This study highlights the importance of coating of fruits for enhanced shelf life and quality retention under ambient storage conditions.

Guava (Psidium guajava L.) is a tropical fruit exhibiting rapid post-harvest ripening. However, the physiological basis involved in the ripening process of guava is not totally clear, which makes it difficult to develop technologies to enhance fruit storability. Two experiments were carried out with the objective of determining the ripening behavior of 'Pedro Sato' guavas. In the first experiment, guava fruits at three maturity stages (I - dark green, II - light green and III - yellow-green) were stored at room temperature (23 ± 1°C and 85 ± 5 % RH). The respiratory rate, ethylene production, pulp and skin colours, and firmness were evaluated. In the second experiment, ethylene and 1-methylcyclopropene (1-MCP) were applied to guavas at the light green maturity stage and the ripening behaviour during storage at room temperature was studied. Fruits from all maturity stages showed a gradual increase in the respiratory rate and ethylene production. The intense changes in pulp and skin colours and in firmness preceded the maximum respiratory rate and ethylene production. 1-MCP reduced the rate of ripening, while the application of ethylene did not promote this process. These results do not permit the classification of 'Pedro Sato' guava as a traditional climacteric fruit.

Guava leaves can be used as a natural preservative in quail carcass because they contain antimicrobial compounds such as flavonoid and tannin. This study studied the effect of using guava leaves infusion on quail carcass on the total bacteria, Enterobacteriaceae, and early spoilage.  The research used an experimental method with a completely randomized design, 3 treatments of guava leaves infusion concentration, namely P1 = 25%, P2 = 50%. And P3 = 75%, each treatment was repeated 6 times.  The application of infusion to quail carcass was carried out by immersion for 15 minutes.  Data were analyzed using ANOVA and Turkey’s test.  The results showed that the total bacteria and Enterobacteriaceae before immersion were 3.80 x 107 cfu/g and 1.90 x 104 cfu/g, respectively.  Soaking quail carcass in guava leaves infusion was able to reduce the total bacteria and Enterobacteriaceae to 72.15% and 78.50%, respectively.  The early spoilage was inversely proportional to the total bacteria and Enterobacteriaceae resulted in longer shelf life.

An experiment was carried out at the Regional Agricultural Research Station, BARI, Ishurdi, Pabna during 2013-15, with eleven genotypes of plantain to evaluate their performances for yield attributes, yield and quality characters. The genotypes included in this investigation were MP001, MP002, MP003, MP006, MP007, MP015, MP018, MP024, MP025, ISD002 and BARI Kola-2 as check. The experiment was laid out in randomized complete block design with three replications. The genotype MP002 produced the maximum number of fingers/bunch (105.67) closely followed by BARI Kola-2 (103.00) and MP015 (101.00). Both the genotypes MP024 and MP025 showed the highest fruit length (21.70 cm), but ISD002 gave the maximum fruit girth (16.78 cm), which was statistically similar with that of MP003 (16.30 cm) and MP024 (16.33 cm). The highest yield and the maximum number of hands were produced by the genotype MP024 (47.81 t/ha and (8.33/bunch) followed by MP015 (36.70 t/ha and 6.33/bunch). Fingers of the genotypes required boiling time in the range of 20.00 min (MP001) to 15.00 min (BARI Kola-2). Flesh of all genotypes possesses pleasant aroma except MP002, MP003 and ISD002. Among the eleven genotypes MP001, MP006, MP007, MP008, MP015 and MP024 were found better when cooked as smashed. The genotype ISD002 took the maximum time (467.33 days) to reach the edible maturity stage of fruits whereas MP024 required the minimum (339.00 days). The genotypes MP015 and MP024 performed better than BARI Kola-2 in respect of bunch weight, fruit size, productivity index, yield, sucker production and qualitative characters.Bangladesh J. Agril.

The experiment was conducted at Agronomy Research Field, Bangladesh Agricultural Research Institute, Gazipur during 2010-11 to find out the appropriate planting system of potato and plant density of maize in potatohybrid maize intercropping system for maximum yield and economic return. Ten treatments were evaluated viz., T1= Potato whole tuber single row (75 cm × 20 cm) + 125% hybrid maize (75 cm × 20 cm), T2=Potato whole tuber single row (75 cm × 20 cm) + 100% hybrid maize (75cm × 25 cm), T3= Potato whole tuber single row (75 cm × 20 cm) + 83% hybrid maize (75 cm × 30 cm), T4= Potato half tuber paired row (20 cm/ 55 cm × 20 cm) + 125% hybrid maize (75 cm × 20 cm), T5= Potato half tuber paired row (20 cm/ 55 cm × 20 cm) +100% hybrid maize (75 cm × 25 cm), T6= Potato half tuber paired row (20 cm/ 55 cm × 20 cm) + 83% hybrid maize (75 cm × 30 cm), T7= Sole potato whole tuber single row planting system (60 cm × 25 cm), T8 = Sole potato half tuber paired row (20 cm/ 55 cm × 20 cm), T9= Sole hybrid maize in normal spacing 75 cm × 25 cm (sole HM1) and T10= Sole hybrid maize (75 cm × 25 cm) sown 30 days after potato planting (sole HM2). The results revealed that sole planting of both potato and maize produced the maximum yields. In case of sole potato, potato half tuber paired row planting system was better than potato whole tuber single row planting system. On the other hand, the performance of sole HM1 was better than sole HM2 in relation to growth, yield and economic performance. Over all T1 treatment ( potato whole tuber single row planting system with 125 % hybrid maize population) was the best intercropping system for getting higher yield and economic return as well as less relative crowding coefficient with better crop performance ratio.Bangladesh J.

Abstract In the era of globalization, policy makers in both developing and developed countries have sought to expand their export destinations, with the expectation that export market diversification can boost export upgrading and economic development. Although extant literature has confirmed that exporters search for new markets in two distinct ways: direct search underpinned by the gravity effect and remote search driven by the extended gravity effect, it has not advanced very far due to the lack of adequate measures of those effects. This article presents a technique that uses available export data to develop measures of those two effects that capture a larger range of factors and thus allow us to more easily predict export market diversification. Our new indicator also simplifies the prediction by combining gravity and extended gravity effects. Empirical results show that the explanatory and predictive power of our new method is better than that of the traditional one based on gravity and extended gravity models.
