  • Model Profile for 1.0 Ha Mango Cultivation
    Model Profile for 1.0 ha Mango Cultivation 1. Introduction Mango (Mangifera indica) is the leading fruit crop of India and considered to be the king of fruits. Besides delicious taste, excellent flavour and attractive fragrance, it is rich in vitamin A&C. The tree is hardy in nature, can be grown in a variety of soil and requires comparatively low maintenance costs. Mango fruit is utilised at all stages of its development both in its immature and mature state. Raw fruits are used for making chutney, pickles and juices. The ripe fruits besides being used for desert are also utilised for preparing several products like squashes, syrups, nectars, jams and jellies. The mango kernel also contains 8-10 percent good quality fat which can be used for soap and also as a substitute for cocoa butter in confectionery. 2. Scope for Mango Cultivation and its National Importance Mango occupies about 36% of the total area under fruits (2010-11) comprising of 22.97 lakh hectares, with a total production of 151.88 lakh tonnes. Uttar Pradesh and Andhra Pradesh are having the largest area under mango each with around 23% of the total area followed by Karnataka, Bihar, Gujarat and Tamilnadu. Fresh mangoes and mango pulp are the important items of agri-exports from India. India's main export destinations for mango are UAE, Bangladesh, UK, Saudi Arabia, Nepal, Kuwait, USA and other Middle East countries with a limited quantity being shipped to European market. Although, India is the largest mango producing country, accounting about 45% of world production, the export of fresh fruit is limited to Alphonso and Dashehari varieties.

  • Changes in the Sensory Characteristics of Mango Cultivars During the Production of Mango Purée and Sorbet
    DIFFERENCES IN SENSORY CHARACTERISTICS AMONG VARIOUS MANGO CULTIVARS IN THE FORM OF FRESH SLICED MANGO, MANGO PURÉE, AND MANGO SORBET by CHRISTIE N. LEDEKER B.S., University of Delaware, 2008 A THESIS submitted in partial fulfillment of the requirements for the degree MASTER OF SCIENCE Interdisciplinary Food Science Graduate Program Department of Human Nutrition KANSAS STATE UNIVERSITY Manhattan, Kansas 2011 Approved by: Major Professor Dr. Delores H. Chambers Abstract Fresh mangoes are highly perishable, and therefore, they are often processed to extend shelf-life and facilitate exportation. Studying the transformation that mango cultivars undergo throughout processing can aid in selecting appropriate varieties for products. In the 1st part of this study, the flavor and texture properties of 4 mango cultivars available in the United States (U.S.) were analyzed. Highly trained descriptive panelists in the U.S. evaluated fresh, purée, and sorbet samples prepared from each cultivar. Purées were made by pulverizing mango flesh, passing it through a china cap, and heating it to 85 °C for 15 s. For the sorbets, purées were diluted with water (1:1), sucrose was added, and the bases were frozen in a batch ice cream freezer. Much of the texture variation among cultivars was lost after fresh samples were transformed into purées, whereas much of the flavor and texture variation among cultivars was lost once fresh mangoes and mango purées were transformed into sorbets. Compared to the other cultivars, Haden and Tommy Atkins underwent greater transformations in flavor throughout sorbet preparation, and processing reduced the intensities of some unpleasant flavors in these cultivars.

N. PATEL AND V. R. MALAM Department of Horticulture, College of Agriculture, JAU, Junagadh email : [email protected] ABSTRACT In high tree density situations with closer spacing, it To reduce the plant height and tree with a compact growth is recommended to apply paclobutrazol early when trees for easy agronomical practices, synchronized flowering are about three years old. When trees are spaced at 10 m, and maturity in the orchard are of prime priority for the early application with paclobutrazol will reduce canopy size and the fruit bearing area. In such a situation, treatment growers and researchers. Irregular and alternate bearing in fruits is a major problem faced by fruit growers. Plant can commence when trees are about five years old. In dry height, flowering, yield and quality including alternate conditions, a light irrigation is recommended after bearing can be overcome by various horticultural practices application. Paclobutrazol applied soon after harvesting in like pruning, thinning of fruits, use of chemicals like older tree. The application of paclobutrazol to soil as a Paclobutrazol etc. out of these use of Paclobutrazol is drench around the tree trunk (collar drench) is the most commonly practiced by the horticultural growers. The soil effective method. The required quantity is mixed in application of paclobutrazol is effective to restrict vegetative approximately 1 L of water and poured onto the soil around growth, early flowering, increase yield and improve quality.

Similarly application of PBZ recorded 242.4, 163.1 and 52.8 per cent more number of fruits per tree, 13.4, 14.8 and 26.1 per cent decline in average fruit weight, and 171.2, 180.0 and 49.3 per cent higher yields than control trees of Raspuri, Dashehari and Amrapali respectively, when compared to control. Among the interaction effects, trees pruned to current season’s growth and with PBZ application recorded significantly higher fruit number (143.7) and higher yileds per tree (28.1 kg). Raspuri and Dashehari trees pruned to current season’s growth recorded high TSS (20.13 and 20.16 °Brix, respectively) compared to control trees (P3). Similarly, trees without PBZ application (C2) recorded higher TSS of 19.89 and 21.25 °Brix in cvs Raspuri and Dashehari, respectively. PBZ application recorded significantly higher ascorbic acid and carotenoid contents in Dashehari and Amrapali cultivars.

Hada Article ID: AR1811a e-mail: [email protected] Received in 3rd May, 2017 Received in revised form 29th June, 2017 Accepted in final form 4th August, 2017 Abstract A field experiment was conducted to investigate the flowering, fruiting and yield attributes of some mango cultivars for the years 2014−15 and 2015−16. Outcome of the present research work revealed that the date of panicle emergence in different mango cultivars varied in both the years. It was observed that the panicle emergence was earliest in Gulabkhas and late in Fazli in both the years. Chausa produced maximum panicle length (35.19 cm) and breadth (24.76 cm). In the year 2014−15, earliest flowering was noted in Gulabkhas (Feb 17−Feb 26) and in the year 2015−16, earliest flowering was observed in Bombai (Feb 20−Feb 28) while, flowering was very late in Sepiya for both the years. Maximum number of flowers was observed in Langra (1839.13) while, minimum number of flowers was recorded in Amrapali (954.75). The duration of flowering varied from 22.50−36.00 days in different mango cultivars. Maximum value in terms of days was observed with Sepiya (39 days) while it was minimum (22.50 days) in case of Alphonso.

A Study on Bio-chemical Characteristics of Different Mango Germplasms Grown in the Climatic Condition of Mymensingh. Int. J. Sustain. Crop Prod. 1(2): 16-19. An investigation on some bio-chemical characteristics of twenty two mango germplasms namely, Rad, Farooquebhog, Neelumbori, Neelumboti, Chausa, Mallika, Tommy Atkin, Hybrid-10, Shindhu, Mixed special, Gopalbhog, Surmai Fazli, Langra, Khirsapat, Amrapali, BARI mango-1, Kent, Keitt, Palmar, Kalibhog and Sindhu was carried out at the Germplasms Center of Fruit Tree Improvement Project, Department of Horticulture, Bangladesh Agricultural University, Mymensingh during December, 2002 to December, 2003. All the germplasms were chemically analysed and highly significant differences were recorded among the germplasms. Farooquebhog possessed maximum moisture content whereas Mixed special had the highest titratable acidity. The germplasms Pahlam was top in the list in case of TSS and pH but Rad and Amrapali was also top in respect of reducing sugar and non-reducing sugar, respectively. On the other hand, maximum total sugar and sugar/acidity ratio were noted in Rad and Amrapali, respectively.

Preface Tropical fruits are abundant source of nutrients and bio-active compounds that provide numerous health benefits and have been proven in many scientific studies. In today’s fast moving society and ever changing food habit of consumers have led to the development of natural food products to fulfill not only the nutritional needs but also product specifications demanded by consumers. This e-book aims to present the latest research works carried out by researchers worldwide for drying and preservation of tropical fruits ranging from the very common (e.g. mango, pineapple) to the more exotic selections (e.g. ciku, durian, dragon fruit). By converting fresh tropical fruits into dried products via advanced drying/dehydration techniques, this helps to provide an alternative choice of healthy fruit snacks especially to consumers residing outside tropical climate regions.
