Collection trips were organized in a planned manner so as to cover every locality in all three seasons. Rural and remote areas which were thus far practically unexplored were surveyed more intensively. Frequency of collection trips was twice a week during first year; once a fortnight in third and once a month in the last and forth years. During the field work, observations on the habit and habitat; flower colour; fragrance; fruiting, colour of the bark and blaze in case of trees and shrubs; dominance and sociability of the collected plants were entered into rough field book. In the mean time information regarding medicinal or other uses, if any, were gathered from local inhabitants, vaidyas and haquims. Plants of small size were uprooted carefully and pressed as such. In case of larger plants, care was taken so that specimens should have flowers, fruits, leaves and stems of young and old stages. At least four specimens, for making herbarium sheets, were pressed at spot after tagging; and a tagged bundle of a few plants was taken in a polythene bag for study in laboratory.

The publication of “Flora of British India” by Hooker (1872-1897) was followed by a series of regional floras by Cooke (1901-08) for Bombay presidency; Prawn (1903) for Bengal: Duthie (completed by Parker & Turrill, 1905-29) for upper gangetic plains and adjacent Siwalik and of sub Himalayan tracts; Kanjilal (1966) for the forest flora of Uttar Pradesh; Gamble (completed by Fisher, 1915-1936) for Presidency of Madras; Haines (1921-1925) for Bihar and Orissa: and Kanji et al (1934-1940) for Assam. Duthie’s work was completed by Raizada and associates (Raizada, 1954, Raizada et al. 1961; 1983; Raizada & Jain, 1964, 1966). Later, Raizada (1976) brought together all additions made to Duthie Flora. However, the trends of additions has persisted afterwards and is hoped to continue onwards as well. Revision of old floras has become all the more important because the nomenclature of a large number of species has changed in accordance with International Code of Botanical Nomenclature (1956, 1961, 1966, 1972, 1978 & 1983).

India has a very wealthy tradition of herbal medicines for the treatment of many health discomforts.The tradional healing practicese are common and popular among all the tribes and communities.It is evident that many communities have so much belief in their ethnobotanical knowledge that they often prefer a traditional medicineal practicener over any certified medical personality. Among all the plant species which have been already reported by many researchers for their ethno medicinal properties are getting very rare in their original habitat.These plants are obviously of great medicinal importance and immediate need of conservation.Some medicinal plants which are exclusively found in forest are getting lost due to habitat fragmentation and enormous deforestation.

Oil palm is a major source of edible oil globally and plays a crucial role in meeting the dietary needs of millions of people. India has been focusing on expanding oil palm cultivation to reduce its dependence on imported edible oils. Oil palm can yield high oil compared to other vegetable oils. Palm oil production rate depends on post-harvest handling, and milling and extraction processes. After harvesting, some quality changes occur in oil palm fresh fruit bunches which leads to reduce the oil quantity and quality. With proper handling of post-harvest bunches and adapting best extraction methods can increase the oil yield and quality. Palm oil alone has the potential to make India sustainable in edible oil production.

Introduction

Oil palm (Elaesis guineensis Jacq.) originated in the tropical rain forest of western Africa and is now being cultivated in more than 45 countries around the world especially tropical regions i.e., Malaysia, Indonesia, Thailand, Nigeria, Columbia, and Ghana. This crop was introduced in India during the early 1990s, to meet the demand and to attain sustainable edible oil production in India due to its high oil-yielding capacity compared to other vegetable oil crops. It produces two distinct oils, i.e., palm oil and palm kernel oil. Palm oil is derived from fleshy mesocarp of the fruit and palm kernel oil obtained from the kernel of stony seed.

Coconut, arecanut and palmyrah, which hold significant cultural and historical importance in India, have been the primary focus of cultivation efforts. Cocoa, a relatively recent addition to India, serves as a companion crop to coconut and arecanut, contributing to the economic well-being of farmers nationwide. However, the current situation emphasizes the crucial role of value addition and product diversification in stabilizing prices. Despite the initial stages of value addition in India’s palm crops, recent innovations and established value chains have the potential to empower farmers as entrepreneurs, thereby augmenting their income. Moreover, the value-added products from these palms have enormous export potential. This chapter explores the advancements in value-added products and the diversification of coconut, arecanut, palmyrah, and cocoa, providing insights into opportunities for cottage or small-scale industries.

Introduction

Agricultural production is necessary to fulfil nutritional requirements for human populations and global food security. The agricultural sector also forms the economic backbone of many low-income countries in which millions of farmers are employed (Anushka et al, 2022). However, managing agricultural production to achieve multiple objectives of providing food, supporting livelihoods and protecting biodiversity and forests is a challenge especially in tropical, low-income countries (Anushka et al, 2022). Usually, the growth in global agricultural production is largely driven by commercial and export oriented commodities. One such agricultural commodity that has high global demand is cashew (Anacardium occidentale L.). Cashew is presently cultivated in 33 countries including India in the world. Global land area for cashew cultivation between 1980 and 2018 has seen an eleven-fold increase from 526,250 ha to 5,972,724 ha (Anushka et al, 2022).

Introduction

India is bestowed with huge production of fruits, vegetables, cereals, millets, sugarcane along with meat production, milk production, fish production and poultry. Despite such a huge production in India, owing to perishable nature of these produce around 25-30 per cent of the produce is being lost as post harvest loss. The one important reason for this may be the production of the crops are season specific and during the peak season the production is more while demand for consumption is less. It may be possible to cut down losses to great extent, if these produces may be transported from the produce states to those who are not producing due to agro-climatic reasons. So for making transportation of the perishable a successful venture in decreasing post harvest loss, there must be proper storage facilities both at producing site as well as marketing place. The aim of the storages must be to keep the produce in saleable condition during entire storage periods. Some products are stored for short period whereas fresh fruits, vegetables require cold storage. Foods before keeping into the storage room need some pre-storage treatments for better results.

India is the second largest producer of fruits However, the export potential of fruits and vegetables is very negligible. This is because of improper knowledge to the farmer about proper post-harvest infrastructure facilities. Fruits have a high-water content ranging from 70-95 per cent. They dry quickly under any normal atmospheric condition. These causes loss of rigidity and shrinkage of the cells cause wilting and shrivelling. Appropriate packaging ensures prolonged the shelf life of fruits and vegetables by preventing moisture loss and thereby wilting. Transportation is a critical phase in the fruit supply chain that can significantly affect the quality of fruits. Several factors during transportation can lead to quality degradation such as temperature/humidity fluctuations, mechanical damage, transit time etc. To mitigate the adverse effects of transportation on fruit quality, best practices ie, real-time monitoring, temperature and humidity control, loading/unloading techniques can be employed. Quality evaluation is a critical component in the fruit industry, encompassing a range of assessments to ensure fruits meet the desired standards for consumer satisfaction, shelf life, regulatory compliance, and market competitiveness. It involves a comprehensive approach that includes physical, chemical, and sensory assessments, supported by advanced technological tools, to maintain and enhance the quality of fruits throughout the supply chain. This book chapter deals with the effective packaging, transportation, and quality evaluation of fruits, ensuring that consumers receive fresh, high-quality produce.

The production of fruit crops is largely dependent on the environmental conditions and nutritional status of the plants. Any alteration in the environmental conditions and nutritional status may results in different physiological disorders which affect the growth of the plants and also the quantity as well as quality of the fruits. The precise and early recognition of physiological disorders is important for the timely adaptation of remedial strategies to reduce the crop loss. Physiological disorders in fruits crops may be due to single factors or multiple factors may be involved in the appearance of physiological disorders. A sound knowledge about the cause of physiological disorder is useful to adopt suitable remedy for the disorder.

Introduction

The abnormal growth behavior or unusual external and/or internal conditions of fruits which results due to adverse environmental conditions and nutritional imbalances are considered as physiological disorders. Physiological disorder is best defined as external or internal malfunctioning resulting from improper environmental or cultural conditions before and/or after harvest. Variation from normal temperature, light, moisture, nutrient, harmful gases, insufficient supply of growth regulators, deficiencies or excesses of nutrient etc. are some of the important environmental and cultural factors of physiological disorders (Fig. 1). Physiological disorders affect the quality as well as quantity of the fruit crops. Detection of precise physiological disorders is not easy and requires a strong knowledge regarding them.

Introduction

Fresh fruit journey from the farm to the consumer’s table is an intricate process which needs a lot of attention. The way that the produce is harvested and handled is of supreme importance in relation to its quality shelf life and general market attractiveness. Improper handling practices during these critical stages can bring both quantitative and qualitative loses hence the perishable produce will lose its commercial value and appeal to the consumers (Kader, 2005). No doubt the significance of successful harvesting and post-harvest handling practices is crucial and has an impact on quality features and safety in case of fresh fruits. Poor management can cause physical assault ripening speed and more susceptibility to the growth of micro-organisms which makes the produce unsuitable for consumption or processing.

Horticulture sector, comprising fruits, vegetables, floriculture, medicinal and aromatic crops, mushroom, spices and plantation crops, had witnessed phenomenal growth in production and productivity during the last two decades. Resultantly, horticulture in India is recognised as one of the fastest growing sectors in the world. The production has reached to 351.92 million tonnes in 2022-23 as compared to 231 million tonnnes in 2010. Progressive urbanization, increased spendable income and awareness for balanced and nutritious food have contributed towards increasing demand of horticulture produce. The increasing demand coupled with higher income returns per unit area has triggered this growth pattern, which has been largely possible due to policy environment to support horticulture both for research and development.

Fruits represent a vital component of global agriculture, serving as not only a significant source of essential nutrients but also a lucrative sector of the economy. However, from the moment of their inception on the tree to their arrival on consumers’ tables, fruits undergo a complex journey influenced by a myriad of factors. Among these, pre-harvest practices wield a profound impact on fruit quality, enzymatic activities, texture, ripening, and ultimately, post-harvest transportation losses. Each pre-harvest practice, from mineral nutrition to harvesting methods, plays a distinct role in shaping the biochemical composition and physical attributes of fruits, ultimately affecting their marketability and shelf life. Mineral nutrition stands as one of the foundational pillars of fruit production, with essential minerals serving as building blocks for various biochemical processes. Irrigation practices represent another critical aspect of pre-harvest management, as water availability profoundly impacts fruit development and composition. Different irrigation regimes can influence enzymatic activities, fruit texture, and the timing of ripening, necessitating strategic water management to achieve desired fruit quality while minimizing post-harvest losses. Canopy regulation, achieved through training and pruning techniques, offers growers a means to manipulate light penetration and airflow within the orchard. Moreover, the application of plant growth regulators (PGRs) emerges as a tool for fine-tuning fruit development and ripening processes. By modulating hormonal signals, PGRs can alter enzymatic activities, influence fruit texture, and mitigate transportation losses. However, judicious application is paramount to avoid adverse effects on fruit quality and safety. Harvesting decisions, including the determination of optimal maturity and the timing and method of harvest, profoundly impact fruit quality and post-harvest losses.

Horticulture crops contribute significantly for the total agricultural production and productivity. World production of fruits accounted for the total volume of 933 million tonnes (FAO, 2023). India being second largest producer for majority of fruit commodities had a production total reaching 108.34 million tonnes in 2022-2023 from an area of 7.15 million hectares. It accounts for 33 per cent to the agriculture GVA (Gross Value Added) and plays an important role in the Indian economy. India is second largest producer of majority of fruits and vegetables. Diverse agro-climatic zones in the country make it possible to grow almost all varieties of fruits in India. Produced fruits are used for domestic consumption, processing and export purposes. During 2022 23, fresh fruits exports was valued at 6219.46 crores (APEDA, 2023). The fruits grown in India includes domestic fruits and nuts along with the exotic fruits contributing for the food and nutritional security. The growth of these economically important fruits provides scope for maintaining rich germplasm, enhance bio-diversity and maintain ecological balance.

Fruits are an important supplement to the human diet, as they provide minerals, vitamins and fiber required for maintaining good health. Fruits are also rich in phytochemicals (7, xanthophylls, polyphenols, flavonoids, phenolic acids, organic acids etc.) which possess good antioxidant properties. India’s diverse climatic conditions ensure availability of almost all the varieties of fresh fruits and vegetables. According to FAO (2021), the country ranks first in the production of bananas (26.45%), mangoes (including mangosteens and guavas) (43.80%) and papayas (39.30%). The scenario of horticulture crops in India has become very encouraging. The percentage share of horticulture output in agriculture has become 33 per cent (Anonymous 2021). India has witnessed increase in horticulture production over the last few years. Significant progress has been made in area expansion resulting in higher production. Over the last decade, the area under horticulture grew by 2.1 per cent per annum and annual production increased by 3.9 per cent. During 2020-21, the production of horticulture crops was 334.60 million tonnes from an area of 27.74 million hectares. The production of fruits has increased from 76.42 million tonnes in 2011-12 to 108.34 million tonnes in 2022-23 (Agricultural Statistics at a Glance 2022). The area under cultivation of fruits stood at 7.05 million hectares. The total production of fruits in the year 2020-21 was highest in case of Andhra Pradesh (17.70 million tonnes) followed by Maharashtra (11.73 million tonnes) and Uttar Pradesh (11.23 million tonnes) (Anonymous 2021). India now is the second largest producer of vegetables and fruits in the world. The country ranks at first position in the production of banana, mango, lime and lemon, papaya and okra. The area and production of fruits in India is presented in Table 1. The fruits namely banana, mango, citrus, papaya, guava, grapes, apple, pineapple and sapota account for more than 85 per cent of the total production of fruits. The other fruits which are produced in India are almond, walnut, jackfruit, bael, ber, custard apple, kiwi, passion fruit, peach, pear, plum, strawberry etc.

Introduction

A number of experts have recognised three different stages in the march of man on the earth. These consist of: (i) When the civilization is dominated by the forests, (ii) When the civilization is overcoming the forest and (iii) When the civilization is dominating obstacles caused by forests. Now a days, Indian Himalayas including that of Jammu and Kashmir is passing through the third stage i.e., to the point of destroying itself in the process.

Deforestation’s relentless march is stripping the Jammu and Kashmir Himalayas bare of its forest cover. From the majestic coniferous forests of Pir Panjal Himalayas to the deciduous and mixed canopy of subtropical forests the story is tragically the same i.e.. the indiscriminate destruction of forests that could turn the state into vast and inhospitable waste land. Hence to sustain and prosper the civilization, the forests must be saved from being further destroyed.

To reduce or to minimize the deforestation, the Social Forestry Project and Agroforestry System came to fore. The primary objective of Social Forestry is to increase supplies of fuel wood and fodder in rural area through plantation on community waste lands, degraded forest lands and on private lands through farm forestry (Patnaik, 1995-96). The latter i.e., Agroforestry is now much more widely used subject than the mere production of wood and food. In the changing scenario of the environmental degradation and ecological imbalance as a result of degradation of the forest resources of the country, agroforestry consists of inviting the prime attention of forests for upliftment of both environment and ecology vis-a-vis to enhance agricultural/horticultural and livestock production. In fact, agroforestry came as a new’ name during the year 1978. Since then, the Indian Council of Agricultural Research (ICAR), New Delhi, has developed a vast network of agroforestry in all 36 centres of Agroclimatic Zones (Tejwani, 2008). However, Dr Tejwani started working with agroforestry during 1957 on fodder fuel plantations and trees on farm boundaries. Hence, agroforestry must be included in the agriculture.

Introduction

Since 2001, India’s human beings population has crossed 1000 million, which is presently 1361 million and will became more than 1462 million during 2025. Such a large population of human beings can be fed and clothed only if we make the best use of the country’s land and water resources. While water is replenishable natural resource. Contrary to this, the land is a non-renewable and irreplaceable resource. It, therefore, becomes an imperative to think of about the main problems of protecting/preserving and managing the land resources f irst of all and thereafter managing the water resources. Such an approach will, infant, prove a solution of both of these resources. It is because if the land of the country is looked after properly, the problem of water management would be automatically tackled (Singh, 2007)

Out of the total land area of India, about 329 million hectares (m ha) as many as175 m ha suffer from degradation, caused for the most part by the soil erosion, water logging, soil salinity and sodicity as well as acidity. This denotes that on an average at least two out of every 3 acres (1.2 ha) of land is in poor condition. It is also known that at least half of the sick land i.e., one third of the total is almost completely unproductive. Another one third is partially productive and it is only the remaining one third is in good health.

Introduction

The Indian literature viz; Vedas and other related books show that ancient Indians used to impart great significance to the gardens and parks. Indian rulers especially, the kings, the princess vis-a-vis affluent people took special interest in making vegetable gardens in the houses and fruit tree gardens in open areas. In those days, it was considered to be the foremost duty of a king to maintain the beautiful gardens in the city and around his palace. It is even said that only he should be revered as an ideal king whose abode is provided with spacious gardens having full of fruit bearing trees (Krishna murthy 2012). As a matter of fact, the gardens also contained pools and tanks adorned with beautiful lotus blossoms, having a number of plants and bushes laden with large number of fragrant flowers etc. Kautilya has included gardens and fields under the term of “Vastu”. So Vastu Sastra or the science of habitation may be taken to stand for laying out of gardens etc; including both horticulture and agriculture.

Pulses are an important source of proteins. One hundred grams of pulses contain about 25-32 grams of proteins and several amino acids which are not made by the human body (Sidhu, 2015). These are the staple food both for vegetarians and non-vegetarians of the country. India is not only the largest consumer of the pulses in the world but it is also the largest producer and importer. The global production of pulses is about 70 million tonnes, of which India’s share is around 25 percent.

The consumption of pulses is historically part and parcel of Indian culture. However, over a period of time, the availability of pulses has declined from69 gram per capita per day in 1961 to 51 gram in 1971 and 38grams in 1981. Marginally it arose to 42 gram in 1991 which already declined to 30 gram in 2001. The National Food Security Mission (NFSM) was started by the union Government for pulses during 2007. It did not result in a significant increase in the output because pulses are grown only in 16 per cent area which is irrigated. The area under cultivation for pulses varied from 23 million hectare in 2009- 2010 and 26 million hectares 2021-2022 and production was14.6 mt. to 28.9 mt. At present the availability of pulses is about 42 g per capita per day.

Rose (Rosa centifolia Linn) belongs to the family Rosaceae is known as flower of love which is cultivated throughout the world. The traditionally grown rose f lowers are fragile wild, bloom only for a limited period. They are found in a few colours of red, pink, deep crimson vis-a-vis white colour. However, with the development of the clonal technology, tissue culture and hybridization, a wide variety of roses can be grown having different colours, fragrances, blooms and shapes. It is point to mention that from the 200 species of roses originally found there are more than 30,000 varieties available these days.

The cultivation of rose is believed to have started about 5.000 years ago in China. Initially, Romans started to cultivate the rose flower using organic manures for medicinal purposes and then tor aesthetic values. Briefly their medicinal values have been mentioned separately as reported by Gupta et al 2016. It is not until late 8th century that cultivation of roses was introduced into Europe. Unlike Europe and America where rosses have limited flowering period during the summer.
