17.1 INTRODUCTION

Flower consumption is growing at an alarming rate of 20 per cent per annum at global level and India is, today, one of the world’s largest consumer base and fastest growing retail destinations. Commercial floriculture is today a potential money-spinner and an economically viable agri-business.

Cut flower trade in terms of export oriented units dealing with rose and gerbera is flourishing. Other cut flowers like gladiolus, tuberose, lilum, chrysanthemum, etc. are also being cultivated along with traditional loose flowers like jasmine, rose, crossendra, marigold on a higher scale. However, growing awareness of Indian consumers and popularity for cut flowers is creating demand for diversified flower crops. Further, trade of some flowers in the market is responsible for gluts. Thus, there is an urgent need to diversify the floriculture industry by introducing and adoption of anthurium as a cut flower with unique shape and high longevity.

Precision farming is an advanced approach for the flower growers to enhance their income. It mainly includes information and technology of farm management system to identify, analyze and manage variability within fields for optimum profitability, sustainability and protection of the land resource. Precision farming is applied for increasing efficiencies that can be realized by understanding and dealing with the natural variability found within a field.

Anthurium is taking a good place in market with high value. Farmers are undertaking anthurium cultivation and in this direction, precise farming technology will help the farmers to grow the crop with good quality and higher production per unit area.

1. Introduction

Cumin (Cuminum cyminum L.) crop belongs to the family Apiaceae and having diploid chromosome number 2n =14. It is also known as Jeera in Hindi. This crop is originated from Mediterranean region. It is an erect or sub erect, glabrous annual herb which grows to a height of 30-50cm. The leaves are alternate, compound and green, the blade consists of three slender filiform leaflets. The inflorescence is a compound umbel with white or pinkish flowers (Verma et al., 2018a). The typical pleasant aroma of the seeds is due to their essential oil and the main constituent in essential oil is cuminaldehyde. It is mainly cultivated in arid and semi arid parts of Gujarat and Rajasthan. The total area is about 12 lakh hectare with the production of about 8.5 lakh tons and total export of cumin is worth of more than Rs. 4200 crore during 2020-21 (Fig. 1 & 2). 

1. Introduction

There are around six hundred major and minor crop species but only two percent are cultivated commercially meeting the food (calorie) requirements. The most commonly cultivated food plants are even smaller counting to merely 20 crops (Wilkes, 1984). The huge number of underutilized crops may serve as potential fruit crops to meet the nutritional requirements of poor farming households in lesser common farming and subsistence agriculture. The adoption of underutilized crops on a commercial scale may not be possible without crop improvement, standardized agronomic and fertilizer management technologies, pre- and post-harvesting techniques and marketing (Bag Mal et al., 1997).

1. INTRODUCTION

Medicinal plants constitute considerably a large component of natural vegetation. Several of these species are in great demand for domestic consumption as well as for commercial use by the herbal industry. About 800 species are estimated to be in trade with a turnover of Rs.4000 crores per year. This high demand by the herbal industry has put enormous pressure on the wild populations leading to destructive collection of the produce as maximum species of medicinal plants are wild.

A medicinal plant is as any plant which contains substances that can be used for therapeutic purposes or which are precursor for chemo- pharmaceutical synthesis. The medicinal plants are useful as a drug or therapeutic agent, having different medicinal values in form of active ingredient. Medicinal plants may therefore be defined as a group of plants that possess some special properties or virtues which make them important as drugs, therapeutic agents and for medicinal purposes.

Medicines from India are used by about 60 per cent of the world’s population. These are not only used for primary health care not just in rural areas in developing countries, but also in developed countries as well where modern medicines are predominantly used. While the traditional medicines are derived from medicinal plants, the herbal drugs are prepared from medicinal plants only. Use of plants as a source of medicine has been an ancient practice and is an important component of the health care system in India. There are about 45,000 medicinal plant species in India, with concentrated spots in the region of Eastern Himalayas, Western Himalayas, Western Ghats and Andaman & Nicobar Island. India is the largest producer of medicinal herbs and is called the botanical garden of the world. In rural India, 70 per cent of the population depends on the traditional type of medicine, the Ayurveda. Ayurveda and Kabiraji (herbal medicine) are two important forms of alternative medicine that is widely available in India. It is estimated that about 80,000 species of plants are utilized in some form or other by the different systems of Indian medicine. Many herbs and spices are used in Indian cooking, such as onion, garlic, ginger, turmeric, clove, cardamom, cinnamom, cumin, coriander, fenugreek, fennel, ajowan (ajwain), anise, amchur, bay leaf, hing (asafoetida) etc. Ayurvedic medicine uses all of these either in diet or as a medicine.

Curing- Curing is a process in which produce is subjected to undergow through a special treatment to get the quality product.

Abstract

Himachal Pradesh has achieved a transformation in the horticulture sector during the last fifty years. The total area under fruits, which was only 793 hectares in 1950 has increased to 1.82 lakh Hectares during 2003-04, out of which temperate fruits alone cover an area of 1.20 lakh hectares. Fruit production has also increased from 1200 M.T. in 1950 to 6.92 lakh MT during 2004-05, with temperate fruits accounting for 5.92 lakh MT.  Around 4.64 lakh farmers are estimated to be involved in the fruit production programme and the fruit industry generates a gross domestic income of about Rs. 1000 crores annually. The existing problems and constraints have been identified and the remedial measures required to provide the desired impetus to the horticulture industry of the State, elaborated.

Abstract

India has now become the largest producer of fruits after China by producing 45.2 million tones of fruits from 3.78 million hectare area (NHB, 2004). India is first in the production of mango, banana, sapota and acid lime. India has also recorded highest productivity in grapes, sapota and acid lime in the world. India produces about 40 fruits commercially; however, the major share is from tropical and subtropical fruits like mango (28.17%), banana (29.43%), citrus (15.56 %), guava (3.97%) and grapes (2.76 %). Among temperate fruits apple has maximum area and production and 2. 98 % share in total production. Temperate fruits growing in India spread over some 18 states. These states are categorized into 3 major regions, namely, Northern Western Himalayan Region (NWHR), North Eastern Himalayan Region (NEHR) and other hilly areas.

Introduction

Vegetables are the vital sources of minerals, vitamins and dietary fibres and play an important role in supplying nutrition to human health. Vegetables require comparatively lesser quantities of agro-inputs to grow. Vegetables are rich source of vitamins, minerals and plant fibres which provide food and nutritional security. These also generate high income and employment, particularly for small farmers. Vegetables being a rich and cheap source of vitamins and minerals, occupy an important place in the food basket of Indian consumers, a majority of whom are vegetarian. This persistent vegetarianism coupled with rising per capita income is fuelling a rapid growth in consumption of vegetables. Presently, India is producing more then 70 types of vegetables which are capable of meet out the economic and nutritional requirement of the country (Table 1). There has been a revolution in the production of vegetables in the country in the last four decades.

Current Trends in Fruit Exports from India

Fruit culture in the Indian subcontinent dates back to the Harappan civilization when datepalm, pomegranate and lemon were domesticated. Fruits such as aonla, bael, jackfruit, karonda, phalsa, mango, pomegranate, almond, walnut and pistachio are mentioned in Charaka Samhita (300 BC) and Sushruta Samhita (400 BC), the oldest known texts on ayurveda. Owing to diverse agro climatic conditions, India can produce a wide range of tropical, subtropical, arid and temperate fruits. In the past few decades, India had made rapid strides in fruit production and is currently the second largest producer of fruits in the world, next only to China. The annual production is estimated to be about 81 million tonnes for about 12.6% of the total world production. However, India’s share in the global export of fresh fruits is less than 5 per cent. The major fruits exported in terms of quantity are grape, mango, banana and pomegranate. In value terms, grapes and mango earn the maximum foreign exchange for India.

Curry leaf (Murraya koenigii Spreng. Syn. Bergera koenigii Koen (N.O Aurantiaceae), Chaleas koenigii Curz ex. Swingle) is a perennial leaf vegetable. It belongs to family Rutaceae. Its genus name ‘Murraya’commemorates John Adam Murray, Professor of Botany at Gottingen and editor of many of Linnaeus’s works. (Fyson, 1977).

Origin and Distribution

The crop originated in the tarai tract of Uttar Pradesh (India), in the foothills of the Himalayas. Wild forms with less pungent leaves are seen along the plains and hills of Himalayas extending from Kumaon to Sikkim, in Bengal, Assam, Deccan plateau and in Western Ghats. At present, it is cultivated in Myanmar, SriLanka, China, Australia and Pacific Islands. The curry leaf grows throughout India including the Andaman Islands up to an altitude of 1500 m amol (Wealth of India, 1962). Dastur (1970) recorded its wild form in Garhwal hills in Uttaranchal, Sikkim, Bengal, Assam, Central India, Western Ghats, Tamil Nadu and Kerala.  Used as a flavourant and as a leaf vegetable by the early inhabitants, Dravidians, curry leaf was introduced to Southern India when the Dravidians moved southward after the arrival of Aryans from Persia. It is a backyard crop in many of the South Indian homesteads.  The spicy leaves of plants are used extensively for seasoning and flavouring dishes.

Custard apple (Annona squamosa L.), also known as sitaphal, sharifa, sugar apple  is a  nutritious, edible fruit of  family Annonaceae. It is a drought hardy, deciduous fruit tree and most suitable for dry land horticulture. Annonaceous fruits originated in tropical America and are widely distributed in tropics and sub tropics. Among Annona fruits, custard apple is the most favourite in our country. Its plants come up unattended in parts of Andhra Pradesh, Assam, Bihar, Karnataka, Maharashtra, Madhya Pradesh, Odisha, Rajasthan and Tamil Nadu. Due to hardy nature and escape from animal’s damage, this plant species is grown in different tropical and sub-tropical regions of the country. Of late, custard apple has gained commercial significance and exclusive orchards are emerging in Maharashtra, Andhra Pradesh, Gujarat and Rajasthan. A wide range of genetic diversity is available in Anonaceous fruits in many parts of country. It is naturally grown in Aravali belt especially in Udaipur, Sirohi district of Rajasthan and its potential should be exploited for improvement (Chundawat, 1990). The plant of this species is shrub or small size tree and very important in both horticulture and in ethno-botanical use. However, the maximum area of its cultivation is in Maharashtra and Karnataka  state. The area are being expanded because of its  prospects in semi arid and  dry parts of the country.

Mealy bugs: Ferrisia virgata, Planococcous lilacinus, P. pacificus, Maconellicoccus hirsutus, Perisopneumon ferox: Pseudococcidae

The fruit is seen covered with a mealy coating due to colonies of small reddish-white mealy bugs. They also infest leaves, shoots and buds. Due to sucking of sap by nymphs and adult female mealy bugs, fruits remain small in size and become shrivelled. Large number of mealy bugs is seen in the tip of the petiole abd also on the grooves of fruits epicarp. The fruit also becomes blackish due to the development of sooty mould.

34.1. Aim

To conduct cut out analysis of canned fruits and vegetable products.

34.2. Theory

Cut out examination of canned products is conducted to evaluate the product whether confirming to FSSAI standards or not. Canned fruit and vegetables are evaluated for presence of vacuum or pressure in the can, drained weight, total soluble solids, presence or absence of preservative, internal condition of can product contents and presence or absence of fermentation for ensuring microbiological safety.

A cut-out examination is conducted for the evaluation of canned fruit and vegetables and other products for various quality attributes, viz., physical, chemical, sensory, and microbiological attributes. The examination is conducted by following the undermentioned steps: External/physical examination of unopened Can
1. External Appearance of the tin can: Note the external condition of the tin can like dents, rusty spots, scratches, leakage around seams, and the condition of ends. Based on external appearance describe the condition of the tin can by using the following terms:
i. Flat Can: A can where both ends are concave. The vacuum is high enough to maintain the ends concave.
ii. Flipper Can: A can where the vacuum is so low that mechanical shock will produce distortion of one or both ends.
iii. Springer Can: A can in which one end is distorted and the other end is flat and pressure on the convex end will cause the flat end to spring out when pressed.

Date palm (Phoenix dactylifera L.) known as Khajoor, Kharek is an important fruit tree of semi-arid and arid regions of the world. It grows well under poor desertic soils due to its hardy plant characteristics and deep root system.  It is also one of the most suitable fruit plant, which can be easily grown under saline irrigation conditions. It is well known fact for date palm that its feet in the water and its head in sun. It requires dry hot climate for growth and development of fruits. In arid region, crop production is risky preposition, where date palm cultivation contributes in achieving food security, high nutritive value food, crop diversification, desertification control, income generation and foreign exchange earnings. It can be grown at such areas where adequate irrigation facilities are available besides other climatic requirements (Chandra et al., 1992; Sharma and Singh, 2013).

Introduction

Date palm (Phoenix dactylifera L.) is a monocotyledonous and dieocious species belonging to the family Palmae. The Latin name of the date palm, Phoenix dactylifera, is derived from the Phoenician name “Phoenix,” which means date palm, and dactylifera is derived from the Greek word “daktulos,” which means a finger. In India, generally, two species of Phoenix are found, of which, Phoenix sylvestris Roxb. called “desi khajoor,” is found throughout the country but t produces inferior quality fruits. The fruit contains large stones with less pulp content.

Date palm is considered one of the world’s oldest cultivated fruit trees. Archeological evidence suggests that the date palm was domesticated some 6000 years ago in the Mesopotamian region. It is widely cultivated in arid regions of the Middle East and North Africa. It is also one of the most appropriate fruit trees, and it can be easily grown under saline soil and water conditions. It grows well in poor, arid soils due to its hardy plant characteristics and deep root system. Date palm is believed to be indigenous to countries around the Persian Gulf. In the Indus Valley, date palm is believed to have been introduced by the soldiers of Alexander the Great in the fourth century B.C. and during the Muslim invasions at the beginning of the eight century AD. Date palm was commercially cultivated in Iraq, Saudi Arabia, Algeria, Iran, Egypt, Morocco, Tunisia, Pakistan, and Sudan, among many other Near East and North African countries. In India, dates are grown in the states of Gujarat, Rajasthan, Punjab, Haryana, and Tamil Nadu (Table 1).

Semilooper: Thysanoplusia(Plusia) orichalcea : Noctuidae

Bluish green or grey coloured eggs are laid singly on lower surface of leaves.The larvae are semi loopers and feed voraciously on leaves and cause defoliation of the plants.

Storage of paddy seed lots after harvesting is one of the crucial aspects of processing shopfloor. Paddy due to increased mechanised harvesting may loose vital seed quality parameters. Since seed growers cannot buy a combined harvester themselves-they resort to hiring of this machine. Sometimes in the hurry of completing harvesting they harvest the crop at un-safe moisture content. This un-safe moisture content may go up to 50-60% also. Harvesting of seed crop with high moisture has adverse effect on storability. Ensuring safe seed moisture is very critical especially during rabi-summer seed production cycle. Most of the growers depend on sun drying for reducing the seed moisture. But paddy should not be dried >3% in one cycle. Follow tempering and convection cooling after every cycle and repeat the cycle till seed attains safe moisture content (14%).

1. INTRODUCTION

Plant diseases are major constraints to plant growth and development (from seed to maturity) resulting in crop losses. Plants are exposed to attack, by a wide variety of microbes like bacteria, virus, fungi, phytoplasma and as an abnormality they cause disease. To counter these threats, plants have evolved a series of defense systems in response to the pathogen challenge inhibiting natural resistance. Thus disease is an exception rather than rule. However on failure of the inbuilt resistance mechanism, outbreak of disease has led to the widespread use of chemicals that have deleterious environmental and human health consequences. To enable the development of more effective and durable resistance against pathogens, a detailed analysis is necessary to identify the genes and mechanisms involved in plant defense/resistance.

Recombinant DNA and gene transformation technologies have potential to augment traditional breeding efforts (limited by genetic variability) by circumventing taxonomic limitations to gene pool for pathogen resistance. Further manipulation of defense genes in transgenic plants provide novel approaches for engineering pathogen resistance. It becomes important to understand the different components of plant defense to exploit host plants for resistance Thus the review is focused on plant genes and proteins that are known to play a major role in plant resistant against pathogens.

Drying and dehydration are interrelated terms. Drying generally refers to the method of removal of moisture from the food under natural conditions such as sunlight and wind for example open sun drying, shade drying etc. Whereas, dehydration refers to a process of removal of moisture by application of artificial heat under controlled conditions of temperature and airflow. In this case single layer of fruit and vegetables, either whole or sliced after primary pretreatments is spread on trays which are placed inside the dehydrator or in the open sun for drying. In the dehydrator, the initial temperature is generally kept at 43oC which is then gradually increased to 66-71oC for fruits and 60- 66oC for vegetables. Dried grapes (raisins and monucca), apricots, dates, apple rings/cubes, Morchella (Guchhi), bael, aonla, fig, green peas, cauliflower, cabbage, onion, garlic etc are commercial products prepared by using drying.
Procedure for drying: Drying generally involves three stages: pre-drying treatments or pre-treatments, drying of commodity and post-drying operations such as handling, packaging and storage. The flow sheet for drying of fruit and vegetables is shown in Figure 1 and details of pretreatments for drying fruits and vegetables are shown in Table 1&2 respectively.
