12.1 Introduction

French bean (Phaseolus vulgaris L.) is one of the most important legume vegetables grown for its tender green pods for fresh consumption, processing and dry seeds. The pods are slender, 10-25 cm long, straight or slightly curved with prominent beak. Seeds are kidney shaped, elongated and white, red, purple or blackish in colour or mottled. The vegetable is in great demand in cities and is grown both commercially and in home gardens. Its major area is confined to hills, where it is grown for green pods. Punjab, Jammu and Kashmir, Gujarat, Karnataka, Tamil Nadu, Uttar Pradesh and Himachal Pradesh are the main states where it is being cultivated on large scale. Dry bean seeds are an excellent source of cheap protein and many cultivars contain 22-23 % protein. Hundred grams of edible fresh pods contain 91.4 % water, 1.7 % protein, 0.1 % fat, 0.5 % mineral matters, 4.5 % carbohydrates, 50 mg Ca, 28 mg P and 1.7 mg Fe. Its 100 g dry seeds contain 9.6 % water, 24.9 % protein, 0.8 % fat, 3.2 % mineral matters, 60.1 % carbohydrates, 60 mg Ca, 433 mg P and 2.4 mg Fe. In India, it is mostly grown for fresh consumption, while in USA it is grown for processing in large quantities. Dried beans are rich in protein and closely compared with meat. Phaseolus oborigineus is the progenitor of French bean. They are capable of utilizing atmospheric nitrogen with the aid of bacteria found in the nodules on the roots of the plants. Four cultivated species are seen under the genus Phaseolus, i.e., Phaseolus vulgaris—common red kidney bean, Phaseolus coccineus—scarlet runner bean, Phaseolus lanatus— Lima bean, Phaseolus acutifolius var. latifolius— Moth bean or Tapery bean. All the species are self-pollinated except lima bean which is often cross-pollinated and Phaseolus coccineus is generally cross-pollinated and long day plant.

1. Introduction

There is intense commercial interest in dehydrated fruit and vegetable products especially mango powder, banana powder, orange powder, papaya cereal flakes to powder, tomato juice powder and other vegetable powders, which are in great demand for soups, biscuit type cookies supplemented with fruit powders (Ana Maria et al. 2009; Sunita and Chauhan 2008), pizza mixes and sauces. Natural fruit and vegetable powders are gaining lot of popularity in recent years as they are very easy to handle after production, require minimum storage space and they are attractive. Tamarind powder is developed from tamarind fruit (Tamarindus indica) (Manjunath et al. 1991) and recently cashew apple and guava residues from fruit juice industry were successfully converted into fruit powders and used at different levels of wheat flour substitution for cookies formulation (Ana Maria et al.2009) and fruit puree like papaya can be mixed with cereal flour to prepare slurry and after gelatinization, the slurry can be useful for preparing drum dried flakes and powder (Sunita and Chauhan 2008). Tropical fruits are exotic in flavor but their juices and purees are seldom available in dehydrated powder (James, 1971). Citrus juice concentrates were produced during world war II in powdered form by using spray, drum, vacuum-puff, and freeze drying (USDA, 1962). The preservation of fruits and vegetables by dehydration offers a unique method, which may be considered as an alternative low cost preservation technique. A shift from fresh to more and more processed foods with significant value addition is bound to occur sooner or later considering the socio-economic changes taking place in the country and the rapid integration of Indian economy with global system. Most popular brands are found in the “ready to consume” food sector.

    14.1 Dry land ecosystem of Jammu and Kashmir
Geographically, Jammu and Kashmir state is divided into various zones- the mountainous plain known as Kandi belt, hills including Shiwaliks ranges, mountains of Kashmir valley and Pir Panjal range, and Tibetan tract of ladakh and kargil. The maximum areas of Jammu division is existing in rainfed condition and are known as kandi belt or sub-mountane region which includes the lower shiwalik region. The soils of kandi belt are light to dark colored, well drained, severely eroded and with varying degree of stoniness. These soils are neutral to slightly alkaline nature, low organic matter and poor in fertility. In these areas, mango, guava, aonla, phalsa, citrus, bael, ber and jamun are commonly grown as all these fruit crops are survived under rainfed condition or require less irrigations. In these areas the normal rainfall is nearly 900-1000 mm with a high co-efficient of dissimilarity. The rainfall division patterns are especially erratic in time and space which leads to moisture stress situation. About 70 to 80 per cent the annual rainfall occurs during from July to September as a result of the South-West monsoon. April to June and October to November are the driest months and is scarcity of water. Therefore the farmers are suffering by growing the agricultural crops and they have tremendous scope for growing fruit crops. These crops are less water requiring as compared to agricultural crops. Therefore RRSS, Raya, SKUAST-Jammu was initiated since 2016 for systematic research work for collection of germplasm, conservation, evaluation and utilization of red flush guava strains for growers community (Anonymous, 2022).

11.1 INTRODUCTION

The term ‘Dolichos’ derived from Greek language means long pod and ‘lablab’, an Arabic term, means production of sound by dried seeds in the pods. In India, it is grown all over the country but compact large acreage for commercial production is uncommon. It is grown for whole pod. Fresh seeds and dry seeds are used as pulse grain. It is used as pod vegetable, feed and green manure crop. It is very popular in villages as well as cities where less area is available for cultivation. The young tender leaves are used in salads and the relatively old leaves are cooked as potherb like spinach. Its fresh green pods contain 86% moisture, 3.8% protein, 6.7% carbohydrate, 0.7% fat, 0.9% mineral matter, Vitamin A 312 IU. It is good source of Vitamin B, Vitamin C, proteins, minerals and dietary fibres. Trypsin inhibitor and several anti-nutritional factors such as tannins and phytates are present in mature and dark coloured seeds. On heating it is broken down into toxic cyanogenic glucoside which is soluble in boiling water. Therefore, it is necessary to boil the mature seeds in water before consumption. Sem is of two types.(A) Dolichos purpureus var. typicus (Graden Type) is with soft, edible pod wall having less fibre. (B) Dolichos purpureus var. lignosus(Field bean) that is grown for fresh dry seed as pulse, pod wall has high fibre content and has characteristic aroma. Hyacinth bean is a perennial herbaceous plant often grown as an annual and pole types are photosensitive.

India is a natural reservoir of the several fruit species. The several less known fruit species, which have the potential for commercial exploitation, are yet to be utilized to their potential. An attention to the less known fruit would play a significant role in increasing the income, providing employment opportunities, uplifting of the poor, small and marginal farmers and the development of value added products. These fruits are well known for their medicinal and nutritive value. There is a great need to develop and popularize not only for their domestic market but also for their export. Some of the less known fruits are described here with respect to their cultivation technology.

Importance

Ajwain is an important seed spice and is also useful for its medicinal values. It is a traditional potential herb for curing many ailments in human and animals. It is usually used as a digestive aid, relieves abdominal discomfort due to indigestion and antiseptic. The seeds of ajwain is bitter, pungent and contain 2-4.4% brown coloured oil known as ajwain oil. The main component of this oil is Thymol, which is used as gastrointestinal ailment, lack of appetite and bronchial problems. Thymol is also used in toothpaste and perfumery (Joshi, 2000). Seeds are also used for curing abdominal pains, abdominal tumors and piles (Krishnamoorty and Madalgeri, 1999). In southern parts of India dry ajwain seeds are powdered and soaked in milk, which is then filtered and fed to babies as it relieves colic in babies. It can be used as digestive mixture in large animals.

14.1 INTRODUCTION

Drumstick is one of the most popular perennial tree vegetables in the south Indian households and known as miracle tree. This perennial vegetable survives for several years and goes on yielding vegetables without much care and attention, and is planted on the side of the kitchen garden without much interference with tillage operations of other annual crops. The fruits, leaves and flowers are used in culinary preparation. Immature fruits are cut into pieces and used in several culinary dishes. Fruits are rich in Vitamin C, carotene, Phosphorus and minerals like Mg, K, S, Cl etc. Tender leaves and flowers are comparable to that of Colocasia in vitamins and minerals. Drumstick leaves contain high amount of vitamin A (four times more than carrot), vitamin C (seven times more than orange), protein (5-10%), calcium (four times more than milk) and potassium (three times more than banana).The roots of the plant are used for seasoning pickles. Its roots are a good substitute for Horse Radish so called as Horse radish tree. It is highly valued for the distinct and appealing flavour for its tender fruits. They are rich source of protein, minerals and vitamins. Seeds contain an oil called ben or behen oil which has been much used for illumination, soap industry and highly priced for lubricating watches, computers, delicate machinery and so known as Ben oil tree. Seeds contain 38-40% of non-drying oil which is clear and odourless, that never becoming rancid. The oil contains high levels of unsaturated fatty acids, especially oleic acid up to 67.8%. It is edible and useful in the manufacture of perfumes and hair dressing. The press cake remaining after oil extraction is high in saponin, not edible, but utilized as manure. The oil cake is a water coagulant and used for purifying effluent water. It is used as organic substitute for water purifying chemicals such as aluminium sulphate. Wood yields blue dye and coarse fibre. The plant is used for treatment of rheumatism and as cardiac and circulating system stimulants. It has fragile and cory stem. The trunk is gaining importance as a raw material for paper making. The gum of stem has medicinal properties. The leaves are usually tri-pinnate with elliptic leaflets. Seeds are trigonous with wings on angles. Flowers are produced on current seasons growth on large and erect panicles or monocladial cymes. Flowers are yellowish creamy white and sweet smelling. It is a cross-pollinated crop. Pollinator is carpenter bees, bumble bee, honey bee and flee beetle. Flowering mostly varies from place to place and is greatly influenced by rain, temperature, humidity, wind, soil moisture and soil temperature etc. Peak period of flowering in central parts of India and Kerala is December-January while in southern part it is February-March and July-August with maximum flowering in February-March. Fruits take 60 days for horticultural maturity during rainy season while 30 days in summer.

Botanical Name: Elaeis guineensis Jacq.

Family: Arecaceae / Palmae

Chromosome No: 32

Place of Origin: Guinea Coast of West Africa

Common Name: Oil Palm

4.1 Introduction

The cultivated oil palm Elaeis guineensis Jacq. is a native of West Africa and exists in wild, semi- wild and cultivated forms. It was introduced as an ornamental crop in 1860 and planted at National Botanical Garden, Kolkata. Research on oil palm in India started during 1960 with the establishment of a research station at Thodupuzha by the Department of Agriculture, Kerala with Dura and Tenera germplasm imported from Malaysia and Nigeria. National Research Centre (NRC) for oil palm is situated at Elur, Andhra Pradesh. Oil palm crop is one of the highest oil yielding crops among all perennial crops. It gives 4 to 6 tonnes of edible oil/ha from 3 to 25 years of its life span compared to less than one tonne of oil per ha from other cultivated oil yielding crops. This oil palm is considered as golden palm due to its high yielding capacity. Among the 10 major oilseeds, oil palm is accounted for 5.5% of global land use for cultivation, but produced 32.0% of global oils and fats output.

7.1 INTRODUCTION

Okra is a remunerative vegetable crop for the tropical and subtropical regions of the world. Its fresh fruits are important vegetable in India, Brazil, West Africa and many other countries. For year-round consumption sun dried (Africa, India), and frozen and sterilized (USA) fruits are processed from fresh fruits. Tender green fruits are cooked in curry and also used in soups. The root and stem are useful for clearing cane juice in preparation of jaggery. Its ripe seeds are roasted, ground and used as a substitute for coffee in Turkey. Matured fruits and stems containing crude fibre are used in the paper industry. Okra is rich in vitamins, calcium, potassium and other minerals. A 100g consumable unripe okra fruits contain 10.4g dry matter, 3,100 calorie energy, 1.8g protein, 90mg calcium, 1.0mg iron, 0.1mg carotene, 0.07mg thiamin, 0.08mg riboflavin, 0.08mg niacin and 18 mg vitamin C. The dry seeds contain 13-22% edible oil and 20-24% protein. The seed cake is also used as an animal feed. Okra has high iodine content and it has ability to control goiter. Ratoon cropping can also be done in okra.

Botanical Name: Borassus flabellifer L.

Family: Arecaceae

Chromosome No: 36

Place of Origin: Tropical region of Africa, Asia and New Guinea

5.1 Introduction

Palmyrah is a monocotyledon and perennial crop. The word “Borassus” was derived from a Greek word and it means the leathery covering of the fruit and “flabellifer”, means fan-bearer. The distinguishing characters of palm in this genus are their palmate, fanlike leaves and dioecious character, i.e., male and female flowers are borne on separate trees (sex ratio 1:1), allotetraploid (X= 8 or 9, n = 18), the male tree has a heteromorphic XY pair of chromosomes while the female has an XX pair (Sankaralingam et al., 1999). Next to coconut, palmyrah is the most abundant palm found in the world. Palmyrah thrives in arid conditions and is grown extensively in Tamil Nadu. Palakkad district of Kerala is popularly known as land of palmyra trees. Palmyra trees are known as the icon of this district and have a vast cultural, heritage and literary association.

Importance

It is one of the most valuable primary products in world trade, in many years second in value only to oil as a source of foreign exchange to producing countries. Its cultivation, processing, trading, transportation and marketing provide employment for hundreds of millions of people worldwide. Coffee is crucial to the economies and politics of many developing countries; for many of the world’s Least Developed Countries, exports of coffee account for more than 50 percent of their foreign exchange earnings. Coffee is a traded commodity on major futures and commodity exchanges, most importantly in London and New York.

16.1 INTRODUCTION

Portulaca is an annual potherb, but may be perennial in the tropics. In many parts of the world, it is still regarded as a weed with nutritional potential. Its young stems and leaves are succulent and edible with a slightly acidic and salty taste. Stems are glabrous, f leshy, purplish-red to green, arising from a taproot, often prostrate, forming mats. It is described as a power food of the future because of its high nutritive and antioxidant properties. It contains more omega-3 fatty acids (300 to 400 mg/100 g of fresh leaves) than any other leafy vegetable plant. Succulent leaves and stem also contain dietary minerals, such as calcium, phosphorus, iron and potassium, as well as vitamins A, C and E and some amount of vitamin B and carotenoids. It has been recommended as a cholesterol lowering agent and as a therapy for arteriosclerosis. Generally, roots and leaves contain more iron and manganese than stems. Due to oxalic acid and nitrate content, excessive consumption of purslane is not recommended. The cultivated form of Purslane, i.e., Portulaca oleracea (garden or green purslane) and Portulaca sativa (yellow leaves, less hardy than the green purslane but possessing the same qualities), is hexaploid. Purslane is a succulent and well-branched herb, leaves are spirally arranged, f lowers are yellow, stamens 7-10, style with arms, fruit ovoid, capsule, seeds numerous, tiny and black in colour.
