Intercropping with food crops and vegetables is widely practiced by small and marginal farmers of the world mainly belonging to arid and semi-arid regions. Because of several benefits obtained, farmers prefer to adopt intercropping system. In temperate regions, mixed stands of cover crops and combinations of cereal and legumes forage production are very common.

Abstract

A field experiment was  carried out in the young orchard of Apricot cv. New Castle using Okra. cv. P-7 as an intercrop  to study the economics of growing intercrop in the newly planted orchards which has practically no output for the first three years. It was concluded that one can not only save the input expenditure of Rs.66,258 (for the maintenance of orchard plants during the first three years), an additional income of Rs. 2,41,858, with a net return of Rs. 1,23,800 can also be generated. There was neither any adverse effect of apricot plant canopy on the yield and performance of okra, nor was there any effect of cultivating okra on the growth and performance of apricot plants.

Abstract

Studies were conducted to investigate the effect of growing media and fertilizers on growth and flowering of rose cultivar ‘First Red’ under naturally ventilated polyhouse. During first flush, it was observed that growing medium containing soil, FYM, sawdust (2:1:1) gave maximum flower yield (5.58 cut stems) per square meter per month when fertilized with water soluble fertilizers (N-150 ppm and K-200 ppm) whereas, maximum number of ‘A’ and ‘C’ grade cut stems were recorded from plants grown in soil: FYM: sand which were fed with straight fertilizers (N-150 ppm and K-200 ppm).

Abstract

Soils of various depth ranges were identified at the experimental farm of Central Arid Zone Research Institute, Regional Research Station, Kukma-Bhuj, Gujarat. Different depth range of soils included in this study were shallow soil (effective soil depth <15 cm), moderately deep soil (effective soil depth15- 25 cm), deep (effective soil depth 25-70 cm), and very deep (effective soil depth 70 to >1m). The soils are developed from calcareous and ferruginous sand stone and mud stone. A field experiment was carried out to study the performance of different crops and grasses under variable soil depths. Crops namely, clusterbean (Maruguar), greengram (K 851), sesame (GT2), groundnut (GG2) and pearl millet (Pusa 23) and grasses C .ciliaris (CAZRI-75) and L. sindicus (CAZRI 30-5) were grown in these four different soil depths.

Abstract

The runners of ten strawberry cultivars were procured from different research stations, planted in the last week of October every year and mulched with paddy straw.  The earliest flowering was observed in Chandler, which produced the largest sized fruits (13.20 g) followedby Dana.(3.6 g). Higher incidence of fruit rot was observed in Chandler (26.2%) and least in the Sweet Charlie (9.3%). Sweet Charlie produced medium sized (11.80 g), highly glossy and attractive fruits having high TSS (10.2%), and minimum fruit rot can be better substitute for Chandler in sub-tropical areas.

Abstract

In India, women’s economic productivity is rather critical to 60 million households whose family members live below the poverty line. Therefore, the empowerment of poor women is vital for bringing down rural poverty.  The operation of the DWCRA project during the VIII plan of government of India (GOI) had inadequate impact and therefore, failed in organizing cohesion within and among the groups to identify the activities that could generate sustained income.  Considering the importance of women and lacunae in the Rural development programmes, Swarnajayanti Grama Swarozgar Yojana (SGSY) was evolved and was launched on 1st April, 1999. With this, the erstwhile programmes viz. IRDP, DWCRA, TRYSEM, SITRA, GKY and MWs ceased operation.  SGSY aims at establishing a large number of micro enterprises in the rural areas. The ‘beneficiary’ families (known as Swarozgaris) may be individuals or groups (Self Help Groups).

2.1 Introduction

Perfumery, the art of making perfumes, began in ancient Egypt but was developed and further refined by the Romans and the Arabs. The history of perfume began in antiquity. The word perfume is used today to describe scented mixtures and is derived from the Latin word, “per fumum”, meaning through smoke. Although perfume and perfumery also existed in East Asia, much of its fragrances are incense based. The world’s first recorded perfume maker Tapputi was mentioned in a Cuneiform tablet from the 2nd millennium BC in Mesopotamia. Perfume and perfumery also existed in India. The earliest distillation of Attar was mentioned in the Hindu Ayurvedic Charaka Samhita. The Bible describes a sacred perfume, consisting of liquid myrrh, fragrant cinnamon and cassia. In Islamic culture, perfume usage has been documented as far back as the 6^th century and its usage is considered a religious duty. Al-Kindi in the 9^th century wrote a book on perfumes entitled ‘Book of the Chemistry of Perfume and Distillations’ that has more than hundred recipes for fragrant oils, salves, aromatic waters and substitutes or imitations of costly drugs.

French author Jean Giono once remarked, “The God creates the Odours, but the men manufacture the perfumes”. In today’s world, fragrances play bigger role than just being associated with a tiny bottle of liquid. It now serves the larger purpose of linking itself with anything you can imagine, from soaps to your favourite sweater knitted by your grandmother (Biswas, 2012). In the modern day, these products find their applications in items for personal sophistication to culinary delights and beverages, to a host of industrial products (Dev, 1993). India, a country known for its vast range of fragrant flowers and herbs, has used extracts from such raw material to produce incense sticks, medicines, body massage oils and sweet savouries.

The word ‘perfume’ is derived from the Latin term ‘perfumen’, meaning ‘through smoke’. Perfume is a fragrant liquid mainly distilled from natural oils, aromatic chemicals and resinoids; cologne is a lightly scented liquid used to cool the skin and deodorant contains chemicals to counter offensive body odour. Perfume is basically used by women, cologne by men and deodorant by both (Saha and Sareen, 1997). Throughout antiquity there was a continuous demand for incense, to mark the rites of scenting passage from birth to the grave, for the daily rituals of incensing rooms, linen and clothing. The South Asian synonym for perfume, ‘attar’, on the other hand, is derived from the Arabic word ‘aettr’ meaning ‘fat’ or ‘extract’. Almost all attars are basically aromatic oils extracted from flowers, plants and herbs through steam distillation. Some fragile flowers and oils that can not stand the heat of distillation are, however, crushed and the oil expelled by mechanical force (Mahmud, 1992).

Morphological characteristics

The plant is an erect undershrub, 1.5–2.5 m tall. Leaves are elliptic-oblong to lanceolate or ovate to ovate–lanceolate, 12–25 × 5–11 cm, acute or acuminate at apex, acute or cuneate at base, glabrescent, crenate-dentate; densely stellate–tomentose beneath; petiole 4–12 mm long; Fruits globose, drupes or berries, white to yellowish-brown with or without fruit stalk, fresh being succulent, 1–3 mm in dia. Intact fruits are smooth and brownish in colour and exhibit centrally located bilocular carpel and 4 nutlets each embedded with a yellowish white seed, in a transversely cut surface of a fruit;

Floral characteristics

Flowers appear in July-November are small, 0.5 cm long, pink in colour and crowded in axillary peduncled globose cymes, solitary, pedunculate or sessile. Flowers are bisexual, actinomorphic and fragrant. Calyx 4 or rarely 5 toothed, pubescent, corolla infundibular, 4 or rarely 5 lobed. Stamens are 4, exserted, anthers oblong 2 loculed, dorsifixed. Ovary is superior, 4 lobed, 4 loculed, 1 ovule in each locule, style short, stigma 2 lobed. Flowering & fruiting occurs during June–Dec. Fruits when tasted at first are somewhat sweet, later bitterish; fruit has fragrant odour specially after slight bruising the fruit. The fruits of Callicarpa macrophylla are edible.

Distribution

Plants of this species grow in open and secondary forests along the upper Gangetic plains, West Bengal Plains, Eastern and Western Himalayas, Kashmir, Assam, and northern Andhra Pradesh up to an altitude of 1800 meters. The species grows in other places worldwide, such as Nepal, Indonesia, China and South Korea.

Peri-parturient management is critical for reducing disease and mortality and ensuring healthy development of calves and replacement heifers. This chapter focuses on practical healthcare during the period surrounding birth and early life. Important areas include preparation for calving, neonatal care, colostrum management, hygiene, nutrition, disease prevention and monitoring of calf health. Proper colostrum feeding provides essential passive immunity and contributes to improved survival. Management practices during the calf and heifer stages influence future productivity and reproductive performance. The chapter emphasizes preventive care, early recognition of illness and appropriate management practices for producing healthy replacement animals.

Peri-parturient Health Care Periparturient period is defined as a period immediately around calving. It is the most critical time when high yielding cows are prone to nutritional deficits due to great metabolic alterations from dry to milking. Reduced feed intake and depressed immune system at this time make cows vulnerable to periparturient diseases affecting milk yield adversely and increasing mortality risk. Health care during this critical period aims at minimising deficits particularly in relation to dry matter intakes (DMI’s) and energy and mineral balance. •     Milk fever is the most common and important periparturient disease affecting high yielders. Due to the sudden onset of lactation, there is a huge demand for calcium resulting in dramatic decrease in blood calcium level during calving causing milk fever.

Introduction

Aquaculture has emerged as a viable business model having high growth potential for the entrepreneurs and start-ups in India. The rate of adoption of the aqua-business models for new age entrepreneurs has been very high in recent times. Some of the viable business models that are technology based and scalable have been attractive to the entrepreneurs are in the indoor aquaculture system like RAS, Biofloc systems. It offers many advantages like low space requirements, easy monitoring, higher level of intensification, easy management, short supply chain to the urban markets etc. These indoor aquaculture system are broadly defined as peri-urban aquaculture system offering high growth potential to the entreprenuers in India. The chapter provides a broad outline of the opportunities and recent trends of entrepreneurial developments through peri-urban aquaculture.

Entrepreneurship is the risk taking ability and readiness to venture into a new economic enterprise, along with all its challenges in order to make profit. One of the examples of entrepreneurship is the starting of new businesses in any field with business potential. In other words, entrepreneurship is the creation or extraction of economic value (Diochon et al. 2011; Gaddefors et al. 2017; Alvarez, et al. 2001). It is also viewed as a change, generally entailing risk beyond what is normally encountered in starting a business, which may include other values than simply economic ones. A person gets the benefits as he invests in one or more businesses, bearing most of the risks and availing most of the rewards. According to Shane (2000), entrepreneurship comprises both “enterprising individuals” and “entrepreneurial opportunities”[4]. An entrepreneur is generally seen as an innovator, a source of innovative ideas, services, and business.

Perianal gland tumors originate around the anus of the dog, upper and lower part of the tail and prepucial area. Retention of gonadal hormone receptors is one of the causes for perianal gland adenoma and adenocarcinoma.Cytology reveals the presence of hepatoid cells with centrally placed nuclei and prominent nucleoli. A small flattened reserve cells or resting cells are also noticed around the hepatoid cells. In malignant variety, the cells containing large vesicular nuclei, eosinophilic granular cytoplasm and binucleated cells, mitotic figures, reserve cells, moderate stroma and lymphoplasmacytic infiltration are seen (Figure 55 & 56).

Abstract

Foliar N and P content of olive trees have shown a gradual increase from the month of October till May. But gradual decrease in leaf K content occurred between the months of October to February, where after a gradual but continuous increase in its content was noted till the month of May. However, foliar Ca and Mg contents also registered an increase between the months of October to January, but thereafter, a continuous decrease in their content was evident till the month of May. Relatively higher N, P and K contents were estimated during non- cropped year as compared to the cropped year. But converse was true for Ca and Mg content. Among different cultivars maximum values of foliar N, P, K, Ca and Mg were found in Frantoio, followed by Leccino, while minimum values of leaf macronutrients were recorded in Ascolano. Thus maximum values of leaf N, P, K, Ca, Mg ensured regular bearing behaviour of the cultivar whereas deficiencies of these nutrients tended to induce erratic bearing behavior of the cultivar.

Introduction

The peripartum period, spanning from 3 weeks pre-calving to 3 weeks post calving, is a critical phase in a cow’s life. During this time, cows are susceptible to various diseases that can significantly impact their health, productivity and reproductive performance. Changes in metabolism and lack of optimum immunity have been closely associated with most of the transition period diseases. Hormonal changes in the early lactation results in drain in energy and nutrients rendering the animal in some degree of negative energy balance. Increased lipid mobilization in transition period has its role in fatty liver and ketosis directly.Metabolic stress in peripartum cows refers to the physiological changes that occur around calving, affecting energy and nutrient balance.

Peripheral nerves

The peripheral nervous system (PNS) is the part of the nervous system that lies outside the brain and spinal cord. It includes cranial nerves, spinal nerves and their roots and branches, peripheral nerves and neuromuscular junctions. In the peripheral nervous system, bundles of nerve fibres or axons conduct information to and from the central nervous system. The primary role of the peripheral nervous system is to connect the central nervous system to the bones, muscles and skin of the body trunk and the limbs and the organs to allow the complex movements and behaviour.

The peripheral nervous system is divided into the somatic nervous system and the autonomic (visceral) nervous system.

The somatic nervous system is associated with skeletal muscle voluntary control of body movents. It consists of afferent and efferent nerves. Afferent nerves are concerned with relaying sensation from the body to the central nervous system. The efferent nerves are responsible for sending out commands from central nervous system to the body, stimulating muscle contraction. This system is made up of nerves that connect to the skin, sensory organs and all skeletal muscles.

The autonomic nervous system is the part of peripheral nervous system that controls the visceral functions which occur below the level of consciousness. It consists of two divisions, the sympathetic nervous system and the parasympathetic nervous system.

Peritoneal Fluid Peritoneal fluid (PTF) is an ultra-filtrate of plasma. The amount of the fluid and its constituents depends on oncotic and hydrostatic pressures, vascular permeability, mesothelial lining integrity, and lymphatic drainage. In healthy animals, the amount of peritoneal fluid is negligible making its aspiration difficult. However, in large animals, a small volume (up to 5ml) can be aspirated. Volumes of 10ml or above may indicate a pathological process in the abdominal cavity, unless the animal is in late pregnancy. Indications for collection and analysis The collection and analysis of peritoneal fluid is important in the diagnosis of diseases of the peritoneum and the abdominal segment of alimentary tract .Increased accumulation of peritoneal fluid may be evident in congestive heart failure, peritonitis, nephrotic syndrome,

Botany: Periwinkles (Catharanthus roseus) belonging to the family Apocynaceae are evergreen perennials that produce bright blue flowers. They grow best in well-draining, moist soil and partial sun to full shade. They work well as sprawling groundcover or border plants and bloom from early spring to early fall. Periwinkles are often grown as transplants, but they can be started from seed about 10 weeks before the last frost with the proper care.

Varieties: Nirmal, Dhawal and Prabal

Soil and climate: It is suited to all types of soil and tropical climatic conditions. Well distributed annual rainfall of 100 cm or more is ideal for raising as a rainfed crop.

Seeds and planting: Propagated through seeds either by direct sowing or throughtransplanting.

Seed rate: 2.5 kg/ha : Direct sowing

0.5 kg/ha : Through seedlings

45 - 60 days old seedlings are transplanted at a spacing of 45 x 20 cm during June - July or September - October.
