INTRODUCTION

For survival of young seedlings and rooting of cuttings it is essential that they maintain a healthy water and air balance especially to make up the water lost in transpiration. Water stress within the cuttings hinders metabolic activities and cell regeneration and consequently initiation of roots. So medium should be such that it provides adequate water required for rooting and growth. Also these substrates must provide initial nutrients necessary for plant growth. These should also contain micro-organisms that seedlings may need.

INTRODUCTION

The propagation of plants has been one of the fundamental occupations of mankind since beginning of civilization. Plant propagation involves the application of specific biological principles and concepts in the multiplication of plants for useful purposes. The present day plant propagation industry is large and complex and involves not only the group that multiplies the plants for sale and distribution, but also a large group of industries that provide services, sell the product, is involved in regulation, provides consultation carries on research or is involved in teaching. The key person with in this complex, however, is the plant propagator who possesses the knowledge and skill either to perform or to supervise the essential propagation tasks for specific plants.

INTRODUCTION

Plant propagation involves three main aspects: knowledge of mechanical manipulations and technical skills which constitutes the art of propagation; knowledge of plant growth and structures which constitutes science of propagation and knowledge of different kinds of plants and their methods of propagation. The basic objective of plant propagation is to increase the number of desirable types and to preserve the essential characteristics of the plant. Generally, sexual propagation or the seed propagation is used to raise the seedling rootstocks on which to graft or bud the desirable types. The clonal rootstocks are multiplied through vegetative means- layering, cutting etc. Various sexual and asexual methods such as use of seeds, apomicts, specialised plant parts, cuttings, layers, grafts and buds are employed to multiply plants of different fruit crops. In this chapter, the techniques used for raising rootstocks and multiplying the desirable types of different fruits have been discussed.

INTRODUCTION

With the change in world scenario from plentiful resources to limited with population increasing geometrically, shrinking land and climate change, the pressure on agriculture is mounting continuously. Meeting the nutritional requirements of population by optimum supply of food is the pre-requisite for sustainability of life under such conditions. Rapid urbanization is causing scarcity of cultivable land. Therefore, the productivity per unit area of the crops needs to be increased manifold. Horticulture, in general, has attained a pride status in the field of modern agriculture. However, radical changes are expected in horticultural practices in near future as the situation in terms of area as well as production is not as comfortable as the food grain production.

Water is the most critical component of life system. Irrigation plays vital role in rising and stabilizing yield and maintaining quality of fruit crops grown in tropical or sub-tropical climate. Micro irrigation is one of the modern and advanced methods of irrigation which is becoming popular in areas having problems like water scarcity and poor quality of water. Since the competition for water between agricultural and non-agricultural sector is increasing day by day, the efficient management of water resources is very essential to meet the water requirement. It is anticipated to reduce water use for agriculture by 70% in the coming decade, where the present day share is 80%. Demand for water is increasing in non-agricultural sectors like industry, energy, domestic use etc. Hence, policy makers and researchers consider water as the main obstacle for growing enough food crops in the coming years. In India where population is increasing at alarming rate, the area under irrigation should go up from 60 million hectares to 114 million hectares by the year 2050. In this context, micro irrigation plays a major role under limiter water agro ecosystem.

Introduction

India is a rich center of plant diversity due to varied climatic conditions as well as soil qualities which provide a better platform for the diverse plant groups. In India around 45000 plant species are spread over the area (Mayers, 1988). These plant species multiply and produces the new plant. The multiplication of plants is termed as propagation and the art of propagation is as old as civilization of human being. The history of civilization began with the propagation and growing of plants. Plant propagation was in practice in pre-historic period. However, the propagation process has got commercial popularity only recently. The success in plant propagation depends on a thorough knowledge of the growth of plants, choice of suitable method and technical skill. In nature, plants multiply naturally to perpetuate themselves. Now-a-days, propagation practices have been totally modernized and became advanced from field to in vitro. Variation in plant propagation can be observed in the nature like some plants are producing many seeds for future generation with their unique type of dispersal mechanism. Among a large

Introduction : Need to Change

During the era of Green Revolution, India remarkably achieved self-sufficiency in food production with the introduction of high-yielding varieties, extension in the irrigated cultivable land, high use of chemical fertilizer such as Urea and other sources of NPK fertilizers and increase in cropping intensity.During these processes, relative contribution of organic manures as a source of plant nutrients declined substantially. Due to heavy application of chemical pesticides an increase in resistance of insect pests has also been noticed for most of the regular used plant protection chemicals. Health hazards associated with intensive modern agriculture, such as pesticides residues in food products and groundwater contamination are matter of concern. In the progress of green revolution technologies and chemical dependent nutrient management has declined the overall productive capacity of the soil due to no judicious fertilizer use. Such concerns and problems faced by modern-day agriculture gave birth to new concepts in farming, such as organic farming, natural farming, biodynamic agriculture, donothing agriculture, eco-farming, etc. The essential feature of such farming practices imply, i.e., back to nature.

Introduction

There has been a slow evolution of information technologies in fruit crop production as innovators combined their prior field experience with an attitude of learning by doing while looking for practical applications for farm management. As a suite of technologies became available for use in agriculture production, a new management strategy that combined information with decision making became known as Precision farming. Precision farming is the emerging technology which involves maintaining of crop inputs on site specific basis with reducing waste, increasing the profits and maintaining the quality of environment. The main tools involved in this are Geographical Information System (GIS), Variable Rate Technology (VRT), Global Positioning System (GPS), Yield Monitoring and Remote Sensing.

Abstract

Horticulture crops play significant role in improving the productivity of land, generating employment, enhancing exports, improving economic conditions of the farmers and entrepreneurs and providing food and nutritional security to the people. For better management of the existing crops and to bring more area under horticulture crops, updated and accurate database is necessary for systematic planning and decision making. Remote sensing (RS) is an advanced tool that aids in gathering and updating information to develop scientific management plans. Many types of sensors namely microwave radiometers, laser meters, magnetic sensors and cameras collect electromagnetic information to derive accurate, large-scale information about the Earth’s surface and atmosphere. Because these data and images are digital, they can easily be quantified and manipulated using computers. RS can be used in efforts to reduce the risk and minimize damage. The same data can be analyzed in different ways for different applications. A number of studies were aiming at identification of crop, area estimation, disease and pest identification, etc. using satellite data in horticulture. The potential use of RS techniques in Horticulture is briefly reviewed in orde

Introduction

In India, Fruits and vegetables comprises nearly 90% of the total horticulture production. India is now the second largest producer of fruits and vegetables in the world and leader in several horticultural crops, namely mango, banana, papaya, cashewnut, arecanut, potato, and okra (National Horticulture Board, 2015). The total area occupied by horticultural crops in India was 23.69  million ha and total production was 283 million tonnes in 2015-16 (Source: Ministry of Agriculture and Farmers’ Welfare). Different horticultural crops like fruits, vegetables, spices, medicinal plants and plantation crops comprises a large chunk of the total crop sales value of the country and also secures nutritional security of the persons of the country. For systematic and efficient management of existing crops and to bring more area of the country under the cultivation of horticultural crops to increase overall horticultural production in term of time and area, a database must be created for decision making and planning.

Abstract

Organic farming is a method of crop and livestock production that involves much more than choosing not to use pesticides, fertilizers, genetically modified organisms, antibiotics and growth hormones. Organic fruit production essentially excludes the use of many inputs associated with modern farming, most notably synthetic pesticides and fertilizers. Organic agriculture, the innovative farming system can build-on and enhance the traditional knowledge and practices of local and indigenous communities. Indigenous Knowledge can be broadly defined as the knowledge that anindigenous (local) community accumulates over generations of living in a particular environment. ITK in fruit production is important for reducing the cost of cultivation, reducing the pollution and also the natural resource base. It is very important to understand these age old practices to address the local problems and to document it before is vanished away.

Introduction

Any kind of garden established on the roof top of building is known as roof garden, which provides the opportunity to cultivate the quality vegetables, fruits and flowers in home. In this system plants and grasses are grown on a nutrition medium placed above a waterproof membrane. Roof gardening is mostly adopted in urban areas. It uses for decorative benefit, roof plantings make available food, manage temperature, hydrological remuneration, architectural improvement, habitats  for wildlife, frivolous opportunities, and in large scale it may even have ecological benefits (Louise, 2009). This considerably increases human health as adding organic cultivation.

Introduction

Controlled perpetuation of plants is known as plant propagation. Plant propagation can be broadly classified in two types: sexual and asexual. In sexual propagation, the fusion of male and female gametes gives rise to a new plant, whereas in asexual propagation which is also known as vegetative propagation, the development of new plants takes place without the fusion of male and female gametes, that is, the new plant develops from vegetative plant parts. Various techniques of asexual propagation are adopted in plant propagation, such as: grafting, budding, layering, cutting, etc. So far cutting and layering are concerned; the new plants are developed on their own root system, but in grafting and budding on the others’ root system. It means that in these two techniques (grafting and budding), two plant parts are joined to form new plants; the one which forms the root system is known as rootstock and the one forming the shoot system is known as scion. Plant propagation is both a science and an art. The science of plant propagation requires knowledge of plant physiology, nursery cultural practices, and characteristics of the particular plant that you want to grow. The art of plant propagation cannot be taught in a book or classroom, however, because it consists of specific technical skills that must be acquired through innate ability or experience and often requires a certain feel.

SEED GERMINATION

Germination is the growth of a plant contained within a seed; it results in the formation of the seedling, it is also the process of reactivation of metabolic machinery of the seed resulting in the emergence of radicle and plumule. The seed of a vascular plant is a small package produced in a fruit or cone after the union of male and female reproductive cells. All fully developed seeds contain an embryo and, in most plant species some store of food reserves, wrapped in a seed coat. Some plants produce varying numbers of seeds that lack embryos; these are called empty seeds and never germinate. Dormant seeds are ripe seeds that do not germinate because they are subject to external environmental conditions that prevent the initiation of metabolic processes and cell growth. Under proper conditions, the seed begins to germinate and the embryonic tissues resume growth, developing towards a seedling.

Introduction

Sensors are the key components for enabling any IoT(Internet of Things) application. The concept of IoT came as early as 1990 but the practical implementations of the IoT technology is actually becoming possible as the cost of the devices that are needed to create any IoT application have reduced. Sensors are one of the major hardware components needed to form IoT systems and decrease in its price has given a forward leap in developing IoT applications. Sensors have to be uniquely identifiable devices with a unique device ip address so that they can be easily identifiable over a large network. These have to be active in nature which means that they should be able to collect real time data. These can either work on their own (autonomous in nature) or can be made to work by the user depending on their needs (user controlled).

INTRODUCTION

Soil is one of the most important factors associated with the success or failure of fruit production. Orchard soil management refers to those practices in the soil that aim at getting maximum productivity/production of quality fruits within the limits of soil, water and fertility management over the years. The decision regarding the practices of orchard management should always be taken well in advance before planting of an orchard. The practices for orchard management should be executed in a timely manner during the lifetime of the orchard. An efficient orchard management system always ensures higher return to the grower. However, no single management practice can be recommended for all orchards. The management systems varies from orchard to orchard, locality to locality, soil to soil, from one set of climatic conditions to another set of climatic conditions etc. These systems also have their own merits and demerits. Thus the choice of best suitable system depends on many factors such as climate, topography, rainfall, tree spacing, planting system/ orchard design, root depth of tree, economic condition of orchardists, fertility status of soil and type of main fruit crop etc.However, it should be combined with pruning, nutrient and water management, provision for pollination, fruit thinning and disease and pest management in order to obtain desirable tree growth and vigour with the aim to promote precocity with high productivity. The objectives of an ideal soil management system should be:
