Objective

1. To know the different types of fertilizer application methods applied in spices and condiments.

Methods of fertilizer application: The different methods of fertilizer application are as follows:

a) Broadcasting

1. It refers to spreading fertilizers uniformly all over the field.
2. Suitable for crops with dense stand, the plant roots permeate the whole volume of the soil, large doses of fertilizers are applied and insoluble phosphatic fertilizers such as rock phosphate are used.

Broadcasting of fertilizers is of two types

1. Broadcasting at sowing or planting (Basal application): The main objectives of broadcasting the fertilizers at sowing time are to uniformly distribute the fertilizer over the entire field and to mix it with soil.

Fertilizer is a substance of natural or synthetic origin, applied to soils or to plant tissues (usually leaves) for the supply of one or more nutrients essential to the plant. It is classified in two types, inorganic fertilizers and organic fertilizers. Both the fertilizers play major role to the crops if they are properly and appropriately applied. To obtain maximum benefits, it is important to apply fertilizers at an appropriate time, amount and in a precise manner. The method of fertilizer application should be selected appropriately taking into consideration the age and stage of crop plants, their root extensibility, type of orchard management, kind and amount of fertilizers to be applied. The fertilizers should be given over the area of crop plants, where their active roots are spread. In fruit trees, fertilizer should be given in restricted area i.e. in the surrounding area of about 1 to 1.5 m away from the trunk of the trees in active root zone.

When to apply the fertilizers?

Majority of the crops require nutrients at different stages like growth & development, flowering and fruit setting time. In fruit crops, stages like new flushes emergence, floral buds differentiation and fruit development require more nutrients. Time of application of fertilizers may also vary depending on types of fertilizers, need of the crops, soil and climate.

Q.1 SRSWOR scheme is better (more efficient) them SRSWR scheme.

Q.2 The sampling variance of sample mean under SRSWOR scheme is more than that in SRSWR scheme.

.3 The sample variance s2 is an unbiased estimate of population M.S. (S2 ) in case of SRSWOR scheme.

Q.1 The replicated experiment designed to compare a number of parent plants w. r. to some attribute under study is known as “Progeny row trial?

Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. Alkaloids showed quite diverse medicinal properties (Rates, 2001). Many of them possess local anesthetic properties, but their practical use is limited for clinical purposes (Hesse, 2002). Morphine is one of the most known alkaloids isolated from Papaver somniferum (opium poppy), which had been used and still is for medical purposes. This alkaloid is a powerful narcotic which is used for the relief of pain, but its usefulness is limited because of its addictive properties.

Historical Development of Soil Science/Agriculture

Francis Bacon (1561-1624 A.D.): Found the water as nutrient of plants.

Van Helmont (1577-1644): Give the ideas about the role of soil as a simple source of water and minerals for the plants.

Technical Term                        Definition

Hydrology                               Hydrology is the science of water derived from Greek wordî hydro + logosî i.e., water + sciences and hance defined as the science which deals with occurrence, distribution and circulation of atmospheric water through unending Hydrologic cycle.

Technical Term                    Definition

Canal Irrigation System      The system in which irrigation water is supplied through irrigation canals network (main canal, submain canal, distributaries, and

                                            minors) from source of water (reservoirs) to point of application (agricultural lands)

Classification of market

There are several bases on which markets are classified.

a. On the basis of location

On the basis of the place of location or operation, markets are of the following types:

Village market

A market which is located in a small village, where major transactions take place among the buyers and sellers of a village, is called a village market.

Primary markets

• These markets are located in big towns near the centres of production of commodities. In these markets, a major part of the produce is brought for sale by the producer-farmers themselves. Transactions in these markets usually take place between the producers/farmers and traders.

Export and import- an overview

The major thrust of livestock development strategy in India has been on achieving self-sufficiency in livestock products through import substitution. Several initiatives were taken to develop the Indian livestock sector in the past and India emerged as the largest milk producer in the world and it is also one of the largest producers of other livestock commodities. However, the economic policy reforms and economic liberalization triggered in 1991 have widened market opportunities for the livestock sector. The global demand for livestock products is also on the rise. Such developments offer an opportunity for India to increase its livestock exports, especially for products like bovine meat, whose domestic demand is low. With improved domestic production and marketing efficiency, better access to expanding world market, India has the potential to become more competitive and may augment port of livestock products. The export and import details reveal that there has been a steady increase in the value of imports and exports of livestock and livestock products in India.

Scheme

The needy livestock farmer visits the banks in the local area and enquire with the bank manager about the livestock projects and after having discussion with him, he visits the technical expert. A scheme can be prepared by a beneficiary after consulting local technical persons of State animal husbandry department, DRDA, SLPP, etc. livestock co-operative society/union/federation/commercial livestock farmers. If possible, the beneficiaries should also visit progressive livestock farmers and government/military/agricultural university livestock farm in the vicinity and discuss the profitability of livestock farming. A good practical training and experience in livestock farming will be highly desirable. The livestock co-operative societies established in the villages as a result of efforts by the Livestock Development Department of State Government and National Livestock Development Board would provide all supporting facilities particularly marketing of fluid milk. Nearness of livestock farm to such a society, veterinary aid centre, artificial insemination centre should be ensured. There is a good demand for milk, if the livestock farm is located near urban centre. The scheme should include information on land, livestock markets, availability of water, feeds, fodders, veterinary aid, breeding facilities, marketing aspects, training facilities, experience of the farmer and the type of assistance available from State Government, livestock society/union/federation.

Procurement is acquisition of goods and services.
Procurement includes:
• Planning the acquisition
• Planning the contracting
• Requesting proposals 
• Selecting a vendor
• Administering the contract
• Closing the contract 

Planning the acquisition

It is based on goals of an enterprise acquisition varies – depends on what, when and where to produce. Based on these factors acquisition requirements are arrived.

The word cereal was derived from Ceres, the name of the Roman goddess of harvest and agriculture. Cereals are grasses (members of the monocot family Poaceae, also known as Gramineae) cultivated for the edible components of their grain (botanically, a type of fruit called a caryopsis), composed of the endosperm, germ and bran. Cereal grains are grown in greater quantities and provide more food energy worldwide than any other type of crop and therefore they are called staple crops.

System of Rice Intensification (SRI) was first developed in Madagascar during the 1980s SRI uses less inputs. It uses less seed, water, chemical fertilizers and pesticides but uses more organic manures. Rice grown with SRI technology has large root volume, profuse and strong tillers with big panicles, more and wellfilled spikelets with higher grain weight

Maize is one of the world’s leading crops cultivated over an area of about 194 million hectares with a production of about 1147 million tonnes of grain (2020). Among the maize growing countries, USA has the largest area followed by China, Brazil, Argentina, Ukraine and India. In respect of production also USA stands first followed by China. Regarding average yield per hectare USA ranks first followed by China. The average maize yield in India is only 3065 kg per hectare which is much lower than most of the maize growing countries of the world.

History of jute in India: In Mahabharata times the mention has been made regarding Jute garments as pattagam (patta produced) for jute fibre products and kitajam (insect produced) for silk products. In Ain-e-Akbari, there is mention of sack cloth made from jute, in Rangapur district.

Forages: The term forages denote plants that are used for feeding the animals that are cultivated in the farm, or it may be a wild used for stock feeding grown for the vegetative purpose. The vegetative phase is encouraged and the reproductive phase is suppressed.

The proposal presented takes into account the rationale of using natural source of immunity, discarding any preservatives or artificial flavors and additives. Collection of fresh produce followed by processing of fruits and vegetables, in the form of a veggie mix slushy which is ready to eat, ready to cook and easy to digest, through the use of sustainable retorting technology. The proposal takes into account the major problems regarding food for the elder like lack of digestion, in sufficient appetite, lack of value in terms of vitamins and minerals of food, also targeting the notion of feeling sick by taking multi vitamin and immunity tablets on a regular basis.

Diverse categories of Food Products such as canning, preservation of fruits and vegetables, processing of poultry products, dairy goods and many more present different challenges for wastewater disposal and regular use of water. A significant source of environmental pollution is the dissipated water generated from food product development and other agricultural tasks. This waste is being considered the most strenuous and requires a high amount of capital to convert this waste into reusable waste and the main reason behind this is different nutritional components such as inorganic and organic carbon compounds, nitrogenous elements, suspended and dissolved solids, high amount of biochemical and chemical oxygen demands (BOD & COD).

As a result of a number of health advantages provided by functional foods, a substantial rise in their popularity has been seen in recent years (Keservani et al., 2010).

Most of the starch sources are cereals (40 to 90%), tubers (65 to 85%), roots (30 to 70%), legumes (25 to 50%) which contain nearly 70% of starch on dry basis (Santana & Meireles, 2014). Major application of starch is seen in food production, where it is used as a thickening agent, for stabilization, adsorption, gelling, for binding aromatic compounds and as a film forming agent as well (Subaric et al., 2007). About 0.8-3.2 tons of CO2 per ton of plastic can be saved by using starch-based plastics (Patel 1999).

A number of quality management tools are being used in food processing industry. Often selection of such tools are tough as it involves several factors for decision-making. The problem of choice of quality management and tools can be solved by selection on the basis of the objective decision making process rather than on the opinion of the decision makers (Sukkarn and Thawesaengskulthai, 2015).

Wood apple (Feronialimonia) commonly known as Bael in various Indian sub-continent languages is the most under-utilised fruit despite of its aromatic flavor, high nutritional components and important medicinal values. Reason may be due to challenge in harnessing the pulp from the fruit. It is considered under seasonal fruit but it has long duration of shelf-life as compared to other fruits.The physic-chemical characteristics revealed that it has high shell weight of 55.67% as compared to pulp weight of 43.77% (Devi et al. 2018).

Vegetable oils and fats play a very important role in our diet. They provide essential fatty acids which are precursors of important hormones such as prostaglandins. They control many physiological factors such as blood pressure, cholesterol and reproductive system [1]. Coconut oil is a popular vegetable oil obtained from kernel of fruit coconut (Cocos nucifera). It is liquid at room temperature and bland in taste. Coconut oil is extensively used in cooking purpose in coastal tropical regions although it has been used in abundance for its medicinal properties.

Phytoplankton populations are important in shrimp ponds because they aid in shrimp nutrition and the removal of excess nutrients from the pond environment. They can be beneficial or have potentially negative consequences, depending on how they are managed.

All the plant biochemical processes are sensitive to change in temperature. Freeze or low-temperature stress in plants becomes lethal when the temperature is lowered beyond a critical threshold for a sufficient duration to cause irreversible damage to plant growth and development. This stress influences countless biochemical reactions which have certain temperature optima for their proper functioning.

As the vulnerability of different plant species to frost and low-temperature stress is quite variable, the symptoms are also variable, therefore. The development of visual symptoms depends largely upon the plant genotype, growing environment and tissue type being exposed to low-temperature stress.

The problem of frost damage to the crops is as old as agriculture is. Earlier, crop production was undertaken only as per the geographical distribution of the plant species and the cultivation of crops in non-conventional areas was not there. Later, with the expansion of agricultural activities, a number of introductions were made in the non-conventional areas. 

When avoidance or tolerance of frost is not possible and frost damage is inevitable, the active methods of frost protection are the way out for the protection of the fruit plantations. The methods which are employed just before or during a frost event for avoiding freeze damage are called Active Frost Protection Methods.

Liver is the largest exocrine gland located in right side of the abdominal cavity
obliquely from lumbocostal angle downward and forward to intercostal space,
about 3-4” (10 cm) above the abdominal floor.

The major functions of the musculoskeletal system to provide support to organs and help in physical activities including locomotion, prehension, and
mastication. The clinical manifestations of the diseases of muscles, bones and joints are much in common, and are generally characterized by lameness,
failure of support, in coordination of movement and deformity.

Anorexia in dogs with heart failure is very important clinical sign of concern as continued anorexia leads to weight loss and cardiac cachexia. Cardiac cachexia in dogs is the main reason that contributes to an owners’ decision to opt for euthanasia. It is therefore much more important to understand the various factors that lead to anorexia in dogs having heart failure. 

Heart failure is the end stage of cardiac diseases. It occurs in pet birds when cardiac output is insufficient and unable to maintain arterial blood pressure. In birds right side heart failure is more common as compared to left heart failure.

The application of (VCRS) Vapour compressor refrigeration system is in the air conditioners (window, split, central or precision), car air conditioners, domestic refrigerator etc. The different parts of a domestic refrigerator are: in the hermetical sealed compressor, air cooled condenser, capillary tube, thermo expansion device, filter, rotameter, solenoid valve, temperature control sensor.

Thermal stress arises whenever there is some increase or decrease in temperature of a body which causes either expansion or contraction in the dimension of body. If body is free to expand or contract, with the rise or fall of temperature, there exist no stress in the body. But if deformation of the body is partially or completely resisted then stresses are set up in the body which is known as Thermal Stress. However amount of stress induced in partially prevented deformation will be small than in case deformation is totally prevented.

The initial symptom of Alternaria brassiciola appears as small, dark colored spots which enlarge rapidly to form circular lesions. Under humid conditions a bluish velvety fungal growth is seen in the centre of these spots. Spots caused by Alternaria brassicae are almost similar to those produce by Alternaria brassicicola but are comparatively smaller and lighter in colour. When many spots are formed on the leaves, the leaves turn yellow and dry prematurely. Formation of pods and seeds are adversely affected.

It is a very common disease of mango. It is otherwise known as blossom blight, leaf spot, twig blight or wither tip.

The disease attacks all the growth stages of plant affecting all above-ground parts. Plant covered with powdery patches leads to distortion, malformation and discolouration of leaves especially young leaves. Powdery patches gradually turn to grey and fi nally dark colour. Affected fl ower fails to develop fruit. Young berries turn black, irregular in shape and develop cracks. Sometimes berries ripe partially and rot. Vines get wilted.

It is a serious disease of apple which not only reduces the quality and size of fruit but also cause premature fruit drop and defoliation. Fruit loses its marketability due to poor quality. It also reduces storage time and cause loss up to 70%.

In light of the high population of nematodes, N.A. Cobb (1915) who is considered to be the father of American Nematology, provided a dramatic description of the abundance of nematodes. He stated, “if all the matter in the universe except the nematodes were swept away, our world still would be dimly recognisable.

Potato is one of the most important vegetable crop grown in India. It thrives best in cool climate. Therefore it is a summer crop in the hills and a winter crop in plains.

In general, germination of onion seeds is poor, and, in the case of old seed stocks, this problem is severe. Seeds soon lost viability in the ordinary storage state. However, cold storage conditions significantly increase the viability of seeds.

In several cucurbits as well as other crops, BER is a physiological condition found (for example, tomato, brinjal and pepper). It typically occurs as a general rot at the flowering end of rising fruit. Usually, the blossom end rot is the result of inadequate or uneven irrigation, high humidity, or other variables that slow the flow of water through the plant. Slow water movement may also result in temporary calcium deficiencies leading to blossom end rot as calcium is added into the plant with the transpiration stream.

This is one of the most serious difficulties in mango farming since it makes mango agriculture less rewarding for farmers. In one year (a year) and very little or no harvest next year, mango trees appear to bear huge crops (off year). This bieniality is therefore also present in normal ranges (Singh, 1990). 

Ordinarily, fruit bears a single crown, but fruit bears more than one in some cases. The top of the fruit will therefore be smooth and wide and the fruit will not be ideal for canning. These fruits have an insipid taste and are corky. It is intended to be an inherited character, often found in the Cayenne group to which the Kew variety belongs.

A well planned projects requires pre-feasibility study to explore the opportunity to find out problems, avenues of co-ordination etc. A government being a regulation spells out priotize for national and regional economy and by the frameworks for resource allocation.

It is a process by which a act of predetermined activities is carried out in a planned manner, with a view to achieve certain establish objectives.

To implement a project means to carry out activities proposed with the aim to achieve project objectives and deliver results and outputs. It is a highly complex process and it involves a relationship among several system and variables

ACID SOILS: Acid soils with pH below 6.5 are widespread. Main limitations of these acid soils are low pH, low CEC, low status of bases, especially Ca, Mg, and K along with toxicity of Al and Mn. Use of acidifying fertilizers aggravates this situation.

The aim of any good zoo should be to recreate the habitat from which the animal came as accurately as possible, with enough space to move around and enough stimulation so that they can behave naturally. Monkey cages should have plenty of branches for them to swing from and bird cages should have enough room so that they can fly. Some zoos hide the lionís or tigerís food so that they have to use their senses to explore and find it.
