Effective application of pesticides depends on many factors. One of the more important is to correctly calculate the amount of material needed. Unless you have the correct amount of pesticide in your tank mix, even a correctly calibrated sprayer can apply the wrong rate.

Manufacturers provide application rate instructions on every pesticide label. Due to the variety of ways in which these recommendations are stated (such as lbs. of active ingredient (a.i.) per acre, lbs. of formulation per 100 gal. of spray, or ozs, of a.i. per 1,000 sq. ft.) it is often necessary to adapt the recommendations to different areas and volumes, or even other units. Sometimes the amount of active ingredient must be converted to the amount of actual product. This process can be very confusing.

This chapter deals with the maintenance, repair, safety and trouble shooting of agricultural implements, equipment and machinery.

Routine maintenance reduces repair bills and extends the life of equipment. Good maintenance practices are essential for efficient operation of all types of farm machineries. Effort spent in this area of farm management is more than repaid by the consistent, reliable operation of machinery, reduced fuel bills and extended life of equipment. Maintenance of farm machinery is complicated by the usage pattern of short spells of intense activity, followed by periods of non-use or storage.

During the “standing” or non-use periods chemical interactions between metals and fluids can cause more damage than normal wear and tear from active usage. This must be considered in planning machinery maintenance.

5.1. Types of farming

Arable: Crops.

Pastoral: Animals.

Mixed: Crops and animals.

Subsistence: Grown just for the farmer and his family

Commercial: Grown to sell.

Intensive: High inputs of labour or capital usually small.

Extensive: Low inputs of labour or capital.

Sedentary: Permanently in one place.

Nomadic: The farmers move around to find new areas to farm.

Little leaf of cashew (Anacardium occidentale L.) is caused due to the deficiency of zinc. The leaves remain small in size giving rosette appearance.

The concept of capacity development is defined in various ways. Broadly, it is defined as a process by which skills, and knowledge are built, utilized, retained and nurtured with a view to provide an entity responding to a development challenge. Two components that are vital in any plausible definition of the concept are human skills (the ability to perform a task) and institutions (effectiveness and efficiency of organizations, systems, processes and procedures).

Black Pepper and Pearl Millet Flour for Disease Control in Chickens: To treat a disease in chickens characterized by frothing at the mouth, frequent cackling, restlessness, and reduced food intake, 10-15 black pepper corns are ground and mixed with pearl millet flour and water to form small pellets. These pellets are fed to the chickens to increase body heat and help eliminate the disease (Sabarkantha, Gujarat) (Parmar, 1992a).

Use of Garlic Against Pulorum in Poultry Birds: To cure chicks affected by Salmonella pulorum, one or two peeled cloves of garlic (Allium sativa) are soaked in a cup of water for 12 hours. The water is then given to the chicks to drink, curing them in two days (Dahod, Gujarat) (Khant, 1999).

Poultry Disease Management: For treating an unidentified disease in poultry birds that kills them within a few days, tribals use various plant-based remedies:

1. Bark of ‘beda’

2. Small pieces of onion

3. Grains of paddy smeared with kerosene

4. Tuber of ‘dev-alad’ (Curcuma spp)

Moisture Content
 
Two maximum moisture levels are provided to meet different climatic conditions and marketing practices. Lower values in the first column are suggested for countries with tropical climates or when long-term (more than one crop year) storage is a normal commercial practice. The values in the second column are suggested for more moderate climates or when other short term storage is the normal commercial practice.

The presence of nuts in the kernel is known as stubborn nuts or seedless or imperfect nuts and is frequent in coconut (Cocos nucifera L.). The nozzles impacted are oblong compared with the typical circular form of the nozzles and less than normal husk is generated. The often-breaking shell over the course of the development is the most typical feature of the barren nut. 

    Q.1.    How mastitis occurs in dogs? 
    Ans.    Mastitis in dogs initiates with the infection in the milk ducts of the dogs, where in the dog’s breast is enlarged as well as milk duct is blocked. The skin around the nipple might get cracked which might give a way to bacteria. In neglected cases it leads to cause gangrenous mastitis which is a severe form of mastitis in dogs.

    Q.2.    What are common pathogens responsible for mastitis in bitch?
    Ans.    Staphylococcus spp., Streptococcus spp. and Escherichia coli.
 
    Q.3.    What are the characteristic features of milk cytology during mastitis in bitch?
    Ans.    Milk cytology will show the presence of erythrocytes, degenerated neutrophils and bacterial agents.

    Q.4.    What characteristic physical changes of milk are seen during mastitis in bitch?
    Ans.    The viscosity of milk is increased and the colour of milk will be yellow to brown depending on the amount of blood and purulent exudates present.

Recommended Duration for Slinging Large Animal

Aim: To know slinging duration for large animal.

Indication: Downer cow, sternal redumbency, hypocalcemia, hypomagnesemia, limb or spinal injury, cases,related to parturition.

Start with a 1:2 molar ratio of vector: insert DNA when cloning a fragment into a plasmid vector. This ratio will vary with other types of vectors, for example, cDNA and genomic cloning vectors. The following example illustrates the conversion of molar ratios to mass ratios for a 3.0kb plasmid and a 0.5kb insert DNA fragment.

1. Botanical Name : Rubus paniculatus Smith

2. Family : Rosaceae

3. Common Name : Heart-Leaf Raspberry

4. Name in Indian languages: Kothalu, Kala hinsar (Hindi/Garhwali)

5. Description

Heart-leaf raspberry is a rambling climber, distinguished by its large ovate-heart-shaped, finely toothed leaves. It is a deciduous shrub, producing each year a cluster of scrambling, minutely-prickly, biennial stems up to 300 cm tall. The stems only produce leaves, and do not flower, in their first year of growth; forming flowering branches in their second year and then dying after fruiting. The plant is harvested from the wild for local use as a food, and sometimes also as a medicine.

6. Origin and distribution

It is native of Himalayas and found in the higher hills in Uttarakhand and Himachal Pradesh. It is also found in Nepal, Bhutan and China. The plants are at elevations from 1,500 - 2,900 metres msl. It is found in damp shady ravines to 1800 metres in Jaunsar and Tehri-Garhwal of Uttarakhand.

To achieve maximum possible irrigation efficiencies, there are two approaches.

Modernization of conveyance system down below the reservoirs upto government controlled outlet. Involves mainly the construction and maintenance of head sluices, main canals, branch canals, and distributaries (Modernization of supplier’s side or system level development works)

Modernization below the government controlled outlets upto the drains (Modernization of user’s side or farm level development works). Also known as On-Farm Development Works (OFD).

Demonstrations
Demonstration means showing by doing. The basic principle of Demonstration is learning by seeing and doing. The concept of demonstration was given by Dr. Seeman A. Knapp. Farmers like to see how a new idea works, both purposes can be achieved by means of a farm demonstration. A good, practical demonstration is an invaluable method in extension work. The demonstration is a particularly powerful method to use with farmers who do not read easily. There are two principal types of demonstration used by extension agents - method demonstration and result demonstration.

Vultures are obligate and highly efficient scavengers. They are keystone species providing important ecosystem services, but their adaptations to save energy, gorge themselves up to one third their body weight at a time, survive easily without food for up to a fortnight, conserve energy by using soaring and gliding flight, are just some of the unique and important characteristics of these magnificent birds. A highly efficient digestive system helps in extracting nutrients from otherwise non-nutrient sources like hide, tendons, and even bones. Vultures have been instrumental in keeping India clean and safe from disease outbreaks. A bird which is unaffected by multiple disease-causing micro-organisms helps to rid the environment from disease pandemics and epidemics. However, since the mid 1990ss these robust birds with a life span of 40-60 years, have declined drastically, from tens of millions to a few thousand currently, a decline of around 99%. For the formerly most abundant of these vultures, the white-rumped vulture, declines already happened by 99.9% in just 15 years! These declines led to multiple problems including increases in feral dog populations, economic and social losses and most importantly, 5,00,000 human deathsin five years,as a direct cause of the decline of vultures. The main cause of the vulture declines has been scientifically proven to be due to the use of veterinary diclofenac in cattle, their major source offood. Although veterinary diclofenac was banned since 2006, the drug has remained in the cattle carcasses at lower levels and new vulture toxic drugs have been discovered.
