The Indian Agronomics is predominantly dependent on the vagaries of monsoon. Add to it, the problem of soil health-related issues i.e. low fertility & productivity, salinity, alkalinity, nutrient imbalance, etc., which get further aggravated from the imbalanced fertilizer applications, excessive use of irrigation water, pollution from high pesticide usage & other sources, untimely & inefficient land tillage to name a few. All these factors directly and indirectly affect the agricultural output.

The other major issue involved is the ever-increasing pest & disease incidence, which reduces the crop output to a large extent. The only reliable option to tackle this issue is to use pesticides effectively with the desired quantity. Here, the farmers must understand the technical aspects of the usage of pesticides like; dosage, frequency, effects of toxic & hazardous chemicals on the environment, residual effect on the farm output, etc. as these are related with the sustainable agriculture as well as health related problems of all the living beings including Humans.

Nutrition


An important aspect on how nutrients are essential for plant life was shown by Baron Justus Von Liebig, a German scientist in the mid-19th century. He stated, "we have determined that a number of elements are absolutely essential to plant life. They are essential because a plant deprived of any one of these elements would cease to exist. . . ." He also authored the term "law of the minimum," which states that "plants will use essential elements only in proportion to each other, and the element that is in shortest supply in proportion to the rest will determine how well the plant uses the other nutrient elements." Knowing that the nutrients required to grow plants is only one aspect of successful crop production, optimum yield also requires the knowledge on the rate to apply, the method and time of application, the source of nutrients to use, and how the elements are influenced by soil and climatic conditions.

Essentially, there are 16 nutrient elements required to grow healthy crops. Three essential nutrients; Carbon (C), Hydrogen (H) and Oxygen (O2)-are taken up from the atmospheric Carbon Dioxide (CO2) and Water (H2O). On the other hand, the other 13 nutrients are taken up from the soil and are usually grouped as; Primary Nutrients, Secondary Nutrients and Micronutrients.

Primary Nutrients
Nitrogen (N), Phosphorus (P) and Potassium (K)-are commonly found in blended fertilizers such as 10-10-10, or equivalent grades. Primary nutrients are utilized in the largest amounts by crops, and therefore, are applied at higher rates than secondary nutrients and micronutrients.

The Primary Nutrients & Plant Growth

Secondary Nutrients
Calcium (Ca), Magnesium (Mg) and Sulphur (S) - are required in smaller amounts compare to the primary nutrients. The major source for supplementing the soil with Calcium and Magnesium is Dolomite Lime, although these nutrients are also available from a variety of fertilizer sources. Sulphur is available in fertilizers such as Potassium and Magnesium Sulfate, Gypsum (calcium sulfate) and Elemental Sulphur.

The Secondary Nutrients & Plant Growth

Micronutrients
Iron (Fe), Manganese (Mn), Zinc (Zn), Copper (Cu), Boron (B) and Molybdenum (Mo) are required in even smaller amounts than the secondary nutrients. They are available in Manganese, Zinc and Copper Sulfates, Oxides, Oxy-Sulfates and Chelates, as well as in Boric Acid and Ammonium Molybdate.

Disease Management


Field crop production practices continue to change as growers evaluate new techniques and technologies to increase productivity. Plant diseases, unfortunately, present a challenge to producers by continuing to limit yields in all the crops. There are a multitude of crop production management decisions that producers must make throughout a growing season. Many of these decisions can influence the impact of plant diseases on yields.

Proper cultural practices that favor the development of vigorous seedlings and hardy, mature plants will help manage diseases or lessen their detrimental effects. Disease management is also aided by good agronomic practices such as proper seeding rates and seeding dates, balanced fertility, crop rotation, tillage, and weed control. In other words, the healthier a plant is, it is better able to still be productive, even in the presence of plant pathogens. Many disease-management decisions are made before planting. In most farming systems, the producer can do little once a disease becomes severe in his field.

Therefore, prevention is the first, and usually the only line of defence against disease. It is rarely economical to treat acreages with fungicides. The primary fungicide application method in field crops is seed treatment, where extremely low rates of active ingredient per acre are applied directly on the seed before planting in the soil. Diseases are the direct result of three critical factors coming together at one time, which occurs when a pathogen attacks a susceptible plant under environmental conditions that favor the infection and growth of the pathogen within the plant.

The most common disease-causing agents or pathogens are; fungi, bacteria, viruses, and nematodes. The most critical environmental factors are soil and air temperature, moisture as rain or dew, relative humidity, soil fertility, and pH. Serious disease can occur on susceptible cultivars when environmental conditions are right for the spread of an aggressive pathogen. For instance, the fungus that causes leaf rust of wheat produces severe yield losses on susceptible varieties when spores are blown in on wind currents. Susceptible varieties may have as much as a 50 percent yield loss, whereas resistant varieties may have little or no yield loss.

The cornerstone to successful disease control is correct identification of the disease related problems on your farm. Producers facing specific disease problems can fine-tune their disease-control strategies to those few diseases encountered each year. Those with little experience identifying diseases should seek help from competent sources, such as SAU's, Research Institutes, KKV's, etc.

Insect Management


The best method for the management of insect pests in the field crops will be Integrated Pest Management (IPM).

IPM is a sustainable approach to managing pests by combining biological, cultural, mechanical and chemical tools in a way that minimizes economic, health and environmental risks.

Principles of IPM
  • Identification of key pests and beneficial organisms
  • Defining the management unit, the Agro-ecosystem
  • Development of management strategy
  • Establishment of Economic thresholds (loss & risks)
  • Development of assessment techniques
Tools of IPM
  • Monitoring:
  • Pest resistant varieties:
  • Cultural pest control:
  • Mechanical control:
  • Induced Resistance:
  • Biological control:
  • Chemical control:
