ASRB NET · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Plant Sciences (agronomy, genetics and plant breeding, plant pathology, entomology, horticulture, plant physiology)

  • Draft a 10-item self-quiz on crop production practices for cereals, pulses, and oilseeds, and verify each answer against a standard textbook.

Your checkpoint

A 2-page genetics and physiology cheat sheet plus an error log of at least 40 solved practice items.

Week 2

Plant Sciences (agronomy, genetics and plant breeding, plant pathology, entomology, horticulture, plant physiology)

  • Compare the diagnostic symptoms of at least 12 major crop diseases and group them by pathogen type (fungal, bacterial, viral).

  • Classify 20 major insect pests by order, damage type, and the management tactic that acts as the first line of defense.

  • Outline horticultural propagation methods (seed, cutting, grafting, layering) and state one crop example for each.

  • Answer 50 mixed Domain 1 items under timed conditions and tag each error by sub-discipline.

Your checkpoint

A pest and disease identification table of 30 rows with symptom, causal agent, and control measure columns.

Week 3

Animal and Veterinary Sciences (animal breeding and genetics, animal nutrition, veterinary pathology, veterinary microbiology) & Soil Science and Agricultural Chemistry (soil fertility, soil physics, soil microbiology, environmental chemistry)

  • Explain the breed evaluation concepts of selection response, heritability, and breeding value, and work through three numeric problems.

  • Compute a balanced ration for one ruminant and one monogastric animal using feed composition tables, showing all steps.

  • Describe the key lesions and diagnostic approach in four common veterinary pathology conditions and the culture-based identification of three veterinary pathogens.

  • Relate soil texture, structure, and bulk density to water-holding capacity, and solve five soil physics calculations.

  • Distinguish the roles of Rhizobium, mycorrhizae, and free-living nitrogen fixers in soil fertility, and define the key soil fertility indices.

Your checkpoint

A worked ration formulation sheet plus a one-page soil physics and microbiology summary with all calculations shown.

Week 4

Soil Science and Agricultural Chemistry (soil fertility, soil physics, soil microbiology, environmental chemistry) & Agricultural Engineering (farm machinery and power, irrigation and drainage, soil and water conservation, food process engineering)

  • Explain soil reaction, cation exchange capacity, and buffering, and interpret a soil test report nutrient by nutrient.

  • Calculate fertilizer doses for a specified crop and soil test level, including split application scheduling.

  • Compare tillage, sowing, and harvesting machinery by function, power requirement, and field capacity, and solve three machinery selection problems.

  • Compute irrigation water requirement, application efficiency, and drainage coefficient for a sample field.

  • Describe soil erosion types and the principles of contour bunding, terracing, and check dams.

Your checkpoint

A full fertilizer recommendation and irrigation scheduling worksheet for one crop, with every formula and unit stated.

Week 5

Agricultural Economics, Extension and Statistics (farm management, agricultural marketing, extension education, biostatistics) & Food Science and Technology (food chemistry, food microbiology, food processing, dairy and meat technology)

  • Compute farm profitability measures (gross margin, net return, benefit-cost ratio) and break-even output from a given cost structure.

  • Explain agricultural marketing functions, price spread, and market efficiency, and calculate a price spread from a supply chain example.

  • Distinguish the principles of extension teaching methods and the stages of the adoption-diffusion process.

  • Select the correct statistical test (t, chi-square, ANOVA, correlation) for eight described research situations and interpret the p-value.

  • Summarize the principles of food preservation, the causes of food spoilage, and the parameters of thermal processing.

Your checkpoint

A farm budget and price spread case analysis of 2 pages plus a decision table matching eight scenarios to the correct statistical test.

Week 6

Food Science and Technology (food chemistry, food microbiology, food processing, dairy and meat technology) & Fisheries and Aquaculture (fish biology, aquaculture, fish nutrition, fish pathology)

  • Explain the compositional and processing differences among milk, meat, and cereal products, and the unit operations in each processing chain.

  • Describe the microorganisms of concern in food safety, their growth conditions, and the control measures used at each hurdle.

  • Outline fish biology essentials: respiration, osmoregulation, and reproduction, and relate them to pond management decisions.

  • Compare carp polyculture, composite fish culture, and intensive aquaculture systems by stocking density, species mix, and feed strategy.

  • Identify the signs, causative agents, and prophylaxis of five major fish diseases, and explain the formulation of a practical fish feed.

Your checkpoint

A comparative 2-page table of food processing unit operations and aquaculture systems, each row with a key parameter and a management implication.

Week 7

Environmental Science and Agroforestry (ecology, environmental pollution, natural resource management, agroforestry systems) & General Agricultural Awareness, Research Aptitude and Reasoning

  • Explain energy flow, nutrient cycling, and biodiversity concepts, and apply them to the design of an agroforestry system.

  • Classify major pollutants by source and effect, and describe two remediation or mitigation approaches for soil and water contamination.

  • Compare agroforestry systems (agrisilviculture, silvopasture, alley cropping) by component interaction and suitable agro-climatic zone.

  • Revise current agricultural schemes, institutions, and policy developments, and record the key facts in a dated note.

  • Practice 30 reasoning and research-aptitude items (data interpretation, logical deduction, research design) and record the timing per item.

Your checkpoint

A dated one-page current-affairs brief on agricultural schemes plus a timed reasoning practice score sheet.

Week 8

Plant Sciences (agronomy, genetics and plant breeding, plant pathology, entomology, horticulture, plant physiology) & General Agricultural Awareness, Research Aptitude and Reasoning

  • Take two full-length mock tests under exam timing, and analyze each by domain to find the weakest three areas.

  • Re-drill every logged error from weeks 1 to 7, and confirm that each concept is now explained correctly in your own words.

  • Condense all domain cheat sheets into a single 10-page final revision booklet ordered by exam weight.
