31 cards. Read the term and the definition here. The deck at the top of this page is optional.
- AIEEA (PG) total marks
- The paper carries 120 questions of 4 marks each, giving 480 marks in 120 minutes, with 1 mark deducted for every wrong answer and zero for unattempted questions.
- Negative marking expected value
- With 4 options, 4 marks for correct and 1 mark deducted for wrong, a random guess has expected value 4×0.25 minus 1×0.75, equal to +0.25 marks.
- PG eligibility percentage
- A bachelor's degree in the relevant field with at least 60% marks or equivalent OGPA is required, relaxed to 55% for SC, ST and PwD candidates.
- PG minimum pass marks
- Candidates must score at least 25% to qualify in the General and OBC categories, while SC, ST and PwD candidates need a minimum of 20%.
- PG paper composition
- The question paper has two parts: 60 subject-specific questions from the chosen discipline and 60 questions on aptitude, reasoning, numerical ability and general awareness.
- PG admission weightage
- For ICAR-Deemed Universities, the entrance test score and undergraduate academic performance are combined, commonly in a 70:30 ratio as specified in that year's bulletin.
- Subject-locked merit list
- Merit lists are prepared separately for each subject; a candidate is considered only for the discipline in which the entrance test was actually written.
- PG test language rule
- The test is offered in English and Hindi, the language chosen in the application is final, and the language printed on the question paper prevails in disputes.
- AICE-JRF/SRF paper pattern
- The doctoral stream test has 120 subject-specific questions at master's level in 120 minutes, worth 480 marks, with 4 marks awarded and 1 mark deducted.
- Ph.D. stream eligibility
- A master's degree in the concerned discipline with at least 60% marks or equivalent OGPA is required, relaxed to 55% for SC, ST and PwD candidates.
- JRF versus SRF
- JRF is for candidates not yet registered in a Ph.D., while SRF applies to those already registered or having completed at least two years of doctoral work.
- Ph.D. stream qualifying marks
- To enter the merit list, General and OBC candidates need 30% and SC, ST and PwD candidates need 25% of the total 480 marks.
- Fellowship needs admission
- Clearing AICE-JRF/SRF alone does not confer a fellowship; the candidate must also secure admission to a Ph.D. programme at an ICAR-recognised institution.
- No aptitude section in Ph.D. test
- Unlike the PG test, the doctoral entrance paper contains no general aptitude component; all 120 questions come from the master's-level subject syllabus.
- Online ICAR counselling
- Seat and fellowship allocation follows online counselling based on rank, category, state quota and availability; skipping counselling forfeits the claim for that year.
- Master's-level subject syllabus
- Doctoral questions follow ICAR's postgraduate syllabus for the chosen discipline, covering advanced theory, applied methods and recent developments in that field.
- Heterosis
- Heterosis is the superior performance of an F1 hybrid over its parents, measured as mid-parent or better-parent heterosis and exploited commercially in cross-pollinated and some self-pollinated crops.
- General combining ability
- General combining ability is the average performance of a line in crosses with a set of testers, reflecting additive gene action and estimated from line means in a line-by-tester design.
- Specific combining ability
- Specific combining ability is the deviation of a particular cross from the expectation based on parental general combining abilities, attributed mainly to non-additive dominance and epistatic effects.
- Line × tester analysis
- Line × tester analysis crosses several lines with a few testers to estimate general and specific combining ability and to identify promising parents and crosses for hybrid breeding.
- Coefficient of variation formula
- The coefficient of variation equals the standard deviation divided by the mean, usually expressed as a percentage, and allows comparison of variability across traits with different units.
- Critical difference
- Critical difference equals the standard error of a difference multiplied by the t-value at the chosen probability level, and it is the minimum gap needed to declare two treatment means significantly different.
- Law of minimum
- Liebig's law of the minimum states that yield is limited by the nutrient present in shortest supply relative to crop requirement, not by nutrients available in excess.
- Water use efficiency
- Water use efficiency is the ratio of economic yield or dry matter produced to the water consumed by the crop, often expressed in kilograms per hectare-millimetre.
- Koch's postulates
- Koch's postulates require that a pathogen be consistently isolated from diseased tissue, grown in pure culture, reproduce the disease on reinoculation, and be re-isolated from the new host.
- Economic threshold level
- The economic threshold level is the pest density at which control measures should be initiated to prevent the population from reaching the economic injury level.
- Heritability in broad sense
- Broad-sense heritability is the ratio of total genetic variance to phenotypic variance, indicating the proportion of phenotypic variation that is genetically determined in a population.
- Genotype × environment interaction
- Genotype × environment interaction occurs when genotypes respond differently across environments, making rankings change and requiring multi-location trials for reliable variety recommendation.
- Randomised block design
- A randomised block design divides the experimental area into homogeneous blocks containing every treatment once, controlling field variation in one direction and analysed with two-way ANOVA.
- Soil organic carbon
- Soil organic carbon is the carbon fraction of soil organic matter, commonly estimated as organic matter divided by 1.724, and it governs nutrient supply, structure and microbial activity.
- Technology adoption in extension
- Adoption is the decision to use an innovation continuously; it is measured by extent of use and influenced by relative advantage, compatibility, trialability, observability and complexity.
