Q1Foot and Mouth Disease (FMD) in livestock is caused by which type of pathogen?
Foot and Mouth Disease (FMD) is caused by an Aphthovirus belonging to the family Picornaviridae. It affects cloven-hoofed animals (cattle, buffalo, pigs, sheep, goats). India runs the FMD-CP (Control Programme) and FMD-PCP (Progressive Control Pathway) under the National Animal Disease Control Programme (NADCP) to achieve FMD-free status by 2030.
Q2Consider the following statements about sericulture in India: 1. India produces all the commercial varieties of silk mentioned by the Central Silk Board. 2. Mulberry, tasar, muga and eri are among the major silk types of commercial importance. 3. Eri silk is spun from open-ended cocoons and its silkworm mainly feeds on castor leaves. 4. Muga silk is obtained from the domesticated Bombyx mori silkworm that feeds solely on mulberry leaves. Which of the statements given above are correct?
Statements 1 and 2 are correct: the CSB page says India has the unique distinction of producing all commercial varieties and lists mulberry, tasar, muga and eri among the major types. Statement 3 is correct: the CSB Eri page describes open-ended cocoons and castor leaves. Statement 4 is incorrect because the cited CSB page identifies Bombyx mori and mulberry leaves with mulberry silk, not muga silk.
Q3Consider the following statements about biofortified crop varieties in India: 1. Biofortified maize hybrids may be enriched with lysine and tryptophan. 2. Some wheat biofortified varieties are enriched with protein and iron. 3. Pusa Mustard 32 is described as enriched with low erucic acid. 4. Biofortification necessarily introduces foreign-species DNA into every crop variety. Which of the statements given above are correct?
Statement 1 is correct: ICAR describes maize hybrids enriched with lysine and tryptophan. Statement 2 is correct: the cited ICAR page mentions wheat varieties enriched with protein and iron. Statement 3 is correct: Pusa Mustard 32 is described with low erucic acid. Statement 4 is incorrect: the ICAR bulletin says nutritional quality has been improved using breeding methods, so biofortification is not necessarily transgenic.
Q4Consider the following statements about sustainable agriculture and certification: 1. Climate-smart agriculture pursues the objectives of productivity, adaptation and greenhouse-gas mitigation where possible. 2. A Soil Health Card records soil status with respect to 12 parameters. 3. The National Programme for Organic Production is operated under the overall guidance of the Department of Agriculture and Farmers Welfare. 4. Zero Budget Natural Farming relies heavily on synthetic inputs to reduce cultivation cost. Which of the statements given above are correct?
Statements 1 and 2 are correct. FAO defines CSA around productivity, adaptation and possible greenhouse-gas reduction; the Soil Health Card lists 12 soil parameters. Statement 3 is incorrect because NPOP is under the Department of Commerce framework with APEDA as secretariat. Statement 4 is incorrect because ZBNF avoids synthetic inputs rather than relying on them.
Q5With reference to climate-smart agriculture technologies, which of the following is CORRECTLY matched? (Variety/Technology -- Feature)
Option A is correctly matched. The Sub1 (Submergence 1) gene, specifically the Sub1A allele discovered in FR13A rice landrace, confers tolerance to complete submergence for up to 17 days. IRRI and national programmes (including ICAR in India) have introgressed Sub1 into popular varieties like Swarna, Samba Mahsuri, and CR1009 Sub1. This is critical for flood-prone rice ecosystems in eastern India.

AI is a treatment for infertility or repeat breeding. 3. AI helps reduce the risk of disease transmission through natural service. Which of the statements given above are correct?
7Consider the following statements about cold chain technology and food processing in India: 1. Cold chain refers to an uninterrupted, temperature-controlled supply chain from farm gate to consumer, with commodity-specific temperatures across production, storage, transport and retail. 2. The Pradhan Mantri Kisan Sampada Yojana (PMKSY) provides financial assistance for integrated cold chain projects. 3. MAP (Modified Atmosphere Packaging) technology is used to extend shelf life by altering the composition of gases around the food product. 4. India has a surplus of cold storage capacity and does not face any post-harvest losses. Which of the above statements are correct?
8Consider the following statements about the Soil Health Card scheme: 1. The scheme was launched in 2015. 2. It tests soil for 12 parameters. 3. Cards are issued to farmers every 5 years. Which of the statements given above are correct?
9Consider the following statements about livestock diseases and vaccines: 1. Foot and Mouth Disease is caused by an Aphthovirus of the family Picornaviridae. 2. PPR vaccine is linked with Peste des Petits Ruminants, a morbillivirus disease affecting small ruminants. 3. HS vaccine is linked with Hemorrhagic Septicemia caused by Pasteurella multocida. 4. Brucella S-19 strain vaccine is used for Foot and Mouth Disease. Which of the statements given above are correct?
10Consider the following statements about micro-irrigation and fertigation: 1. Drip irrigation delivers water directly near the root zone and reduces evaporation losses. 2. Drip irrigation is generally less water-efficient than flood irrigation. 3. Fertigation applies fertilizers or other soluble products through an irrigation system. 4. Drip irrigation is useful only for cereal crops and not for orchard crops. Which of the statements given above are correct?
11Consider the following statements about biofertilizers and nitrogen fixation: 1. Root nodule development is a key event in legume plants for nitrogen fixation. 2. Mesorhizobium can form a symbiotic relationship with chickpea and help fix environmental nitrogen. 3. Rhizobium-type biofertilizers mainly act by killing all soil microbes around crop roots. 4. Symbiotic nitrogen fixation occurs only in cereal crops and not in legumes. Which of the statements given above are correct?
12Consider the following statements about climate-smart agriculture: 1. It aims to sustainably increase agricultural productivity and incomes. 2. It is a single fixed package of practices suitable for all local conditions. 3. It includes reducing or removing greenhouse gas emissions where possible. Which of the statements given above are correct?
13Consider the following statements about fertigation and micro-irrigation: 1. Fertigation means applying fertilizers or water-soluble products through an irrigation system. 2. It can be used with drip or sprinkler irrigation. 3. It is designed to deliver nutrients away from the root zone. 4. It generally reduces nutrient-use efficiency by increasing fertilizer wastage. Which of the statements given above are correct?
14Consider the following statements about the Anand Pattern in India's dairy sector: 1. It is a three-tier dairy cooperative model associated with Anand in Gujarat. 2. It includes village-level primary milk producer cooperatives, district-level milk unions and state-level federations. 3. It is a model based only on private dairy companies, without cooperatives. Which of the statements given above are correct?
15Consider the following statements about cold chain and food-processing technologies: 1. Cold chain refers to an uninterrupted, temperature-controlled supply chain from farm gate to consumer. 2. PMKSY has a component for integrated cold chain and value-addition infrastructure. 3. Modified Atmosphere Packaging extends shelf life by changing the gas composition around the food product. 4. UHT treatment of milk, under the cited standard, requires heating at at least 135 degrees Celsius for one minute or more. Which of the statements given above are correct?
