The standard size of the Agrometeorology Observatory is -
120' x 100'
140' x 100'
160' x 120'
180' x 120'
✓
Correct Answer: 180' x 120' The standard dimensions recommended by the India Meteorological Department (IMD) for a Class B Agrometeorological Observatory site are typically around 180 feet by 120 feet (approximately 55m x 36m) to allow adequate space for various meteorological instruments.
Harmful solar radiation absorbed by the ozone layer in the earth's atmosphere is primarily:
Violet rays
Ultraviolet rays
Red rays
Infrared rays
✓
Correct Answer: Ultraviolet rays The ozone layer, located in the stratosphere, effectively absorbs most of the Sun's harmful ultraviolet (UV) radiation, particularly the high-energy UV-B and UV-C types, protecting life on Earth.
Which chemical is used as a defoliant to improve boll opening in cotton?
Thiadiazuron 100g/ha
NAA 30g/ha
Colchicine 10g/ha
TGA 50g/ha
✓
Correct Answer: Thiadiazuron 100g/ha Thiadiazuron (TDZ) is a plant growth regulator commonly applied to cotton before harvest. It acts as a defoliant (causing leaves to drop) and accelerates the opening of mature cotton bolls, facilitating mechanical harvesting.
'Madhuri' is an improved cultivar of which type of maize crop?
Quality Protein corn
Baby corn
Popcorn
Sweet corn
✓
Correct Answer: Sweet corn 'Madhuri' is a popular hybrid variety of sweet corn in India, specifically bred for its high sugar content and desirable taste for human consumption.
Crop logging is a method of :
Soil fertility evaluation
Planning nutrient requirements for yield maximization
Assessing crop damage
Testing the suitability of fertilizer
✓
Correct Answer: Planning nutrient requirements for yield maximization Crop logging involves regular monitoring and analysis of specific plant parts (like leaves) during the growing season to assess the crop's nutrient status. This information guides fertilizer application decisions to optimize nutrient supply for maximizing yield.
Major constituent of sunn hemp fiber, which makes it a suitable indigenous raw material for currency paper, is:
Cellulose
Pentosan
Lignin
Urinic anhydrite
✓
Correct Answer: Cellulose Sunn hemp (Crotalaria juncea) fiber is predominantly composed of cellulose, which provides the necessary strength, flexibility, and durability required for producing high-quality paper, including currency notes. Its relatively low lignin content is also advantageous.
The accumulation of temperature above a minimum threshold required for crop growth, calculated from mean daily temperature, is termed as:
Diurnal variation
Heat Unit
Temperature gradient
Lapse rate
✓
Correct Answer: Heat Unit A Heat Unit, also known as a Growing Degree Day (GDD), measures the amount of heat available for plant growth. It's calculated as the difference between the average daily temperature and a crop-specific base (minimum threshold) temperature, accumulated over time.
The total water resources available through annual precipitation in India are estimated to be:
5320 Billion cubic meter (BCM)
4000 BCM
1800 BCM
1700 BCM
✓
Correct Answer: 4000 BCM India receives an average annual precipitation that equates to approximately 4000 Billion Cubic Meters (BCM) of water. This is the total volume falling as rain or snow across the country annually.
The individual crop has its minimum, optimum, and maximum temperature limits for growth and development called as:
Temperature gradient
Required temperatures
Cardinal temperatures
Diurnal variation in temperatures
✓
Correct Answer: Cardinal temperatures Cardinal temperatures define the critical temperature range for a plant's physiological processes: the minimum below which growth stops, the optimum at which growth is maximal, and the maximum above which growth ceases and injury may occur.
The simultaneous use of two sources of water, namely surface and underground water, to irrigate a piece of land is called as-
Consumptive use of water
Seasonal consumptive use of water
Conjunctive use of water
Total crop water requirement
✓
Correct Answer: Conjunctive use of water Conjunctive use of water involves the coordinated and integrated use of both surface water (like canals, rivers) and groundwater (from wells or tube wells) to meet irrigation demands more efficiently and sustainably.
Amongst cereals, the grains of which crop possess the highest fat content?
Pearl millet
Sorghum
Wheat
Barley
✓
Correct Answer: Pearl millet Pearl millet (Bajra) generally contains a higher percentage of fat (lipids), typically around 5-7%, compared to other common cereals like sorghum (~3-4%), wheat (~1.5-2.5%), and barley (~1.5-2.5%).
Name a multi-cut cultivar of forage sorghum.
Pusa chari 6
Rajasthan Chari 2
SSG 59-3
HC 308
✓
Correct Answer: SSG 59-3 SSG 59-3 is a well-known hybrid variety of forage sorghum specifically developed for its multi-cut characteristic, meaning it can regrow after harvesting, allowing for multiple cuttings of fodder from a single planting.
Mustard oil cake is unpalatable due to the presence of
Sinigrin
Carotenoids
Selenium
Magnesium
✓
Correct Answer: Sinigrin Mustard oil cake contains glucosinolates, predominantly sinigrin. When broken down by enzymes, sinigrin produces pungent isothiocyanates which impart a bitter taste, making the cake unpalatable and potentially toxic to livestock if not processed properly.
Indian Institute of Spices Research is situated at -
Ajmer
Anand
Calicut
New Delhi
✓
Correct Answer: Calicut The Indian Institute of Spices Research (IISR), operating under the Indian Council of Agricultural Research (ICAR), has its main campus located in Kozhikode (formerly known as Calicut) in the state of Kerala.
Which variety of sesame possesses Quadricarpellate capsules?
RT 46
RT 125
RT 346
RT 351
✓
Correct Answer: RT 351 RT 351 is a specific variety of sesame ( Sesamum indicum) that is known to exhibit the trait of quadricarpellate capsules, meaning its seed pods have four chambers instead of the usual two, potentially influencing seed yield.
