What are the components of integrated farming systems and site-specific development for different agro-climatic zones?

Components include crop diversification, animal integration, agroforestry, and nutrient recycling. Site-specific development tailors practices to local climate, soil, water, and socio-economic conditions.

Explain methods of seed testing and steps of seed production in cross-pollinated crops.

Seed testing includes viability and germination tests, purity analysis, and moisture content. Seed production steps involve isolation, controlled pollination, harvesting at maturity, cleaning, and certification.

Elaborate the applications of GIS and GPS in agriculture.

GIS/GPS enable precision farming, soil mapping, yield prediction, site-specific irrigation, and resource management by geospatially mapping fields and crop performance.

Explain the economic importance and climate/soil requirements of major fodder and forage crops.

Fodder crops support livestock productivity; their suitability depends on soil texture, rainfall, and temperature ranges suitable for growth and nutrient value.

Describe irrigation water quality requirements and management for major field crops in Haryana.

Water quality must meet salinity, sodicity, and EC targets suitable for crops; management includes proper irrigation scheduling, drainage, and monitoring indicators of soil fertility and productivity.

Distinguish between integrated nutrient management and site-specific nutrient management; discuss factors influencing nutrient management.

Integrated nutrient management combines inorganic and organic sources; site-specific management targets nutrient needs based on soil tests. Influencing factors include soil fertility status, climate, crop type, and management practices.

What are the kinds of drought and their management with contingency crop planning?

Drought types include meteorological, agricultural, and hydrological droughts; management involves drought-resistant varieties, efficient irrigation, and contingency cropping plans.

Explain water use efficiency (WUE) to grow healthy crops and discuss strategies to improve WUE.

WUE is the crop yield per unit water used. Strategies include improved irrigation scheduling, mulching, soil moisture retention, and drought-tolerant varieties.

Describe the organization setup of agricultural research and extension and explain biological nitrogen fixation in crops.

Organizational setup includes research institutes and extension services. Biological nitrogen fixation involves symbiotic bacteria (e.g., Rhizobium) in legume roots fixing atmospheric N₂ into plant-available forms.

Explain distributed models for integrated business and factors influencing seed production in cross-pollinated crops.

Integrated business models distribute value chain roles for seed production; factors include genetics, breeding practices, pollination biology, and market demand.

Frequently asked questions

What is the difference between saline and sodic soils?

Saline soils have high soluble salts leading to high electrical conductivity, while sodic soils have high exchangeable sodium causing dispersion and poor soil structure. Remediation includes leaching salts, reducing structure-damaging sodium, adding amendments like gypsum, and using appropriate irrigation practices.

What are the roles of N, P, and K in crop plants and their deficiency symptoms in maize?

Nitrogen boosts vegetative growth and leaf area; phosphorus supports root development and energy transfer; potassium regulates water relations and enzyme activation. Deficiency symptoms include pale green to yellow leaves for N, stunted growth and purplish stems for P, and marginal leaf scorch and brittle tissues for K.

What are the Mendelian laws and why are they important for selecting traits in garden pea?

Mendel described segregation and independent assortment, explaining how traits are inherited in discrete units (genes). This underpins selective breeding for distinct characteristics in crops like peas.

Which major pests and diseases affect cotton and how can they be controlled?

Key pests include bollworms and aphids; common diseases include boll rot. Control methods include crop rotation, resistant varieties, timely insecticide applications, and integrated pest management.

What is seed dormancy and what factors cause it in crops?

Seed dormancy is a state preventing germination despite favorable conditions. Causes include physiological dormancy, coat dormancy, and environmental factors such as temperature and light requirements.

Describe quality seed production technology for wheat and its agro-climatic zones in India.

Quality seed production includes breeder/end-user seed multiplication, certification, and quality control, with zone-specific adaptation to climatic conditions to ensure high-yielding, disease-free seed lots.
