Improvement in Food Resources Test - 7

Mycorrhiza is a symbiotic association of Fungi and roots of higher plant.
Fungi helps in increasing absorption of water and other nutrients and angiosperm plants provide foods to fungi.

The science of vegetable culture is called horticulture. Horticulture is the science and art of growing (plants) -fruits, vegetables, flowers, and any other cultivar. It also includes plant conservation, landscape restoration, soil management, landscape and garden design, construction, and maintenance, and arboriculture.Horticulturists apply their knowledge, skills, and technologies used to grow intensively produced plants for human food and non-food uses and for personal or social needs. Their work involves plant propogation  and cultivation with the aim of improving plant growth, yields, quality, nutritional value, and resistance to insects, diseases, and environmental stresses

Disease resistant varieties of plants can be obtained by breeding with their wild relatives which are generally resistant to disease.

(1) Symbiosis                           (C) Legume – Rhizobium association - Symbiotic relationships are a special type of interaction between species. Sometimes beneficial, sometimes harmful, these relationships are essential to many organisms and ecosystems, and they provide a balance that can only be achieved by working together. A relationship of mutual benefit or dependence.... any interdependent or mutually beneficial relationship between two persons 
(2) Cropping pattern                 (B) Intercropping-  Intercropping is a multiple cropping practice involving growing two or more crops in proximity. The most common goal of intercropping is to produce a greater yield on a given piece of land by making use of resources or ecological processes that would otherwise not be utilized by a single crop
(3) Primary nutrients                (D) NPK-  Micronutrients are essential for plant growth and play an important role in balanced crop nutrition. They include boron (B), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), zinc (Zn), nickel (Ni) and chloride (Cl).This study compared availability of boron (B), copper (Cu), manganese (Mn), and zinc (Zn) in the soil and their effect in developing maize plants, supplied from a physical mixture of nitrogen, phosphorus, and potassium (NPK) granules andmicronutrients or from a granulated mixture of NPK coated.
(4) Crop season                       (A) Rabi- Rabi crops or Rabi harvest are agricultural crops sown in winter and harvested in the spring in the South Asia. The term is derived from the Arabic word for "spring", which is used in the Indian subcontinent, where it is the spring harvest also known as the "winter crop"

(1) Eutrophication      (D) Kills aquatic organisms- Eutrophication arises from the oversupply of nutrients, which leads to overgrowth of plants and algae. After such organisms die, the bacterial degradation of their biomass consumes the oxygen in the water, thereby creating the state of hypoxia
(2) Crop rotation        (A) Increases fertility of soil- crop rotation mitigates the buildup of pathogens and pests that often occurs when one species is continuously cropped, and can also improve soilstructure and fertility by increasing biomass from varied root structures.
(3) Fumigants            (C) Vapourises and kills insects- Soil fumigation is a preplant chemical treatment of soil, using a pesticide product that converts to form a volatile gas. The gas is able to diffuse through open pore .  At low temperatures, thefumigant vaporizes and diffuses slower. 
(4) Hybridization        (B) Improves genetic makeup of crop plants-  The natural or artificial process that results in the formation of hybrid is known as hybridization. The production of a hybrid by crossing two individuals of unlike genetical constitution is known as hybridization. Hybridization is an important method of combining characters of different plants. Hybridization does not change genetic contents of organisms but it produces new combination of genes.

A weed is a plant considered undesirable in a particular situation, plant in the wrong place.Weeds threaten the survival of many plants as the weedscompete with native plants for space, nutrients and sunlight. Weeds compete with flowers, grasses, vegetable and fruit plants for water, sunlight and nutrients leaving non-weed plants starving. Because most weeds grow at such an astounding rate, they often absorb more of one nutrient than another, leaving an imbalance. competing with the desired plants for the resources that a plant typically needs, namely, direct sunlight, soil nutrients, water, and (to a lesser extent) space for growth; providing hosts and vectors for plant pathogens, giving them greater opportunity to infect and degrade the quality of the desired plants.

The Green Revolution in India was a period when agriculture in India increased due to improved method & technology.

Swaminathan is known as "Indian Father of Green Revolution" for his leadership and success in introducing and further developing high-yielding varieties of wheat in India. He is the founder and chairman of the MS Swaminathan Research Foundation.

A weed is a plant considered undesirable in a particular situation, a plant in the wrong place which compete for sunlight, soil ,nutrients, place with the main plant. Weed control is the botanical component  which attempts to stop weeds, especially injurious weeds, from competing with desired flora and fauna, this includes domesticated plants, and in natural settings, it includes stopping non local species competing with native, local, species, especially so in reserves and heritage areas.Weed control is important in agriculture Many strategies have been developed in order to contain these plants. Methods include hand cultivation with hoes, powered cultivation with cultivators, smothering with mulch, lethal wilting with high heat, burning, and chemical attack with herbicides.

The largest producer of milk in the world is India. The number of cattle in India is more than any other country but quantity of milk per cow is less in comparison to other countries.

Sahiwal is indigenous breed of cow. This breed of cow is superior to other dairy cows. The animal is large and of heavier built.
