Agroforestry Introduction for B.Sc. Agriculture

० The oldest known agroforestry system is shifting cultivation.

० Basic set of elements or components of agroforestry are tree, crops, animals.

० Silvi-agriculture refers to growing trees along with agricultural crops.

० Tree planted in silvi-agriculture should be oriented in the East West direction.

० “The Journal of Agroforestry Today” is published from Kenya.

० Indian Grassland and Fodder Research Institute is located at Jhansi.

० The ratio of height and spacing in a shelterbelt is 1 : 10.

० Hedgerow intercropping is otherwise called as alley cropping.

० Rotation of aerable crops with two or more years of sown pasture is called as lay farming.

० In north eastern hill region, shifting cultivation is called as Jhum.

० Most common agroforestry system practiced in arid regions are Agrisilvicultural Systems.

० Based on temporal arrangement of agroforestry system, “home garden” is the example of interpolated.

० Tree planted in silvi-agriculture should be oriented in the East West direction.

० Nitrogen fixing non-leguminous tree Casuarina.

० Protection forestry practice is not included in the scope of social forestry.

० Farm forestry programmes is purely managed by private efforts.

० A major cause of soil erosion is deforestation.

० An agroforestry system always has two or more outputs.

० The cycle of an agroforestry system is always more than one year.

० Normally an agroforestry system is more complex ecologically and economically than a monocropping system.

० The International Institute of Tropical Agriculture is established at Ibadan (Nigeria).

० The Indian Grassland and Fodder Research Institute is located at Jhansi.

० Central Soil and Water Conservation Research and Training Institute is at Dehradun.

० India has been classified into 8 agroecological regions.

० The shifting cultivation is called “Podu” in the Andhra Pradesh and Odissa.

० Taungya is a Burmese word.

० Taungya system was introduced into India by Brandis.

० Taungya is a modified form of shifting cultivation.

० Home garden is a subsystem of agrosilvopasture.

० Home garden is highly suitable for humid/sub humid region.

० Generally shelter belt assumes the shape of triangle.

० Energy plantation is established for fuel wood production.

० Waste land is the land with < 20 % productivity.

० K.M. Munshi initiated Van Mahostava.

० Vanamahostava was started in 1950.

० The first state to create separate Social Forestry wing was Maharastra.

० A silvopastoral system is widely practiced in dry areas.

० The home garden is widely practiced in high rainfall areas.

० Primary function of most of the home garden is food production.

० The characteristic of home gardens is high species diversity.

० The freshly cut wood contains about 23 – 25 % of moisture content.

० Benefit sharing concept is a core objective in Joint Forest Management (JFM).

० The major species used for planting on tank bed is Acacia nilotica.

० Heliotropic type of branching should be preferred for roadside planting.

० In Social Forestry, the peoples representative body is called as Village Forest Council (VFC).

० Allelopathy is the best example for Amensalism.

० The competition is also referred as allelospoly.

० The unit of management under JFM is a village.

० TCIP stands for “Tree Cultivation Incentive Programme”.

० JFMC stands for “Joint Forest Management Committee”.

० FDA stands for “Forest Development Agency”.

० NAP stands for “National Afforestation Programme”.

० The taungya is a Burmese word coined in Burma in 1850.

० The production of woody perennial combined with annuals and pastures is known as agrisilvopastural system.

० Home garden is practiced extensively in the state of Kerala and Tamil Nadu.

० Home garden can also be called as multi-tier system.

० The primary function of home garden is food production.

० Various trees and shrubs preferred by fish are planted on the boundry and around fish ponds are called as aqua forestry.

० The broad and well known classification of agroforestry systems was given by Nair.

० A common example of the zonal pattern of agroforestry is home gardens.

० Integration of various farm enterprises in farming system is called as Integrated Farming System (IFS).

० Phytoplankton and Zooplankton are major food for fishes.

० The main host plant of silk worm is mulberry.

० The hydrological unit that drains at a common point is called watershed.

० The drainage area of catchments is more than one lakh ha.

० The continuous circulation of water among the hydrosphere, atmosphere and lithosphere is called as hydrological cycle.

० The drainage area of sub watershed is 2000 – 4000 ha.

० The drainage area of a mini watershed is 400 – 2000 ha.

० The drainage area of a micro watershed is < 400 ha.

० The process of taking up nutrients from deeper soil profiles and depositing them on the surface layer is referred to nutrient pumping.

० NWDB classified wastelands into 2 types.

० Tree selected for Agroforestry should have deep root system, nitrogen fixing and leaf fall in winter.

० The main criteria for good Agroforestry desing are productivity, sustainability and adoptability.
