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.
