Growing one crop alone or in pure stand, either as a single crop or as a sequence of single crops within the year is called a Sole Cropping system. source: term wiki; Polycropping or Multiple Cropping. The practice of growing more than one (usually 2 or 3) variety of crops on the same land within a year is called Polycropping or Multiple Cropping. l Double-cropping (also known as sequential cropping) is the practice of planting a second crop immediately following the harvest of a first crop, thus harvesting two crops from the same field in one year. This is a case of multiple cropping, which requires a season long enough and crops that mature quickly enough to allow two harvests in one year.

Multiple Cropping in Tropical Asia R. R. Harwood and E. C. Price' Present and potential multiple cropping patterns are determined by a wide range of physical and socio-economic conditions against a background of available technology. We have therefore chosen to present multiple crop­. Functional biodiversity and cropping systems: The first chapter introduces the reader to plant competition in multiple cropping systems. The second chapter provides insights regarding the ecological role of biodiversity for crop protection from pest .

  The multiple cropping practice is essential to agriculture because it has been shown to significantly increase the grain yield and promote agricultural economic development. In this study, potential multiple cropping systems in China are calculated based on meteorological observation data by using the Agricultural Ecology Zone (AEZ) model. Following this, the changes in the potential cropping.   Cropping pattern in India. Cropping pattern is a dynamic concept because it changes over space and time. It can be defined as the proportion of area under various crops at a point of time.

Multiple cropping is a form of Ecological Intensification that is potentially highly sustainable when two or more crops are grown at the same time or in a sequence.

[1] It does this by balancing three key ecological processes: competition, on the one hand, and commensalism (one plant gaining benefits from the other) or mutualism (both plants benefitting each other) on the other. [2]. Summary. The load-displacement characteristics and the billet quality are studied in double cropping under a wide range of process conditions.

In particular, the effects of the following parameters are examined: i) work materials, ii) bar face orientations, iii) bar width-to-depth ratios, iv) presence of notchings, and v) cross-sectional by: 1.

multiple cropping systems in agriculture in the United States is presented. Research needs to be directed to test these alternatives. Multiple cropping is not a new form of agri-cultural technology, but instead is an ancient means of intensive farming.

Multiple cropping has been practiced in many parts of. Cassava is a long duration crop and varieties grown in the region take 12–18 months to maturity and these are commonly grown as monocropping and multiple cropping systems in Angola, Malawi, Mozambique, Zambia, and Zimbabwe.

The crop stays on the field three to four times longer than cereals such as maize, rice, and sorghum. Specifically, multiple cropping would result in a different water footprint since double-cropping systems generate more evapotranspiration than single-cropping systems to moderate the reduction of regional water cycle (Spera et al., ).

Meanwhile, multiple cropping would also modify the carbon footprint and nitrogen by: 3. The first cluster (“Service crops”) includes five case studies, which focus mainly on multiple cropping diversification strategies, focusing on fodder crops, cover crops or short term leys, and/or on strategies to break up maize monoculture in order to preserve soil and water resources.

p>Multiple cropping is an agriculture system long adopted by marginalized small holder farmers especially in hills and mountains. This practice was a meant to enhance farm productivity when.

Types of multiple cropping system 1) Sequential cropping 2) Inter cropping 3) Multi storied cropping 5. Sequential Cropping • Growing two or more crops in sequence on the same field per year.

The succeeding crop is planted after the preceding one has been harvested. • Crop intensification is only in the time dimension. The multiple cropping practice is essential to agriculture because it has been shown to significantly increase the grain yield and promote agricultural economic development.

In this study, potential multiple cropping systems in China are calculated based on meteorological observation data by using the Agricultural Ecology Zone (AEZ) model. Books at Amazon. The Books homepage helps you explore Earth's Biggest Bookstore without ever leaving the comfort of your couch.

The potential multiple cropping index (PMCI) is directly determined by the light-temperature-water condition. Figure 1 shows the technolog-ical framework designed for the calculation of the multiple cropping systems. Multiple cropping.

Multi- Cropping. A recent study conducted by the Centre for Economic and Social Studies (CESS) has highlighted the importance of multi-cropping system.

In multi cropping system, farmers grow two or more crops on farmland in one calendar year (unlike mono-cropping, that involves planting only one crop on a field).It includes inter-cropping, mixed-cropping and relay cropping. intercropping, relay cropping, sequential cropping, ratoon cropping, etc.

All such systems come under the general term multiple cropping. Need for intensive cropping • Cropping systems has to be evolved based on climate, soil and water availability for efficient use of available natural resources. Get this from a library. Multiple cropping and tropical farming systems.

[Willem C Beets] -- This book covers the uses of tropical farming systems in tropics of mixed, strip, relay, sequential and multistorey cropping. It discusses the aspects of the tropical farming systems including their. Multiple cropping allows for crop intensification in two dimensions, vertical and horizontal.

In multiple cropping, it is necessary to study pests over the entire cropping period, because the pests of one crop might be influenced by the previous crop as well as by companion crops in intercropping patterns.

The Cropping System D&E Spec Sheet is designed for describing and evaluating a single cropping system. Therefore, multiple D&E Spec Sheets will be needed in a Conservation Plan that involves multiple cropping systems. For example, if three different crop rotations are planned for use on the farm, then at least thre e separate D&E Spec Sheets.

Cropping rotation typically used in the Great Plains region because conditions are too dry for uninterrupted annual cropping [Winter Wheat]- [Grain Sorghum]- Fallow (3 year rotation) - Fallowing helps reserve soil moisture and provides weed control to maximize yield of the wheat crop.

Double cropping: This is a form of multiple cropping in which two crops are grown in sequence or interplanted on the same land in a month period (a year).of four corn-based crop sequences (CC, C–SB, C–OCL– C ropping systems perform multiple functions in SG–SB, and C–SB–SG–OCL) each at three N fertiliza-their role as agroecosystems.
