On-farm production of protein is limited in most dairy farm operations in arid and semi-arid environments. Cereal-legume intercropping could be a viable option to obtain forage with higher protein content. A two-year experiment was conducted during 2009 and 2010 growing seasons in a loamy soil to determine whether intercropping pattern of barley (Hordeum vulgare L.) and annual medic (Medica...
Abstract The economic and environmental performances of agriculture intercropping depend on the complementarities between crops that make up system. objective this work was to analyze citrus-based systems in Coastal Tablelands region Northeastern Brazil, aiming identify associations with better performances. study started construction a set integrated indicators, which field information recorde...
ارزیابی عملکرد اقتصادی و کارایی مصرف نور در کشت مخلوط و خالص ذرت و پنبه تحت تاثیر سطوح مختلف نیتروژن
In order to study the potential of maize-cotton intercropping for improving radiation use efficiency (RUE), an experiment was conducted as a factorial arrangement based on completely randomized block design with three replications at experimental filed of Ferdowsi University of Mashhad. The experimental treatments were nitrogen in four levels (0, 50, 100 and 150 Kg N ha-1) and planting pattern ...
Intercropping that involves coffee (Coffee arabica L.) and macadamia (Macadamia integrifolia Maiden & Betche) can achieve the complementarity between component crops aiming at better use of natural resources, hence resulting in optimum crop production. However, there is no detailed information scientific literature about biological economic efficiency coffee–macadamia intercropping. In this wor...
Nitrogen (N) transfer is well documented in legume-cereal intercropping but this is less often reported for legume-Brassica intercrops even though Brassica crops require higher levels of N fertilizers. The present study was carried out to quantify N transfer from legumes (Lupinus albus L., Trifolium incarnatum L. or Vicia sativa L.) to rapeseed (Brassica napus L.) using the split-root (15)N-lab...
Intensively-managed pine (Pinus spp.) have been shown to support diverse vertebrate communities, but their ability to support invertebrate communities, such as wild bees, has not been well-studied. Recently, researchers have examined intercropping switchgrass (Panicum virgatum), a native perennial, within intensively managed loblolly pine (P. taeda) plantations as a potential source for cellulo...
Aphids cause significant damage to crop plants. Studies regarding predator-prey relationships in fennel (Foeniculum vulgare Mill.) and cotton (Gossypium hirsutum L.) crops are important for understanding essential ecological interactions in the context of intercropping and for establishing pest management programs for aphids. This study evaluated the association among Hyadaphis foeniculi (Passe...
Field experiment was conducted at Central Institute of Medicinal and Aromatic Plants (CIMAP), Lucknow to evaluate the growth and yield of geranium and garlic in intercropping system. Maximum dry matter accumulation was noticed during 120-135 DAP. Dry matter accumulation in geranium paired sole was almost equal to geranium paired intercrop. Application of phosphorus at 40 kg P2 O5 ha -1 and 30 k...
Cropping patterns are defined as the sequence and spatial arrangement of annual crops on a piece land. Knowledge cropping is crucial for crop production land-use intensity. While related to land use intensity, they rarely reported in agricultural statistics, especially those relating small farms developing countries. Remote sensing has enabled mapping by monitoring crops’ temporal dynamics. In ...
in order to study the competition ability of amaranth and mungbean in fodder intercropping system under different crop residue management, a field experiment was conducted at two seasons (first planting of wheat and then intercropping management) in agricultural faculty of shahid chamran university of ahvaz during growing season of 2010-2011. the experimental design was split plot based on rand...
