In 2003 and 2004, 534 trees were planted, representing 64 different cultivars, varieties, and species. Twenty trees from each of 20 different cultivars were planted as five-tree plots in a randomized complete block design in four blocks of 100 trees each, amounting to 400 trees. The remaining 44 chestnut cultivars, varieties, and species served as a germplasm collection. These were planted in guard rows surrounding the four blocks in completely randomized, single-tree plots. In the analysis, we investigated our collection predominantly with the aim to: 1) discover the degree of acclimation of grower- recommended cultivars to southeastern Tennessee climatic conditions and 2) ascertain the cultivars’ ability to survive in the area with Cryphonectria parasitica and other chestnut diseases and pests present.

  • Nutritive Value and Degradability of Leaves from Temperate Woody Resources for Feeding Ruminants in Summer
    3rd European Agroforestry Conference Montpellier, 23-25 May 2016 Silvopastoralism (poster) NUTRITIVE VALUE AND DEGRADABILITY OF LEAVES FROM TEMPERATE WOODY RESOURCES FOR FEEDING RUMINANTS IN SUMMER Emile JC 1*, Delagarde R 2, Barre P 3, Novak S 1 Corresponding author: [email protected] mailto:(1) INRA, UE 1373 FERLUS, 86600 Lusignan, France (2) INRA, UMR 1348 INRA-Agrocampus Ouest, 35590 Saint-Gilles, France (3) INRA, UR 4 URP3F, 86600 Lusignan, France 1/ Introduction Integrating agroforestry in livestock farming systems may be a real opportunity in the current climatic, social and economic conditions. Trees can contribute to improve welfare of grazing ruminants. The production of leaves from woody plants may also constitute a forage resource for livestock (Papanastasis et al. 2008) during periods of low grasslands production (summer and autumn). To know the potential of leaves from woody plants to be fed by ruminants, including dairy females, the nutritive value of these new forages has to be evaluated. References on nutritive values that already exist for woody plants come mainly from tropical or Mediterranean climatic conditions (http://www.feedipedia.org/) and very few data are currently available for the temperate regions. In the frame of a long term mixed crop-dairy system experiment integrating agroforestry (Novak et al. 2016), a large evaluation of leaves from woody resources has been initiated. The objective of this evaluation is to characterise leaves of woody forage resources potentially available for ruminants (hedgerows, coppices, shrubs, pollarded trees), either directly by browsing or fed after cutting. This paper presents the evaluation of a first set of 12 woody resources for which the feeding value is evaluated through their protein and fibre concentrations, in vitro digestibility (enzymatic method) and effective ruminal degradability.

  • The Conversion of Abandoned Chestnut Forests to Managed Ones Does Not Affect the Soil Chemical Properties and Improves the Soil Microbial Biomass Activity
    Article The Conversion of Abandoned Chestnut Forests to Managed Ones Does Not Affect the Soil Chemical Properties and Improves the Soil Microbial Biomass Activity Mauro De Feudis 1,* , Gloria Falsone 1, Gilmo Vianello 2 and Livia Vittori Antisari 1 1 Department of Agricultural and Food Sciences, Alma Mater Studiorum—University of Bologna, Via Fanin, 40, 40127 Bologna, Italy; [email protected] (G.F.); [email protected] (L.V.A.) 2 Centro Sperimentale per lo Studio e l’Analisi del Suolo (CSSAS), Alma Mater Studiorum—University of Bologna, 40127 Bologna, Italy; [email protected] * Correspondence: [email protected] Received: 20 June 2020; Accepted: 19 July 2020; Published: 22 July 2020 Abstract: Recently, several hectares of abandoned chestnut forests (ACF) were recovered into chestnut stands for nut or timber production; however, the effects of such practice on soil mineral horizon properties are unknown. This work aimed to (1) identify the better chestnut forest management to maintain or to improve the soil properties during the ACF recovery, and (2) give an insight into the effect of unmanaged to managed forest conversion on soil properties, taking in consideration sweet chestnut (Castanea sativa Mill.) forest ecosystems. The investigation was conducted in an experimental chestnut (Castanea sativa Mill.) forest located in the northern part of the Apennine chain (Italy). We identified an ACF, a chestnut forest for wood production (WCF), and chestnut forests 1 for nut production with a tree density of 98 and 120 plants ha− (NCFL and NCFH, respectively). WCF, NCFL and NCFH stands are the result of the ACF recovery carried out in 2004.

  • Nut Production, Marketing Handout
    Nut Production, Marketing Handout Why grow nuts in Iowa??? Nuts can produce the equivalent of a white-collar salary from a part-time job. They are up to 12 times more profitable per acre than corn was, even back when corn was $8/bushel. Nuts can accomplish the above with just a fraction of the investment in capital, land, and labor. Nuts can be grown in a biologically diverse perennial polyculture system with the following benefits: Builds soil instead of losing it to erosion Little or no chemical inputs needed Sequesters CO2 and builds soil organic matter Increases precipitation infiltration and storage, reduces runoff, building resilience against drought Produces high-quality habitat for wildlife, pollinating insects, and beneficial soil microbes Can build rural communities by providing a good living and a high quality of life for a whole farm family, on a relatively few acres If it’s so great, why doesn’t everybody do it? “Time Preference” economic principle: the tendency of people to prefer a smaller reward immediately over having to wait for a larger reward. Example: if an average person was to be given the choice between the following…. # 1. $10,000 cash right now, tax-free, no strings, or #2. Work part-time for 10 years with no pay, but after 10 years receive $100,000 per year, every year, for the rest of his/her life, and then for his/her heirs, in perpetuity… Most would choose #1, the immediate, smaller payoff. This is a near-perfect analogy for nut growing. Nut growing requires a substantial up-front investment with no return for the first five years, break-even not until eight to ten years, then up to $10,000 per acre or more at maturity, 12-15 years.

  • Brewing Beer with Native Plants (Seasonality)
    BREWING BEER WITH INDIANA NATIVE PLANTS Proper plant identification is important. Many edible native plants have poisonous look-alikes! Availability/When to Harvest Spring. Summer. Fall Winter . Year-round . (note: some plants have more than one part that is edible, and depending on what is being harvested may determine when that harvesting period is) TREES The wood of many native trees (especially oak) can be used to age beer on, whether it be barrels or cuttings. Woods can also be used to smoke the beers/malts as well. Eastern Hemlock (Tsuga Canadensis): Needles and young twigs can be brewed into a tea or added as ingredients in cooking, similar flavoring to spruce. Tamarack (Larix laricina): Bark and twigs can be brewed into a tea with a green, earthy flavor. Pine species (Pinus strobus, Pinus banksiana, Pinus virginiana): all pine species have needles that can be made into tea, all similar flavor. Eastern Red Cedar (Juniperus virginiana): mature, dark blue berries and young twigs may be made into tea or cooked with, similar in flavor to most other evergreen species. Pawpaw (Asimina triloba): edible fruit, often described as a mango/banana flavor hybrid. Sassafras (Sassafras albidum): root used to make tea, formerly used to make rootbeer. Similarly flavored, but much more earthy and bitter. Leaves have a spicier, lemony taste and young leaves are sometimes used in salads. Leaves are also dried and included in file powder, common in Cajun and Creole cooking. Northern Hackberry (Celtis occidentalis): Ripe, purple-brown fruits are edible and sweet. Red Mulberry (Morus rubra): mature red-purple-black fruit is sweet and juicy.

A major consequence of this 2 3 phenomenon is the re-colonization of these areas by the original vegetation. However, some 4 agricultural, exotic species are able to naturalize and colonize these abandoned lands. In this 5 6 study we explore the ability of almonds (Prunus dulcis D.A. Webb.) to establish in abandoned 7 croplands in semi-arid areas of SE Iberian Peninsula. Domesticated during the early Holocene 8 9 in SW Asia and the Eastern Mediterranean, the almond has spread as a crop all over the world. 10 We established three plots adjacent to almond orchards on land that was abandoned and 11 12 reforested with Aleppo pine (Pinus halepensis Mill.) and Holm oak (Quercus ilex L.) about 20 13 years ago.

  • Localized Gene Expression Changes During Adventitious Root Formation in Black Walnut (Juglans Nigra L.)
    Tree Physiology 38, 877–894 doi:10.1093/treephys/tpx175 Research paper Localized gene expression changes during adventitious root formation in black walnut (Juglans nigra L.) Micah E. Stevens1, Keith E. Woeste2 and Paula M. Pijut2,3 1Department of Forestry and Natural Resources, Purdue University, Hardwood Tree Improvement and Regeneration Center (HTIRC), 715 West State Street, West Lafayette, IN 47907, USA; 2USDA Forest Service, Northern Research Station, HTIRC, 715 West State Street, West Lafayette, IN 47907, USA; 3Corresponding author ([email protected]) Received May 31, 2017; accepted December 20, 2017; published online January 25, 2018; handling Editor Danielle Way Cutting propagation plays a large role in the forestry and horticulture industries where superior genotypes need to be clonally multiplied. Integral to this process is the ability of cuttings to form adventitious roots. Recalcitrance to adventitious root develop- ment is a serious hurdle for many woody plant propagation systems including black walnut (Juglans nigra L.), an economically valuable species. The inability of black walnut to reliably form adventitious roots limits propagation of superior genotypes. Adventitious roots originate from different locations, and root induction is controlled by many environmental and endogenous factors. At the molecular level, however, the regulation of adventitious root formation is still poorly understood. In order to eluci- date the transcriptional changes during adventitious root development in black walnut, we used quantitative real-time polymer- ase chain reaction to measure the expression of nine key genes regulating root formation in other species. Using our previously developed spatially explicit timeline of adventitious root development in black walnut softwood cuttings, we optimized a laser capture microdissection protocol to isolate RNA from cortical, phloem fiber and phloem parenchyma cells throughout adventi- tious root formation.
