OP07:Improving lily bulb production through solarization, legume intercropping, manure application and AMF inoculation

  1. 1. 5/27/2010 Fertility Soil Improving lily bulb production TSBF: 2001 through solarization, legume intercropping, manure application and AMF inoculation C. Guadarrama, D. Trejo, I. Barois, M. de los Santos, F. Franco, P. Rodríguez, E. Martínez, J.A. García and M. Ortega WHY LILLIES IN THE SECOND PHASE? Lily farming has been a key cash crop for farmers livelihood in the buffer zone of Santa Marta Reserve. Rural Participatory diagnostic Venustiano Carranza Bulbos de Azucena pobreza del suelo y l Conventional lily farming exerts a strong It is a farmers’ Rotten Bulbs request because impact on soil quality and biodiversity. the bulb Agrochemicals used in lilies culture production had in Tatahuicapan 2005 decrease because of pest.

  4. 4. 5/27/2010 The adoption or popularity of the lilies FOMIX PROJECT experiment is due to: 1-the lilies bulb are highly valued “Lily farming (Lilium longiflorum Thunb.) with 2- the hard work of NGO´s since 20 years biofertilizers and biofumigants in Los 3- the opportunity of being subsidized Tuxtlas, Veracruz, Mexico : an agroecological Fomix Project approach” 2009- 2011 1 Million pesos = 71500 US $ Funded by Federal and State agency CONACYT & Veracruz Government One condition to be financed is to collaborate With users Plots in Transition: •7 communities: Ocotal Grande, Ocotal MEXICO • 55 farmers with a 100 m-2 plot (2000 bulbs of lilies) • 3 treatments in their land: •Solarization +cow manure •Rotation with innoculated Mucuna Jicama (Pachyrhizus erosus ) AMF and BNF Acaulospora mycorrhizal fungi and Bradyrhizobium N fixing bacteria Farmers have put their own strains land and work Sowing bulbs and AMF inoculation Their Labor The committee advanced the money to pay the bulbs for the first year 4
  5. 5. 5/27/2010 The three treatments on the way in the Inoculation of BNF plot of Ocotal Texizapa Regional scale: environmental They start gradient=55 plots adopting and even innovating Farmer plot Variation: BGBD, altitude, vegetation, sun Experimental Plot exposure, land use history: different answers to the best or worst conditions Danger! Thank you! ! • Over production of Lilies They said they take the risk….. 5
