  1. 1. Technology used infood productionIncrease in population will increase demand of foodand need to improve the quantity and quality of foodproductionIn Malaysia, to meet the demand of food,food has to be imported and efforts arebeing carried out by the variousgovernment agencies to diversify foodproductionMethods to improve qualityand quantity of foodproductionn Direct seedingn Hydroponics and aeroponicsn Selective breedingn Tissue culturen Genetic engineeringn Proper soil managementn Biological control
  2. 2. Direct seddingn Seeds sown directly, involve notransplanting hence plants achieve fastergrowth and give higher yields.n Example : cultivation of padiHydroponics and aeroponicsn Hydroponics- growing crop plants inculture solution containing macronutirientsand micronutrientsn Aeroponics – culture solutions are sprayeddirectly to the roots of plantsAdvantages of Hydroponics andaeroponicsn These method require less spacen Can be carried out on a large scalen Does not require the use of insecticides andpesticidesn Can be carry out all year roundn Suitable to carried out at home for homeconsumptionn Example : Tomato, lettuce, spinach
  3. 3. Selective breedingn Different plants and animals withbeneficial characteristics such as highnutritional contents, shorter maturity time,higher yields and higher resistance todisease are selected.n Example : Palm fruitCross between Dura and Pisifera toproduce TeneraTissue culturen Produces clones with the same desiredcharacteristics as the parentn Produce large numbers of young plantswithin a short timeGenetic engineeringn Transfer of useful genes from oneorganism to anothern GEO = genetically engineered organisms,are called transgenic organismsn GMF = genetically modified foodn Eg : wheat, tomatoes, soy beansProper soil management
  4. 4. n To prevent leaching, soil erosion,depletion of soil nutrients and change insoil texturen Increase humus content of soil for bettercrop yieldBiological controln Control pests without using pesticides andinsecticides, for better crop yieldn Eg : the use of snakes and owls to controlrats in oil palm estates
