Role of Copper in Mango Nutrition

  1. 1. Internship was conducted at mango research institute multan. The institute was anounced to be established in 2011 by the Govt. of Punjab. It was completed in 2012- 13 at old shujabad road agricultural farm Multan. Total area of MRI is 32.5 acres. From which 2.5 acres have laboratories. 8 acres for residential colony. 20 acres for research purpose and 2 acres are available for raising of nursery.
  2. 2. To conduct research on mango comprising of Horticulture, Plant Pathology, Entomology, Post Harvest & Plant Nutrition discipline. • The successful implementation of this project will surely increase per acre yield of the mango growers by adopting improved and updated research based technology. • This institute will increase the level of awareness and acceptance of standardized technology by making the capacity building of mango growers.
  3. 3. • By the improvement in production technology and its post-harvest curing, the interest of the growers will be increased to produce high quality mango fruits acceptable by meeting the protocols of the national and international market. • Previously an ADP-creation of physical infrastructure on mango under corporate mode at Multan was approved for the period July 2007 to June 2011. Under the scope of this project, it was decided by the Govt. that first, only the funds for the purchase of necessary machinery and equipment and for the construction of the office cum laboratory buildings be provided then after the completion of physical infrastructure, the operation funds would be provided for the functioning of the institute.
  4. 4. • To workout nutrient response & formulate economic fertilizer recommendations, by adopting integrated plant nutrition system OPNS. • To find appropriate time & method of fertilizer application. • To correlate mango responses with soil test value of different nutrients. • To develop technology for amelioration of salinity/sodicity menace by the use of amendments. • To determine the effect of plant growth regulators on mango growth and yield.
  5. 5. The mango tree, are native to Southeastern Asia, where they have been grown for more than 4,000 years. Mango is an excellent source of vitamin A, B and C and contains water, proteins, Sugar, fats, fibers and iron etc. Mango cultivation has now spread to many parts of the tropical and sub-tropical world, where they grow best.
  6. 6. Mangoes were carried to Africa during the 16th century and later found their way aboard Portuguese ships to Brazil in the 1700s. Later, in 1742, mangoes were found growing in the West Indies. In 1860, mangoes were successfully introduced to Florida along the east coast, where only a few varieties were grown. In 1889, the United States Department of Agriculture introduced a grafted variety from India called the "Mulgoa," also known as "Mulgoba" in the United States.
  7. 7. Pakistan is an agricultural country and production of fruits is the part and parcel of this sector. Mango ( is The king of fruits and one of the most important fruit crop in the world as well as in Pakistan. There are more than 1300 varieties of the mango, which are cultivated in the Indo-Pak Sub- continent. There are around 400 known varieties of Mangoes in Pakistan.
  8. 8. It comes in market early in the May and remains in market till August/September. Pakistan is ranked after big producers i.e., India, China, Thailand and Mexico. It’s a tropical, climacteric fruit liked by all due to its taste, flavour and excellent nutritional properties. It is a delicious fruit being grown in more than 100 countries of the world.

  12. 12. Chemical fertilizers have been the key elements in enhancing the fruit production in Pakistan. Fertilizer is the macro-micro nutrients carrier which when applied judiciously to soil or foliage meets the nutrient need of the crop. From the point of view of environmental protection the word judicious is very relevant in the nutrient management. For efficient fertilizer management, split application, appropriate timing, proper placement etc need to be adopted.
  13. 13. Role of Copper • It is important for reproductive growth. • Copper aids in root metabolism and helps in the utilization of proteins. • It is a constituent part of several enzyme system. • Copper have a role in the synthesis and/or stability of chlorophyll and other plant pigments. • Copper also used as a fungicide.
  14. 14. Deficiency Symptoms of Copper • Deficiency symptoms are not common, probably due to the use of copper based fungicidal sprays but may be expressed as poor production, shoots do not mature and bark appears rough. • Narrow, twisted leaves and pale white shoot tips are apparent due to Copper deficiency. • In areas of persistent copper fungicide use, toxicity has been reported and results in decreased levels of other essential elements (P, Fe and Zn) in plant tissue.
  15. 15. • Copper deficiency caused die back of the terminal growth and leaves appear mottled. • Copper deficiency in mango orchards causes long, tender and “S”- shaped branches and leaves with downward curls, both on the lamina and the central vein. Sources of Copper • Copper Sulphate CuSO4.5H2O (24 percent Cu) • CuSO4.H2O (35 percent Cu) • Copper Chelate Na2Cu-EDTA (13 percent Cu) • Copper Oxychloride (for foliar sprays)
  16. 16. Doses of Copper Precaution • Avoid excessive use of phosphorous as it adversely affects utilization of zinc, iron and copper. • Excess of copper induces molybdenum deficiency in crops. Thus application of copper should be within recommended doses. Age of Plant (in years) Copper Sulphate (g) 1 25 10 250
