NUTRIENTS UPTAKE BY FRUIT AS INFLUENCED BY ORGANIC AND INORGANIC FERTILIZERS

The experiment was conducted at the Central Research Farm of Regional Research Station, New Alluvial Zone, Bidhan Chandra Krishi Viswavidyalaya, Gayeshpur, Nadia, West Bengal, India during the years 2006-2008 to study the effect of organic and inorganic fertilizers on nutrient uptake by mango ‘Himsagar’. The observations on nutrient (nitrogen, phosphorus, potassium, zinc and boron) uptake by fruit (pulp, peel and stone) were recorded against four different organic manure treat¬ments (green manure, farm yard manure, vermicompost and control) and seven treat¬ments of different inorganic nutrients, biofertilizers and growth retardant (paclo¬butrazol). Two Factor Randomized Block Design with split plot technique was followed.
Duncan’s test at 5% level of significance was also followed to compare main effect means if significant for all above mentioned values.
Considering all mean results Application of 850 g N + 425 g P₂O₅ + 1000 g K₂O + 250 g Azospirillum + 250 g phosphate-solubilizing bacteria + 100 g zinc sulphate + 100 g borax/tree/year in combination with green manure showed higher nitrogen (714.63 mg/100 g fruit) and zinc (3.70 mg/100 g fruit) uptake and with vermicompost caused highest phosphorus uptake (62.13 mg/100 g fruit) by whole mango fruit.
Application of 1200 g N + 600 g P₂O₅ + 1200 g K₂O/tree/year in combination with farm yard manure exhibited highest uptake of potassium (565.66 mg/100 g fruit) and boron (0.84 mg/100 g fruit) by whole mango fruit.
